-GIT v1.5.0.1 Release Notes
-==========================
-
-Fixes since v1.5.0
-------------------
-
-* Documentation updates
-
- - Clarifications and corrections to 1.5.0 release notes.
-
- - The main documentation did not link to git-remote documentation.
-
- - Clarified introductory text of git-rebase documentation.
-
- - Converted remaining mentions of update-index on Porcelain
- documents to git-add/git-rm.
-
- - Some i18n.* configuration variables were incorrectly
- described as core.*; fixed.
-
-* Bugfixes
-
- - git-add and git-update-index on a filesystem on which
- executable bits are unreliable incorrectly reused st_mode
- bits even when the path changed between symlink and regular
- file.
-
- - git-daemon marks the listening sockets with FD_CLOEXEC so
- that it won't be leaked into the children.
-
- - segfault from git-blame when the mandatory pathname
- parameter was missing was fixed; usage() message is given
- instead.
-
- - git-rev-list did not read $GIT_DIR/config file, which means
- that did not honor i18n.logoutputencoding correctly.
-
-* Tweaks
-
- - sliding mmap() inefficiently mmaped the same region of a
- packfile with an access pattern that used objects in the
- reverse order. This has been made more efficient.

-GIT v1.5.0.2 Release Notes
-==========================
-
-Fixes since v1.5.0.1
---------------------
-
-* Bugfixes
-
- - Automated merge conflict handling when changes to symbolic
- links conflicted were completely broken. The merge-resolve
- strategy created a regular file with conflict markers in it
- in place of the symbolic link. The default strategy,
- merge-recursive was even more broken. It removed the path
- that was pointed at by the symbolic link. Both of these
- problems have been fixed.
-
- - 'git diff maint master next' did not correctly give combined
- diff across three trees.
-
- - 'git fast-import' portability fix for Solaris.
-
- - 'git show-ref --verify' without arguments did not error out
- but segfaulted.
-
- - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
- slashes after a/ and b/.
-
- - 'git format-patch' produced too long filenames if the commit
- message had too long line at the beginning.
-
- - Running 'make all' and then without changing anything
- running 'make install' still rebuilt some files. This
- was inconvenient when building as yourself and then
- installing as root (especially problematic when the source
- directory is on NFS and root is mapped to nobody).
-
- - 'git-rerere' failed to deal with two unconflicted paths that
- sorted next to each other.
-
- - 'git-rerere' attempted to open(2) a symlink and failed if
- there was a conflict. Since a conflicting change to a
- symlink would not benefit from rerere anyway, the command
- now ignores conflicting changes to symlinks.
-
- - 'git-repack' did not like to pass more than 64 arguments
- internally to underlying 'rev-list' logic, which made it
- impossible to repack after accumulating many (small) packs
- in the repository.
-
- - 'git-diff' to review the combined diff during a conflicted
- merge were not reading the working tree version correctly
- when changes to a symbolic link conflicted. It should have
- read the data using readlink(2) but read from the regular
- file the symbolic link pointed at.
-
- - 'git-remote' did not like period in a remote's name.
-
-* Documentation updates
-
- - added and clarified core.bare, core.legacyheaders configurations.
-
- - updated "git-clone --depth" documentation.
-
-
-* Assorted git-gui fixes.

-
- - 'git-mailinfo' choke when a logical header line was too long.
-
- - 'git show A..B' did not error out. Negative ref ("not A" in
- this example) does not make sense for the purpose of the

-GIT v1.5.0 Release Notes
-========================
-
-Old news
---------
-
-This section is for people who are upgrading from ancient
-versions of git. Although all of the changes in this section
-happened before the current v1.4.4 release, they are summarized
-here in the v1.5.0 release notes for people who skipped earlier
-versions.
-
-As of git v1.5.0 there are some optional features that changes
-the repository to allow data to be stored and transferred more
-efficiently. These features are not enabled by default, as they
-will make the repository unusable with older versions of git.
-Specifically, the available options are:
-
- - There is a configuration variable core.legacyheaders that
- changes the format of loose objects so that they are more
- efficient to pack and to send out of the repository over git
- native protocol, since v1.4.2. However, loose objects
- written in the new format cannot be read by git older than
- that version; people fetching from your repository using
- older clients over dumb transports (e.g. http) using older
- versions of git will also be affected.
-
- To let git use the new loose object format, you have to
- set core.legacyheaders to false.
-
- - Since v1.4.3, configuration repack.usedeltabaseoffset allows
- packfile to be created in more space efficient format, which
- cannot be read by git older than that version.
-
- To let git use the new format for packfiles, you have to
- set repack.usedeltabaseoffset to true.
-
-The above two new features are not enabled by default and you
-have to explicitly ask for them, because they make repositories
-unreadable by older versions of git, and in v1.5.0 we still do
-not enable them by default for the same reason. We will change
-this default probably 1 year after 1.4.2's release, when it is
-reasonable to expect everybody to have new enough version of
-git.
-
- - 'git pack-refs' appeared in v1.4.4; this command allows tags
- to be accessed much more efficiently than the traditional
- 'one-file-per-tag' format. Older git-native clients can
- still fetch from a repository that packed and pruned refs
- (the server side needs to run the up-to-date version of git),
- but older dumb transports cannot. Packing of refs is done by
- an explicit user action, either by use of "git pack-refs
- --prune" command or by use of "git gc" command.
-
- - 'git -p' to paginate anything -- many commands do pagination
- by default on a tty. Introduced between v1.4.1 and v1.4.2;
- this may surprise old timers.
-
- - 'git archive' superseded 'git tar-tree' in v1.4.3;
-
- - 'git cvsserver' was new invention in v1.3.0;
-
- - 'git repo-config', 'git grep', 'git rebase' and 'gitk' were
- seriously enhanced during v1.4.0 timeperiod.
-
- - 'gitweb' became part of git.git during v1.4.0 timeperiod and
- seriously modified since then.
-
- - reflog is an v1.4.0 invention. This allows you to name a
- revision that a branch used to be at (e.g. "git diff
- master@{yesterday} master" allows you to see changes since
- yesterday's tip of the branch).
-
-
-Updates in v1.5.0 since v1.4.4 series
--------------------------------------
-
-* Index manipulation
-
- - git-add is to add contents to the index (aka "staging area"
- for the next commit), whether the file the contents happen to
- be is an existing one or a newly created one.
-
- - git-add without any argument does not add everything
- anymore. Use 'git-add .' instead. Also you can add
- otherwise ignored files with an -f option.
-
- - git-add tries to be more friendly to users by offering an
- interactive mode ("git-add -i").
-
- - git-commit <path> used to refuse to commit if <path> was
- different between HEAD and the index (i.e. update-index was
- used on it earlier). This check was removed.
-
- - git-rm is much saner and safer. It is used to remove paths
- from both the index file and the working tree, and makes sure
- you are not losing any local modification before doing so.
-
- - git-reset <tree> <paths>... can be used to revert index
- entries for selected paths.
-
- - git-update-index is much less visible. Many suggestions to
- use the command in git output and documentation have now been
- replaced by simpler commands such as "git add" or "git rm".
-
-
-* Repository layout and objects transfer
-
- - The data for origin repository is stored in the configuration
- file $GIT_DIR/config, not in $GIT_DIR/remotes/, for newly
- created clones. The latter is still supported and there is
- no need to convert your existing repository if you are
- already comfortable with your workflow with the layout.
-
- - git-clone always uses what is known as "separate remote"
- layout for a newly created repository with a working tree.
-
- A repository with the separate remote layout starts with only
- one default branch, 'master', to be used for your own
- development. Unlike the traditional layout that copied all
- the upstream branches into your branch namespace (while
- renaming their 'master' to your 'origin'), the new layout
- puts upstream branches into local "remote-tracking branches"
- with their own namespace. These can be referenced with names
- such as "origin/$upstream_branch_name" and are stored in
- .git/refs/remotes rather than .git/refs/heads where normal
- branches are stored.
-
- This layout keeps your own branch namespace less cluttered,
- avoids name collision with your upstream, makes it possible
- to automatically track new branches created at the remote
- after you clone from it, and makes it easier to interact with
- more than one remote repository (you can use "git remote" to
- add other repositories to track). There might be some
- surprises:
-
- * 'git branch' does not show the remote tracking branches.
- It only lists your own branches. Use '-r' option to view
- the tracking branches.
-
- * If you are forking off of a branch obtained from the
- upstream, you would have done something like 'git branch
- my-next next', because traditional layout dropped the
- tracking branch 'next' into your own branch namespace.
- With the separate remote layout, you say 'git branch next
- origin/next', which allows you to use the matching name
- 'next' for your own branch. It also allows you to track a
- remote other than 'origin' (i.e. where you initially cloned
- from) and fork off of a branch from there the same way
- (e.g. "git branch mingw j6t/master").
-
- Repositories initialized with the traditional layout continue
- to work.
-
- - New branches that appear on the origin side after a clone is
- made are also tracked automatically. This is done with an
- wildcard refspec "refs/heads/*:refs/remotes/origin/*", which
- older git does not understand, so if you clone with 1.5.0,
- you would need to downgrade remote.*.fetch in the
- configuration file to specify each branch you are interested
- in individually if you plan to fetch into the repository with
- older versions of git (but why would you?).
-
- - Similarly, wildcard refspec "refs/heads/*:refs/remotes/me/*"
- can be given to "git-push" command to update the tracking
- branches that is used to track the repository you are pushing
- from on the remote side.
-
- - git-branch and git-show-branch know remote tracking branches
- (use the command line switch "-r" to list only tracked branches).
-
- - git-push can now be used to delete a remote branch or a tag.
- This requires the updated git on the remote side (use "git
- push <remote> :refs/heads/<branch>" to delete "branch").
-
- - git-push more aggressively keeps the transferred objects
- packed. Earlier we recommended to monitor amount of loose
- objects and repack regularly, but you should repack when you
- accumulated too many small packs this way as well. Updated
- git-count-objects helps you with this.
-
- - git-fetch also more aggressively keeps the transferred objects
- packed. This behavior of git-push and git-fetch can be
- tweaked with a single configuration transfer.unpacklimit (but
- usually there should not be any need for a user to tweak it).
-
- - A new command, git-remote, can help you manage your remote
- tracking branch definitions.
-
- - You may need to specify explicit paths for upload-pack and/or
- receive-pack due to your ssh daemon configuration on the
- other end. This can now be done via remote.*.uploadpack and
- remote.*.receivepack configuration.
-
-
-* Bare repositories
-
- - Certain commands change their behavior in a bare repository
- (i.e. a repository without associated working tree). We use
- a fairly conservative heuristic (if $GIT_DIR is ".git", or
- ends with "/.git", the repository is not bare) to decide if a
- repository is bare, but "core.bare" configuration variable
- can be used to override the heuristic when it misidentifies
- your repository.
-
- - git-fetch used to complain updating the current branch but
- this is now allowed for a bare repository. So is the use of
- 'git-branch -f' to update the current branch.
-
- - Porcelain-ish commands that require a working tree refuses to
- work in a bare repository.
-
-
-* Reflog
-
- - Reflog records the history from the view point of the local
- repository. In other words, regardless of the real history,
- the reflog shows the history as seen by one particular
- repository (this enables you to ask "what was the current
- revision in _this_ repository, yesterday at 1pm?"). This
- facility is enabled by default for repositories with working
- trees, and can be accessed with the "branch@{time}" and
- "branch@{Nth}" notation.
-
- - "git show-branch" learned showing the reflog data with the
- new -g option. "git log" has -g option to view reflog
- entries in a more verbose manner.
-
- - git-branch knows how to rename branches and moves existing
- reflog data from the old branch to the new one.
-
- - In addition to the reflog support in v1.4.4 series, HEAD
- reference maintains its own log. "HEAD@{5.minutes.ago}"
- means the commit you were at 5 minutes ago, which takes
- branch switching into account. If you want to know where the
- tip of your current branch was at 5 minutes ago, you need to
- explicitly say its name (e.g. "master@{5.minutes.ago}") or
- omit the refname altogether i.e. "@{5.minutes.ago}".
-
- - The commits referred to by reflog entries are now protected
- against pruning. The new command "git reflog expire" can be
- used to truncate older reflog entries and entries that refer
- to commits that have been pruned away previously with older
- versions of git.
-
- Existing repositories that have been using reflog may get
- complaints from fsck-objects and may not be able to run
- git-repack, if you had run git-prune from older git; please
- run "git reflog expire --stale-fix --all" first to remove
- reflog entries that refer to commits that are no longer in
- the repository when that happens.
-
-
-* Crufts removal
-
- - We used to say "old commits are retrievable using reflog and
- 'master@{yesterday}' syntax as long as you haven't run
- git-prune". We no longer have to say the latter half of the
- above sentence, as git-prune does not remove things reachable
- from reflog entries.
-
- - There is a toplevel garbage collector script, 'git-gc', that
- runs periodic cleanup functions, including 'git-repack -a -d',
- 'git-reflog expire', 'git-pack-refs --prune', and 'git-rerere
- gc'.
-
- - The output from fsck ("fsck-objects" is called just "fsck"
- now, but the old name continues to work) was needlessly
- alarming in that it warned missing objects that are reachable
- only from dangling objects. This has been corrected and the
- output is much more useful.
-
-
-* Detached HEAD
-
- - You can use 'git-checkout' to check out an arbitrary revision
- or a tag as well, instead of named branches. This will
- dissociate your HEAD from the branch you are currently on.
-
- A typical use of this feature is to "look around". E.g.
-
- $ git checkout v2.6.16
- ... compile, test, etc.
- $ git checkout v2.6.17
- ... compile, test, etc.
-
- - After detaching your HEAD, you can go back to an existing
- branch with usual "git checkout $branch". Also you can
- start a new branch using "git checkout -b $newbranch" to
- start a new branch at that commit.
-
- - You can even pull from other repositories, make merges and
- commits while your HEAD is detached. Also you can use "git
- reset" to jump to arbitrary commit, while still keeping your
- HEAD detached.
-
- Remember that a detached state is volatile, i.e. it will be forgotten
- as soon as you move away from it with the checkout or reset command,
- unless a branch is created from it as mentioned above. It is also
- possible to rescue a lost detached state from the HEAD reflog.
-
-
-* Packed refs
-
- - Repositories with hundreds of tags have been paying large
- overhead, both in storage and in runtime, due to the
- traditional one-ref-per-file format. A new command,
- git-pack-refs, can be used to "pack" them in more efficient
- representation (you can let git-gc do this for you).
-
- - Clones and fetches over dumb transports are now aware of
- packed refs and can download from repositories that use
- them.
-
-
-* Configuration
-
- - configuration related to color setting are consolidated under
- color.* namespace (older diff.color.*, status.color.* are
- still supported).
-
- - 'git-repo-config' command is accessible as 'git-config' now.
-
-
-* Updated features
-
- - git-describe uses better criteria to pick a base ref. It
- used to pick the one with the newest timestamp, but now it
- picks the one that is topologically the closest (that is,
- among ancestors of commit C, the ref T that has the shortest
- output from "git-rev-list T..C" is chosen).
-
- - git-describe gives the number of commits since the base ref
- between the refname and the hash suffix. E.g. the commit one
- before v2.6.20-rc6 in the kernel repository is:
-
- v2.6.20-rc5-306-ga21b069
-
- which tells you that its object name begins with a21b069,
- v2.6.20-rc5 is an ancestor of it (meaning, the commit
- contains everything -rc5 has), and there are 306 commits
- since v2.6.20-rc5.
-
- - git-describe with --abbrev=0 can be used to show only the
- name of the base ref.
-
- - git-blame learned a new option, --incremental, that tells it
- to output the blames as they are assigned. A sample script
- to use it is also included as contrib/blameview.
-
- - git-blame starts annotating from the working tree by default.
-
-
-* Less external dependency
-
- - We no longer require the "merge" program from the RCS suite.
- All 3-way file-level merges are now done internally.
-
- - The original implementation of git-merge-recursive which was
- in Python has been removed; we have a C implementation of it
- now.
-
- - git-shortlog is no longer a Perl script. It no longer
- requires output piped from git-log; it can accept revision
- parameters directly on the command line.
-
-
-* I18n
-
- - We have always encouraged the commit message to be encoded in
- UTF-8, but the users are allowed to use legacy encoding as
- appropriate for their projects. This will continue to be the
- case. However, a non UTF-8 commit encoding _must_ be
- explicitly set with i18n.commitencoding in the repository
- where a commit is made; otherwise git-commit-tree will
- complain if the log message does not look like a valid UTF-8
- string.
-
- - The value of i18n.commitencoding in the originating
- repository is recorded in the commit object on the "encoding"
- header, if it is not UTF-8. git-log and friends notice this,
- and reencodes the message to the log output encoding when
- displaying, if they are different. The log output encoding
- is determined by "git log --encoding=<encoding>",
- i18n.logoutputencoding configuration, or i18n.commitencoding
- configuration, in the decreasing order of preference, and
- defaults to UTF-8.
-
- - Tools for e-mailed patch application now default to -u
- behavior; i.e. it always re-codes from the e-mailed encoding
- to the encoding specified with i18n.commitencoding. This
- unfortunately forces projects that have happily been using a
- legacy encoding without setting i18n.commitencoding to set
- the configuration, but taken with other improvement, please
- excuse us for this very minor one-time inconvenience.
-
-
-* e-mailed patches
-
- - See the above I18n section.
-
- - git-format-patch now enables --binary without being asked.
- git-am does _not_ default to it, as sending binary patch via
- e-mail is unusual and is harder to review than textual
- patches and it is prudent to require the person who is
- applying the patch to explicitly ask for it.
-
- - The default suffix for git-format-patch output is now ".patch",
- not ".txt". This can be changed with --suffix=.txt option,
- or setting the config variable "format.suffix" to ".txt".
-
-
-* Foreign SCM interfaces
-
- - git-svn now requires the Perl SVN:: libraries, the
- command-line backend was too slow and limited.
-
- - the 'commit' subcommand of git-svn has been renamed to
- 'set-tree', and 'dcommit' is the recommended replacement for
- day-to-day work.
-
- - git fast-import backend.
-
-
-* User support
-
- - Quite a lot of documentation updates.
-
- - Bash completion scripts have been updated heavily.
-
- - Better error messages for often used Porcelainish commands.
-
- - Git GUI. This is a simple Tk based graphical interface for
- common Git operations.
-
-
-* Sliding mmap
-
- - We used to assume that we can mmap the whole packfile while
- in use, but with a large project this consumes huge virtual
- memory space and truly huge ones would not fit in the
- userland address space on 32-bit platforms. We now mmap huge
- packfile in pieces to avoid this problem.
-
-
-* Shallow clones
-
- - There is a partial support for 'shallow' repositories that
- keeps only recent history. A 'shallow clone' is created by
- specifying how deep that truncated history should be
- (e.g. "git clone --depth 5 git://some.where/repo.git").
-
- Currently a shallow repository has number of limitations:
-
- - Cloning and fetching _from_ a shallow clone are not
- supported (nor tested -- so they might work by accident but
- they are not expected to).
-
- - Pushing from nor into a shallow clone are not expected to
- work.
-
- - Merging inside a shallow repository would work as long as a
- merge base is found in the recent history, but otherwise it
- will be like merging unrelated histories and may result in
- huge conflicts.
-
- but this would be more than adequate for people who want to
- look at near the tip of a big project with a deep history and
- send patches in e-mail format.

-GIT v1.5.1.1 Release Notes
-==========================
-
-Fixes since v1.5.1
-------------------
-
-* Documentation updates
-
- - The --left-right option of rev-list and friends is documented.
-
- - The documentation for cvsimport has been majorly improved.
-
- - "git-show-ref --exclude-existing" was documented.
-
-* Bugfixes
-
- - The implementation of -p option in "git cvsexportcommit" had
- the meaning of -C (context reduction) option wrong, and
- loosened the context requirements when it was told to be
- strict.
-
- - "git cvsserver" did not behave like the real cvsserver when
- client side removed a file from the working tree without
- doing anything else on the path. In such a case, it should
- restore it from the checked out revision.
-
- - "git fsck" issued an alarming error message on detached
- HEAD. It is not an error since at least 1.5.0.
-
- - "git send-email" produced of References header of unbounded length;
- fixed this with line-folding.
-
- - "git archive" to download from remote site should not
- require you to be in a git repository, but it incorrectly
- did.
-
- - "git apply" ignored -p<n> for "diff --git" formatted
- patches.
-
- - "git rerere" recorded a conflict that had one side empty
- (the other side adds) incorrectly; this made merging in the
- other direction fail to use previously recorded resolution.
-
- - t4200 test was broken where "wc -l" pads its output with
- spaces.
-
- - "git branch -m old new" to rename branch did not work
- without a configuration file in ".git/config".
-
- - The sample hook for notification e-mail was misnamed.
-
- - gitweb did not show type-changing patch correctly in the
- blobdiff view.
-
- - git-svn did not error out with incorrect command line options.
-
- - git-svn fell into an infinite loop when insanely long commit
- message was found.
-
- - git-svn dcommit and rebase was confused by patches that were
- merged from another branch that is managed by git-svn.
-
- - git-svn used to get confused when globbing remote branch/tag
- spec (e.g. "branches = proj/branches/*:refs/remotes/origin/*")
- is used and there was a plain file that matched the glob.

-GIT v1.5.1.2 Release Notes
-==========================
-
-Fixes since v1.5.1.1
---------------------
-
-* Bugfixes
-
- - "git clone" over http from a repository that has lost the
- loose refs by running "git pack-refs" were broken (a code to
- deal with this was added to "git fetch" in v1.5.0, but it
- was missing from "git clone").
-
- - "git diff a/ b/" incorrectly fell in "diff between two
- filesystem objects" codepath, when the user most likely
- wanted to limit the extent of output to two tracked
- directories.
-
- - git-quiltimport had the same bug as we fixed for
- git-applymbox in v1.5.1.1 -- it gave an alarming "did not
- have any patch" message (but did not actually fail and was
- harmless).
-
- - various git-svn fixes.
-
- - Sample update hook incorrectly always refused requests to
- delete branches through push.
-
- - git-blame on a very long working tree path had buffer
- overrun problem.
-
- - git-apply did not like to be fed two patches in a row that created
- and then modified the same file.
-
- - git-svn was confused when a non-project was stored directly under
- trunk/, branches/ and tags/.
-
- - git-svn wants the Error.pm module that was at least as new
- as what we ship as part of git; install ours in our private
- installation location if the one on the system is older.
-
- - An earlier update to command line integer parameter parser was
- botched and made 'update-index --cacheinfo' completely useless.
-
-
-* Documentation updates
-
- - Various documentation updates from J. Bruce Fields, Frank
- Lichtenheld, Alex Riesen and others. Andrew Ruder started a
- war on undocumented options.

-GIT v1.5.1.3 Release Notes
-==========================
-
-Fixes since v1.5.1.2
---------------------
-
-* Bugfixes
-
- - git-add tried to optimize by finding common leading
- directories across its arguments but botched, causing very
- confused behaviour.
-
- - unofficial rpm.spec file shipped with git was letting
- ETC_GITCONFIG set to /usr/etc/gitconfig. Tweak the official
- Makefile to make it harder for distro people to make the
- same mistake, by setting the variable to /etc/gitconfig if
- prefix is set to /usr.
-
- - git-svn inconsistently stripped away username from the URL
- only when svnsync_props was in use.
-
- - git-svn got confused when handling symlinks on Mac OS.
-
- - git-send-email was not quoting recipient names that have
- period '.' in them. Also it did not allow overriding
- envelope sender, which made it impossible to send patches to
- certain subscriber-only lists.
-
- - built-in write_tree() routine had a sequence that renamed a
- file that is still open, which some systems did not like.
-
- - when memory is very tight, sliding mmap code to read
- packfiles incorrectly closed the fd that was still being
- used to read the pack.
-
- - import-tars contributed front-end for fastimport was passing
- wrong directory modes without checking.
-
- - git-fastimport trusted its input too much and allowed to
- create corrupt tree objects with entries without a name.
-
- - git-fetch needlessly barfed when too long reflog action
- description was given by the caller.
-
-Also contains various documentation updates.

-GIT v1.5.1.4 Release Notes

-
-Fixes since v1.5.1.3

-
-* Bugfixes
-
- - "git-http-fetch" did not work around a bug in libcurl
- earlier than 7.16 (curl_multi_remove_handle() was broken).
-
- - "git cvsserver" handles a file that was once removed and
- then added again correctly.
-
- - import-tars script (in contrib/) handles GNU tar archives
- that contain pathnames longer than 100 bytes (long-link

-GIT v1.5.1 Release Notes
-========================
-
-Updates since v1.5.0
---------------------
-
-* Deprecated commands and options.
-
- - git-diff-stages and git-resolve have been removed.
-
-* New commands and options.
-
- - "git log" and friends take --reverse, which instructs them
- to give their output in the order opposite from their usual.
- They typically output from new to old, but with this option
- their output would read from old to new. "git shortlog"
- usually lists older commits first, but with this option,
- they are shown from new to old.
-
- - "git log --pretty=format:<string>" to allow more flexible
- custom log output.
-
- - "git diff" learned --ignore-space-at-eol. This is a weaker
- form of --ignore-space-change.
-
- - "git diff --no-index pathA pathB" can be used as diff
- replacement with git specific enhancements.
-
- - "git diff --no-index" can read from '-' (standard input).
-
- - "git diff" also learned --exit-code to exit with non-zero
- status when it found differences. In the future we might
- want to make this the default but that would be a rather big
- backward incompatible change; it will stay as an option for
- now.
-
- - "git diff --quiet" is --exit-code with output turned off,
- meant for scripted use to quickly determine if there is any
- tree-level difference.
-
- - Textual patch generation with "git diff" without -w/-b
- option has been significantly optimized. "git blame" got
- faster because of the same change.
-
- - "git log" and "git rev-list" has been optimized
- significantly when they are used with pathspecs.
-
- - "git branch --track" can be used to set up configuration
- variables to help it easier to base your work on branches
- you track from a remote site.
-
- - "git format-patch --attach" now emits attachments. Use
- --inline to get an inlined multipart/mixed.
-
- - "git name-rev" learned --refs=<pattern>, to limit the tags
- used for naming the given revisions only to the ones
- matching the given pattern.
-
- - "git remote update" is to run "git fetch" for defined remotes
- to update tracking branches.
-
- - "git cvsimport" can now take '-d' to talk with a CVS
- repository different from what are recorded in CVS/Root
- (overriding it with environment CVSROOT does not work).
-
- - "git bundle" can help sneaker-netting your changes between
- repositories.
-
- - "git mergetool" can help 3-way file-level conflict
- resolution with your favorite graphical merge tools.
-
- - A new configuration "core.symlinks" can be used to disable
- symlinks on filesystems that do not support them; they are
- checked out as regular files instead.
-
- - You can name a commit object with its first line of the
- message. The syntax to use is ':/message text'. E.g.
-
- $ git show ":/object name: introduce ':/<oneline prefix>' notation"
-
- means the same thing as:
-
- $ git show 28a4d940443806412effa246ecc7768a21553ec7
-
- - "git bisect" learned a new command "run" that takes a script
- to run after each revision is checked out to determine if it
- is good or bad, to automate the bisection process.
-
- - "git log" family learned a new traversal option --first-parent,
- which does what the name suggests.
-
-
-* Updated behavior of existing commands.
-
- - "git-merge-recursive" used to barf when there are more than
- one common ancestors for the merge, and merging them had a
- rename/rename conflict. This has been fixed.
-
- - "git fsck" does not barf on corrupt loose objects.
-
- - "git rm" does not remove newly added files without -f.
-
- - "git archimport" allows remapping when coming up with git
- branch names from arch names.
-
- - git-svn got almost a rewrite.
-
- - core.autocrlf configuration, when set to 'true', makes git
- to convert CRLF at the end of lines in text files to LF when
- reading from the filesystem, and convert in reverse when
- writing to the filesystem. The variable can be set to
- 'input', in which case the conversion happens only while
- reading from the filesystem but files are written out with
- LF at the end of lines. Currently, which paths to consider
- 'text' (i.e. be subjected to the autocrlf mechanism) is
- decided purely based on the contents, but the plan is to
- allow users to explicitly override this heuristic based on
- paths.
-
- - The behavior of 'git-apply', when run in a subdirectory,
- without --index nor --cached were inconsistent with that of
- the command with these options. This was fixed to match the
- behavior with --index. A patch that is meant to be applied
- with -p1 from the toplevel of the project tree can be
- applied with any custom -p<n> option. A patch that is not
- relative to the toplevel needs to be applied with -p<n>
- option with or without --index (or --cached).
-
- - "git diff" outputs a trailing HT when pathnames have embedded
- SP on +++/--- header lines, in order to help "GNU patch" to
- parse its output. "git apply" was already updated to accept
- this modified output format since ce74618d (Sep 22, 2006).
-
- - "git cvsserver" runs hooks/update and honors its exit status.
-
- - "git cvsserver" can be told to send everything with -kb.
-
- - "git diff --check" also honors the --color output option.
-
- - "git name-rev" used to stress the fact that a ref is a tag too
- much, by saying something like "v1.2.3^0~22". It now says
- "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
- not talk about an ancestor of the commit that is tagged, which
- makes sense).
-
- - "git rev-list --boundary" now shows boundary markers for the
- commits omitted by --max-age and --max-count condition.
-
- - The configuration mechanism now reads $(prefix)/etc/gitconfig.
-
- - "git apply --verbose" shows what preimage lines were wanted
- when it couldn't find them.
-
- - "git status" in a read-only repository got a bit saner.
-
- - "git fetch" (hence "git clone" and "git pull") are less
- noisy when the output does not go to tty.
-
- - "git fetch" between repositories with many refs were slow
- even when there are not many changes that needed
- transferring. This has been sped up by partially rewriting
- the heaviest parts in C.
-
- - "git mailinfo" which splits an e-mail into a patch and the
- meta-information was rewritten, thanks to Don Zickus. It
- handles nested multipart better. The command was broken for
- a brief period on 'master' branch since 1.5.0 but the
- breakage is fixed now.
-
- - send-email learned configurable bcc and chain-reply-to.
-
- - "git remote show $remote" also talks about branches that
- would be pushed if you run "git push remote".
-
- - Using objects from packs is now seriously optimized by clever
- use of a cache. This should be most noticeable in git-log
- family of commands that involve reading many tree objects.
- In addition, traversing revisions while filtering changes
- with pathspecs is made faster by terminating the comparison
- between the trees as early as possible.
-
-
-* Hooks
-
- - The part to send out notification e-mails was removed from
- the sample update hook, as it was not an appropriate place
- to do so. The proper place to do this is the new post-receive
- hook. An example hook has been added to contrib/hooks/.
-
-
-* Others
-
- - git-revert, git-gc and git-cherry-pick are now built-ins.
-
-Fixes since v1.5.0
-------------------
-
-These are all in v1.5.0.x series.
-
-* Documentation updates
-
- - Clarifications and corrections to 1.5.0 release notes.
-
- - The main documentation did not link to git-remote documentation.
-
- - Clarified introductory text of git-rebase documentation.
-
- - Converted remaining mentions of update-index on Porcelain
- documents to git-add/git-rm.
-
- - Some i18n.* configuration variables were incorrectly
- described as core.*; fixed.
-
- - added and clarified core.bare, core.legacyheaders configurations.
-
- - updated "git-clone --depth" documentation.
-
- - user-manual updates.
-
- - Options to 'git remote add' were described insufficiently.
-
- - Configuration format.suffix was not documented.
-
- - Other formatting and spelling fixes.
-
- - user-manual has better cross references.
-
- - gitweb installation/deployment procedure is now documented.
-
-
-* Bugfixes
-
- - git-upload-pack closes unused pipe ends; earlier this caused
- many zombies to hang around.
-
- - git-rerere was recording the contents of earlier hunks
- duplicated in later hunks. This prevented resolving the same
- conflict when performing the same merge the other way around.
-
- - git-add and git-update-index on a filesystem on which
- executable bits are unreliable incorrectly reused st_mode
- bits even when the path changed between symlink and regular
- file.
-
- - git-daemon marks the listening sockets with FD_CLOEXEC so
- that it won't be leaked into the children.
-
- - segfault from git-blame when the mandatory pathname
- parameter was missing was fixed; usage() message is given
- instead.
-
- - git-rev-list did not read $GIT_DIR/config file, which means
- that did not honor i18n.logoutputencoding correctly.
-
- - Automated merge conflict handling when changes to symbolic
- links conflicted were completely broken. The merge-resolve
- strategy created a regular file with conflict markers in it
- in place of the symbolic link. The default strategy,
- merge-recursive was even more broken. It removed the path
- that was pointed at by the symbolic link. Both of these
- problems have been fixed.
-
- - 'git diff maint master next' did not correctly give combined
- diff across three trees.
-
- - 'git fast-import' portability fix for Solaris.
-
- - 'git show-ref --verify' without arguments did not error out
- but segfaulted.
-
- - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
- slashes after a/ and b/.
-
- - 'git format-patch' produced too long filenames if the commit
- message had too long line at the beginning.
-
- - Running 'make all' and then without changing anything
- running 'make install' still rebuilt some files. This
- was inconvenient when building as yourself and then
- installing as root (especially problematic when the source
- directory is on NFS and root is mapped to nobody).
-
- - 'git-rerere' failed to deal with two unconflicted paths that
- sorted next to each other.
-
- - 'git-rerere' attempted to open(2) a symlink and failed if
- there was a conflict. Since a conflicting change to a
- symlink would not benefit from rerere anyway, the command
- now ignores conflicting changes to symlinks.
-
- - 'git-repack' did not like to pass more than 64 arguments
- internally to underlying 'rev-list' logic, which made it
- impossible to repack after accumulating many (small) packs
- in the repository.
-
- - 'git-diff' to review the combined diff during a conflicted
- merge were not reading the working tree version correctly
- when changes to a symbolic link conflicted. It should have
- read the data using readlink(2) but read from the regular
- file the symbolic link pointed at.
-
- - 'git-remote' did not like period in a remote's name.
-
- - 'git.el' honors the commit coding system from the configuration.
-
- - 'blameview' in contrib/ correctly digs deeper when a line is
- clicked.
-
- - 'http-push' correctly makes sure the remote side has leading
- path. Earlier it started in the middle of the path, and
- incorrectly.
-
- - 'git-merge' did not exit with non-zero status when the
- working tree was dirty and cannot fast forward. It does
- now.
-
- - 'cvsexportcommit' does not lose yet-to-be-used message file.
-
- - int-vs-size_t typefix when running combined diff on files
- over 2GB long.
-
- - 'git apply --whitespace=strip' should not touch unmodified
- lines.
-
- - 'git-mailinfo' choke when a logical header line was too long.
-
- - 'git show A..B' did not error out. Negative ref ("not A" in
- this example) does not make sense for the purpose of the
- command, so now it errors out.
-
- - 'git fmt-merge-msg --file' without file parameter did not
- correctly error out.
-
- - 'git archimport' barfed upon encountering a commit without
- summary.
-
- - 'git index-pack' did not protect itself from getting a short
- read out of pread(2).
-
- - 'git http-push' had a few buffer overruns.
-
- - Build dependency fixes to rebuild fetch.o when other headers
- change.
-
- - git.el does not add duplicate sign-off lines.
-
- - git-commit shows the full stat of the resulting commit, not
- just about the files in the current directory, when run from
- a subdirectory.
-
- - "git-checkout -m '@{8 hours ago}'" had a funny failure from
- eval; fixed.
-
- - git-merge (hence git-pull) did not refuse fast-forwarding
- when the working tree had local changes that would have
- conflicted with it.
-
- - a handful small fixes to gitweb.
-
- - build procedure for user-manual is fixed not to require locally
- installed stylesheets.
-
- - "git commit $paths" on paths whose earlier contents were
- already updated in the index were failing out.
-
-
-* Tweaks
-
- - sliding mmap() inefficiently mmaped the same region of a
- packfile with an access pattern that used objects in the
- reverse order. This has been made more efficient.

-
-* Usability fix
-
- - git-gui is shipped with its updated blame interface. It is
- rumored that the older one was not just unusable but was
- active health hazard, but this one is actually pretty.
- Please see for yourself.
-
-* Bugfixes
-
- - "git checkout fubar" was utterly confused when there is a
- branch fubar and a tag fubar at the same time. It correctly
- checks out the branch fubar now.
-
- - "git clone /path/foo" to clone a local /path/foo.git
- repository left an incorrect configuration.
-
- - "git send-email" correctly unquotes RFC 2047 quoted names in
- the patch-email before using their values.
-
- - We did not accept number of seconds since epoch older than
- year 2000 as a valid timestamp. We now interpret positive
- integers more than 8 digits as such, which allows us to
- express timestamps more recent than March 1973.
-
- - git-cvsimport did not work when you have GIT_DIR to point
- your repository at a nonstandard location.
-
- - Some systems (notably, Solaris) lack hstrerror() to make
- h_errno human readable; prepare a replacement
- implementation.
-
- - .gitignore file listed git-core.spec but what we generate is
- git.spec, and nobody noticed for a long time.
-
- - "git-merge-recursive" does not try to run file level merge
- on binary files.
-
- - "git-branch --track" did not create tracking configuration
- correctly when the branch name had slash in it.
-
- - The email address of the user specified with user.email
- configuration was overridden by EMAIL environment variable.
-
- - The tree parser did not warn about tree entries with
- nonsense file modes, and assumed they must be blobs.
-
- - "git log -z" without any other request to generate diff still
- invoked the diff machinery, wasting cycles.
-
-* Documentation
-
- - Many updates to fix stale or missing documentation.
-
- - Although our documentation was primarily meant to be formatted
- with AsciiDoc7, formatting with AsciiDoc8 is supported better.

---------------------
-
- * Bugfixes
-
- - Version 2 pack index format was introduced in version 1.5.2
- to support pack files that has offset that cannot be
- represented in 32-bit. The runtime code to validate such
- an index mishandled such an index for an empty pack.
-
- - Commit walkers (most notably, fetch over http protocol)
- tried to traverse commit objects contained in trees (aka
- subproject); they shouldn't.
-
- - A build option NO_R_TO_GCC_LINKER was not explained in Makefile
- comment correctly.
-
- * Documentation Fixes and Updates
-
- - git-config --regexp was not documented properly.
-
- - git-repack -a was not documented properly.
-
- - git-remote -n was not documented properly.

-GIT v1.5.2.4 Release Notes
-==========================
-
-Fixes since v1.5.2.3
---------------------
-
- * Bugfixes
-
- - "git-gui" bugfixes, including a handful fixes to run it
- better on Cygwin/MSYS.
-
- - "git checkout" failed to switch back and forth between
- branches, one of which has "frotz -> xyzzy" symlink and
- file "xyzzy/filfre", while the other one has a file
- "frotz/filfre".
-
- - "git prune" used to segfault upon seeing a commit that is
- referred to by a tree object (aka "subproject").
-
- - "git diff --name-status --no-index" mishandled an added file.
-
- - "git apply --reverse --whitespace=warn" still complained
- about whitespaces that a forward application would have
- introduced.
-
- * Documentation Fixes and Updates
-
- - A handful documentation updates.

-GIT v1.5.2.5 Release Notes
-==========================
-
-Fixes since v1.5.2.4
---------------------
-
- * Bugfixes
-
- - "git add -u" had a serious data corruption problem in one
- special case (when the changes to a subdirectory's files
- consist only deletion of files).
-
- - "git add -u <path>" did not work from a subdirectory.
-
- - "git apply" left an empty directory after all its files are
- renamed away.
-
- - "git $anycmd foo/bar", when there is a file 'foo' in the
- working tree, complained that "git $anycmd foo/bar --" form
- should be used to disambiguate between revs and files,
- which was completely bogus.
-
- - "git checkout-index" and other commands that checks out
- files to the work tree tried unlink(2) on directories,
- which is a sane thing to do on sane systems, but not on
- Solaris when you are root.
-
- * Documentation Fixes and Updates
-
- - A handful documentation fixes.

-GIT v1.5.2 Release Notes
-========================
-
-Updates since v1.5.1
---------------------
-
-* Plumbing level superproject support.
-
- You can include a subdirectory that has an independent git
- repository in your index and tree objects of your project
- ("superproject"). This plumbing (i.e. "core") level
- superproject support explicitly excludes recursive behaviour.
-
- The "subproject" entries in the index and trees of a superproject
- are incompatible with older versions of git. Experimenting with
- the plumbing level support is encouraged, but be warned that
- unless everybody in your project updates to this release or
- later, using this feature would make your project
- inaccessible by people with older versions of git.
-
-* Plumbing level gitattributes support.
-
- The gitattributes mechanism allows you to add 'attributes' to
- paths in your project, and affect the way certain git
- operations work. Currently you can influence if a path is
- considered a binary or text (the former would be treated by
- 'git diff' not to produce textual output; the latter can go
- through the line endings conversion process in repositories
- with core.autocrlf set), expand and unexpand '$Id$' keyword
- with blob object name, specify a custom 3-way merge driver,
- and specify a custom diff driver. You can also apply
- arbitrary filter to contents on check-in/check-out codepath
- but this feature is an extremely sharp-edged razor and needs
- to be handled with caution (do not use it unless you
- understand the earlier mailing list discussion on keyword
- expansion). These conversions apply when checking files in
- or out, and exporting via git-archive.
-
-* The packfile format now optionally supports 64-bit index.
-
- This release supports the "version 2" format of the .idx
- file. This is automatically enabled when a huge packfile
- needs more than 32-bit to express offsets of objects in the
- pack.
-
-* Comes with an updated git-gui 0.7.1
-
-* Updated gitweb:
-
- - can show combined diff for merges;
- - uses font size of user's preference, not hardcoded in pixels;
- - can now 'grep';
-
-* New commands and options.
-
- - "git bisect start" can optionally take a single bad commit and
- zero or more good commits on the command line.
-
- - "git shortlog" can optionally be told to wrap its output.
-
- - "subtree" merge strategy allows another project to be merged in as
- your subdirectory.
-
- - "git format-patch" learned a new --subject-prefix=<string>
- option, to override the built-in "[PATCH]".
-
- - "git add -u" is a quick way to do the first stage of "git
- commit -a" (i.e. update the index to match the working
- tree); it obviously does not make a commit.
-
- - "git clean" honors a new configuration, "clean.requireforce". When
- set to true, this makes "git clean" a no-op, preventing you
- from losing files by typing "git clean" when you meant to
- say "make clean". You can still say "git clean -f" to
- override this.
-
- - "git log" family of commands learned --date={local,relative,default}
- option. --date=relative is synonym to the --relative-date.
- --date=local gives the timestamp in local timezone.
-
-* Updated behavior of existing commands.
-
- - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
- but $EMAIL is set, the latter is used as a substitute.
-
- - "git diff --stat" shows size of preimage and postimage blobs
- for binary contents. Earlier it only said "Bin".
-
- - "git lost-found" shows stuff that are unreachable except
- from reflogs.
-
- - "git checkout branch^0" now detaches HEAD at the tip commit
- on the named branch, instead of just switching to the
- branch (use "git checkout branch" to switch to the branch,
- as before).
-
- - "git bisect next" can be used after giving only a bad commit
- without giving a good one (this starts bisection half-way to
- the root commit). We used to refuse to operate without a
- good and a bad commit.
-
- - "git push", when pushing into more than one repository, does
- not stop at the first error.
-
- - "git archive" does not insist you to give --format parameter
- anymore; it defaults to "tar".
-
- - "git cvsserver" can use backends other than sqlite.
-
- - "gitview" (in contrib/ section) learned to better support
- "git-annotate".
-
- - "git diff $commit1:$path2 $commit2:$path2" can now report
- mode changes between the two blobs.
-
- - Local "git fetch" from a repository whose object store is
- one of the alternates (e.g. fetching from the origin in a
- repository created with "git clone -l -s") avoids
- downloading objects unnecessarily.
-
- - "git blame" uses .mailmap to canonicalize the author name
- just like "git shortlog" does.
-
- - "git pack-objects" pays attention to pack.depth
- configuration variable.
-
- - "git cherry-pick" and "git revert" does not use .msg file in
- the working tree to prepare commit message; instead it uses
- $GIT_DIR/MERGE_MSG as other commands do.
-
-* Builds
-
- - git-p4import has never been installed; now there is an
- installation option to do so.
-
- - gitk and git-gui can be configured out.
-
- - Generated documentation pages automatically get version
- information from GIT_VERSION.
-
- - Parallel build with "make -j" descending into subdirectory
- was fixed.
-
-* Performance Tweaks
-
- - Optimized "git-rev-list --bisect" (hence "git-bisect").
-
- - Optimized "git-add $path" in a large directory, most of
- whose contents are ignored.
-
- - Optimized "git-diff-tree" for reduced memory footprint.
-
- - The recursive merge strategy updated a worktree file that
- was changed identically in two branches, when one of them
- renamed it. We do not do that when there is no rename, so
- match that behaviour. This avoids excessive rebuilds.
-
- - The default pack depth has been increased to 50, as the
- recent addition of delta_base_cache makes deeper delta chains
- much less expensive to access. Depending on the project, it was
- reported that this reduces the resulting pack file by 10%
- or so.
-
-
-Fixes since v1.5.1
-------------------
-
-All of the fixes in v1.5.1 maintenance series are included in
-this release, unless otherwise noted.
-
-* Bugfixes
-
- - Switching branches with "git checkout" refused to work when
- a path changes from a file to a directory between the
- current branch and the new branch, in order not to lose
- possible local changes in the directory that is being turned
- into a file with the switch. We now allow such a branch
- switch after making sure that there is no locally modified
- file nor un-ignored file in the directory. This has not
- been backported to 1.5.1.x series, as it is rather an
- intrusive change.
-
- - Merging branches that have a file in one and a directory in
- another at the same path used to get quite confused. We
- handle such a case a bit more carefully, even though that is
- still left as a conflict for the user to sort out. This
- will not be backported to 1.5.1.x series, as it is rather an
- intrusive change.
-
- - git-fetch had trouble with a remote with insanely large number
- of refs.
-
- - "git clean -d -X" now does not remove non-excluded directories.
-
- - rebasing (without -m) a series that changes a symlink to a directory
- in the middle of a path confused git-apply greatly and refused to
- operate.

-GIT v1.5.3.1 Release Notes
-==========================
-
-Fixes since v1.5.3
-------------------
-
-This is solely to fix the generated RPM's dependencies. We used

-the mailing list, this release makes git-core "Obsolete" git-p4,
-so that yum update would not complain.

-GIT v1.5.3.2 Release Notes
-==========================
-
-Fixes since v1.5.3.1
---------------------
-
- * git-push sent thin packs by default, which was not good for
- the public distribution server (no point in saving transfer
- while pushing; no point in making the resulting pack less
- optimum).
-
- * git-svn sometimes terminated with "Malformed network data" when
- talking over svn:// protocol.
-
- * git-send-email re-issued the same message-id about 10% of the
- time if you fired off 30 messages within a single second.
-
- * git-stash was not terminating the log message of commits it
- internally creates with LF.
-
- * git-apply failed to check the size of the patch hunk when its
- beginning part matched the remainder of the preimage exactly,
- even though the preimage recorded in the hunk was much larger
- (therefore the patch should not have applied), leading to a
- segfault.
-
- * "git rm foo && git commit foo" complained that 'foo' needs to
- be added first, instead of committing the removal, which was a
- nonsense.
-
- * git grep -c said "/dev/null: 0".
-
- * git-add -u failed to recognize a blob whose type changed
- between the index and the work tree.
-
- * The limit to rename detection has been tightened a lot to
- reduce performance problems with a huge change.
-
- * cvsimport and svnimport barfed when the input tried to move
- a tag.
-
- * "git apply -pN" did not chop the right number of directories.
-
- * "git svnimport" did not like SVN tags with funny characters in them.
-
- * git-gui 0.8.3, with assorted fixes, including:
-
- - font-chooser on X11 was unusable with large number of fonts;
- - a diff that contained a deleted symlink made it barf;
- - an untracked symbolic link to a directory made it fart;
- - a file with % in its name made it vomit;
-
-
-Documentation updates
----------------------
-
-User manual has been somewhat restructured. I think the new
-organization is much easier to read.

- partial commit of removal better had a segfaulting bug, which was
- diagnosed and fixed by Keith and Carl.
-
- * Performance improvements for rename detection has been backported
- from the 'master' branch.
-
- * "git-for-each-ref --format='%(numparent)'" was not working
- correctly at all, and --format='%(parent)' was not working for
- merge commits.
-
- * Sample "post-receive-hook" incorrectly sent out push
- notification e-mails marked as "From: " the committer of the
- commit that happened to be at the tip of the branch that was
- pushed, not from the person who pushed.
-
- * "git-remote" did not exit non-zero status upon error.
-
- * "git-add -i" did not respond very well to EOF from tty nor
- bogus input.

-
- * "git-blame" crashed if run during a merge conflict.
-
- * "git-add -i" did not handle single line hunks correctly.
-
- * "git-rebase -i" and "git-stash apply" failed if external diff
- drivers were used for one or more files in a commit. They now
- avoid calling the external diff drivers.
-
- * "git-log --follow" did not work unless diff generation (e.g. -p)
- was also requested.
-
- * "git-log --follow -B" did not work at all. Fixed.
-
- * "git-log -M -B" did not correctly handle cases of very large files

- not impact correctness, only user perception. The bogus error
- is no longer printed.
-
- * "git-ls-files --ignored" did not properly descend into non-ignored

-
- * Git segfaulted when reading an invalid .gitattributes file. Fixed.

- updates.
-

-
- * git-send-email added 8-bit contents to the payload without
- marking it as 8-bit in a CTE header.
-
- * "git-bundle create a.bndl HEAD" dereferenced the symref and
- did not record the ref as 'HEAD'; this prevented a bundle
- from being used as a normal source of git-clone.
-
- * The code to reject nonsense command line of the form
- "git-commit -a paths..." and "git-commit --interactive
- paths..." were broken.
-
- * Adding a signature that is not ASCII-only to an original
- commit that is ASCII-only would make the result non-ASCII.
- "git-format-patch -s" did not mark such a message correctly
- with MIME encoding header.
-
- * git-add sometimes did not mark the resulting index entry
- stat-clean. This affected only cases when adding the

-GIT v1.5.3 Release Notes
-========================
-
-Updates since v1.5.2
---------------------
-
-* The commit walkers other than http are officially deprecated,
- but still supported for now.
-
-* The submodule support has Porcelain layer.
-
- Note that the current submodule support is minimal and this is
- deliberately so. A design decision we made is that operations
- at the supermodule level do not recurse into submodules by
- default. The expectation is that later we would add a
- mechanism to tell git which submodules the user is interested
- in, and this information might be used to determine the
- recursive behaviour of certain commands (e.g. "git checkout"
- and "git diff"), but currently we haven't agreed on what that
- mechanism should look like. Therefore, if you use submodules,
- you would probably need "git submodule update" on the
- submodules you care about after running a "git checkout" at
- the supermodule level.
-
-* There are a handful pack-objects changes to help you cope better
- with repositories with pathologically large blobs in them.
-
-* For people who need to import from Perforce, a front-end for
- fast-import is in contrib/fast-import/.
-
-* Comes with git-gui 0.8.2.
-
-* Comes with updated gitk.
-
-* New commands and options.
-
- - "git log --date=<format>" can use more formats: iso8601, rfc2822.
-
- - The hunk header output from "git diff" family can be customized
- with the attributes mechanism. See gitattributes(5) for details.
-
- - "git stash" allows you to quickly save away your work in
- progress and replay it later on an updated state.
-
- - "git rebase" learned an "interactive" mode that let you
- pick and reorder which commits to rebuild.
-
- - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
- separate invocation of "git lost-found" command. The blobs stored by
- lost-found are stored in plain format to allow you to grep in them.
-
- - $GIT_WORK_TREE environment variable can be used together with
- $GIT_DIR to work in a subdirectory of a working tree that is
- not located at "$GIT_DIR/..".
-
- - Giving "--file=<file>" option to "git config" is the same as
- running the command with GIT_CONFIG=<file> environment.
-
- - "git log" learned a new option "--follow", to follow
- renaming history of a single file.
-
- - "git filter-branch" lets you rewrite the revision history of
- specified branches. You can specify a number of filters to
- modify the commits, files and trees.
-
- - "git cvsserver" learned new options (--base-path, --export-all,
- --strict-paths) inspired by "git daemon".
-
- - "git daemon --base-path-relaxed" can help migrating a repository URL
- that did not use to use --base-path to use --base-path.
-
- - "git commit" can use "-t templatefile" option and commit.template
- configuration variable to prime the commit message given to you in the
- editor.
-
- - "git submodule" command helps you manage the projects from
- the superproject that contain them.
-
- - In addition to core.compression configuration option,
- core.loosecompression and pack.compression options can
- independently tweak zlib compression levels used for loose
- and packed objects.
-
- - "git ls-tree -l" shows size of blobs pointed at by the
- tree entries, similar to "/bin/ls -l".
-
- - "git rev-list" learned --regexp-ignore-case and
- --extended-regexp options to tweak its matching logic used
- for --grep filtering.
-
- - "git describe --contains" is a handier way to call more
- obscure command "git name-rev --tags".
-
- - "git gc --aggressive" tells the command to spend more cycles
- to optimize the repository harder.
-
- - "git repack" learned a "window-memory" limit which
- dynamically reduces the window size to stay within the
- specified memory usage.
-
- - "git repack" can be told to split resulting packs to avoid
- exceeding limit specified with "--max-pack-size".
-
- - "git fsck" gained --verbose option. This is really really
- verbose but it might help you identify exact commit that is
- corrupt in your repository.
-
- - "git format-patch" learned --numbered-files option. This
- may be useful for MH users.
-
- - "git format-patch" learned format.subjectprefix configuration
- variable, which serves the same purpose as "--subject-prefix"
- option.
-
- - "git tag -n -l" shows tag annotations while listing tags.
-
- - "git cvsimport" can optionally use the separate-remote layout.
-
- - "git blame" can be told to see through commits that change
- whitespaces and indentation levels with "-w" option.
-
- - "git send-email" can be told not to thread the messages when
- sending out more than one patches.
-
- - "git send-email" can also be told how to find whom to cc the
- message to for each message via --cc-cmd.
-
- - "git config" learned NUL terminated output format via -z to
- help scripts.
-
- - "git add" learned "--refresh <paths>..." option to selectively refresh
- the cached stat information.
-
- - "git init -q" makes the command quieter.
-
- - "git -p command" now has a cousin of opposite sex, "git --no-pager
- command".
-
-* Updated behavior of existing commands.
-
- - "gitweb" can offer multiple snapshot formats.
-
- ***NOTE*** Unfortunately, this changes the format of the
- $feature{snapshot}{default} entry in the per-site
- configuration file 'gitweb_config.perl'. It used to be a
- three-element tuple that describe a single format; with the
- new configuration item format, you only have to say the name
- of the format ('tgz', 'tbz2' or 'zip'). Please update the
- your configuration file accordingly.
-
- - "git clone" uses -l (hardlink files under .git) by default when
- cloning locally.
-
- - URL used for "git clone" and friends can specify nonstandard SSH port
- by using ssh://host:port/path/to/repo syntax.
-
- - "git bundle create" can now create a bundle without negative refs,
- i.e. "everything since the beginning up to certain points".
-
- - "git diff" (but not the plumbing level "git diff-tree") now
- recursively descends into trees by default.
-
- - "git diff" does not show differences that come only from
- stat-dirtiness in the form of "diff --git" header anymore.
- It runs "update-index --refresh" silently as needed.
-
- - "git tag -l" used to match tags by globbing its parameter as if it
- has wildcard '*' on both ends, which made "git tag -l gui" to match
- tag 'gitgui-0.7.0'; this was very annoying. You now have to add
- asterisk on the sides you want to wildcard yourself.
-
- - The editor to use with many interactive commands can be
- overridden with GIT_EDITOR environment variable, or if it
- does not exist, with core.editor configuration variable. As
- before, if you have neither, environment variables VISUAL
- and EDITOR are consulted in this order, and then finally we
- fall back on "vi".
-
- - "git rm --cached" does not complain when removing a newly
- added file from the index anymore.
-
- - Options to "git log" to affect how --grep/--author options look for
- given strings now have shorter abbreviations. -i is for ignore case,
- and -E is for extended regexp.
-
- - "git log" learned --log-size to show the number of bytes in
- the log message part of the output to help qgit.
-
- - "git log --name-status" does not require you to give "-r" anymore.
- As a general rule, Porcelain commands should recurse when showing
- diff.
-
- - "git format-patch --root A" can be used to format everything
- since the beginning up to A. This was supported with
- "git format-patch --root A A" for a long time, but was not
- properly documented.
-
- - "git svn dcommit" retains local merge information.
-
- - "git svnimport" allows an empty string to be specified as the
- trunk/ directory. This is necessary to suck data from a SVN
- repository that doe not have trunk/ branches/ and tags/ organization
- at all.
-
- - "git config" to set values also honors type flags like --bool
- and --int.
-
- - core.quotepath configuration can be used to make textual git
- output to emit most of the characters in the path literally.
-
- - "git mergetool" chooses its backend more wisely, taking
- notice of its environment such as use of X, Gnome/KDE, etc.
-
- - "gitweb" shows merge commits a lot nicer than before. The
- default view uses more compact --cc format, while the UI
- allows to choose normal diff with any parent.
-
- - snapshot files "gitweb" creates from a repository at
- $path/$project/.git are more useful. We use $project part
- in the filename, which we used to discard.
-
- - "git cvsimport" creates lightweight tags; there is no
- interesting information we can record in an annotated tag,
- and the handcrafted ones the old code created was not
- properly formed anyway.
-
- - "git push" pretends that you immediately fetched back from
- the remote by updating corresponding remote tracking
- branches if you have any.
-
- - The diffstat given after a merge (or a pull) honors the
- color.diff configuration.
-
- - "git commit --amend" is now compatible with various message source
- options such as -m/-C/-c/-F.
-
- - "git apply --whitespace=strip" removes blank lines added at
- the end of the file.
-
- - "git fetch" over git native protocols with "-v" option shows
- connection status, and the IP address of the other end, to
- help diagnosing problems.
-
- - We used to have core.legacyheaders configuration, when
- set to false, allowed git to write loose objects in a format
- that mimics the format used by objects stored in packs. It
- turns out that this was not so useful. Although we will
- continue to read objects written in that format, we do not
- honor that configuration anymore and create loose objects in
- the legacy/traditional format.
-
- - "--find-copies-harder" option to diff family can now be
- spelled as "-C -C" for brevity.
-
- - "git mailsplit" (hence "git am") can read from Maildir
- formatted mailboxes.
-
- - "git cvsserver" does not barf upon seeing "cvs login"
- request.
-
- - "pack-objects" honors "delta" attribute set in
- .gitattributes. It does not attempt to deltify blobs that
- come from paths with delta attribute set to false.
-
- - "new-workdir" script (in contrib) can now be used with a
- bare repository.
-
- - "git mergetool" learned to use gvimdiff.
-
- - "gitview" (in contrib) has a better blame interface.
-
- - "git log" and friends did not handle a commit log message
- that is larger than 16kB; they do now.
-
- - "--pretty=oneline" output format for "git log" and friends
- deals with "malformed" commit log messages that have more
- than one lines in the first paragraph better. We used to
- show the first line, cutting the title at mid-sentence; we
- concatenate them into a single line and treat the result as
- "oneline".
-
- - "git p4import" has been demoted to contrib status. For
- a superior option, checkout the "git p4" front end to
- "git fast-import" (also in contrib). The man page and p4
- rpm have been removed as well.
-
- - "git mailinfo" (hence "am") now tries to see if the message
- is in utf-8 first, instead of assuming iso-8859-1, if
- incoming e-mail does not say what encoding it is in.
-
-* Builds
-
- - old-style function definitions (most notably, a function
- without parameter defined with "func()", not "func(void)")
- have been eradicated.
-
- - "git tag" and "git verify-tag" have been rewritten in C.
-
-* Performance Tweaks
-
- - "git pack-objects" avoids re-deltification cost by caching
- small enough delta results it creates while looking for the
- best delta candidates.
-
- - "git pack-objects" learned a new heuristic to prefer delta
- that is shallower in depth over the smallest delta
- possible. This improves both overall packfile access
- performance and packfile density.
-
- - diff-delta code that is used for packing has been improved
- to work better on big files.
-
- - when there are more than one pack files in the repository,
- the runtime used to try finding an object always from the
- newest packfile; it now tries the same packfile as we found
- the object requested the last time, which exploits the
- locality of references.
-
- - verifying pack contents done by "git fsck --full" got boost
- by carefully choosing the order to verify objects in them.
-
- - "git read-tree -m" to read into an already populated index
- has been optimized vastly. The effect of this can be seen
- when switching branches that have differences in only a
- handful paths.
-
- - "git add paths..." and "git commit paths..." has also been
- heavily optimized.
-
-Fixes since v1.5.2
-------------------
-
-All of the fixes in v1.5.2 maintenance series are included in
-this release, unless otherwise noted.
-
-* Bugfixes
-
- - "gitweb" had trouble handling non UTF-8 text with older
- Encode.pm Perl module.
-
- - "git svn" misparsed the data from the commits in the repository when
- the user had "color.diff = true" in the configuration. This has been
- fixed.
-
- - There was a case where "git svn dcommit" clobbered changes made on the
- SVN side while committing multiple changes.
-
- - "git-write-tree" had a bad interaction with racy-git avoidance and
- gitattributes mechanisms.
-
- - "git --bare command" overrode existing GIT_DIR setting and always
- made it treat the current working directory as GIT_DIR.
-
- - "git ls-files --error-unmatch" does not complain if you give the
- same path pattern twice by mistake.
-
- - "git init" autodetected core.filemode but not core.symlinks, which
- made a new directory created automatically by "git clone" cumbersome
- to use on filesystems that require these configurations to be set.
-
- - "git log" family of commands behaved differently when run as "git
- log" (no pathspec) and as "git log --" (again, no pathspec). This
- inconsistency was introduced somewhere in v1.3.0 series but now has
- been corrected.
-
- - "git rebase -m" incorrectly displayed commits that were skipped.

-GIT v1.5.4.1 Release Notes
-==========================
-
-Fixes since v1.5.4
-------------------
-
- * "git-commit -C $tag" used to work but rewrite in C done in
- 1.5.4 broke it.
-
- * An entry in the .gitattributes file that names a pattern in a
- subdirectory of the directory it is in did not match
- correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
- match "a/b/foo.c" but it didn't).
-
- * Customized color specification was parsed incorrectly when
- numeric color values are used. This was fixed in 1.5.4.1.
-
+++ /dev/null
-GIT v1.5.4.2 Release Notes
-==========================
-
-Fixes since v1.5.4
-------------------
-
- * The configuration parser was not prepared to see string
- valued variables misspelled as boolean and segfaulted.
-
- * Temporary files left behind due to interrupted object
- transfers were not cleaned up with "git prune".
-
- * "git config --unset" was confused when the unset variables
- were spelled with continuation lines in the config file.
-
- * The merge message detection in "git cvsimport" did not catch
- a message that began with "Merge...".
-
- * "git status" suggests "git rm --cached" for unstaging the
- earlier "git add" before the initial commit.
-
- * "git status" output was incorrect during a partial commit.
-
- * "git bisect" refused to start when the HEAD was detached.
-
- * "git bisect" allowed a wildcard character in the commit
- message expanded while writing its log file.
-
- * Manual pages were not formatted correctly with docbook xsl
- 1.72; added a workaround.
-
- * "git-commit -C $tag" used to work but rewrite in C done in
- 1.5.4 broke it. This was fixed in 1.5.4.1.
-
- * An entry in the .gitattributes file that names a pattern in a
- subdirectory of the directory it is in did not match
- correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
- match "a/b/foo.c" but it didn't). This was fixed in 1.5.4.1.
-
- * Customized color specification was parsed incorrectly when
- numeric color values are used. This was fixed in 1.5.4.1.
-
- * http transport misbehaved when linked with curl-gnutls.

-GIT v1.5.4.3 Release Notes
-==========================
-
-Fixes since v1.5.4.2
---------------------
-
- * RPM spec used to pull in everything with 'git'. This has been
- changed so that 'git' package contains just the core parts,
- and we now supply 'git-all' metapackage to slurp in everything.
- This should match end user's expectation better.
-
- * When some refs failed to update, git-push reported "failure"
- which was unclear if some other refs were updated or all of
- them failed atomically (the answer is the former). Reworded
- the message to clarify this.
-
- * "git clone" from a repository whose HEAD was misconfigured
- did not set up the remote properly. Now it tries to do
- better.
-
- * Updated git-push documentation to clarify what "matching"
- means, in order to reduce user confusion.
-
- * Updated git-add documentation to clarify "add -u" operates in
- the current subdirectory you are in, just like other commands.
-
- * git-gui updates to work on OSX and Windows better.

-GIT v1.5.4.4 Release Notes
-==========================
-
-Fixes since v1.5.4.3
---------------------
-
- * Building and installing with an overtight umask such as 077 made
- installed templates unreadable by others, while the rest of the install
- are done in a way that is friendly to umask 022.
-
- * "git cvsexportcommit -w $cvsdir" misbehaved when GIT_DIR is set to a
- relative directory.
-
- * "git http-push" had an invalid memory access that could lead it to
- segfault.
-
- * When "git rebase -i" gave control back to the user for a commit that is
- marked to be edited, it just said "modify it with commit --amend",
- without saying what to do to continue after modifying it. Give an
- explicit instruction to run "rebase --continue" to be more helpful.
-
- * "git send-email" in 1.5.4.3 issued a bogus empty In-Reply-To: header.
-
- * "git bisect" showed mysterious "won't bisect on seeked tree" error message.
- This was leftover from Cogito days to prevent "bisect" starting from a
- cg-seeked state. We still keep the Cogito safety, but running "git bisect
- start" when another bisect was in effect will clean up and start over.
-
- * "git push" with an explicit PATH to receive-pack did not quite work if
- receive-pack was not on usual PATH. We earlier fixed the same issue
- with "git fetch" and upload-pack, but somehow forgot to do so in the
- other direction.
-
- * git-gui's info dialog was not displayed correctly when the user tries
- to commit nothing (i.e. without staging anything).
-
- * "git revert" did not properly fail when attempting to run with a
- dirty index.
-
- * "git merge --no-commit --no-ff <other>" incorrectly made commits.
-
- * "git merge --squash --no-ff <other>", which is a nonsense combination
- of options, was not rejected.
-
- * "git ls-remote" and "git remote show" against an empty repository
- failed, instead of just giving an empty result (regression).
-
- * "git fast-import" did not handle a renamed path whose name needs to be
- quoted, due to a bug in unquote_c_style() function.
-
- * "git cvsexportcommit" was confused when multiple files with the same
- basename needed to be pushed out in the same commit.
-
- * "git daemon" did not send early errors to syslog.
-
- * "git log --merge" did not work well with --left-right option.
-
- * "git svn" prompted for client cert password every time it accessed the
- server.
-
- * The reset command in "git fast-import" data stream was documented to
- end with an optional LF, but it actually required one.
-
- * "git svn dcommit/rebase" did not honor --rewrite-root option.
-
-Also included are a handful documentation updates.
+++ /dev/null
-GIT v1.5.4.5 Release Notes
-==========================
-
-Fixes since v1.5.4.4
---------------------
-
- * "git fetch there" when the URL information came from the Cogito style
- branches/there file did not update refs/heads/there (regression in
- 1.5.4).
-
- * Bogus refspec configuration such as "remote.there.fetch = =" were not
- detected as errors (regression in 1.5.4).
-
- * You couldn't specify a custom editor whose path contains a whitespace
- via GIT_EDITOR (and core.editor).
-
- * The subdirectory filter to "git filter-branch" mishandled a history
- where the subdirectory becomes empty and then later becomes non-empty.
-
- * "git shortlog" gave an empty line if the original commit message was
- malformed (e.g. a botched import from foreign SCM). Now it finds the
- first non-empty line and uses it for better information.
-
- * When the user fails to give a revision parameter to "git svn", an error
- from the Perl interpreter was issued because the script lacked proper
- error checking.
-
- * After "git rebase" stopped due to conflicts, if the user played with
- "git reset" and friends, "git rebase --abort" failed to go back to the
- correct commit.
-
- * Additional work trees prepared with git-new-workdir (in contrib/) did
- not share git-svn metadata directory .git/svn with the original.
-
- * "git-merge-recursive" did not mark addition of the same path with
- different filemodes correctly as a conflict.
-
- * "gitweb" gave malformed URL when pathinfo stype paths are in use.
-
- * "-n" stands for "--no-tags" again for "git fetch".
-
- * "git format-patch" did not detect the need to add 8-bit MIME header
- when the user used format.header configuration.
-
- * "rev~" revision specifier used to mean "rev", which was inconsistent
- with how "rev^" worked. Now "rev~" is the same as "rev~1" (hence it
- also is the same as "rev^1"), and "rev~0" is the same as "rev^0"
- (i.e. it has to be a commit).
-
- * "git quiltimport" did not grok empty lines, lines in "file -pNNN"
- format to specify the prefix levels and lines with trailing comments.
-
- * "git rebase -m" triggered pre-commit verification, which made
- "rebase --continue" impossible.
-
-As usual, it also comes with many documentation fixes and clarifications.
+++ /dev/null
-GIT v1.5.4.6 Release Notes
-==========================
-
-I personally do not think there is any reason anybody should want to
-run v1.5.4.X series these days, because 'master' version is always
-more stable than any tagged released version of git.
-
-This is primarily to futureproof "git-shell" to accept requests
-without a dash between "git" and subcommand name (e.g. "git
-upload-pack") which the newer client will start to make sometime in
-the future.
-
-Fixes since v1.5.4.5
---------------------
-
- * Command line option "-n" to "git-repack" was not correctly parsed.
-
- * Error messages from "git-apply" when the patchfile cannot be opened
- have been improved.
-
- * Error messages from "git-bisect" when given nonsense revisions have
- been improved.
-
- * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
- stop parsing at the closing "}".
-
- * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
- but it should print nothing.
-
- * "git apply" did not enforce "match at the beginning" correctly.
-
- * a path specification "a/b" in .gitattributes file should not match
- "sub/a/b", but it did.
-
- * "git log --date-order --topo-order" did not override the earlier
- date-order with topo-order as expected.
-
- * "git fast-export" did not export octopus merges correctly.
-
- * "git archive --prefix=$path/" mishandled gitattributes.
-
-As usual, it also comes with many documentation fixes and clarifications.
-
+++ /dev/null
-GIT v1.5.4.7 Release Notes
-==========================
-
-Fixes since 1.5.4.7
--------------------
-
- * Removed support for an obsolete gitweb request URI, whose
- implementation ran "git diff" Porcelain, instead of using plumbing,
- which would have run an external diff command specified in the
- repository configuration as the gitweb user.
+++ /dev/null
-GIT v1.5.4 Release Notes
-========================
-
-Removal
--------
-
- * "git svnimport" was removed in favor of "git svn". It is still there
- in the source tree (contrib/examples) but unsupported.
-
- * As git-commit and git-status have been rewritten, "git runstatus"
- helper script lost all its users and has been removed.
-
-
-Temporarily disabled
---------------------
-
- * "git http-push" is known not to work well with cURL library older
- than 7.16, and we had reports of repository corruption. It is
- disabled on such platforms for now. Unfortunately, 1.5.3.8 shares
- the same issue. In other words, this does not mean you will be
- fine if you stick to an older git release. For now, please do not
- use http-push from older git with cURL older than 7.16 if you
- value your data. A proper fix will hopefully materialize in
- later versions.
-
-
-Deprecation notices
--------------------
-
- * From v1.6.0, git will by default install dashed form of commands
- (e.g. "git-commit") outside of users' normal $PATH, and will install
- only selected commands ("git" itself, and "gitk") in $PATH. This
- implies:
-
- - Using dashed forms of git commands (e.g. "git-commit") from the
- command line has been informally deprecated since early 2006, but
- now it officially is, and will be removed in the future. Use
- dash-less forms (e.g. "git commit") instead.
-
- - Using dashed forms from your scripts, without first prepending the
- return value from "git --exec-path" to the scripts' PATH, has been
- informally deprecated since early 2006, but now it officially is.
-
- - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
- PATH" early in your script is not deprecated with this change.
-
- Users are strongly encouraged to adjust their habits and scripts now
- to prepare for this change.
-
- * The post-receive hook was introduced in March 2007 to supersede
- the post-update hook, primarily to overcome the command line length
- limitation of the latter. Use of post-update hook will be deprecated
- in future versions of git, starting from v1.6.0.
-
- * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
- option, and will be removed in the future.
-
- * "git peek-remote" is deprecated, as "git ls-remote" was written in C
- and works for all transports; "git peek-remote" will be removed in
- the future.
-
- * "git repo-config" which was an old name for "git config" command
- has been supported without being advertised for a long time. The
- next feature release will remove it.
-
- * From v1.6.0, the repack.usedeltabaseoffset config option will default
- to true, which will give denser packfiles (i.e. more efficient storage).
- The downside is that git older than version 1.4.4 will not be able
- to directly use a repository packed using this setting.
-
- * From v1.6.0, the pack.indexversion config option will default to 2,
- which is slightly more efficient, and makes repacking more immune to
- data corruptions. Git older than version 1.5.2 may revert to version 1
- of the pack index with a manual "git index-pack" to be able to directly
- access corresponding pack files.
-
-
-Updates since v1.5.3
---------------------
-
- * Comes with much improved gitk, with i18n.
-
- * Comes with git-gui 0.9.2 with i18n.
-
- * gitk is now merged as a subdirectory of git.git project, in
- preparation for its i18n.
-
- * progress displays from many commands are a lot nicer to the eye.
- Transfer commands show throughput data.
-
- * many commands that pay attention to per-directory .gitignore now do
- so lazily, which makes the usual case go much faster.
-
- * Output processing for '--pretty=format:<user format>' has been
- optimized.
-
- * Rename detection of diff family while detecting exact matches has
- been greatly optimized.
-
- * Rename detection of diff family tries to make more natural looking
- pairing. Earlier, if multiple identical rename sources were
- found in the preimage, the source used was picked pretty much at random.
-
- * Value "true" for color.diff and color.status configuration used to
- mean "always" (even when the output is not going to a terminal).
- This has been corrected to mean the same thing as "auto".
-
- * "git diff" Porcelain now respects diff.external configuration, which
- is another way to specify GIT_EXTERNAL_DIFF.
-
- * "git diff" can be told to use different prefixes other than
- "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
-
- * "git diff" sometimes did not quote paths with funny
- characters properly.
-
- * "git log" (and any revision traversal commands) misbehaved
- when --diff-filter is given but was not asked to actually
- produce diff.
-
- * HTTP proxy can be specified per remote repository using
- remote.*.httpproxy configuration, or global http.proxy configuration
- variable.
-
- * Various Perforce importer updates.
-
- * Example update and post-receive hooks have been improved.
-
- * Any command that wants to take a commit object name can now use
- ":/string" syntax to name a commit.
-
- * "git reset" is now built-in and its output can be squelched with -q.
-
- * "git reset --hard" does not make any sense in a bare
- repository, but did not error out; fixed.
-
- * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
-
- * "git rebase" learned --whitespace option.
-
- * In "git rebase", when you decide not to replay a particular change
- after the command stopped with a conflict, you can say "git rebase
- --skip" without first running "git reset --hard", as the command now
- runs it for you.
-
- * "git rebase --interactive" mode can now work on detached HEAD.
-
- * Other minor to serious bugs in "git rebase -i" have been fixed.
-
- * "git rebase" now detaches head during its operation, so after a
- successful "git rebase" operation, the reflog entry branch@{1} for
- the current branch points at the commit before the rebase was
- started.
-
- * "git rebase -i" also triggers rerere to help your repeated merges.
-
- * "git merge" can call the "post-merge" hook.
-
- * "git pack-objects" can optionally run deltification with multiple
- threads.
-
- * "git archive" can optionally substitute keywords in files marked with
- export-subst attribute.
-
- * "git cherry-pick" made a misguided attempt to repeat the original
- command line in the generated log message, when told to cherry-pick a
- commit by naming a tag that points at it. It does not anymore.
-
- * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the
- various date fields in different formats.
-
- * "git gc --auto" is a low-impact way to automatically run a variant of
- "git repack" that does not lose unreferenced objects (read: safer
- than the usual one) after the user accumulates too many loose
- objects.
-
- * "git clean" has been rewritten in C.
-
- * You need to explicitly set clean.requireForce to "false" to allow
- "git clean" without -f to do any damage (lack of the configuration
- variable used to mean "do not require -f option to lose untracked
- files", but we now use the safer default).
-
- * The kinds of whitespace errors "git diff" and "git apply" notice (and
- fix) can be controlled via 'core.whitespace' configuration variable
- and 'whitespace' attribute in .gitattributes file.
-
- * "git push" learned --dry-run option to show what would happen if a
- push is run.
-
- * "git push" does not update a tracking ref on the local side when the
- remote refused to update the corresponding ref.
-
- * "git push" learned --mirror option. This is to push the local refs
- one-to-one to the remote, and deletes refs from the remote that do
- not exist anymore in the repository on the pushing side.
-
- * "git push" can remove a corrupt ref at the remote site with the usual
- ":ref" refspec.
-
- * "git remote" knows --mirror mode. This is to set up configuration to
- push into a remote repository to store local branch heads to the same
- branch on the remote side, and remove branch heads locally removed
- from local repository at the same time. Suitable for pushing into a
- back-up repository.
-
- * "git remote" learned "rm" subcommand.
-
- * "git cvsserver" can be run via "git shell". Also, "cvs" is
- recognized as a synonym for "git cvsserver", so that CVS users
- can be switched to git just by changing their login shell.
-
- * "git cvsserver" acts more like receive-pack by running post-receive
- and post-update hooks.
-
- * "git am" and "git rebase" are far less verbose.
-
- * "git pull" learned to pass --[no-]ff option to underlying "git
- merge".
-
- * "git pull --rebase" is a different way to integrate what you fetched
- into your current branch.
-
- * "git fast-export" produces data-stream that can be fed to fast-import
- to reproduce the history recorded in a git repository.
-
- * "git add -i" takes pathspecs to limit the set of files to work on.
-
- * "git add -p" is a short-hand to go directly to the selective patch
- subcommand in the interactive command loop and to exit when done.
-
- * "git add -i" UI has been colorized. The interactive prompt
- and menu can be colored by setting color.interactive
- configuration. The diff output (including the hunk picker)
- are colored with color.diff configuration.
-
- * "git commit --allow-empty" allows you to create a single-parent
- commit that records the same tree as its parent, overriding the usual
- safety valve.
-
- * "git commit --amend" can amend a merge that does not change the tree
- from its first parent.
-
- * "git commit" used to unconditionally strip comment lines that
- began with '#' and removed excess blank lines. This behavior has
- been made configurable.
-
- * "git commit" has been rewritten in C.
-
- * "git stash random-text" does not create a new stash anymore. It was
- a UI mistake. Use "git stash save random-text", or "git stash"
- (without extra args) for that.
-
- * "git stash clear extra-text" does not clear the whole stash
- anymore. It is tempting to expect "git stash clear stash@{2}"
- to drop only a single named stash entry, and it is rude to
- discard everything when that is asked (but not provided).
-
- * "git prune --expire <time>" can exempt young loose objects from
- getting pruned.
-
- * "git branch --contains <commit>" can list branches that are
- descendants of a given commit.
-
- * "git log" learned --early-output option to help interactive GUI
- implementations.
-
- * "git bisect" learned "skip" action to mark untestable commits.
-
- * "git bisect visualize" learned a shorter synonym "git bisect view".
-
- * "git bisect visualize" runs "git log" in a non-windowed
- environments. It also can be told what command to run (e.g. "git
- bisect visualize tig").
-
- * "git format-patch" learned "format.numbered" configuration variable
- to automatically turn --numbered option on when more than one commits
- are formatted.
-
- * "git ls-files" learned "--exclude-standard" to use the canned set of
- exclude files.
-
- * "git tag -a -f existing" begins the editor session using the existing
- annotation message.
-
- * "git tag -m one -m bar" (multiple -m options) behaves similarly to
- "git commit"; the parameters to -m options are formatted as separate
- paragraphs.
-
- * The format "git show" outputs an annotated tag has been updated to
- include "Tagger: " and "Date: " lines from the tag itself. Strictly
- speaking this is a backward incompatible change, but this is a
- reasonable usability fix and people's scripts shouldn't have been
- relying on the exact output from "git show" Porcelain anyway.
-
- * "git cvsimport" did not notice errors from underlying "cvsps"
- and produced a corrupt import silently.
-
- * "git cvsexportcommit" learned -w option to specify and switch to the
- CVS working directory.
-
- * "git checkout" from a subdirectory learned to use "../path" to allow
- checking out a path outside the current directory without cd'ing up.
-
- * "git checkout" from and to detached HEAD leaves a bit more
- information in the reflog.
-
- * "git send-email --dry-run" shows full headers for easier diagnosis.
-
- * "git merge-ours" is now built-in.
-
- * "git svn" learned "info" and "show-externals" subcommands.
-
- * "git svn" run from a subdirectory failed to read settings from the
- .git/config.
-
- * "git svn" learned --use-log-author option, which picks up more
- descriptive name from From: and Signed-off-by: lines in the commit
- message.
-
- * "git svn" wasted way too much disk to record revision mappings
- between svn and git; a new representation that is much more compact
- for this information has been introduced to correct this.
-
- * "git svn" left temporary index files it used without cleaning them
- up; this was corrected.
-
- * "git status" from a subdirectory now shows relative paths, which
- makes copy-and-pasting for git-checkout/git-add/git-rm easier. The
- traditional behavior to show the full path relative to the top of
- the work tree can be had by setting status.relativepaths
- configuration variable to false.
-
- * "git blame" kept text for each annotated revision in core needlessly;
- this has been corrected.
-
- * "git shortlog" learned to default to HEAD when the standard input is
- a terminal and the user did not give any revision parameter.
-
- * "git shortlog" learned "-e" option to show e-mail addresses as well as
- authors' names.
-
- * "git help" learned "-w" option to show documentation in browsers.
-
- * In addition there are quite a few internal clean-ups. Notably:
-
- - many fork/exec have been replaced with run-command API,
- brought from the msysgit effort.
-
- - introduction and more use of the option parser API.
-
- - enhancement and more use of the strbuf API.
-
- * Makefile tweaks to support HP-UX is in.
-
-Fixes since v1.5.3
-------------------
-
-All of the fixes in v1.5.3 maintenance series are included in
-this release, unless otherwise noted.
-
-These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
-series.
-
- * The way "git diff --check" behaves is much more consistent with the way
- "git apply --whitespace=warn" works.
-
- * "git svn" talking with the SVN over HTTP will correctly quote branch
- and project names.
-
- * "git config" did not work correctly on platforms that define
- REG_NOMATCH to an even number.
-
- * Recent versions of AsciiDoc 8 has a change to break our
- documentation; a workaround has been implemented.
-
- * "git diff --color-words" colored context lines in a wrong color.

-GIT v1.5.5.1 Release Notes
-==========================
-
-Fixes since v1.5.5
-------------------
-
- * "git archive --prefix=$path/" mishandled gitattributes.
-
- * "git fetch -v" that fetches into FETCH_HEAD did not report the summary
- the same way as done for updating the tracking refs.
-
- * "git svn" misbehaved when the configuration file customized the "git
- log" output format using format.pretty.
-
- * "git submodule status" leaked an unnecessary error message.
-
- * "git log --date-order --topo-order" did not override the earlier
- date-order with topo-order as expected.
-
- * "git bisect good $this" did not check the validity of the revision
- given properly.
-
- * "url.<there>.insteadOf" did not work correctly.
-
- * "git clean" ran inside subdirectory behaved as if the directory was
- explicitly specified for removal by the end user from the top level.
-
- * "git bisect" from a detached head leaked an unnecessary error message.
-
- * "git bisect good $a $b" when $a is Ok but $b is bogus should have
- atomically failed before marking $a as good.
-
- * "git fmt-merge-msg" did not clean up leading empty lines from commit
- log messages like "git log" family does.
-
- * "git am" recorded a commit with empty Subject: line without
- complaining.
-
- * when given a commit log message whose first paragraph consists of
- multiple lines, "git rebase" squashed it into a single line.
-
- * "git remote add $bogus_name $url" did not complain properly.
-
-Also comes with various documentation updates.

-
-Fixes since v1.5.5.1
---------------------
-
- * "git repack -n" was mistakenly made no-op earlier.
-
- * "git imap-send" wanted to always have imap.host even when use of
- imap.tunnel made it unnecessary.
-
- * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
- stop parsing at the closing "}".
-
- * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
- but it should print nothing.
-
- * "git commit" did not detect when it failed to write tree objects.
-
- * "git fetch" sometimes transferred too many objects unnecessarily.
-
- * a path specification "a/b" in .gitattributes file should not match
- "sub/a/b".

-GIT v1.5.5.5 Release Notes
-==========================
-
-I personally do not think there is any reason anybody should want to
-run v1.5.5.X series these days, because 'master' version is always
-more stable than any tagged released version of git.
-
-This is primarily to futureproof "git-shell" to accept requests
-without a dash between "git" and subcommand name (e.g. "git
-upload-pack") which the newer client will start to make sometime in
-the future.

- which would have run an external diff command specified in the
- repository configuration as the gitweb user.

-GIT v1.5.5 Release Notes
-========================
-
-Updates since v1.5.4
---------------------
-
-(subsystems)
-
- * Comes with git-gui 0.10.1
-
-(portability)
-
- * We shouldn't ask for BSD group ownership semantics by setting g+s bit
- on directories on older BSD systems that refuses chmod() by non root
- users. BSD semantics is the default there anyway.
-
- * Bunch of portability improvement patches coming from an effort to port
- to Solaris has been applied.
-
-(performance)
-
- * On platforms with suboptimal qsort(3) implementation, there
- is an option to use more reasonable substitute we ship with
- our software.
-
- * New configuration variable "pack.packsizelimit" can be used
- in place of command line option --max-pack-size.
-
- * "git fetch" over the native git protocol used to make a
- connection to find out the set of current remote refs and
- another to actually download the pack data. We now use only
- one connection for these tasks.
-
- * "git commit" does not run lstat(2) more than necessary
- anymore.
-
-(usability, bells and whistles)
-
- * Bash completion script (in contrib) are aware of more commands and
- options.
-
- * You can be warned when core.autocrlf conversion is applied in
- such a way that results in an irreversible conversion.
-
- * A catch-all "color.ui" configuration variable can be used to
- enable coloring of all color-capable commands, instead of
- individual ones such as "color.status" and "color.branch".
-
- * The commands refused to take absolute pathnames where they
- require pathnames relative to the work tree or the current
- subdirectory. They now can take absolute pathnames in such a
- case as long as the pathnames do not refer outside of the
- work tree. E.g. "git add $(pwd)/foo" now works.
-
- * Error messages used to be sent to stderr, only to get hidden,
- when $PAGER was in use. They now are sent to stdout along
- with the command output to be shown in the $PAGER.
-
- * A pattern "foo/" in .gitignore file now matches a directory
- "foo". Pattern "foo" also matches as before.
-
- * bash completion's prompt helper function can talk about
- operation in-progress (e.g. merge, rebase, etc.).
-
- * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
- used to tell "git-fetch" and "git-push" to use different URL than what
- is given from the command line.
-
- * "git add -i" behaves better even before you make an initial commit.
-
- * "git am" refused to run from a subdirectory without a good reason.
-
- * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
- a line before the fix can appear as a context or preimage line in a
- later patch, causing the patch not to apply. The command now knows to
- see through whitespace fixes done to context lines to successfully
- apply such a patch series.
-
- * "git branch" (and "git checkout -b") to branch from a local branch can
- optionally set "branch.<name>.merge" to mark the new branch to build on
- the other local branch, when "branch.autosetupmerge" is set to
- "always", or when passing the command line option "--track" (this option
- was ignored when branching from local branches). By default, this does
- not happen when branching from a local branch.
-
- * "git checkout" to switch to a branch that has "branch.<name>.merge" set
- (i.e. marked to build on another branch) reports how much the branch
- and the other branch diverged.
-
- * When "git checkout" has to update a lot of paths, it used to be silent
- for 4 seconds before it showed any progress report. It is now a bit
- more impatient and starts showing progress report early.
-
- * "git commit" learned a new hook "prepare-commit-msg" that can
- inspect what is going to be committed and prepare the commit
- log message template to be edited.
-
- * "git cvsimport" can now take more than one -M options.
-
- * "git describe" learned to limit the tags to be used for
- naming with --match option.
-
- * "git describe --contains" now barfs when the named commit
- cannot be described.
-
- * "git describe --exact-match" describes only commits that are tagged.
-
- * "git describe --long" describes a tagged commit as $tag-0-$sha1,
- instead of just showing the exact tagname.
-
- * "git describe" warns when using a tag whose name and path contradict
- with each other.
-
- * "git diff" learned "--relative" option to limit and output paths
- relative to the current directory when working in a subdirectory.
-
- * "git diff" learned "--dirstat" option to show birds-eye-summary of
- changes more concisely than "--diffstat".
-
- * "git format-patch" learned --cover-letter option to generate a cover
- letter template.
-
- * "git gc" learned --quiet option.
-
- * "git gc" now automatically prunes unreachable objects that are two
- weeks old or older.
-
- * "git gc --auto" can be disabled more easily by just setting gc.auto
- to zero. It also tolerates more packfiles by default.
-
- * "git grep" now knows "--name-only" is a synonym for the "-l" option.
-
- * "git help <alias>" now reports "'git <alias>' is alias to <what>",
- instead of saying "No manual entry for git-<alias>".
-
- * "git help" can use different backends to show manual pages and this can
- be configured using "man.viewer" configuration.
-
- * "gitk" does not restore window position from $HOME/.gitk anymore (it
- still restores the size).
-
- * "git log --grep=<what>" learned "--fixed-strings" option to look for
- <what> without treating it as a regular expression.
-
- * "git gui" learned an auto-spell checking.
-
- * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
- expected; they push the current branch (and only the current branch).
- In addition, HEAD can be written as the value of "remote.<there>.push"
- configuration variable.
-
- * When the configuration variable "pack.threads" is set to 0, "git
- repack" auto detects the number of CPUs and uses that many threads.
-
- * "git send-email" learned to prompt for passwords
- interactively.
-
- * "git send-email" learned an easier way to suppress CC
- recipients.
-
- * "git stash" learned "pop" command, that applies the latest stash and
- removes it from the stash, and "drop" command to discard the named
- stash entry.
-
- * "git submodule" learned a new subcommand "summary" to show the
- symmetric difference between the HEAD version and the work tree version
- of the submodule commits.
-
- * Various "git cvsimport", "git cvsexportcommit", "git cvsserver",
- "git svn" and "git p4" improvements.
-
-(internal)
-
- * Duplicated code between git-help and git-instaweb that
- launches user's preferred browser has been refactored.
-
- * It is now easier to write test scripts that records known
- breakages.
-
- * "git checkout" is rewritten in C.
-
- * "git remote" is rewritten in C.
-
- * Two conflict hunks that are separated by a very short span of common
- lines are now coalesced into one larger hunk, to make the result easier
- to read.
-
- * Run-command API's use of file descriptors is documented clearer and
- is more consistent now.
-
- * diff output can be sent to FILE * that is different from stdout. This
- will help reimplementing more things in C.
-
-Fixes since v1.5.4
-------------------
-
-All of the fixes in v1.5.4 maintenance series are included in
-this release, unless otherwise noted.
-
- * "git-http-push" did not allow deletion of remote ref with the usual
- "push <remote> :<branch>" syntax.
-
- * "git-rebase --abort" did not go back to the right location if
- "git-reset" was run during the "git-rebase" session.
-
- * "git imap-send" without setting imap.host did not error out but
- segfaulted.

-GIT v1.5.6.1 Release Notes
-==========================
-
-Fixes since v1.5.6
-------------------
-
-* Last minute change broke loose object creation on AIX.
-
-* (performance fix) We used to make $GIT_DIR absolute path early in the
- programs but keeping it relative to the current directory internally
- gives 1-3 per-cent performance boost.
-
-* bash completion knows the new --graph option to git-log family.
-
-
-* git-diff -c/--cc showed unnecessary "deletion" lines at the context
- boundary.
-
-* git-for-each-ref ignored %(object) and %(type) requests for tag
- objects.
-
-* git-merge usage had a typo.
-
-* Rebuilding of git-svn metainfo database did not take rewriteRoot
- option into account.
-
-* Running "git-rebase --continue/--skip/--abort" before starting a
- rebase gave nonsense error messages.
+++ /dev/null
-GIT v1.5.6.2 Release Notes
-==========================
-
-Futureproof
------------
-
- * "git-shell" accepts requests without a dash between "git" and
- subcommand name (e.g. "git upload-pack") which the newer client will
- start to make sometime in the future.
-
-Fixes since v1.5.6.1
---------------------
-
-* "git clone" from a remote that is named with url.insteadOf setting in
- $HOME/.gitconfig did not work well.
-
-* "git describe --long --tags" segfaulted when the described revision was
- tagged with a lightweight tag.
-
-* "git diff --check" did not report the result via its exit status
- reliably.
-
-* When remote side used to have branch 'foo' and git-fetch finds that now
- it has branch 'foo/bar', it refuses to lose the existing remote tracking
- branch and its reflog. The error message has been improved to suggest
- pruning the remote if the user wants to proceed and get the latest set
- of branches from the remote, including such 'foo/bar'.
-
-* "git reset file" should mean the same thing as "git reset HEAD file",
- but we required disambiguating -- even when "file" is not ambiguous.
-
-* "git show" segfaulted when an annotated tag that points at another
- annotated tag was given to it.
-
-* Optimization for a large import via "git-svn" introduced in v1.5.6 had a
- serious memory and temporary file leak, which made it unusable for
- moderately large import.
-
-* "git-svn" mangled remote nickname used in the configuration file
- unnecessarily.
+++ /dev/null
-GIT v1.5.6.3 Release Notes
-==========================
-
-Fixes since v1.5.6.2
---------------------
-
-* Setting core.sharedrepository to traditional "true" value was supposed to make
- the repository group writable but should not affect permission for others.
- However, since 1.5.6, it was broken to drop permission for others when umask is
- 022, making the repository unreadable by others.
-
-* Setting GIT_TRACE will report spawning of external process via run_command().
-
-* Using an object with very deep delta chain pinned memory needed for extracting
- intermediate base objects unnecessarily long, leading to excess memory usage.
-
-* Bash completion script did not notice '--' marker on the command
- line and tried the relatively slow "ref completion" even when
- completing arguments after one.
-
-* Registering a non-empty blob racily and then truncating the working
- tree file for it confused "racy-git avoidance" logic into thinking
- that the path is now unchanged.
-
-* The section that describes attributes related to git-archive were placed
- in a wrong place in the gitattributes(5) manual page.
-
-* "git am" was not helpful to the users when it detected that the committer
- information is not set up properly yet.
-
-* "git clone" had a leftover debugging fprintf().
-
-* "git clone -q" was not quiet enough as it used to and gave object count
- and progress reports.
-
-* "git clone" marked downloaded packfile with .keep; this could be a
- good thing if the remote side is well packed but otherwise not,
- especially for a project that is not really big.
-
-* "git daemon" used to call syslog() from a signal handler, which
- could raise signals of its own but generally is not reentrant. This
- was fixed by restructuring the code to report syslog() after the handler
- returns.
-
-* When "git push" tries to remove a remote ref, and corresponding
- tracking ref is missing, we used to report error (i.e. failure to
- remove something that does not exist).
-
-* "git mailinfo" (hence "git am") did not handle commit log messages in a
- MIME multipart mail correctly.
-
-Contains other various documentation fixes.

-GIT v1.5.6.4 Release Notes
-==========================
-
-Fixes since v1.5.6.3
---------------------
-
-* Various commands could overflow its internal buffer on a platform
- with small PATH_MAX value in a repository that has contents with
- long pathnames.
-
-* There wasn't a way to make --pretty=format:%<> specifiers to honor
- .mailmap name rewriting for authors and committers. Now you can with
- %aN and %cN.
-
-* Bash completion wasted too many cycles; this has been optimized to be
- usable again.
-
-* Bash completion lost ref part when completing something like "git show
- pu:Makefile".
-
-* "git-cvsserver" did not clean up its temporary working area after annotate
- request.
-
-* "git-daemon" called syslog() from its signal handler, which was a
- no-no.
-
-* "git-fetch" into an empty repository used to remind that the fetch will
- be huge by saying "no common commits", but this was an unnecessary
- noise; it is already known by the user anyway.
-
-* "git-http-fetch" would have segfaulted when pack idx file retrieved
- from the other side was corrupt.
-
-* "git-index-pack" used too much memory when dealing with a deep delta chain.
-
-* "git-mailinfo" (hence "git-am") did not correctly handle in-body [PATCH]
- line to override the commit title taken from the mail Subject header.
-
-* "git-rebase -i -p" lost parents that are not involved in the history
- being rewritten.
-
-* "git-rm" lost track of where the index file was when GIT_DIR was
- specified as a relative path.
-
-* "git-rev-list --quiet" was not quiet as advertised.

-* "git commit -F filename" and "git tag -F filename" run from subdirectories
- did not read the right file.
-
-* "git init --template=" with blank "template" parameter linked files
- under root directories to .git, which was a total nonsense. Instead, it

-Updates since v1.5.5
---------------------
-
-(subsystems)
-
-* Comes with updated gitk and git-gui.
-
-(portability)
-
-* git will build on AIX better than before now.
-
-* core.ignorecase configuration variable can be used to work better on
- filesystems that are not case sensitive.
-
-* "git init" now autodetects the case sensitivity of the filesystem and
- sets core.ignorecase accordingly.
-
-* cpio is no longer used; neither "curl" binary (libcurl is still used).
-
-(documentation)
-
-* Many freestanding documentation pages have been converted and made
- available to "git help" (aka "man git<something>") as section 7 of
- the manual pages. This means bookmarks to some HTML documentation
- files may need to be updated (eg "tutorial.html" became
- "gittutorial.html").

-* "git rebase --onto $there $from $branch" used to switch to the tip of
- $branch only to immediately reset back to $from, smudging work tree
- files unnecessarily. This has been optimized.
-
-* Object creation codepath in "git-svn" has been optimized by enhancing
- plumbing commands git-cat-file and git-hash-object.
-
-(usability, bells and whistles)
-
-* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
- apply (or not apply) mode changes independently from contents changes.
-
-* "git bisect help" gives longer and more helpful usage information.
-
-* "git bisect" does not use a special branch "bisect" anymore; instead, it
- does its work on a detached HEAD.
-
-* "git branch" (and "git checkout -b") can be told to set up
- branch.<name>.rebase automatically, so that later you can say "git pull"
- and magically cause "git pull --rebase" to happen.
-
-* "git branch --merged" and "git branch --no-merged" can be used to list
- branches that have already been merged (or not yet merged) to the
- current branch.
-
-* "git cherry-pick" and "git revert" can add a sign-off.
-
-* "git commit" mentions the author identity when you are committing
- somebody else's changes.
-
-* "git diff/log --dirstat" output is consistent between binary and textual
- changes.
-
-* "git filter-branch" rewrites signed tags by demoting them to annotated.
-
-* "git format-patch --no-binary" can produce a patch that lack binary
- changes (i.e. cannot be used to propagate the whole changes) meant only
- for reviewing.
-
-* "git init --bare" is a synonym for "git --bare init" now.
-
-* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
-
-* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
- instead of giving a LF between each pair of entries which is how
- "git log --pretty=format:<custom format>" works.
-
-* "git log" and friends learned the "--graph" option to show the ancestry
- graph at the left margin of the output.
-
-* "git log" and friends can be told to use date format that is different
- from the default via 'log.date' configuration variable.
-
-* "git send-email" now can send out messages outside a git repository.
-
-* "git send-email --compose" was made aware of rfc2047 quoting.
-
-* "git status" can optionally include output from "git submodule
- summary".
-
-* "git svn" learned --add-author-from option to propagate the authorship
- by munging the commit log message.
-
-* new object creation and looking up in "git svn" has been optimized.
-
-* "gitweb" can read from a system-wide configuration file.
-
-(internal)
-
-* "git unpack-objects" and "git receive-pack" is now more strict about
- detecting breakage in the objects they receive over the wire.
-
-
-Fixes since v1.5.5
-------------------
-
-All of the fixes in v1.5.5 maintenance series are included in
-this release, unless otherwise noted.
-
-And there are too numerous small fixes to otherwise note here ;-)

-GIT v1.6.0.1 Release Notes
-==========================
-
-Fixes since v1.6.0
-------------------
-
-* "git diff --cc" did not honor content mangling specified by
- gitattributes and core.autocrlf when reading from the work tree.
-
-* "git diff --check" incorrectly detected new trailing blank lines when
- whitespace check was in effect.
-
-* "git for-each-ref" tried to dereference NULL when asked for '%(body)" on
- a tag with a single incomplete line as its payload.
-
-* "git format-patch" peeked before the beginning of a string when
- "format.headers" variable is empty (a misconfiguration).
-
-* "git help help" did not work correctly.
-
-* "git mailinfo" (hence "git am") was unhappy when MIME multipart message
- contained garbage after the finishing boundary.
-
-* "git mailinfo" also was unhappy when the "From: " line only had a bare
- e-mail address.
-
-* "git merge" did not refresh the index correctly when a merge resulted in
- a fast-forward.
-
-* "git merge" did not resolve a truly trivial merges that can be done
- without content level merges.
-
-* "git svn dcommit" to a repository with URL that has embedded usernames

-GIT v1.6.0.2 Release Notes
-==========================
-
-Fixes since v1.6.0.1
---------------------
-
-* Installation on platforms that needs .exe suffix to git-* programs were
- broken in 1.6.0.1.
-
-* Installation on filesystems without symbolic links support did not
- work well.
-
-* In-tree documentations and test scripts now use "git foo" form to set a
- better example, instead of the "git-foo" form (which is an acceptable
- form if you have "PATH=$(git --exec-path):$PATH" in your script)
-
-* Many commands did not use the correct working tree location when used
- with GIT_WORK_TREE environment settings.
-
-* Some systems need to use compatibility fnmatch and regex libraries
- independent from each other; the compat/ area has been reorganized to
- allow this.
-
-
-* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
- a new line before the second line.
-
-* "git blame -c" did not exactly work like "git annotate" when range
- boundaries are involved.
-
-* "git checkout file" when file is still unmerged checked out contents from
- a random high order stage, which was confusing.
-
-* "git clone $there $here/" with extra trailing slashes after explicit
- local directory name $here did not work as expected.
-
-* "git diff" on tracked contents with CRLF line endings did not drive "less"
- intelligently when showing added or removed lines.
-
-* "git diff --dirstat -M" did not add changes in subdirectories up
- correctly for renamed paths.
-
-* "git diff --cumulative" did not imply "--dirstat".
-
-* "git for-each-ref refs/heads/" did not work as expected.
-
-* "git gui" allowed users to feed patch without any context to be applied.
-
-* "git gui" botched parsing "diff" output when a line that begins with two
- dashes and a space gets removed or a line that begins with two pluses
- and a space gets added.
-
-* "git gui" translation updates and i18n fixes.
-
-* "git index-pack" is more careful against disk corruption while completing
- a thin pack.
-
-* "git log -i --grep=pattern" did not ignore case; neither "git log -E
- --grep=pattern" triggered extended regexp.
-
-* "git log --pretty="%ad" --date=short" did not use short format when
- showing the timestamp.
-
-* "git log --author=author" match incorrectly matched with the
- timestamp part of "author " line in commit objects.
-
-* "git log -F --author=author" did not work at all.
-
-* Build procedure for "git shell" that used stub versions of some
- functions and globals was not understood by linkers on some platforms.
-
-* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
- and refused to work until the user refreshed the index.
-
-* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
- use of temporary files.
-
-* "git verify-pack -v" did not work correctly when given more than one
- packfile.
-
-Also contains many documentation updates.

-GIT v1.6.0.3 Release Notes
-==========================
-
-Fixes since v1.6.0.2
---------------------
-
-* "git archive --format=zip" did not honor core.autocrlf while
- --format=tar did.
-
-* Continuing "git rebase -i" was very confused when the user left modified
- files in the working tree while resolving conflicts.
-
-* Continuing "git rebase -i" was also very confused when the user left
- some staged changes in the index after "edit".
-
-* "git rebase -i" now honors the pre-rebase hook, just like the
- other rebase implementations "git rebase" and "git rebase -m".
-
-* "git rebase -i" incorrectly aborted when there is no commit to replay.
-
-* Behaviour of "git diff --quiet" was inconsistent with "diff --exit-code"
- with the output redirected to /dev/null.
-
-* "git diff --no-index" on binary files no longer outputs a bogus
- "diff --git" header line.
-
-* "git diff" hunk header patterns with multiple elements separated by LF
- were not used correctly.
-
-* Hunk headers in "git diff" default to using extended regular
- expressions, fixing some of the internal patterns on non-GNU
- platforms.
-
-* New config "diff.*.xfuncname" exposes extended regular expressions
- for user specified hunk header patterns.
-
-* "git gc" when ejecting otherwise unreachable objects from packfiles into
- loose form leaked memory.
-
-* "git index-pack" was recently broken and mishandled objects added by
- thin-pack completion processing under memory pressure.
-
-* "git index-pack" was recently broken and misbehaved when run from inside
- .git/objects/pack/ directory.
-
-* "git stash apply sash@{1}" was fixed to error out. Prior versions
- would have applied stash@{0} incorrectly.
-
-* "git stash apply" now offers a better suggestion on how to continue
- if the working tree is currently dirty.
-
-* "git for-each-ref --format=%(subject)" fixed for commits with no
- no newline in the message body.
-
-* "git remote" fixed to protect printf from user input.
-
-* "git remote show -v" now displays all URLs of a remote.
-
-* "git checkout -b branch" was confused when branch already existed.
-
-* "git checkout -q" once again suppresses the locally modified file list.
-
-* "git clone -q", "git fetch -q" asks remote side to not send
- progress messages, actually making their output quiet.
-
-* Cross-directory renames are no longer used when creating packs. This
- allows more graceful behavior on filesystems like sshfs.
-
-* Stale temporary files under $GIT_DIR/objects/pack are now cleaned up
- automatically by "git prune".
-
-* "git merge" once again removes directories after the last file has
- been removed from it during the merge.
-
-* "git merge" did not allocate enough memory for the structure itself when
- enumerating the parents of the resulting commit.
-
-* "git blame -C -C" no longer segfaults while trying to pass blame if
- it encounters a submodule reference.
-
-* "git rm" incorrectly claimed that you have local modifications when a
- path was merely stat-dirty.
-
-* "git svn" fixed to display an error message when 'set-tree' failed,
- instead of a Perl compile error.
-
-* "git submodule" fixed to handle checking out a different commit
- than HEAD after initializing the submodule.
-
-* The "git commit" error message when there are still unmerged
- files present was clarified to match "git write-tree".
-
-* "git init" was confused when core.bare or core.sharedRepository are set
- in system or user global configuration file by mistake. When --bare or
- --shared is given from the command line, these now override such
- settings made outside the repositories.
-
-* Some segfaults due to uncaught NULL pointers were fixed in multiple
- tools such as apply, reset, update-index.
-
-* Solaris builds now default to OLD_ICONV=1 to avoid compile warnings;
- Solaris 8 does not define NEEDS_LIBICONV by default.
-
-* "Git.pm" tests relied on unnecessarily more recent version of Perl.
-
-* "gitweb" triggered undef warning on commits without log messages.
-
-* "gitweb" triggered undef warnings on missing trees.
-
-* "gitweb" now removes PATH_INFO from its URLs so users don't have
- to manually set the URL in the gitweb configuration.
-
-* Bash completion removed support for legacy "git-fetch", "git-push"
- and "git-pull" as these are no longer installed. Dashless form
- ("git fetch") is still however supported.
-
-Many other documentation updates.

-GIT v1.6.0.4 Release Notes

-
-Fixes since v1.6.0.3
---------------------
-
-* 'git add -p' said "No changes" when only binary files were changed.
-
-* 'git archive' did not work correctly in bare repositories.
-
-* 'git checkout -t -b newbranch' when you are on detached HEAD was broken.
-
-* when we refuse to detect renames because there are too many new or
- deleted files, 'git diff' did not say how many there are.
-
-* 'git push --mirror' tried and failed to push the stash; there is no
- point in sending it to begin with.
-
-* 'git push' did not update the remote tracking reference if the corresponding
- ref on the remote end happened to be already up to date.
-
-* 'git pull $there $branch:$current_branch' did not work when you were on
- a branch yet to be born.
-
-* when giving up resolving a conflicted merge, 'git reset --hard' failed
- to remove new paths from the working tree.
-
-* 'git send-email' had a small fd leak while scanning directory.
-
-* 'git status' incorrectly reported a submodule directory as an untracked
- directory.
-
-* 'git svn' used deprecated 'git-foo' form of subcommand invocation.
-
-* 'git update-ref -d' to remove a reference did not honor --no-deref option.
-
-* Plugged small memleaks here and there.

-GIT v1.6.0.5 Release Notes
-==========================
-
-Fixes since v1.6.0.4
---------------------
-
-* "git checkout" used to crash when your HEAD was pointing at a deleted
- branch.
-
-* "git checkout" from an un-checked-out state did not allow switching out
- of the current branch.
-
-* "git diff" always allowed GIT_EXTERNAL_DIFF and --no-ext-diff was no-op for
- the command.
-
-* Giving 3 or more tree-ish to "git diff" is supposed to show the combined
- diff from second and subsequent trees to the first one, but the order was
- screwed up.
-
-* "git fast-export" did not export all tags.
-
-* "git ls-files --with-tree=<tree>" did not work with options other
- than -c, most notably with -m.
-
-* "git pack-objects" did not make its best effort to honor --max-pack-size
- option when a single first object already busted the given limit and
- placed many objects in a single pack.
-
-* "git-p4" fast import frontend was too eager to trigger its keyword expansion
- logic, even on a keyword-looking string that does not have closing '$' on the
- same line.
-
-* "git push $there" when the remote $there is defined in $GIT_DIR/branches/$there
- behaves more like what cg-push from Cogito used to work.
-
-* when giving up resolving a conflicted merge, "git reset --hard" failed
- to remove new paths from the working tree.
-
-* "git tag" did not complain when given mutually incompatible set of options.
-
-* The message constructed in the internal editor was discarded when "git
- tag -s" failed to sign the message, which was often caused by the user
- not configuring GPG correctly.
-
-* "make check" cannot be run without sparse; people may have meant to say
- "make test" instead, so suggest that.
-
-* Internal diff machinery had a corner case performance bug that choked on
- a large file with many repeated contents.
-
-* "git repack" used to grab objects out of packs marked with .keep
- into a new pack.
-
-* Many unsafe call to sprintf() style varargs functions are corrected.
-
-* Also contains quite a few documentation updates.

-GIT v1.6.0.6 Release Notes
-==========================
-
-Fixes since 1.6.0.5
--------------------
-
- * "git fsck" had a deep recursion that wasted stack space.
-
- * "git fast-export" and "git fast-import" choked on an old style
- annotated tag that lack the tagger information.
-
- * "git mergetool -- file" did not correctly skip "--" marker that
- signals the end of options list.
-
- * "git show $tag" segfaulted when an annotated $tag pointed at a
- nonexistent object.
-
- * "git show 2>error" when the standard output is automatically redirected
- to the pager redirected the standard error to the pager as well; there
- was no need to.
-
- * "git send-email" did not correctly handle list of addresses when
- they had quoted comma (e.g. "Lastname, Givenname" <mail@addre.ss>).
-
- * Logic to discover branch ancestry in "git svn" was unreliable when
- the process to fetch history was interrupted.
-
- * Removed support for an obsolete gitweb request URI, whose
- implementation ran "git diff" Porcelain, instead of using plumbing,
- which would have run an external diff command specified in the
- repository configuration as the gitweb user.
-
-Also contains numerous documentation typofixes.

-GIT v1.6.0 Release Notes
-========================
-
-User visible changes
---------------------
-
-With the default Makefile settings, most of the programs are now
-installed outside your $PATH, except for "git", "gitk" and
-some server side programs that need to be accessible for technical
-reasons. Invoking a git subcommand as "git-xyzzy" from the command
-line has been deprecated since early 2006 (and officially announced in
-1.5.4 release notes); use of them from your scripts after adding
-output from "git --exec-path" to the $PATH is still supported in this
-release, but users are again strongly encouraged to adjust their
-scripts to use "git xyzzy" form, as we will stop installing
-"git-xyzzy" hardlinks for built-in commands in later releases.
-
-An earlier change to page "git status" output was overwhelmingly unpopular
-and has been reverted.
-
-Source changes needed for porting to MinGW environment are now all in the
-main git.git codebase.
-
-By default, packfiles created with this version uses delta-base-offset
-encoding introduced in v1.4.4. Pack idx files are using version 2 that
-allows larger packs and added robustness thanks to its CRC checking,
-introduced in v1.5.2 and v1.4.4.5. If you want to keep your repositories
-backwards compatible past these versions, set repack.useDeltaBaseOffset
-to false or pack.indexVersion to 1, respectively.
-
-We used to prevent sample hook scripts shipped in templates/ from
-triggering by default by relying on the fact that we install them as
-unexecutable, but on some filesystems, this approach does not work.
-They are now shipped with ".sample" suffix. If you want to activate
-any of these samples as-is, rename them to drop the ".sample" suffix,
-instead of running "chmod +x" on them. For example, you can rename
-hooks/post-update.sample to hooks/post-update to enable the sample
-hook that runs update-server-info, in order to make repositories
-friendly to dumb protocols (i.e. HTTP).
-
-GIT_CONFIG, which was only documented as affecting "git config", but
-actually affected all git commands, now only affects "git config".
-GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
-not different from GIT_CONFIG in a useful way, is removed.
-
-The ".dotest" temporary area "git am" and "git rebase" use is now moved
-inside the $GIT_DIR, to avoid mistakes of adding it to the project by
-accident.
-
-An ancient merge strategy "stupid" has been removed.
-
-
-Updates since v1.5.6
---------------------
-
-(subsystems)
-
-* git-p4 in contrib learned "allowSubmit" configuration to control on
- which branch to allow "submit" subcommand.
-
-* git-gui learned to stage changes per-line.
-
-(portability)
-
-* Changes for MinGW port have been merged, thanks to Johannes Sixt and
- gangs.
-
-* Sample hook scripts shipped in templates/ are now suffixed with
- *.sample.
-
-* perl's in-place edit (-i) does not work well without backup files on Windows;
- some tests are rewritten to cope with this.
-
-(documentation)
-
-* Updated howto/update-hook-example
-
-* Got rid of usage of "git-foo" from the tutorial and made typography
- more consistent.
-
-* Disambiguating "--" between revs and paths is finally documented.
-
-(performance, robustness, sanity etc.)
-
-* index-pack used too much memory when dealing with a deep delta chain.
- This has been optimized.
-
-* reduced excessive inlining to shrink size of the "git" binary.
-
-* verify-pack checks the object CRC when using version 2 idx files.
-
-* When an object is corrupt in a pack, the object became unusable even
- when the same object is available in a loose form, We now try harder to
- fall back to these redundant objects when able. In particular, "git
- repack -a -f" can be used to fix such a corruption as long as necessary
- objects are available.
-
-* Performance of "git-blame -C -C" operation is vastly improved.
-
-* git-clone does not create refs in loose form anymore (it behaves as
- if you immediately ran git-pack-refs after cloning). This will help
- repositories with insanely large number of refs.
-
-* core.fsyncobjectfiles configuration can be used to ensure that the loose
- objects created will be fsync'ed (this is only useful on filesystems
- that does not order data writes properly).
-
-* "git commit-tree" plumbing can make Octopus with more than 16 parents.
- "git commit" has been capable of this for quite some time.
-
-(usability, bells and whistles)
-
-* even more documentation pages are now accessible via "man" and "git help".
-
-* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
- the discovery process of the toplevel of working tree; this may be useful
- when you are working in a slow network disk and are outside any working tree,
- as bash-completion and "git help" may still need to run in these places.
-
-* By default, stash entries never expire. Set reflogexpire in [gc
- "refs/stash"] to a reasonable value to get traditional auto-expiration
- behaviour back
-
-* Longstanding latency issue with bash completion script has been
- addressed. This will need to be backmerged to 'maint' later.
-
-* pager.<cmd> configuration variable can be used to enable/disable the
- default paging behaviour per command.
-
-* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
- manually.
-
-* git-am records the original tip of the branch in ORIG_HEAD before it
- starts applying patches.
-
-* git-apply can handle a patch that touches the same path more than once
- much better than before.
-
-* git-apply can be told not to trust the line counts recorded in the input
- patch but recount, with the new --recount option.
-
-* git-apply can be told to apply a patch to a path deeper than what the
- patch records with --directory option.
-
-* git-archive can be told to omit certain paths from its output using
- export-ignore attributes.
-
-* git-archive uses the zlib default compression level when creating
- zip archive.
-
-* git-archive's command line options --exec and --remote can take their
- parameters as separate command line arguments, similar to other commands.
- IOW, both "--exec=path" and "--exec path" are now supported.
-
-* With -v option, git-branch describes the remote tracking statistics
- similar to the way git-checkout reports by how many commits your branch
- is ahead/behind.
-
-* git-branch's --contains option used to always require a commit parameter
- to limit the branches with; it now defaults to list branches that
- contains HEAD if this parameter is omitted.
-
-* git-branch's --merged and --no-merged option used to always limit the
- branches relative to the HEAD, but they can now take an optional commit
- argument that is used in place of HEAD.
-
-* git-bundle can read the revision arguments from the standard input.
-
-* git-cherry-pick can replay a root commit now.
-
-* git-clone can clone from a remote whose URL would be rewritten by
- configuration stored in $HOME/.gitconfig now.
-
-* "git-clone --mirror" is a handy way to set up a bare mirror repository.
-
-* git-cvsserver learned to respond to "cvs co -c".
-
-* git-diff --check now checks leftover merge conflict markers.
-
-* "git-diff -p" learned to grab a better hunk header lines in
- BibTex, Pascal/Delphi, and Ruby files and also pays attention to
- chapter and part boundary in TeX documents.
-
-* When remote side used to have branch 'foo' and git-fetch finds that now
- it has branch 'foo/bar', it refuses to lose the existing remote tracking
- branch and its reflog. The error message has been improved to suggest
- pruning the remote if the user wants to proceed and get the latest set
- of branches from the remote, including such 'foo/bar'.
-
-* fast-export learned to export and import marks file; this can be used to
- interface with fast-import incrementally.
-
-* fast-import and fast-export learned to export and import gitlinks.
-
-* "gitk" left background process behind after being asked to dig very deep
- history and the user killed the UI; the process is killed when the UI goes
- away now.
-
-* git-rebase records the original tip of branch in ORIG_HEAD before it is
- rewound.
-
-* "git rerere" can be told to update the index with auto-reused resolution
- with rerere.autoupdate configuration variable.
-
-* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
- family. These notations are available in gitk as well, because the gitk
- command internally uses rev-parse to interpret its arguments.
-
-* git-rev-list learned --children option to show child commits it
- encountered during the traversal, instead of showing parent commits.
-
-* git-send-mail can talk not just over SSL but over TLS now.
-
-* git-shortlog honors custom output format specified with "--pretty=format:".
-
-* "git-stash save" learned --keep-index option. This lets you stash away the
- local changes and bring the changes staged in the index to your working
- tree for examination and testing.
-
-* git-stash also learned branch subcommand to create a new branch out of
- stashed changes.
-
-* git-status gives the remote tracking statistics similar to the way
- git-checkout reports by how many commits your branch is ahead/behind.
-
-* "git-svn dcommit" is now aware of auto-props setting the subversion user
- has.
-
-* You can tell "git status -u" to even more aggressively omit checking
- untracked files with --untracked-files=no.
-
-* Original SHA-1 value for "update-ref -d" is optional now.
-
-* Error codes from gitweb are made more descriptive where possible, rather
- than "403 forbidden" as we used to issue everywhere.
-
-(internal)
-
-* git-merge has been reimplemented in C.
-
-
-Fixes since v1.5.6
-------------------
-
-All of the fixes in v1.5.6 maintenance series are included in
-this release, unless otherwise noted.
-
- * git-clone ignored its -u option; the fix needs to be backported to
- 'maint';
-
- * git-mv used to lose the distinction between changes that are staged
- and that are only in the working tree, by staging both in the index
- after moving such a path.
-
- * "git-rebase -i -p" rewrote the parents to wrong ones when amending
- (either edit or squash) was involved, and did not work correctly
- when fast forwarding.

-
-* "git checkout $tree" did not trigger an error.
-
-* "git commit" tried to remove COMMIT_EDITMSG from the work tree by mistake.
-
-* "git describe --all" complained when a commit is described with a tag,
- which was nonsense.
-
-* "git diff --no-index --" did not trigger no-index (aka "use git-diff as
- a replacement of diff on untracked files") behaviour.
-
-* "git format-patch -1 HEAD" on a root commit failed to produce patch
- text.
-
-* "git fsck branch" did not work as advertised; instead it behaved the same
- way as "git fsck".
-
-* "git log --pretty=format:%s" did not handle a multi-line subject the
- same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
-
-* "git daemon", and "git merge-file" are more careful when freopen fails
- and barf, instead of going on and writing to unopened filehandle.
-
-* "git http-push" did not like some RFC 4918 compliant DAV server
- responses.
-
-* "git merge -s recursive" mistakenly overwritten an untracked file in the
- work tree upon delete/modify conflict.
-
-* "git merge -s recursive" didn't leave the index unmerged for entries with
- rename/delete conflicts.
-
-* "git merge -s recursive" clobbered untracked files in the work tree.
-
-* "git mv -k" with more than one erroneous paths misbehaved.
-
-* "git read-tree -m -u" hence branch switching incorrectly lost a

-GIT v1.6.1.2 Release Notes
-==========================
-
-Fixes since v1.6.1.1
---------------------
-
-* The logic for rename detection in internal diff used by commands like
- "git diff" and "git blame" has been optimized to avoid loading the same
- blob repeatedly.
-
-* We did not allow writing out a blob that is larger than 2GB for no good
- reason.
-
-* "git format-patch -o $dir", when $dir is a relative directory, used it
- as relative to the root of the work tree, not relative to the current
- directory.
-
-* v1.6.1 introduced an optimization for "git push" into a repository (A)
- that borrows its objects from another repository (B) to avoid sending
- objects that are available in repository B, when they are not yet used
- by repository A. However the code on the "git push" sender side was
- buggy and did not work when repository B had new objects that are not
- known by the sender. This caused pushing into a "forked" repository
- served by v1.6.1 software using "git push" from v1.6.1 sometimes did not
- work. The bug was purely on the "git push" sender side, and has been
- corrected.
-
-* "git status -v" did not paint its diff output in colour even when
- color.ui configuration was set.
-
-* "git ls-tree" learned --full-tree option to help Porcelain scripts that
- want to always see the full path regardless of the current working
- directory.
-
-* "git grep" incorrectly searched in work tree paths even when they are
- marked as assume-unchanged. It now searches in the index entries.
-
-* "git gc" with no grace period needlessly ejected packed but unreachable
- objects in their loose form, only to delete them right away.

-GIT v1.6.1.3 Release Notes
-==========================
-
-Fixes since v1.6.1.2
---------------------
-
-* "git diff --binary | git apply" pipeline did not work well when
- a binary blob is changed to a symbolic link.
-
-* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
- not work as expected.
-
-* "git grep" did not pass the -I (ignore binary) option when
- calling out an external grep program.
-
-* "git log" and friends include HEAD to the set of starting points
- when --all is given. This makes a difference when you are not
- on any branch.
-
-* "git mv" to move an untracked file to overwrite a tracked
- contents misbehaved.
-
-* "git merge -s octopus" with many potential merge bases did not
- work correctly.
-
-* RPM binary package installed the html manpages in a wrong place.
-
-Also includes minor documentation fixes and updates.

-GIT v1.6.1.4 Release Notes
-==========================
-
-Fixes since v1.6.1.3
---------------------
-
-* .gitignore learned to handle backslash as a quoting mechanism for
- comment introduction character "#".
- This fix was first merged to 1.6.2.1.
-
-* "git fast-export" produced wrong output with some parents missing from
- commits, when the history is clock-skewed.
-
-* "git fast-import" sometimes failed to read back objects it just wrote
- out and aborted, because it failed to flush stale cached data.
-
-* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
- deciding to descend into a subdirectory but they did not match the
- individual paths correctly. This caused pathspecs "abc/d ab" to match
- "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
- and then "ab" incorrectly matched "abc/0" when it shouldn't).
- This fix was first merged to 1.6.2.3.
-
-* import-zips script (in contrib) did not compute the common directory
- prefix correctly.
- This fix was first merged to 1.6.2.2.
-
-* "git init" segfaulted when given an overlong template location via
- the --template= option.
- This fix was first merged to 1.6.2.4.
-
-* "git repack" did not error out when necessary object was missing in the
- repository.
-
-* git-repack (invoked from git-gc) did not work as nicely as it should in
- a repository that borrows objects from neighbours via alternates
- mechanism especially when some packs are marked with the ".keep" flag
- to prevent them from being repacked.
- This fix was first merged to 1.6.2.3.

-GIT v1.6.1 Release Notes
-========================
-
-Updates since v1.6.0
---------------------
-
-When some commands (e.g. "git log", "git diff") spawn pager internally, we
-used to make the pager the parent process of the git command that produces
-output. This meant that the exit status of the whole thing comes from the
-pager, not the underlying git command. We swapped the order of the
-processes around and you will see the exit code from the command from now
-on.
-
-(subsystems)
-
-* gitk can call out to git-gui to view "git blame" output; git-gui in turn
- can run gitk from its blame view.
-
-* Various git-gui updates including updated translations.
-
-* Various gitweb updates from repo.or.cz installation.
-
-* Updates to emacs bindings.
-
-(portability)
-
-* A few test scripts used nonportable "grep" that did not work well on
- some platforms, e.g. Solaris.
-
-* Sample pre-auto-gc script has OS X support.
-
-* Makefile has support for (ancient) FreeBSD 4.9.
-
-(performance)
-
-* Many operations that are lstat(3) heavy can be told to pre-execute
- necessary lstat(3) in parallel before their main operations, which
- potentially gives much improved performance for cold-cache cases or in
- environments with weak metadata caching (e.g. NFS).
-
-* The underlying diff machinery to produce textual output has been
- optimized, which would result in faster "git blame" processing.
-
-* Most of the test scripts (but not the ones that try to run servers)
- can be run in parallel.
-
-* Bash completion of refnames in a repository with massive number of
- refs has been optimized.
-
-* Cygwin port uses native stat/lstat implementations when applicable,
- which leads to improved performance.
-
-* "git push" pays attention to alternate repositories to avoid sending
- unnecessary objects.
-
-* "git svn" can rebuild an out-of-date rev_map file.
-
-(usability, bells and whistles)
-
-* When you mistype a command name, git helpfully suggests what it guesses
- you might have meant to say. help.autocorrect configuration can be set
- to a non-zero value to accept the suggestion when git can uniquely
- guess.
-
-* The packfile machinery hopefully is more robust when dealing with
- corrupt packs if redundant objects involved in the corruption are
- available elsewhere.
-
-* "git add -N path..." adds the named paths as an empty blob, so that
- subsequent "git diff" will show a diff as if they are creation events.
-
-* "git add" gained a built-in synonym for people who want to say "stage
- changes" instead of "add contents to the staging area" which amounts
- to the same thing.
-
-* "git apply" learned --include=paths option, similar to the existing
- --exclude=paths option.
-
-* "git bisect" is careful about a user mistake and suggests testing of
- merge base first when good is not a strict ancestor of bad.
-
-* "git bisect skip" can take a range of commits.
-
-* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
- by default.
-
-* "git check-attr --stdin" can check attributes for multiple paths.
-
-* "git checkout --track origin/hack" used to be a syntax error. It now
- DWIMs to create a corresponding local branch "hack", i.e. acts as if you
- said "git checkout --track -b hack origin/hack".
-
-* "git checkout --ours/--theirs" can be used to check out one side of a
- conflicting merge during conflict resolution.
-
-* "git checkout -m" can be used to recreate the initial conflicted state
- during conflict resolution.
-
-* "git cherry-pick" can also utilize rerere for conflict resolution.
-
-* "git clone" learned to be verbose with -v
-
-* "git commit --author=$name" can look up author name from existing
- commits.
-
-* output from "git commit" has been reworded in a more concise and yet
- more informative way.
-
-* "git count-objects" reports the on-disk footprint for packfiles and
- their corresponding idx files.
-
-* "git daemon" learned --max-connections=<count> option.
-
-* "git daemon" exports REMOTE_ADDR to record client address, so that
- spawned programs can act differently on it.
-
-* "git describe --tags" favours closer lightweight tags than farther
- annotated tags now.
-
-* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
- configuration option.
-
-* "git diff" learned to put more sensible hunk headers for Python,
- HTML and ObjC contents.
-
-* "git diff" learned to vary the a/ vs b/ prefix depending on what are
- being compared, controlled by diff.mnemonicprefix configuration.
-
-* "git diff" learned --dirstat-by-file to count changed files, not number
- of lines, when summarizing the global picture.
-
-* "git diff" learned "textconv" filters --- a binary or hard-to-read
- contents can be munged into human readable form and the difference
- between the results of the conversion can be viewed (obviously this
- cannot produce a patch that can be applied, so this is disabled in
- format-patch among other things).
-
-* "--cached" option to "git diff has an easier to remember synonym "--staged",
- to ask "what is the difference between the given commit and the
- contents staged in the index?"
-
-* "git for-each-ref" learned "refname:short" token that gives an
- unambiguously abbreviated refname.
-
-* Auto-numbering of the subject lines is the default for "git
- format-patch" now.
-
-* "git grep" learned to accept -z similar to GNU grep.
-
-* "git help" learned to use GIT_MAN_VIEWER environment variable before
- using "man" program.
-
-* "git imap-send" can optionally talk SSL.
-
-* "git index-pack" is more careful against disk corruption while
- completing a thin pack.
-
-* "git log --check" and "git log --exit-code" passes their underlying diff
- status with their exit status code.
-
-* "git log" learned --simplify-merges, a milder variant of --full-history;
- "gitk --simplify-merges" is easier to view than with --full-history.
-
-* "git log" learned "--source" to show what ref each commit was reached
- from.
-
-* "git log" also learned "--simplify-by-decoration" to show the
- birds-eye-view of the topology of the history.
-
-* "git log --pretty=format:" learned "%d" format element that inserts
- names of tags that point at the commit.
-
-* "git merge --squash" and "git merge --no-ff" into an unborn branch are
- noticed as user errors.
-
-* "git merge -s $strategy" can use a custom built strategy if you have a
- command "git-merge-$strategy" on your $PATH.
-
-* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
- "-q"uietly.
-
-* "git push" can be told to reject deletion of refs with receive.denyDeletes
- configuration.
-
-* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
-
-* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
-
-* "git reflog expire branch" can be used in place of "git reflog expire
- refs/heads/branch".
-
-* "git remote show $remote" lists remote branches one-per-line now.
-
-* "git send-email" can be given revision range instead of files and
- maildirs on the command line, and automatically runs format-patch to
- generate patches for the given revision range.
-
-* "git submodule foreach" subcommand allows you to iterate over checked
- out submodules.
-
-* "git submodule sync" subcommands allows you to update the origin URL
- recorded in submodule directories from the toplevel .gitmodules file.
-
-* "git svn branch" can create new branches on the other end.
-
-* "gitweb" can use more saner PATH_INFO based URL.
-
-(internal)
-
-* "git hash-object" learned to lie about the path being hashed, so that
- correct gitattributes processing can be done while hashing contents
- stored in a temporary file.
-
-* various callers of git-merge-recursive avoid forking it as an external
- process.
-
-* Git class defined in "Git.pm" can be subclasses a bit more easily.
-
-* We used to link GNU regex library as a compatibility layer for some
- platforms, but it turns out it is not necessary on most of them.
-
-* Some path handling routines used fixed number of buffers used alternately
- but depending on the call depth, this arrangement led to hard to track
- bugs. This issue is being addressed.
-
-
-Fixes since v1.6.0
-------------------
-
-All of the fixes in v1.6.0.X maintenance series are included in this
-release, unless otherwise noted.
-
-* Porcelains implemented as shell scripts were utterly confused when you
- entered to a subdirectory of a work tree from sideways, following a
- symbolic link (this may need to be backported to older releases later).
-
-* Tracking symbolic links would work better on filesystems whose lstat()
- returns incorrect st_size value for them.
-
-* "git add" and "git update-index" incorrectly allowed adding S/F when S
- is a tracked symlink that points at a directory D that has a path F in
- it (we still need to fix a similar nonsense when S is a submodule and F
- is a path in it).
-
-* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
- --3way options given from the command line initially.
-
-* "git diff --stdin" used to take two trees on a line and compared them,
- but we dropped support for such a use case long time ago. This has
- been resurrected.
-
-* "git filter-branch" failed to rewrite a tag name with slashes in it.
-
-* "git http-push" did not understand URI scheme other than opaquelocktoken
- when acquiring a lock from the server (this may need to be backported to
- older releases later).
-
-* After "git rebase -p" stopped with conflicts while replaying a merge,
- "git rebase --continue" did not work (may need to be backported to older
- releases).
-
-* "git revert" records relative to which parent a revert was made when
- reverting a merge. Together with new documentation that explains issues
- around reverting a merge and merging from the updated branch later, this
- hopefully will reduce user confusion (this may need to be backported to
- older releases later).
-
-* "git rm --cached" used to allow an empty blob that was added earlier to
- be removed without --force, even when the file in the work tree has
- since been modified.
-
-* "git push --tags --all $there" failed with generic usage message without
- telling saying these two options are incompatible.
-
-* "git log --author/--committer" match used to potentially match the
- timestamp part, exposing internal implementation detail. Also these did
- not work with --fixed-strings match at all.
-
-* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
- correctly.

-
-* "git-blame -S" did not quite work near the commits that were given
- on the command line correctly.
-
-* "git diff --pickaxe-regexp" did not count overlapping matches
- correctly.
-
-* "git diff" did not feed files in work-tree representation to external
- diff and textconv.
-
-* "git-fetch" in a repository that was not cloned from anywhere said
- it cannot find 'origin', which was hard to understand for new people.
-
-* "git-format-patch --numbered-files --stdout" did not have to die of
- incompatible options; it now simply ignores --numbered-files as no files
- are produced anyway.
-
-* "git-ls-files --deleted" did not work well with GIT_DIR&GIT_WORK_TREE.
-
-* "git-read-tree A B C..." without -m option has been broken for a long
- time.
-
-* git-send-email ignored --in-reply-to when --no-thread was given.
-
-* 'git-submodule add' did not tolerate extra slashes and ./ in the path it
- accepted from the command line; it now is more lenient.
-
-* git-svn misbehaved when the project contained a path that began with
- two dashes.
-
-* import-zips script (in contrib) did not compute the common directory
- prefix correctly.
-
-* miscompilation of negated enum constants by old gcc (2.9) affected the
- codepaths to spawn subprocesses.

-
-* A fairly large and trivial memory leak while rev-list shows list of

-
-* The configuration parser had a buffer overflow while parsing an overlong
- value.
-
-* pruning reflog entries that are unreachable from the tip of the ref
- during "git reflog prune" (hence "git gc") was very inefficient.
-
-* "git-add -p" lacked a way to say "q"uit to refuse staging any hunks for
- the remaining paths. You had to say "d" and then ^C.
-
-* "git-checkout <tree-ish> <submodule>" did not update the index entry at
- the named path; it now does.
-
-* "git-fast-export" choked when seeing a tag that does not point at commit.
-
-* "git init" segfaulted when given an overlong template location via
- the --template= option.
-
-* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
- deciding to descend into a subdirectory but they did not match the
- individual paths correctly. This caused pathspecs "abc/d ab" to match
- "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
- and then "ab" incorrectly matched "abc/0" when it shouldn't).
-
-* "git-merge-recursive" was broken when a submodule entry was involved in
- a criss-cross merge situation.
-
-Many small documentation updates are included as well.

-GIT v1.6.2 Release Notes
-========================
-
-With the next major release, "git push" into a branch that is
-currently checked out will be refused by default. You can choose
-what should happen upon such a push by setting the configuration
-variable receive.denyCurrentBranch in the receiving repository.
-
-To ease the transition plan, the receiving repository of such a
-push running this release will issue a big warning when the
-configuration variable is missing. Please refer to:
-
- http://git.or.cz/gitwiki/GitFaq#non-bare
- http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
-
-for more details on the reason why this change is needed and the
-transition plan.
-
-For a similar reason, "git push $there :$killed" to delete the branch
-$killed in a remote repository $there, if $killed branch is the current
-branch pointed at by its HEAD, gets a large warning. You can choose what
-should happen upon such a push by setting the configuration variable
-receive.denyDeleteCurrent in the receiving repository.

-Updates since v1.6.1
---------------------
-
-(subsystems)
-
-* git-svn updates.
-
-* gitweb updates, including a new patch view and RSS/Atom feed
- improvements.
-
-* (contrib/emacs) git.el now has commands for checking out a branch,
- creating a branch, cherry-picking and reverting commits; vc-git.el
- is not shipped with git anymore (it is part of official Emacs).
-
-(performance)
-
-* pack-objects autodetects the number of CPUs available and uses threaded
- version.
-
-(usability, bells and whistles)
-
-* automatic typo correction works on aliases as well
-
-* @{-1} is a way to refer to the last branch you were on. This is
- accepted not only where an object name is expected, but anywhere
- a branch name is expected and acts as if you typed the branch name.
- E.g. "git branch --track mybranch @{-1}", "git merge @{-1}", and
- "git rev-parse --symbolic-full-name @{-1}" would work as expected.
-
-* When refs/remotes/origin/HEAD points at a remote tracking branch that
- has been pruned away, many git operations issued warning when they
- internally enumerated the refs. We now warn only when you say "origin"
- to refer to that pruned branch.
-
-* The location of .mailmap file can be configured, and its file format was
- enhanced to allow mapping an incorrect e-mail field as well.
-
-* "git add -p" learned 'g'oto action to jump directly to a hunk.
-
-* "git add -p" learned to find a hunk with given text with '/'.
-
-* "git add -p" optionally can be told to work with just the command letter
- without Enter.
-
-* when "git am" stops upon a patch that does not apply, it shows the
- title of the offending patch.
-
-* "git am --directory=<dir>" and "git am --reject" passes these options
- to underlying "git apply".
-
-* "git am" learned --ignore-date option.
-
-* "git blame" aligns author names better when they are spelled in
- non US-ASCII encoding.
-
-* "git clone" now makes its best effort when cloning from an empty
- repository to set up configuration variables to refer to the remote
- repository.
-
-* "git checkout -" is a shorthand for "git checkout @{-1}".
-
-* "git cherry" defaults to whatever the current branch is tracking (if
- exists) when the <upstream> argument is not given.
-
-* "git cvsserver" can be told not to add extra "via git-CVS emulator" to
- the commit log message it serves via gitcvs.commitmsgannotation
- configuration.
-
-* "git cvsserver" learned to handle 'noop' command some CVS clients seem
- to expect to work.
-
-* "git diff" learned a new option --inter-hunk-context to coalesce close
- hunks together and show context between them.
-
-* The definition of what constitutes a word for "git diff --color-words"
- can be customized via gitattributes, command line or a configuration.
-
-* "git diff" learned --patience to run "patience diff" algorithm.
-
-* "git filter-branch" learned --prune-empty option that discards commits
- that do not change the contents.
-
-* "git fsck" now checks loose objects in alternate object stores, instead
- of misreporting them as missing.
-
-* "git gc --prune" was resurrected to allow "git gc --no-prune" and
- giving non-default expiration period e.g. "git gc --prune=now".
-
-* "git grep -w" and "git grep" for fixed strings have been optimized.
-
-* "git mergetool" learned -y(--no-prompt) option to disable prompting.
-
-* "git rebase -i" can transplant a history down to root to elsewhere
- with --root option.
-
-* "git reset --merge" is a new mode that works similar to the way
- "git checkout" switches branches, taking the local changes while
- switching to another commit.
-
-* "git submodule update" learned --no-fetch option.
-
-* "git tag" learned --contains that works the same way as the same option
- from "git branch".

-Fixes since v1.6.1
-------------------
-
-All of the fixes in v1.6.1.X maintenance series are included in this
-release, unless otherwise noted.
-
-Here are fixes that this release has, but have not been backported to
-v1.6.1.X series.
-
-* "git-add sub/file" when sub is a submodule incorrectly added the path to
- the superproject.
-
-* "git bundle" did not exclude annotated tags even when a range given
- from the command line wanted to.
-
-* "git filter-branch" unnecessarily refused to work when you had
- checked out a different commit from what is recorded in the superproject
- index in a submodule.
-
-* "git filter-branch" incorrectly tried to update a nonexistent work tree
- at the end when it is run in a bare repository.
-
-* "git gc" did not work if your repository was created with an ancient git
- and never had any pack files in it before.
-
-* "git mergetool" used to ignore autocrlf and other attributes
- based content rewriting.
-
-* branch switching and merges had a silly bug that did not validate
- the correct directory when making sure an existing subdirectory is
- clean.
-
-* "git -p cmd" when cmd is not a built-in one left the display in funny state
- when killed in the middle.

-GIT v1.6.3.1 Release Notes
-==========================
-
-Fixes since v1.6.3
-------------------
-
-* "git checkout -b new-branch" with a staged change in the index
- incorrectly primed the in-index cache-tree, resulting a wrong tree
- object to be written out of the index. This is a grave regression
- since the last 1.6.2.X maintenance release.

-GIT v1.6.3.2 Release Notes
-==========================
-
-Fixes since v1.6.3.1
---------------------
-
- * A few codepaths picked up the first few bytes from an sha1[] by
- casting the (char *) pointer to (int *); GCC 4.4 did not like this,
- and aborted compilation.
-
- * Some unlink(2) failures went undiagnosed.
-
- * The "recursive" merge strategy misbehaved when faced rename/delete
- conflicts while coming up with an intermediate merge base.
-
- * The low-level merge algorithm did not handle a degenerate case of
- merging a file with itself using itself as the common ancestor
- gracefully. It should produce the file itself, but instead
- produced an empty result.
-
- * GIT_TRACE mechanism segfaulted when tracing a shell-quoted aliases.
-
- * OpenBSD also uses st_ctimspec in "struct stat", instead of "st_ctim".
-
- * With NO_CROSS_DIRECTORY_HARDLINKS, "make install" can be told not to
- create hardlinks between $(gitexecdir)/git-$builtin_commands and
- $(bindir)/git.
-
- * command completion code in bash did not reliably detect that we are
- in a bare repository.
-
- * "git add ." in an empty directory complained that pathspec "." did not
- match anything, which may be technically correct, but not useful. We
- silently make it a no-op now.
-
- * "git add -p" (and "patch" action in "git add -i") was broken when
- the first hunk that adds a line at the top was split into two and
- both halves are marked to be used.
-
- * "git blame path" misbehaved at the commit where path became file
- from a directory with some files in it.
-
- * "git for-each-ref" had a segfaulting bug when dealing with a tag object
- created by an ancient git.
-
- * "git format-patch -k" still added patch numbers if format.numbered
- configuration was set.
-
- * "git grep --color ''" did not terminate. The command also had
- subtle bugs with its -w option.
-
- * http-push had a small use-after-free bug.
-
- * "git push" was converting OFS_DELTA pack representation into less
- efficient REF_DELTA representation unconditionally upon transfer,
- making the transferred data unnecessarily larger.
-
- * "git remote show origin" segfaulted when origin was still empty.
-
-Many other general usability updates around help text, diagnostic messages
-and documentation are included as well.

-GIT v1.6.3.3 Release Notes
-==========================
-
-Fixes since v1.6.3.2
---------------------
-
- * "git archive" running on Cygwin can get stuck in an infinite loop.
-
- * "git daemon" did not correctly parse the initial line that carries
- virtual host request information.
-
- * "git diff --textconv" leaked memory badly when the textconv filter
- errored out.
-
- * The built-in regular expressions to pick function names to put on
- hunk header lines for java and objc were very inefficiently written.
-
- * in certain error situations git-fetch (and git-clone) on Windows didn't
- detect connection abort and ended up waiting indefinitely.
-
- * import-tars script (in contrib) did not import symbolic links correctly.
-
- * http.c used CURLOPT_SSLKEY even on libcURL version 7.9.2, even though
- it was only available starting 7.9.3.
-
- * low-level filelevel merge driver used return value from strdup()
- without checking if we ran out of memory.
-
- * "git rebase -i" left stray closing parenthesis in its reflog message.
-
- * "git remote show" did not show all the URLs associated with the named
- remote, even though "git remote -v" did. Made them consistent by
- making the former show all URLs.
-
- * "whitespace" attribute that is set was meant to detect all errors known
- to git, but it told git to ignore trailing carriage-returns.
-
-Includes other documentation fixes.

-GIT v1.6.3.4 Release Notes
-==========================
-
-Fixes since v1.6.3.3
---------------------
-
- * "git add --no-ignore-errors" did not override configured
- add.ignore-errors configuration.
-
- * "git apply --whitespace=fix" did not fix trailing whitespace on an
- incomplete line.
-
- * "git branch" opened too many commit objects unnecessarily.
-
- * "git checkout -f $commit" with a path that is a file (or a symlink) in
- the work tree to a commit that has a directory at the path issued an
- unnecessary error message.
-
- * "git diff -c/--cc" was very inefficient in coalescing the removed lines
- shared between parents.
-
- * "git diff -c/--cc" showed removed lines at the beginning of a file
- incorrectly.
-
- * "git remote show nickname" did not honor configured
- remote.nickname.uploadpack when inspecting the branches at the remote.
-
- * "git request-pull" when talking to the terminal for a preview
- showed some of the output in the pager.
-
- * "git request-pull start nickname [end]" did not honor configured
- remote.nickname.uploadpack when it ran git-ls-remote against the remote
- repository to learn the current tip of branches.
-
-Includes other documentation updates and minor fixes.

-GIT v1.6.3 Release Notes
-========================
-
-With the next major release, "git push" into a branch that is
-currently checked out will be refused by default. You can choose
-what should happen upon such a push by setting the configuration
-variable receive.denyCurrentBranch in the receiving repository.
-
-To ease the transition plan, the receiving repository of such a
-push running this release will issue a big warning when the
-configuration variable is missing. Please refer to:
-
- http://git.or.cz/gitwiki/GitFaq#non-bare
- http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
-
-for more details on the reason why this change is needed and the
-transition plan.
-
-For a similar reason, "git push $there :$killed" to delete the branch
-$killed in a remote repository $there, if $killed branch is the current
-branch pointed at by its HEAD, gets a large warning. You can choose what
-should happen upon such a push by setting the configuration variable
-receive.denyDeleteCurrent in the receiving repository.
-
-When the user does not tell "git push" what to push, it has always
-pushed matching refs. For some people it is unexpected, and a new
-configuration variable push.default has been introduced to allow
-changing a different default behaviour. To advertise the new feature,
-a big warning is issued if this is not configured and a git push without
-arguments is attempted.
-
-
-Updates since v1.6.2
---------------------
-
-(subsystems)
-
-* various git-svn updates.
-
-* git-gui updates, including an update to Russian translation, and a
- fix to an infinite loop when showing an empty diff.
-
-* gitk updates, including an update to Russian translation and improved Windows
- support.
-
-(performance)
-
-* many uses of lstat(2) in the codepath for "git checkout" have been
- optimized out.
-
-(usability, bells and whistles)
-
-* Boolean configuration variable yes/no can be written as on/off.
-
-* rsync:/path/to/repo can be used to run git over rsync for local
- repositories. It may not be useful in practice; meant primarily for
- testing.
-
-* http transport learned to prompt and use password when fetching from or
- pushing to http://user@host.xz/ URL.
-
-* (msysgit) progress output that is sent over the sideband protocol can
- be handled appropriately in Windows console.
-
-* "--pretty=<style>" option to the log family of commands can now be
- spelled as "--format=<style>". In addition, --format=%formatstring
- is a short-hand for --pretty=tformat:%formatstring.
-
-* "--oneline" is a synonym for "--pretty=oneline --abbrev-commit".
-
-* "--graph" to the "git log" family can draw the commit ancestry graph
- in colors.
-
-* If you realize that you botched the patch when you are editing hunks
- with the 'edit' action in git-add -i/-p, you can abort the editor to
- tell git not to apply it.
-
-* @{-1} is a new way to refer to the last branch you were on introduced in
- 1.6.2, but the initial implementation did not teach this to a few
- commands. Now the syntax works with "branch -m @{-1} newname".
-
-* git-archive learned --output=<file> option.
-
-* git-archive takes attributes from the tree being archived; strictly
- speaking, this is an incompatible behaviour change, but is a good one.
- Use --worktree-attributes option to allow it to read attributes from
- the work tree as before (deprecated git-tar tree command always reads
- attributes from the work tree).
-
-* git-bisect shows not just the number of remaining commits whose goodness
- is unknown, but also shows the estimated number of remaining rounds.
-
-* You can give --date=<format> option to git-blame.
-
-* "git-branch -r" shows HEAD symref that points at a remote branch in
- interest of each tracked remote repository.
-
-* "git-branch -v -v" is a new way to get list of names for branches and the
- "upstream" branch for them.
-
-* git-config learned -e option to open an editor to edit the config file
- directly.
-
-* git-clone runs post-checkout hook when run without --no-checkout.
-
-* git-difftool is now part of the officially supported command, primarily
- maintained by David Aguilar.
-
-* git-for-each-ref learned a new "upstream" token.
-
-* git-format-patch can be told to use attachment with a new configuration,
- format.attach.
-
-* git-format-patch can be told to produce deep or shallow message threads.
-
-* git-format-patch can be told to always add sign-off with a configuration
- variable.
-
-* git-format-patch learned format.headers configuration to add extra
- header fields to the output. This behaviour is similar to the existing
- --add-header=<header> option of the command.
-
-* git-format-patch gives human readable names to the attached files, when
- told to send patches as attachments.
-
-* git-grep learned to highlight the found substrings in color.
-
-* git-imap-send learned to work around Thunderbird's inability to easily
- disable format=flowed with a new configuration, imap.preformattedHTML.
-
-* git-rebase can be told to rebase the series even if your branch is a
- descendant of the commit you are rebasing onto with --force-rebase
- option.
-
-* git-rebase can be told to report diffstat with the --stat option.
-
-* Output from git-remote command has been vastly improved.
-
-* "git remote update --prune $remote" updates from the named remote and
- then prunes stale tracking branches.
-
-* git-send-email learned --confirm option to review the Cc: list before
- sending the messages out.
-
-(developers)
-
-* Test scripts can be run under valgrind.
-
-* Test scripts can be run with installed git.
-
-* Makefile learned 'coverage' option to run the test suites with
- coverage tracking enabled.
-
-* Building the manpages with docbook-xsl between 1.69.1 and 1.71.1 now
- requires setting DOCBOOK_SUPPRESS_SP to work around a docbook-xsl bug.
- This workaround used to be enabled by default, but causes problems
- with newer versions of docbook-xsl. In addition, there are a few more
- knobs you can tweak to work around issues with various versions of the
- docbook-xsl package. See comments in Documentation/Makefile for details.
-
-* Support for building and testing a subset of git on a system without a
- working perl has been improved.

-All of the fixes in v1.6.2.X maintenance series are included in this
-release, unless otherwise noted.
-
-Here are fixes that this release has, but have not been backported to
-v1.6.2.X series.
-
-* "git-apply" rejected a patch that swaps two files (i.e. renames A to B
- and B to A at the same time). May need to be backported by cherry
- picking d8c81df and then 7fac0ee).
-
-* The initial checkout did not read the attributes from the .gitattribute
- file that is being checked out.
-
-* git-gc spent excessive amount of time to decide if an object appears
- in a locally existing pack (if needed, backport by merging 69e020a).

-GIT v1.6.4.1 Release Notes
-==========================
-
-Fixes since v1.6.4
-------------------
-
- * An unquoted value in the configuration file, when it contains more than
- one whitespaces in a row, got them replaced with a single space.
-
- * "git am" used to accept a single piece of e-mail per file (not a mbox)
- as its input, but multiple input format support in v1.6.4 broke it.
- Apparently many people have been depending on this feature.
-
- * The short help text for "git filter-branch" command was a single long
- line, wrapped by terminals, and was hard to read.
-
- * The "recursive" strategy of "git merge" segfaulted when a merge has
- more than one merge-bases, and merging of these merge-bases involves
- a rename/rename or a rename/add conflict.
-
- * "git pull --rebase" did not use the right fork point when the
- repository has already fetched from the upstream that rewinds the
- branch it is based on in an earlier fetch.
-
- * Explain the concept of fast-forward more fully in "git push"
- documentation, and hint to refer to it from an error message when the
- command refuses an update to protect the user.
-
- * The default value for pack.deltacachesize, used by "git repack", is now
- 256M, instead of unbounded. Otherwise a repack of a moderately sized
- repository would needlessly eat into swap.
-
- * Document how "git repack" (hence "git gc") interacts with a repository
- that borrows its objects from other repositories (e.g. ones created by
- "git clone -s").
-
- * "git show" on an annotated tag lacked a delimiting blank line between
- the tag itself and the contents of the object it tags.
-
- * "git verify-pack -v" erroneously reported number of objects with too
- deep delta depths as "chain length 0" objects.
-
- * Long names of authors and committers outside US-ASCII were sometimes
- incorrectly shown in "gitweb".
-
-Other minor documentation updates are included.

-Fixes since v1.6.4.1
---------------------
-
-* --date=relative output between 1 and 5 years ago rounded the number of
- years when saying X years Y months ago, instead of rounding it down.
-
-* "git add -p" did not handle changes in executable bits correctly
- (a regression around 1.6.3).
-
-* "git apply" did not honor GNU diff's convention to mark the creation/deletion
- event with UNIX epoch timestamp on missing side.
-
-* "git checkout" incorrectly removed files in a directory pointed by a
- symbolic link during a branch switch that replaces a directory with
- a symbolic link.
-
-* "git clean -d -f" happily descended into a subdirectory that is managed by a
- separate git repository. It now requires two -f options for safety.
-
-* "git fetch/push" over http transports had two rather grave bugs.
-
-* "git format-patch --cover-letter" did not prepare the cover letter file
- for use with non-ASCII strings when there are the series contributors with
- non-ASCII names.
-
-* "git pull origin branch" and "git fetch origin && git merge origin/branch"
- left different merge messages in the resulting commit.

-
-* "git clone" from an empty repository gave unnecessary error message,
- even though it did everything else correctly.
-
-* "git cvsserver" invoked git commands via "git-foo" style, which has long
- been deprecated.
-
-* "git fetch" and "git clone" had an extra sanity check to verify the
- presence of the corresponding *.pack file before downloading *.idx
- file by issuing a HEAD request. Github server however sometimes
- gave 500 (Internal server error) response to HEAD even if a GET
- request for *.pack file to the same URL would have succeeded, and broke
- clone over HTTP from some of their repositories. As a workaround, this
- verification has been removed (as it is not absolutely necessary).
-
-* "git grep" did not like relative pathname to refer outside the current
- directory when run from a subdirectory.
-
-* an error message from "git push" was formatted in a very ugly way.
-
-* "git svn" did not quote the subversion user name correctly when
- running its author-prog helper program.

-
-* The workaround for Github server that sometimes gave 500 (Internal server
- error) response to HEAD requests in 1.6.4.3 introduced a regression that
- caused re-fetching projects over http to segfault in certain cases due
- to uninitialized pointer being freed.
-
-* "git pull" on an unborn branch used to consider anything in the work
- tree and the index discardable.
-
-* "git diff -b/w" did not work well on the incomplete line at the end of
- the file, due to an incorrect hashing of lines in the low-level xdiff
- routines.
-
-* "git checkout-index --prefix=$somewhere" used to work when $somewhere is
- a symbolic link to a directory elsewhere, but v1.6.4.2 broke it.
-
-* "git unpack-objects --strict", invoked when receive.fsckobjects
- configuration is set in the receiving repository of "git push", did not
- properly check the objects, especially the submodule links, it received.

-
-(performance)
-
- * Many repeated use of lstat() are optimized out in "checkout" codepath.

-(usability, bells and whistles)
-
- * "git add --edit" lets users edit the whole patch text to fine-tune what
- is added to the index.
-
- * "git am" accepts StGIT series file as its input.
-
- * "git bisect skip" skips to a more randomly chosen place in the hope
- to avoid testing a commit that is too close to a commit that is
- already known to be untestable.
-
- * "git cvsexportcommit" learned -k option to stop CVS keywords expansion
-
- * "git fast-export" learned to handle history simplification more
- gracefully.
-
- * "git fast-export" learned an option --tag-of-filtered-object to handle
- dangling tags resulting from history simplification more usefully.
-
- * "git grep" learned -p option to show the location of the match using the
- same context hunk marker "git diff" uses.
-
- * https transport can optionally be told that the used client
- certificate is password protected, in which case it asks the
- password only once.
-
- * "git imap-send" is IPv6 aware.
-
- * "git log --graph" draws graphs more compactly by using horizontal lines
- when able.
-
- * "git log --decorate" shows shorter refnames by stripping well-known
- refs/* prefix.
-
- * "git push $name" honors remote.$name.pushurl if present before
- using remote.$name.url. In other words, the URL used for fetching
- and pushing can be different.
-
- * "git send-email" understands quoted aliases in .mailrc files (might
- have to be backported to 1.6.3.X).
-
- * "git send-email" can fetch the sender address from the configuration
- variable "sendmail.from" (and "sendmail.<identity>.from").
-
- * "git show-branch" can color its output.
-
- * "add" and "update" subcommands to "git submodule" learned --reference
- option to use local clone with references.
-
- * "git submodule update" learned --rebase option to update checked
- out submodules by rebasing the local changes.
-
- * "gitweb" can optionally use gravatar to adorn author/committer names.

- directories in the output, 2009-06-13) may need to be cherry-picked
- to backport this fix.
-
- * The way Git.pm sets up a Repository object was not friendly to callers
- that chdir around. It now internally records the repository location
- as an absolute path when autodetected.
-
- * Removing a section with "git config --remove-section", when its
- section header has a variable definition on the same line, lost
- that variable definition.
-
- * "git rebase -p --onto" used to always leave side branches of a merge
- intact, even when both branches are subject to rewriting.
-
- * "git repack" used to faithfully follow grafts and considered true
- parents recorded in the commit object unreachable from the commit.
- After such a repacking, you cannot remove grafts without corrupting
- the repository.

-
- * info/grafts file didn't ignore trailing CR at the end of lines.
-
- * Packages generated on newer FC were unreadable by older versions of
- RPM as the new default is to use stronger hash.
-
- * output from "git blame" was unreadable when the file ended in an
- incomplete line.
-
- * "git add -i/-p" didn't handle deletion of empty files correctly.
-
- * "git clone" takes up to two parameters, but did not complain when
- given more arguments than necessary and silently ignored them.
-
- * "git cvsimport" did not read files given as command line arguments
- correctly when it is run from a subdirectory.
-
- * "git diff --color-words -U0" didn't work correctly.
-
- * The handling of blank lines at the end of file by "git diff/apply
- --whitespace" was inconsistent with the other kinds of errors.
- They are now colored, warned against, and fixed the same way as others.
-
- * There was no way to allow blank lines at the end of file without
- allowing extra blanks at the end of lines. You can use blank-at-eof
- and blank-at-eol whitespace error class to specify them separately.
- The old trailing-space error class is now a short-hand to set both.
-
- * "-p" option to "git format-patch" was supposed to suppress diffstat
- generation, but it was broken since 1.6.1.
-
- * "git imap-send" did not compile cleanly with newer OpenSSL.
-
- * "git help -a" outside of a git repository was broken.
-
- * "git ls-files -i" was supposed to be inverse of "git ls-files" without -i
- with respect to exclude patterns, but it was broken since 1.6.5.2.
-
- * "git ls-remote" outside of a git repository over http was broken.
-
- * "git rebase -i" gave bogus error message when the command word was
- misspelled.
-
- * "git receive-pack" that is run in response to "git push" did not run
- garbage collection nor update-server-info, but in larger hosting sites,
- these almost always need to be run. To help site administrators, the
- command now runs "gc --auto" and "u-s-i" by setting receive.autogc
- and receive.updateserverinfo configuration variables, respectively.
-
- * Release notes spelled the package name with incorrect capitalization.
-
- * "gitweb" did not escape non-ascii characters correctly in the URL.
-
- * "gitweb" showed "patch" link even for merge commits.
-
- * "gitweb" showed incorrect links for blob line numbers in pathinfo mode.

-Git v1.6.5.4 Release Notes
-==========================
-
-Fixes since v1.6.5.3
---------------------
-
- * "git help" (without argument) used to check if you are in a directory
- under git control. There was no breakage in behaviour per-se, but this
- was unnecessary.
-
- * "git prune-packed" gave progress output even when its standard error is
- not connected to a terminal; this caused cron jobs that run it to
- produce crufts.
-
- * "git pack-objects --all-progress" is an option to ask progress output
- from write-object phase _if_ progress output were to be produced, and
- shouldn't have forced the progress output.
-
- * "git apply -p<n> --directory=<elsewhere>" did not work well for a
- non-default value of n.
-
- * "git merge foo HEAD" was misparsed as an old-style invocation of the
- command and produced a confusing error message. As it does not specify
- any other branch to merge, it shouldn't be mistaken as such. We will
- remove the old style "git merge <message> HEAD <commit>..." syntax in
- future versions, but not in this release,
-
- * "git merge -m <message> <branch>..." added the standard merge message
- on its own after user-supplied message, which should have overridden the
- standard one.
-
-Other minor documentation updates are included.

-Git v1.6.5.5 Release Notes
-==========================
-
-Fixes since v1.6.5.4
---------------------
-
- * Manual pages can be formatted with older xmlto again.
-
- * GREP_OPTIONS exported from user's environment could have broken
- our scripted commands.
-
- * In configuration files, a few variables that name paths can begin with
- ~/ and ~username/ and they are expanded as expected. This is not a
- bugfix but 1.6.6 will have this and without backporting users cannot
- easily use the same ~/.gitconfig across versions.
-
- * "git diff -B -M" did the same computation to hash lines of contents
- twice, and held onto memory after it has used the data in it
- unnecessarily before it freed.
-
- * "git diff -B" and "git diff --dirstat" was not counting newly added
- contents correctly.
-
- * "git format-patch revisions... -- path" issued an incorrect error
- message that suggested to use "--" on the command line when path
- does not exist in the current work tree (it is a separate matter if
- it makes sense to limit format-patch with pathspecs like that
- without using the --full-diff option).
-
- * "git grep -F -i StRiNg" did not work as expected.
-
- * Enumeration of available merge strategies iterated over the list of
- commands in a wrong way, sometimes producing an incorrect result.
-
- * "git shortlog" did not honor the "encoding" header embedded in the
- commit object like "git log" did.
-
- * Reading progress messages that come from the remote side while running
- "git pull" is given precedence over reading the actual pack data to
- prevent garbled progress message on the user's terminal.
-
- * "git rebase" got confused when the log message began with certain
- strings that looked like Subject:, Date: or From: header.
-
- * "git reset" accidentally run in .git/ directory checked out the
- work tree contents in there.
-
-
-Other minor documentation updates are included.

-Git v1.6.5.6 Release Notes
-==========================
-
-Fixes since v1.6.5.5
---------------------
-
- * "git add -p" had a regression since v1.6.5.3 that broke deletion of
- non-empty files.
-
- * "git archive -o o.zip -- Makefile" produced an archive in o.zip
- but in POSIX tar format.
-
- * Error message given to "git pull --rebase" when the user didn't give
- enough clue as to what branch to integrate with still talked about
- "merging with" the branch.
-
- * Error messages given by "git merge" when the merge resulted in a
- fast-forward still were in plumbing lingo, even though in v1.6.5
- we reworded messages in other cases.
-
- * The post-upload-hook run by upload-pack in response to "git fetch" has
- been removed, due to security concerns (the hook first appeared in
- 1.6.5).

-Git v1.6.5.7 Release Notes
-==========================
-
-Fixes since v1.6.5.6
---------------------
-
-* If a user specifies a color for a <slot> (i.e. a class of things to show
- in a particular color) that is known only by newer versions of git
- (e.g. "color.diff.func" was recently added for upcoming 1.6.6 release),
- an older version of git should just ignore them. Instead we diagnosed
- it as an error.
-
-* With help.autocorrect set to non-zero value, the logic to guess typos
- in the subcommand name misfired and ran a random nonsense command.
-
-* If a command is run with an absolute path as a pathspec inside a bare
- repository, e.g. "rev-list HEAD -- /home", the code tried to run
- strlen() on NULL, which is the result of get_git_work_tree(), and
- segfaulted.

-Git v1.6.5.8 Release Notes
-==========================
-
-Fixes since v1.6.5.7

-
-* "git count-objects" did not handle packfiles that are bigger than 4G on
- platforms with 32-bit off_t.
-
-* "git rebase -i" did not abort cleanly if it failed to launch the editor.
-
-* "git blame" did not work well when commit lacked the author name.

- that is not a commit.
-
-* "git reset --hard" did not work correctly when GIT_WORK_TREE environment
- variable is used to point at the root of the true work tree.

-* "git grep" fed a buffer that is not NUL-terminated to underlying
- regexec().
-
-* "git checkout -m other" while on a branch that does not have any commit

-GIT v1.6.5 Release Notes
-========================
-
-In git 1.7.0, which was planned to be the release after 1.6.5, "git
-push" into a branch that is currently checked out will be refused by
-default.
-
-You can choose what should happen upon such a push by setting the
-configuration variable receive.denyCurrentBranch in the receiving
-repository.
-
-Also, "git push $there :$killed" to delete the branch $killed in a remote
-repository $there, when $killed branch is the current branch pointed at by
-its HEAD, will be refused by default.
-
-You can choose what should happen upon such a push by setting the
-configuration variable receive.denyDeleteCurrent in the receiving
-repository.
-
-To ease the transition plan, the receiving repository of such a
-push running this release will issue a big warning when the
-configuration variable is missing. Please refer to:
-

-transition plan.
-
-Updates since v1.6.4
---------------------
-
-(subsystems)
-
- * various updates to gitk, git-svn and gitweb.
-
-(portability)
-
- * more improvements on mingw port.
-
- * mingw will also give FRSX as the default value for the LESS
- environment variable when the user does not have one.
-
- * initial support to compile git on Windows with MSVC.
-
-(performance)
-
- * On major platforms, the system can be compiled to use with Linus's
- block-sha1 implementation of the SHA-1 hash algorithm, which
- outperforms the default fallback implementation we borrowed from
- Mozilla.
-
- * Unnecessary inefficiency in deepening of a shallow repository has
- been removed.
-
- * "git clone" does not grab objects that it does not need (i.e.
- referenced only from refs outside refs/heads and refs/tags
- hierarchy) anymore.
-
- * The "git" main binary used to link with libcurl, which then dragged
- in a large number of external libraries. When using basic plumbing
- commands in scripts, this unnecessarily slowed things down. We now
- implement http/https/ftp transfer as a separate executable as we
- used to.
-
- * "git clone" run locally hardlinks or copies the files in .git/ to
- newly created repository. It used to give new mtime to copied files,
- but this delayed garbage collection to trigger unnecessarily in the
- cloned repository. We now preserve mtime for these files to avoid
- this issue.
-
-(usability, bells and whistles)
-
- * Human writable date format to various options, e.g. --since=yesterday,
- master@{2000.09.17}, are taught to infer some omitted input properly.
-
- * A few programs gave verbose "advice" messages to help uninitiated
- people when issuing error messages. An infrastructure to allow
- users to squelch them has been introduced, and a few such messages
- can be silenced now.
-
- * refs/replace/ hierarchy is designed to be usable as a replacement
- of the "grafts" mechanism, with the added advantage that it can be
- transferred across repositories.
-
- * "git am" learned to optionally ignore whitespace differences.
-
- * "git am" handles input e-mail files that has CRLF line endings sensibly.
-
- * "git am" learned "--scissors" option to allow you to discard early part
- of an incoming e-mail.
-
- * "git archive -o output.zip" works without being told what format to
- use with an explicit "--format=zip".option.
-
- * "git checkout", "git reset" and "git stash" learned to pick and
- choose to use selected changes you made, similar to "git add -p".
-
- * "git clone" learned a "-b" option to pick a HEAD to check out
- different from the remote's default branch.
-
- * "git clone" learned --recursive option.
-
- * "git clone" from a local repository on a different filesystem used to
- copy individual object files without preserving the old timestamp, giving
- them extra lifetime in the new repository until they gc'ed.
-
- * "git commit --dry-run $args" is a new recommended way to ask "what would
- happen if I try to commit with these arguments."
-
- * "git commit --dry-run" and "git status" shows conflicted paths in a
- separate section to make them easier to spot during a merge.
-
- * "git cvsimport" now supports password-protected pserver access even
- when the password is not taken from ~/.cvspass file.
-
- * "git fast-export" learned --no-data option that can be useful when
- reordering commits and trees without touching the contents of
- blobs.
-
- * "git fast-import" has a pair of new front-end in contrib/ area.
-
- * "git init" learned to mkdir/chdir into a directory when given an
- extra argument (i.e. "git init this").
-
- * "git instaweb" optionally can use mongoose as the web server.
-
- * "git log --decorate" can optionally be told with --decorate=full to
- give the reference name in full.
-
- * "git merge" issued an unnecessarily scary message when it detected
- that the merge may have to touch the path that the user has local
- uncommitted changes to. The message has been reworded to make it
- clear that the command aborted, without doing any harm.
-
- * "git push" can be told to be --quiet.
-
- * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
- that is derived from the URL used for fetching.
-
- * informational output from "git reset" that lists the locally modified
- paths is made consistent with that of "git checkout $another_branch".
-
- * "git submodule" learned to give submodule name to scripts run with
- "foreach" subcommand.
-
- * various subcommands to "git submodule" learned --recursive option.
-
- * "git submodule summary" learned --files option to compare the work
- tree vs the commit bound at submodule path, instead of comparing
- the index.
-
- * "git upload-pack", which is the server side support for "git clone" and
- "git fetch", can call a new post-upload-pack hook for statistics purposes.
-
-(developers)
-
- * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
- source directory; using tmpfs may give faster turnaround.
-
- * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
- build for one location, and install into another location to tar it
- up.

-Git v1.6.6.2 Release Notes
-==========================
-
-Fixes since v1.6.6.1
---------------------
-
- * recursive merge didn't correctly diagnose its own programming errors,
- and instead caused the caller to segfault.
-
- * The new "smart http" aware clients probed the web servers to see if
- they support smart http, but did not fall back to dumb http transport
- correctly with some servers.
-
- * Time based reflog syntax e.g. "@{yesterday}" didn't diagnose a misspelled
- time specification and instead assumed "@{now}".
-
- * "git archive HEAD -- no-such-directory" produced an empty archive
- without complaining.
-
- * "git blame -L start,end -- file" misbehaved when given a start that is
- larger than the number of lines in the file.
-
- * "git checkout -m" didn't correctly call custom merge backend supplied
- by the end user.
-
- * "git config -f <file>" misbehaved when run from a subdirectory.
-
- * "git cvsserver" didn't like having regex metacharacters (e.g. '+') in
- CVSROOT environment.
-
- * "git fast-import" did not correctly handle large blobs that may
- bust the pack size limit.
-
- * "git gui" is supposed to work even when launched from inside a .git
- directory.
-
- * "git gui" misbehaved when applying a hunk that ends with deletion.
-
- * "git imap-send" did not honor imap.preformattedHTML as documented.
-
- * "git log" family incorrectly showed the commit notes unconditionally by

-
- * "git status" shouldn't require an write access to the repository.

-Git v1.6.6 Release Notes
-========================
-
-Notes on behaviour change
--------------------------
-
- * In this release, "git fsck" defaults to "git fsck --full" and
- checks packfiles, and because of this it will take much longer to
- complete than before. If you prefer a quicker check only on loose
- objects (the old default), you can say "git fsck --no-full". This
- has been supported by 1.5.4 and newer versions of git, so it is
- safe to write it in your script even if you use slightly older git
- on some of your machines.
-
-Preparing yourselves for compatibility issues in 1.7.0
-------------------------------------------------------
-
-In git 1.7.0, which is planned to be the release after 1.6.6, there will
-be a handful of behaviour changes that will break backward compatibility.
-
-These changes were discussed long time ago and existing behaviours have
-been identified as more problematic to the userbase than keeping them for
-the sake of backward compatibility.
-
-When necessary, a transition strategy for existing users has been designed
-not to force them running around setting configuration variables and
-updating their scripts in order to either keep the traditional behaviour
-or adjust to the new behaviour, on the day their sysadmin decides to install
-the new version of git. When we switched from "git-foo" to "git foo" in
-1.6.0, even though the change had been advertised and the transition
-guide had been provided for a very long time, the users procrastinated
-during the entire transition period, and ended up panicking on the day
-their sysadmins updated their git installation. We are trying to avoid
-repeating that unpleasantness in the 1.7.0 release.
-
-For changes decided to be in 1.7.0, commands that will be affected
-have been much louder to strongly discourage such procrastination, and
-they continue to be in this release. If you have been using recent
-versions of git, you would have seen warnings issued when you used
-features whose behaviour will change, with a clear instruction on how
-to keep the existing behaviour if you want to. You hopefully are
-already well prepared.
-
-Of course, we have also been giving "this and that will change in
-1.7.0; prepare yourselves" warnings in the release notes and
-announcement messages for the past few releases. Let's see how well
-users will fare this time.
-
- * "git push" into a branch that is currently checked out (i.e. pointed by
- HEAD in a repository that is not bare) will be refused by default.
-
- Similarly, "git push $there :$killed" to delete the branch $killed
- in a remote repository $there, when $killed branch is the current
- branch pointed at by its HEAD, will be refused by default.
-
- Setting the configuration variables receive.denyCurrentBranch and
- receive.denyDeleteCurrent to 'ignore' in the receiving repository
- can be used to override these safety features. Versions of git
- since 1.6.2 have issued a loud warning when you tried to do these
- operations without setting the configuration, so repositories of
- people who still need to be able to perform such a push should
- already have been future proofed.
-
- Please refer to:
-
- http://git.or.cz/gitwiki/GitFaq#non-bare
- http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
-
- for more details on the reason why this change is needed and the
- transition process that already took place so far.
-
- * "git send-email" will not make deep threads by default when sending a
- patch series with more than two messages. All messages will be sent
- as a reply to the first message, i.e. cover letter. Git 1.6.6 (this
- release) will issue a warning about the upcoming default change, when
- it uses the traditional "deep threading" behaviour as the built-in
- default. To squelch the warning but still use the "deep threading"
- behaviour, give --chain-reply-to option or set sendemail.chainreplyto
- to true.
-
- It has been possible to configure send-email to send "shallow thread"
- by setting sendemail.chainreplyto configuration variable to false.
- The only thing 1.7.0 release will do is to change the default when
- you haven't configured that variable.
-
- * "git status" will not be "git commit --dry-run". This change does not
- affect you if you run the command without pathspec.
-
- Nobody sane found the current behaviour of "git status Makefile" useful
- nor meaningful, and it confused users. "git commit --dry-run" has been
- provided as a way to get the current behaviour of this command since
- 1.6.5.
-
- * "git diff" traditionally treated various "ignore whitespace" options
- only as a way to filter the patch output. "git diff --exit-code -b"
- exited with non-zero status even if all changes were about changing the
- amount of whitespace and nothing else. and "git diff -b" showed the
- "diff --git" header line for such a change without patch text.
-
- In 1.7.0, the "ignore whitespaces" will affect the semantics of the
- diff operation itself. A change that does not affect anything but
- whitespaces will be reported with zero exit status when run with
- --exit-code, and there will not be "diff --git" header for such a
- change.
-
-
-Updates since v1.6.5
---------------------
-
-(subsystems)
-
- * various gitk updates including use of themed widgets under Tk 8.5,
- Japanese translation, a fix to a bug when running "gui blame" from
- a subdirectory, etc.
-
- * various git-gui updates including new translations, wm states fixes,
- Tk bug workaround after quitting, improved heuristics to trigger gc,
- etc.
-
- * various git-svn updates.
-
- * "git fetch" over http learned a new mode that is different from the
- traditional "dumb commit walker".
-
-(portability)
-
- * imap-send can be built on mingw port.
-
-(performance)
-
- * "git diff -B" has smaller memory footprint.
-
-(usability, bells and whistles)
-
- * The object replace mechanism can be bypassed with --no-replace-objects
- global option given to the "git" program.
-
- * In configuration files, a few variables that name paths can begin with ~/
- and ~username/ and they are expanded as expected.
-
- * "git subcmd -h" now shows short usage help for many more subcommands.
-
- * "git bisect reset" can reset to an arbitrary commit.
-
- * "git checkout frotz" when there is no local branch "frotz" but there
- is only one remote tracking branch "frotz" is taken as a request to
- start the named branch at the corresponding remote tracking branch.
-
- * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
- to ignore authorship information in the commit it is taking the message
- from.
-
- * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
-
- * "git diff" learned --submodule option to show a list of one-line logs
- instead of differences between the commit object names.
-
- * "git diff" learned to honor diff.color.func configuration to paint
- function name hint printed on the hunk header "@@ -j,k +l,m @@" line
- in the specified color.
-
- * "git fetch" learned --all and --multiple options, to run fetch from
- many repositories, and --prune option to remove remote tracking
- branches that went stale. These make "git remote update" and "git
- remote prune" less necessary (there is no plan to remove "remote
- update" nor "remote prune", though).
-
- * "git fsck" by default checks the packfiles (i.e. "--full" is the
- default); you can turn it off with "git fsck --no-full".
-
- * "git grep" can use -F (fixed strings) and -i (ignore case) together.
-
- * import-tars contributed fast-import frontend learned more types of
- compressed tarballs.
-
- * "git instaweb" knows how to talk with mod_cgid to apache2.
-
- * "git log --decorate" shows the location of HEAD as well.
-
- * "git log" and "git rev-list" learned to take revs and pathspecs from
- the standard input with the new "--stdin" option.
-
- * "--pretty=format" option to "log" family of commands learned:
-
- . to wrap text with the "%w()" specifier.
- . to show reflog information with "%g[sdD]" specifier.
-
- * "git notes" command to annotate existing commits.
-
- * "git merge" (and "git pull") learned --ff-only option to make it fail
- if the merge does not result in a fast-forward.
-
- * "git mergetool" learned to use p4merge.
-
- * "git rebase -i" learned "reword" that acts like "edit" but immediately
- starts an editor to tweak the log message without returning control to
- the shell, which is done by "edit" to give an opportunity to tweak the
- contents.
-
- * "git send-email" can be told with "--envelope-sender=auto" to use the
- same address as "From:" address as the envelope sender address.
-
- * "git send-email" will issue a warning when it defaults to the
- --chain-reply-to behaviour without being told by the user and
- instructs to prepare for the change of the default in 1.7.0 release.
-
- * In "git submodule add <repository> <path>", <path> is now optional and
- inferred from <repository> the same way "git clone <repository>" does.
-
- * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
-
- * "git svn" learned to recreate empty directories tracked only by SVN.
-
- * "gitweb" can optionally render its "blame" output incrementally (this
- requires JavaScript on the client side).
-
- * Author names shown in gitweb output are links to search commits by the
- author.

-Fixes since v1.7.0

-
- * In a freshly created repository "rev-parse HEAD^0" complained that
- it is dangling symref, even though "rev-parse HEAD" didn't.
-
- * "git show :no-such-name" tried to access the index without bounds
- check, leading to a potential segfault.
-
- * Message from "git cherry-pick" was harder to read and use than necessary
- when it stopped due to conflicting changes.
-
- * We referred to ".git/refs/" throughout the documentation when we
- meant to talk about abstract notion of "ref namespace". Because
- people's repositories often have packed refs these days, this was
- confusing.
-
- * "git diff --output=/path/that/cannot/be/written" did not correctly
- error out.
-
- * "git grep -e -pattern-that-begin-with-dash paths..." could not be
- spelled as "git grep -- -pattern-that-begin-with-dash paths..." which
- would be a GNU way to use "--" as "end of options".

-Fixes since v1.7.0.1
---------------------
-
- * GIT_PAGER was not honored consistently by some scripted Porcelains, most
- notably "git am".
-
- * updating working tree files after telling git to add them to the
- index and while it is still working created garbage object files in
- the repository without diagnosing it as an error.
-
- * "git bisect -- pathspec..." did not diagnose an error condition properly when
- the simplification with given pathspec made the history empty.

- * "git rev-list --cherry-pick A...B" now has an obvious optimization when the
- histories haven't diverged (i.e. when one end is an ancestor of the other).

- * "git diff --quiet -w" did not work as expected.
-
- * "git fast-import" didn't work with a large input, as it lacked support
- for producing the pack index in v2 format.

- has been optimized for utf-8 payload.
-
- * Error messages generated on the receiving end did not come back to "git

-
- * "git add -i" didn't handle a deleted path very well.
-
- * "git blame" padded line numbers with one extra SP when the total number

-
- * "git fetch --all/--multi" used to discard information for remotes that
- are fetched earlier.

- * "git log -g branch" misbehaved when there was no entries in the reflog
- for the named branch.
-
- * "git mailinfo" (hence "git am") incorrectly removed initial indent from
- paragraphs.

-Git v1.7.0 Release Notes
-========================
-
-Notes on behaviour change
--------------------------
-
- * "git push" into a branch that is currently checked out (i.e. pointed at by
- HEAD in a repository that is not bare) is refused by default.
-
- Similarly, "git push $there :$killed" to delete the branch $killed
- in a remote repository $there, when $killed branch is the current
- branch pointed at by its HEAD, will be refused by default.
-
- Setting the configuration variables receive.denyCurrentBranch and
- receive.denyDeleteCurrent to 'ignore' in the receiving repository
- can be used to override these safety features.
-
- * "git send-email" does not make deep threads by default when sending a
- patch series with more than two messages. All messages will be sent
- as a reply to the first message, i.e. cover letter.
-
- It has been possible already to configure send-email to send "shallow thread"
- by setting sendemail.chainreplyto configuration variable to false. The
- only thing this release does is to change the default when you haven't
- configured that variable.
-
- * "git status" is not "git commit --dry-run" anymore. This change does
- not affect you if you run the command without argument.
-
- * "git diff" traditionally treated various "ignore whitespace" options
- only as a way to filter the patch output. "git diff --exit-code -b"
- exited with non-zero status even if all changes were about changing the
- amount of whitespace and nothing else; and "git diff -b" showed the
- "diff --git" header line for such a change without patch text.
-
- In this release, the "ignore whitespaces" options affect the semantics
- of the diff operation. A change that does not affect anything but
- whitespaces is reported with zero exit status when run with
- --exit-code, and there is no "diff --git" header for such a change.
-
- * External diff and textconv helpers are now executed using the shell.
- This makes them consistent with other programs executed by git, and
- allows you to pass command-line parameters to the helpers. Any helper
- paths containing spaces or other metacharacters now need to be
- shell-quoted. The affected helpers are GIT_EXTERNAL_DIFF in the
- environment, and diff.*.command and diff.*.textconv in the config
- file.
-
- * The --max-pack-size argument to 'git repack', 'git pack-objects', and
- 'git fast-import' was assuming the provided size to be expressed in MiB,
- unlike the corresponding config variable and other similar options accepting
- a size value. It is now expecting a size expressed in bytes, with a possible
- unit suffix of 'k', 'm', or 'g'.
-
-Updates since v1.6.6
---------------------
-
-(subsystems)
-
- * "git fast-import" updates; adds "option" and "feature" to detect the
- mismatch between fast-import and the frontends that produce the input
- stream.
-
- * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
-
- * "gitk" and "git gui" translation updates.
-
- * "gitweb" updates (code clean-up, load checking etc.)
-
-(portability)
-
- * Some more MSVC portability patches for msysgit port.
-
- * Minimum Pthreads emulation for msysgit port.
-
-(performance)
-
- * More performance improvement patches for msysgit port.
-
-(usability, bells and whistles)
-
- * More commands learned "--quiet" and "--[no-]progress" options.
-
- * Various commands given by the end user (e.g. diff.type.textconv,
- and GIT_EDITOR) can be specified with command line arguments. E.g. it
- is now possible to say "[diff "utf8doc"] textconv = nkf -w".
-
- * "sparse checkout" feature allows only part of the work tree to be
- checked out.
-
- * HTTP transfer can use authentication scheme other than basic
- (i.e./e.g. digest).
-
- * Switching from a version of superproject that used to have a submodule
- to another version of superproject that no longer has it did not remove
- the submodule directory when it should (namely, when you are not
- interested in the submodule at all and didn't clone/checkout).
-
- * A new attribute conflict-marker-size can be used to change the size of
- the conflict markers from the default 7; this is useful when tracked
- contents (e.g. git-merge documentation) have strings that resemble the
- conflict markers.
-
- * A new syntax "<branch>@{upstream}" can be used on the command line to
- substitute the name of the "upstream" of the branch. Missing branch
- defaults to the current branch, so "git fetch && git merge @{upstream}"
- will be equivalent to "git pull".
-
- * "git am --resolved" has a synonym "git am --continue".
-
- * "git branch --set-upstream" can be used to update the (surprise!) upstream,
- i.e. where the branch is supposed to pull and merge from (or rebase onto).
-
- * "git checkout A...B" is a way to detach HEAD at the merge base between
- A and B.
-
- * "git checkout -m path" to reset the work tree file back into the
- conflicted state works even when you already ran "git add path" and
- resolved the conflicts.
-
- * "git commit --date='<date>'" can be used to override the author date
- just like "git commit --author='<name> <email>'" can be used to
- override the author identity.
-
- * "git commit --no-status" can be used to omit the listing of the index
- and the work tree status in the editor used to prepare the log message.
-
- * "git commit" warns a bit more aggressively until you configure user.email,
- whose default value almost always is not (and fundamentally cannot be)
- what you want.
-
- * "git difftool" has been extended to make it easier to integrate it
- with gitk.
-
- * "git fetch --all" can now be used in place of "git remote update".
-
- * "git grep" does not rely on external grep anymore. It can use more than
- one thread to accelerate the operation.
-
- * "git grep" learned "--quiet" option.
-
- * "git log" and friends learned "--glob=heads/*" syntax that is a more
- flexible way to complement "--branches/--tags/--remotes".
-
- * "git merge" learned to pass options specific to strategy-backends. E.g.
-
- - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
- strategy how much to shift the trees explicitly.
-
- - "git merge -Xtheirs" can be used to auto-merge as much as possible,
- while discarding your own changes and taking merged version in
- conflicted regions.
-
- * "git push" learned "git push origin --delete branch", a syntactic sugar
- for "git push origin :branch".
-
- * "git push" learned "git push --set-upstream origin forker:forkee" that
- lets you configure your "forker" branch to later pull from "forkee"
- branch at "origin".
-
- * "git rebase --onto A...B" means the history is replayed on top of the
- merge base between A and B.
-
- * "git rebase -i" learned new action "fixup" that squashes the change
- but does not affect existing log message.
-
- * "git rebase -i" also learned --autosquash option that is useful
- together with the new "fixup" action.
-
- * "git remote" learned set-url subcommand that updates (surprise!) url
- for an existing remote nickname.
-
- * "git rerere" learned "forget path" subcommand. Together with "git
- checkout -m path" it will be useful when you recorded a wrong
- resolution.
-
- * Use of "git reset --merge" has become easier when resetting away a
- conflicted mess left in the work tree.
-
- * "git rerere" had rerere.autoupdate configuration but there was no way
- to countermand it from the command line; --no-rerere-autoupdate option
- given to "merge", "revert", etc. fixes this.
-
- * "git status" learned "-s(hort)" output format.
-
-(developers)
-
- * The infrastructure to build foreign SCM interface has been updated.
-
- * Many more commands are now built-in.
-
- * THREADED_DELTA_SEARCH is no more. If you build with threads, delta
- compression will always take advantage of it.
-
-Fixes since v1.6.6
-------------------
-
-All of the fixes in v1.6.6.X maintenance series are included in this
-release, unless otherwise noted.
-
- * "git branch -d branch" used to refuse deleting the branch even when
- the branch is fully merged to its upstream branch if it is not merged
- to the current branch. It now deletes it in such a case.
-
- * "filter-branch" command incorrectly said --prune-empty and --filter-commit
- were incompatible; the latter should be read as --commit-filter.
-
- * When using "git status" or asking "git diff" to compare the work tree
- with something, they used to consider that a checked-out submodule with
- uncommitted changes is not modified; this could cause people to forget
- committing these changes in the submodule before committing in the
- superproject. They now consider such a change as a modification and
- "git diff" will append a "-dirty" to the work tree side when generating
- patch output or when used with the --submodule option.

-Git v1.7.1.1 Release Notes
-==========================
-
-Fixes since v1.7.1
-------------------
-
- * Authentication over http transport can now be made lazily, in that the
- request can first go to a URL without username, get a 401 response and
- then the client will ask for the username to use.
-
- * We used to mistakenly think "../work" is a subdirectory of the current
- directory when we are in "../work-xyz".
-
- * The attribute mechanism now allows an entry that uses an attribute
- macro that set/unset one attribute, immediately followed by an
- overriding setting; this makes attribute macros much easier to use.
-
- * We didn't recognize timezone "Z" as a synonym for "UTC" (75b37e70).
-
- * In 1.7.0, read-tree and user commands that use the mechanism such as
- checkout and merge were fixed to handle switching between branches one
- of which has a file while the other has a directory at the same path
- correctly even when there are some "confusing" pathnames in them. But
- the algorithm used for this fix was suboptimal and had a terrible
- performance degradation especially in larger trees.
-
- * "git am -3" did not show diagnosis when the patch in the message was corrupt.
-
- * After "git apply --whitespace=fix" removed trailing blank lines in an
- patch in a patch series, it failed to apply later patches that depend
- on the presence of such blank lines.
-
- * "git bundle --stdin" segfaulted.
-
- * "git checkout" and "git rebase" overwrote paths that are marked "assume
- unchanged".
-
- * "git commit --amend" on a commit with an invalid author-name line that
- lacks the display name didn't work.
-
- * "git describe" did not tie-break tags that point at the same commit
- correctly; newer ones are preferred by paying attention to the
- tagger date now.
-
- * "git diff" used to tell underlying xdiff machinery to work very hard to
- minimize the output, but this often was spending too many extra cycles
- for very little gain.
-
- * "git diff --color" did not paint extended diff headers per line
- (i.e. the coloring escape sequence didn't end at the end of line),
- which confused "less -R".
-
- * "git fetch" over HTTP verifies the downloaded packfiles more robustly.
-
- * The memory usage by "git index-pack" (run during "git fetch" and "git
- push") got leaner.
-
- * "GIT_DIR=foo.git git init --bare bar.git" created foo.git instead of bar.git.
-
- * "git log --abbrev=$num --format='%h' ignored --abbrev=$num.
-
- * "git ls-files ../out/side/cwd" refused to work.
-
- * "git merge --log" used to replace the custom message given by "-m" with
- the shortlog, instead of appending to it.
-
- * "git notes copy" without any other argument segfaulted.
-
- * "git pull" accepted "--dry-run", gave it to underlying "git fetch" but
- ignored the option itself, resulting in a bogus attempt to merge
- unrelated commit.
-
- * "git rebase" did not faithfully reproduce a malformed author ident, that
- is often seen in a repository converted from foreign SCMs.
-
- * "git reset --hard" started from a wrong directory and a working tree in
- a nonstandard location is in use got confused.
-
- * "git send-email" lacked a way to specify the domainname used in the
- EHLO/HELO exchange, causing rejected connection from picky servers.
- It learned --smtp-domain option to solve this issue.
-
- * "git send-email" did not declare a content-transfer-encoding and
- content-type even when its payload needs to be sent in 8-bit.
-
- * "git show -C -C" and other corner cases lost diff metainfo output
- in 1.7.0.
-
- * "git stash" incorrectly lost paths in the working tree that were
- previously removed from the index.
-
- * "git status" stopped refreshing the index by mistake in 1.7.1.
-
- * "git status" showed excess "hints" even when advice.statusHints is set to false.
-
-And other minor fixes and documentation updates.

-
-Fixes since v1.7.1.1
---------------------
-
- * "git commit" did not honor GIT_REFLOG_ACTION environment variable, resulting
- reflog messages for cherry-pick and revert actions to be recorded as "commit".
-
- * "git clone/fetch/pull" issued an incorrect error message when a ref and
- a symref that points to the ref were updated at the same time. This
- obviously would update them to the same value, and should not result in
- an error condition.
-
- * "git diff" inside a tree with many pathnames that have certain
- characters has become very slow in 1.7.0 by mistake.
-
- * "git rev-parse --parseopt --stop-at-non-option" did not stop at non option
- when --keep-dashdash was in effect.
-
- * An overlong line after ".gitdir: " in a git file caused out of bounds
- access to an array on the stack.

- * When people try insane things such as delta-compressing 4GiB files, we
- threw an assertion failure.
-
- * "git archive" gave the full commit ID for "$Format:%h$".
-
- * "git fetch --tags" did not fetch tags when remote.<nick>.tagopt was set
- to --no-tags. The command line option now overrides the configuration
- setting.
-
- * "git for-each-ref --format='%(objectname:short)'" has been completely
- broken for a long time.
-
- * "git gc" incorrectly pruned a rerere record that was created long
- time ago but still is actively and repeatedly used.

- forcing the user to dismiss it.
-
- * "git rebase" did not work well when the user has diff.renames
- configuration variable set.

-Updates since v1.7.1
---------------------
-
- * core.eol configuration and text/eol attributes are the new way to control
- the end of line conventions for files in the working tree.
-
- * core.autocrlf has been made safer - it will now only handle line
- endings for new files and files that are LF-only in the
- repository. To normalize content that has been checked in with
- CRLF, use the new eol/text attributes.
-
- * The whitespace rules used in "git apply --whitespace" and "git diff"
- gained a new member in the family (tab-in-indent) to help projects with
- policy to indent only with spaces.
-
- * When working from a subdirectory, by default, git does not look for its
- metadirectory ".git" across filesystems, primarily to help people who
- have invocations of git in their custom PS1 prompts, as being outside
- of a git repository would look for ".git" all the way up to the root
- directory, and NFS mounts are often slow. DISCOVERY_ACROSS_FILESYSTEM
- environment variable can be used to tell git not to stop at a
- filesystem boundary.
-
- * Usage help messages generated by parse-options library (i.e. most
- of the Porcelain commands) are sent to the standard output now.
-
- * ':/<string>' notation to look for a commit now takes regular expression
- and it is not anchored at the beginning of the commit log message
- anymore (this is a backward incompatible change).
-
- * "git" wrapper learned "-c name=value" option to override configuration
- variable from the command line.
-
- * Improved portability for various platforms including older SunOS,
- HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
-
- * The message from "git am -3" has been improved when conflict
- resolution ended up making the patch a no-op.
-
- * "git blame" applies the textconv filter to the contents it works
- on, when available.
-
- * "git checkout --orphan newbranch" is similar to "-b newbranch" but
- prepares to create a root commit that is not connected to any existing
- commit.
-
- * "git cherry-pick" learned to pick a range of commits
- (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
- revert"; these do not support the nicer sequencing control "rebase
- [-i]" has, though.
-
- * "git cherry-pick" and "git revert" learned --strategy option to specify
- the merge strategy to be used when performing three-way merges.
-
- * "git cvsserver" can be told to use pserver; its password file can be
- stored outside the repository.
-
- * The output from the textconv filter used by "git diff" can be cached to
- speed up their reuse.
-
- * "git diff --word-diff=<mode>" extends the existing "--color-words"
- option, making it more useful in color-challenged environments.
-
- * The regexp to detect function headers used by "git diff" for PHP has
- been enhanced for visibility modifiers (public, protected, etc.) to
- better support PHP5.
-
- * "diff.noprefix" configuration variable can be used to implicitly
- ask for "diff --no-prefix" behaviour.
-
- * "git for-each-ref" learned "%(objectname:short)" that gives the object
- name abbreviated.
-
- * "git format-patch" learned --signature option and format.signature
- configuration variable to customize the e-mail signature used in the
- output.
-
- * Various options to "git grep" (e.g. --count, --name-only) work better
- with binary files.
-
- * "git grep" learned "-Ovi" to open the files with hits in your editor.
-
- * "git help -w" learned "chrome" and "chromium" browsers.
-
- * "git log --decorate" shows commit decorations in various colours.
-
- * "git log --follow <path>" follows across copies (it used to only follow
- renames). This may make the processing more expensive.
-
- * "git log --pretty=format:<template>" specifier learned "% <something>"
- magic that inserts a space only when %<something> expands to a
- non-empty string; this is similar to "%+<something>" magic, but is
- useful in a context to generate a single line output.
-
- * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
- what "git prune" has.
-
- * "git patch-id" can be fed a mbox without getting confused by the
- signature line in the format-patch output.
-
- * "git remote" learned "set-branches" subcommand.
-
- * "git rev-list A..B" learned --ancestry-path option to further limit
- the result to the commits that are on the ancestry chain between A and
- B (i.e. commits that are not descendants of A are excluded).
-
- * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
- to the update to make "git show master..next" walk the history,
- introduced in 1.6.4.
-
- * "git status [-s] --ignored" can be used to list ignored paths.
-
- * "git status -s -b" shows the current branch in the output.
-
- * "git status" learned "--ignore-submodules" option.
-
- * Various "gitweb" enhancements and clean-ups, including syntax
- highlighting, "plackup" support for instaweb, .fcgi suffix to run
- it as FastCGI script, etc.
-
- * The test harness has been updated to produce TAP-friendly output.
-
- * Many documentation improvement patches are also included.
-
-
-Fixes since v1.7.1
-------------------
-
-All of the fixes in v1.7.1.X maintenance series are included in this
-release, unless otherwise noted.
-
- * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
- had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
-
- * "git clone" did not configure remote.origin.url correctly for bare
- clones (df61c889).
-
- * "git diff --graph" works better with "--color-words" and other options
- (81fa024..4297c0a).
-
- * "git diff" could show ambiguous abbreviation of blob object names on
- its "index" line (3e5a188).
-
- * "git reset --hard" started from a wrong directory and a working tree in
- a nonstandard location is in use got confused (560fb6a1).
-
- * "git read-tree -m A B" used to switch to branch B while retaining
- local changes added an incorrect cache-tree information (b1f47514).

+GIT v1.5.0.1 Release Notes
+==========================
+
+Fixes since v1.5.0
+------------------
+
+* Documentation updates
+
+ - Clarifications and corrections to 1.5.0 release notes.
+
+ - The main documentation did not link to git-remote documentation.
+
+ - Clarified introductory text of git-rebase documentation.
+
+ - Converted remaining mentions of update-index on Porcelain
+ documents to git-add/git-rm.
+
+ - Some i18n.* configuration variables were incorrectly
+ described as core.*; fixed.
+
+* Bugfixes
+
+ - git-add and git-update-index on a filesystem on which
+ executable bits are unreliable incorrectly reused st_mode
+ bits even when the path changed between symlink and regular
+ file.
+
+ - git-daemon marks the listening sockets with FD_CLOEXEC so
+ that it won't be leaked into the children.
+
+ - segfault from git-blame when the mandatory pathname
+ parameter was missing was fixed; usage() message is given
+ instead.
+
+ - git-rev-list did not read $GIT_DIR/config file, which means
+ that did not honor i18n.logoutputencoding correctly.
+
+* Tweaks
+
+ - sliding mmap() inefficiently mmaped the same region of a
+ packfile with an access pattern that used objects in the
+ reverse order. This has been made more efficient.
--- /dev/null
+GIT v1.5.0.2 Release Notes
+==========================
+
+Fixes since v1.5.0.1
+--------------------
+
+* Bugfixes
+
+ - Automated merge conflict handling when changes to symbolic
+ links conflicted were completely broken. The merge-resolve
+ strategy created a regular file with conflict markers in it
+ in place of the symbolic link. The default strategy,
+ merge-recursive was even more broken. It removed the path
+ that was pointed at by the symbolic link. Both of these
+ problems have been fixed.
+
+ - 'git diff maint master next' did not correctly give combined
+ diff across three trees.
+
+ - 'git fast-import' portability fix for Solaris.
+
+ - 'git show-ref --verify' without arguments did not error out
+ but segfaulted.
+
+ - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
+ slashes after a/ and b/.
+
+ - 'git format-patch' produced too long filenames if the commit
+ message had too long line at the beginning.
+
+ - Running 'make all' and then without changing anything
+ running 'make install' still rebuilt some files. This
+ was inconvenient when building as yourself and then
+ installing as root (especially problematic when the source
+ directory is on NFS and root is mapped to nobody).
+
+ - 'git-rerere' failed to deal with two unconflicted paths that
+ sorted next to each other.
+
+ - 'git-rerere' attempted to open(2) a symlink and failed if
+ there was a conflict. Since a conflicting change to a
+ symlink would not benefit from rerere anyway, the command
+ now ignores conflicting changes to symlinks.
+
+ - 'git-repack' did not like to pass more than 64 arguments
+ internally to underlying 'rev-list' logic, which made it
+ impossible to repack after accumulating many (small) packs
+ in the repository.
+
+ - 'git-diff' to review the combined diff during a conflicted
+ merge were not reading the working tree version correctly
+ when changes to a symbolic link conflicted. It should have
+ read the data using readlink(2) but read from the regular
+ file the symbolic link pointed at.
+
+ - 'git-remote' did not like period in a remote's name.
+
+* Documentation updates
+
+ - added and clarified core.bare, core.legacyheaders configurations.
+
+ - updated "git-clone --depth" documentation.
+
+
+* Assorted git-gui fixes.

+GIT v1.5.0.3 Release Notes
+==========================
+
+Fixes since v1.5.0.2
+--------------------
+
+* Bugfixes
+
+ - 'git.el' honors the commit coding system from the configuration.
+
+ - 'blameview' in contrib/ correctly digs deeper when a line is
+ clicked.
+
+ - 'http-push' correctly makes sure the remote side has leading
+ path. Earlier it started in the middle of the path, and
+ incorrectly.
+
+ - 'git-merge' did not exit with non-zero status when the
+ working tree was dirty and cannot fast forward. It does
+ now.
+
+ - 'cvsexportcommit' does not lose yet-to-be-used message file.
+
+ - int-vs-size_t typefix when running combined diff on files
+ over 2GB long.
+
+ - 'git apply --whitespace=strip' should not touch unmodified
+ lines.
+
+ - 'git-mailinfo' choke when a logical header line was too long.
+
+ - 'git show A..B' did not error out. Negative ref ("not A" in
+ this example) does not make sense for the purpose of the
+ command, so now it errors out.
+
+ - 'git fmt-merge-msg --file' without file parameter did not
+ correctly error out.
+
+ - 'git archimport' barfed upon encountering a commit without
+ summary.
+
+ - 'git index-pack' did not protect itself from getting a short
+ read out of pread(2).
+
+ - 'git http-push' had a few buffer overruns.
+
+ - Build dependency fixes to rebuild fetch.o when other headers
+ change.
+
+* Documentation updates
+
+ - user-manual updates.
+
+ - Options to 'git remote add' were described insufficiently.
+
+ - Configuration format.suffix was not documented.
+
+ - Other formatting and spelling fixes.

+GIT v1.5.0 Release Notes
+========================
+
+Old news
+--------
+
+This section is for people who are upgrading from ancient
+versions of git. Although all of the changes in this section
+happened before the current v1.4.4 release, they are summarized
+here in the v1.5.0 release notes for people who skipped earlier
+versions.
+
+As of git v1.5.0 there are some optional features that changes
+the repository to allow data to be stored and transferred more
+efficiently. These features are not enabled by default, as they
+will make the repository unusable with older versions of git.
+Specifically, the available options are:
+
+ - There is a configuration variable core.legacyheaders that
+ changes the format of loose objects so that they are more
+ efficient to pack and to send out of the repository over git
+ native protocol, since v1.4.2. However, loose objects
+ written in the new format cannot be read by git older than
+ that version; people fetching from your repository using
+ older clients over dumb transports (e.g. http) using older
+ versions of git will also be affected.
+
+ To let git use the new loose object format, you have to
+ set core.legacyheaders to false.
+
+ - Since v1.4.3, configuration repack.usedeltabaseoffset allows
+ packfile to be created in more space efficient format, which
+ cannot be read by git older than that version.
+
+ To let git use the new format for packfiles, you have to
+ set repack.usedeltabaseoffset to true.
+
+The above two new features are not enabled by default and you
+have to explicitly ask for them, because they make repositories
+unreadable by older versions of git, and in v1.5.0 we still do
+not enable them by default for the same reason. We will change
+this default probably 1 year after 1.4.2's release, when it is
+reasonable to expect everybody to have new enough version of
+git.
+
+ - 'git pack-refs' appeared in v1.4.4; this command allows tags
+ to be accessed much more efficiently than the traditional
+ 'one-file-per-tag' format. Older git-native clients can
+ still fetch from a repository that packed and pruned refs
+ (the server side needs to run the up-to-date version of git),
+ but older dumb transports cannot. Packing of refs is done by
+ an explicit user action, either by use of "git pack-refs
+ --prune" command or by use of "git gc" command.
+
+ - 'git -p' to paginate anything -- many commands do pagination
+ by default on a tty. Introduced between v1.4.1 and v1.4.2;
+ this may surprise old timers.
+
+ - 'git archive' superseded 'git tar-tree' in v1.4.3;
+
+ - 'git cvsserver' was new invention in v1.3.0;
+
+ - 'git repo-config', 'git grep', 'git rebase' and 'gitk' were
+ seriously enhanced during v1.4.0 timeperiod.
+
+ - 'gitweb' became part of git.git during v1.4.0 timeperiod and
+ seriously modified since then.
+
+ - reflog is an v1.4.0 invention. This allows you to name a
+ revision that a branch used to be at (e.g. "git diff
+ master@{yesterday} master" allows you to see changes since
+ yesterday's tip of the branch).
+
+
+Updates in v1.5.0 since v1.4.4 series
+-------------------------------------
+
+* Index manipulation
+
+ - git-add is to add contents to the index (aka "staging area"
+ for the next commit), whether the file the contents happen to
+ be is an existing one or a newly created one.
+
+ - git-add without any argument does not add everything
+ anymore. Use 'git-add .' instead. Also you can add
+ otherwise ignored files with an -f option.
+
+ - git-add tries to be more friendly to users by offering an
+ interactive mode ("git-add -i").
+
+ - git-commit <path> used to refuse to commit if <path> was
+ different between HEAD and the index (i.e. update-index was
+ used on it earlier). This check was removed.
+
+ - git-rm is much saner and safer. It is used to remove paths
+ from both the index file and the working tree, and makes sure
+ you are not losing any local modification before doing so.
+
+ - git-reset <tree> <paths>... can be used to revert index
+ entries for selected paths.
+
+ - git-update-index is much less visible. Many suggestions to
+ use the command in git output and documentation have now been
+ replaced by simpler commands such as "git add" or "git rm".
+
+
+* Repository layout and objects transfer
+
+ - The data for origin repository is stored in the configuration
+ file $GIT_DIR/config, not in $GIT_DIR/remotes/, for newly
+ created clones. The latter is still supported and there is
+ no need to convert your existing repository if you are
+ already comfortable with your workflow with the layout.
+
+ - git-clone always uses what is known as "separate remote"
+ layout for a newly created repository with a working tree.
+
+ A repository with the separate remote layout starts with only
+ one default branch, 'master', to be used for your own
+ development. Unlike the traditional layout that copied all
+ the upstream branches into your branch namespace (while
+ renaming their 'master' to your 'origin'), the new layout
+ puts upstream branches into local "remote-tracking branches"
+ with their own namespace. These can be referenced with names
+ such as "origin/$upstream_branch_name" and are stored in
+ .git/refs/remotes rather than .git/refs/heads where normal
+ branches are stored.
+
+ This layout keeps your own branch namespace less cluttered,
+ avoids name collision with your upstream, makes it possible
+ to automatically track new branches created at the remote
+ after you clone from it, and makes it easier to interact with
+ more than one remote repository (you can use "git remote" to
+ add other repositories to track). There might be some
+ surprises:
+
+ * 'git branch' does not show the remote tracking branches.
+ It only lists your own branches. Use '-r' option to view
+ the tracking branches.
+
+ * If you are forking off of a branch obtained from the
+ upstream, you would have done something like 'git branch
+ my-next next', because traditional layout dropped the
+ tracking branch 'next' into your own branch namespace.
+ With the separate remote layout, you say 'git branch next
+ origin/next', which allows you to use the matching name
+ 'next' for your own branch. It also allows you to track a
+ remote other than 'origin' (i.e. where you initially cloned
+ from) and fork off of a branch from there the same way
+ (e.g. "git branch mingw j6t/master").
+
+ Repositories initialized with the traditional layout continue
+ to work.
+
+ - New branches that appear on the origin side after a clone is
+ made are also tracked automatically. This is done with an
+ wildcard refspec "refs/heads/*:refs/remotes/origin/*", which
+ older git does not understand, so if you clone with 1.5.0,
+ you would need to downgrade remote.*.fetch in the
+ configuration file to specify each branch you are interested
+ in individually if you plan to fetch into the repository with
+ older versions of git (but why would you?).
+
+ - Similarly, wildcard refspec "refs/heads/*:refs/remotes/me/*"
+ can be given to "git-push" command to update the tracking
+ branches that is used to track the repository you are pushing
+ from on the remote side.
+
+ - git-branch and git-show-branch know remote tracking branches
+ (use the command line switch "-r" to list only tracked branches).
+
+ - git-push can now be used to delete a remote branch or a tag.
+ This requires the updated git on the remote side (use "git
+ push <remote> :refs/heads/<branch>" to delete "branch").
+
+ - git-push more aggressively keeps the transferred objects
+ packed. Earlier we recommended to monitor amount of loose
+ objects and repack regularly, but you should repack when you
+ accumulated too many small packs this way as well. Updated
+ git-count-objects helps you with this.
+
+ - git-fetch also more aggressively keeps the transferred objects
+ packed. This behavior of git-push and git-fetch can be
+ tweaked with a single configuration transfer.unpacklimit (but
+ usually there should not be any need for a user to tweak it).
+
+ - A new command, git-remote, can help you manage your remote
+ tracking branch definitions.
+
+ - You may need to specify explicit paths for upload-pack and/or
+ receive-pack due to your ssh daemon configuration on the
+ other end. This can now be done via remote.*.uploadpack and
+ remote.*.receivepack configuration.
+
+
+* Bare repositories
+
+ - Certain commands change their behavior in a bare repository
+ (i.e. a repository without associated working tree). We use
+ a fairly conservative heuristic (if $GIT_DIR is ".git", or
+ ends with "/.git", the repository is not bare) to decide if a
+ repository is bare, but "core.bare" configuration variable
+ can be used to override the heuristic when it misidentifies
+ your repository.
+
+ - git-fetch used to complain updating the current branch but
+ this is now allowed for a bare repository. So is the use of
+ 'git-branch -f' to update the current branch.
+
+ - Porcelain-ish commands that require a working tree refuses to
+ work in a bare repository.
+
+
+* Reflog
+
+ - Reflog records the history from the view point of the local
+ repository. In other words, regardless of the real history,
+ the reflog shows the history as seen by one particular
+ repository (this enables you to ask "what was the current
+ revision in _this_ repository, yesterday at 1pm?"). This
+ facility is enabled by default for repositories with working
+ trees, and can be accessed with the "branch@{time}" and
+ "branch@{Nth}" notation.
+
+ - "git show-branch" learned showing the reflog data with the
+ new -g option. "git log" has -g option to view reflog
+ entries in a more verbose manner.
+
+ - git-branch knows how to rename branches and moves existing
+ reflog data from the old branch to the new one.
+
+ - In addition to the reflog support in v1.4.4 series, HEAD
+ reference maintains its own log. "HEAD@{5.minutes.ago}"
+ means the commit you were at 5 minutes ago, which takes
+ branch switching into account. If you want to know where the
+ tip of your current branch was at 5 minutes ago, you need to
+ explicitly say its name (e.g. "master@{5.minutes.ago}") or
+ omit the refname altogether i.e. "@{5.minutes.ago}".
+
+ - The commits referred to by reflog entries are now protected
+ against pruning. The new command "git reflog expire" can be
+ used to truncate older reflog entries and entries that refer
+ to commits that have been pruned away previously with older
+ versions of git.
+
+ Existing repositories that have been using reflog may get
+ complaints from fsck-objects and may not be able to run
+ git-repack, if you had run git-prune from older git; please
+ run "git reflog expire --stale-fix --all" first to remove
+ reflog entries that refer to commits that are no longer in
+ the repository when that happens.
+
+
+* Crufts removal
+
+ - We used to say "old commits are retrievable using reflog and
+ 'master@{yesterday}' syntax as long as you haven't run
+ git-prune". We no longer have to say the latter half of the
+ above sentence, as git-prune does not remove things reachable
+ from reflog entries.
+
+ - There is a toplevel garbage collector script, 'git-gc', that
+ runs periodic cleanup functions, including 'git-repack -a -d',
+ 'git-reflog expire', 'git-pack-refs --prune', and 'git-rerere
+ gc'.
+
+ - The output from fsck ("fsck-objects" is called just "fsck"
+ now, but the old name continues to work) was needlessly
+ alarming in that it warned missing objects that are reachable
+ only from dangling objects. This has been corrected and the
+ output is much more useful.
+
+
+* Detached HEAD
+
+ - You can use 'git-checkout' to check out an arbitrary revision
+ or a tag as well, instead of named branches. This will
+ dissociate your HEAD from the branch you are currently on.
+
+ A typical use of this feature is to "look around". E.g.
+
+ $ git checkout v2.6.16
+ ... compile, test, etc.
+ $ git checkout v2.6.17
+ ... compile, test, etc.
+
+ - After detaching your HEAD, you can go back to an existing
+ branch with usual "git checkout $branch". Also you can
+ start a new branch using "git checkout -b $newbranch" to
+ start a new branch at that commit.
+
+ - You can even pull from other repositories, make merges and
+ commits while your HEAD is detached. Also you can use "git
+ reset" to jump to arbitrary commit, while still keeping your
+ HEAD detached.
+
+ Remember that a detached state is volatile, i.e. it will be forgotten
+ as soon as you move away from it with the checkout or reset command,
+ unless a branch is created from it as mentioned above. It is also
+ possible to rescue a lost detached state from the HEAD reflog.
+
+
+* Packed refs
+
+ - Repositories with hundreds of tags have been paying large
+ overhead, both in storage and in runtime, due to the
+ traditional one-ref-per-file format. A new command,
+ git-pack-refs, can be used to "pack" them in more efficient
+ representation (you can let git-gc do this for you).
+
+ - Clones and fetches over dumb transports are now aware of
+ packed refs and can download from repositories that use
+ them.
+
+
+* Configuration
+
+ - configuration related to color setting are consolidated under
+ color.* namespace (older diff.color.*, status.color.* are
+ still supported).
+
+ - 'git-repo-config' command is accessible as 'git-config' now.
+
+
+* Updated features
+
+ - git-describe uses better criteria to pick a base ref. It
+ used to pick the one with the newest timestamp, but now it
+ picks the one that is topologically the closest (that is,
+ among ancestors of commit C, the ref T that has the shortest
+ output from "git-rev-list T..C" is chosen).
+
+ - git-describe gives the number of commits since the base ref
+ between the refname and the hash suffix. E.g. the commit one
+ before v2.6.20-rc6 in the kernel repository is:
+
+ v2.6.20-rc5-306-ga21b069
+
+ which tells you that its object name begins with a21b069,
+ v2.6.20-rc5 is an ancestor of it (meaning, the commit
+ contains everything -rc5 has), and there are 306 commits
+ since v2.6.20-rc5.
+
+ - git-describe with --abbrev=0 can be used to show only the
+ name of the base ref.
+
+ - git-blame learned a new option, --incremental, that tells it
+ to output the blames as they are assigned. A sample script
+ to use it is also included as contrib/blameview.
+
+ - git-blame starts annotating from the working tree by default.
+
+
+* Less external dependency
+
+ - We no longer require the "merge" program from the RCS suite.
+ All 3-way file-level merges are now done internally.
+
+ - The original implementation of git-merge-recursive which was
+ in Python has been removed; we have a C implementation of it
+ now.
+
+ - git-shortlog is no longer a Perl script. It no longer
+ requires output piped from git-log; it can accept revision
+ parameters directly on the command line.
+
+
+* I18n
+
+ - We have always encouraged the commit message to be encoded in
+ UTF-8, but the users are allowed to use legacy encoding as
+ appropriate for their projects. This will continue to be the
+ case. However, a non UTF-8 commit encoding _must_ be
+ explicitly set with i18n.commitencoding in the repository
+ where a commit is made; otherwise git-commit-tree will
+ complain if the log message does not look like a valid UTF-8
+ string.
+
+ - The value of i18n.commitencoding in the originating
+ repository is recorded in the commit object on the "encoding"
+ header, if it is not UTF-8. git-log and friends notice this,
+ and reencodes the message to the log output encoding when
+ displaying, if they are different. The log output encoding
+ is determined by "git log --encoding=<encoding>",
+ i18n.logoutputencoding configuration, or i18n.commitencoding
+ configuration, in the decreasing order of preference, and
+ defaults to UTF-8.
+
+ - Tools for e-mailed patch application now default to -u
+ behavior; i.e. it always re-codes from the e-mailed encoding
+ to the encoding specified with i18n.commitencoding. This
+ unfortunately forces projects that have happily been using a
+ legacy encoding without setting i18n.commitencoding to set
+ the configuration, but taken with other improvement, please
+ excuse us for this very minor one-time inconvenience.
+
+
+* e-mailed patches
+
+ - See the above I18n section.
+
+ - git-format-patch now enables --binary without being asked.
+ git-am does _not_ default to it, as sending binary patch via
+ e-mail is unusual and is harder to review than textual
+ patches and it is prudent to require the person who is
+ applying the patch to explicitly ask for it.
+
+ - The default suffix for git-format-patch output is now ".patch",
+ not ".txt". This can be changed with --suffix=.txt option,
+ or setting the config variable "format.suffix" to ".txt".
+
+
+* Foreign SCM interfaces
+
+ - git-svn now requires the Perl SVN:: libraries, the
+ command-line backend was too slow and limited.
+
+ - the 'commit' subcommand of git-svn has been renamed to
+ 'set-tree', and 'dcommit' is the recommended replacement for
+ day-to-day work.
+
+ - git fast-import backend.
+
+
+* User support
+
+ - Quite a lot of documentation updates.
+
+ - Bash completion scripts have been updated heavily.
+
+ - Better error messages for often used Porcelainish commands.
+
+ - Git GUI. This is a simple Tk based graphical interface for
+ common Git operations.
+
+
+* Sliding mmap
+
+ - We used to assume that we can mmap the whole packfile while
+ in use, but with a large project this consumes huge virtual
+ memory space and truly huge ones would not fit in the
+ userland address space on 32-bit platforms. We now mmap huge
+ packfile in pieces to avoid this problem.
+
+
+* Shallow clones
+
+ - There is a partial support for 'shallow' repositories that
+ keeps only recent history. A 'shallow clone' is created by
+ specifying how deep that truncated history should be
+ (e.g. "git clone --depth 5 git://some.where/repo.git").
+
+ Currently a shallow repository has number of limitations:
+
+ - Cloning and fetching _from_ a shallow clone are not
+ supported (nor tested -- so they might work by accident but
+ they are not expected to).
+
+ - Pushing from nor into a shallow clone are not expected to
+ work.
+
+ - Merging inside a shallow repository would work as long as a
+ merge base is found in the recent history, but otherwise it
+ will be like merging unrelated histories and may result in
+ huge conflicts.
+
+ but this would be more than adequate for people who want to
+ look at near the tip of a big project with a deep history and
+ send patches in e-mail format.

+GIT v1.5.1.1 Release Notes
+==========================
+
+Fixes since v1.5.1
+------------------
+
+* Documentation updates
+
+ - The --left-right option of rev-list and friends is documented.
+
+ - The documentation for cvsimport has been majorly improved.
+
+ - "git-show-ref --exclude-existing" was documented.
+
+* Bugfixes
+
+ - The implementation of -p option in "git cvsexportcommit" had
+ the meaning of -C (context reduction) option wrong, and
+ loosened the context requirements when it was told to be
+ strict.
+
+ - "git cvsserver" did not behave like the real cvsserver when
+ client side removed a file from the working tree without
+ doing anything else on the path. In such a case, it should
+ restore it from the checked out revision.
+
+ - "git fsck" issued an alarming error message on detached
+ HEAD. It is not an error since at least 1.5.0.
+
+ - "git send-email" produced of References header of unbounded length;
+ fixed this with line-folding.
+
+ - "git archive" to download from remote site should not
+ require you to be in a git repository, but it incorrectly
+ did.
+
+ - "git apply" ignored -p<n> for "diff --git" formatted
+ patches.
+
+ - "git rerere" recorded a conflict that had one side empty
+ (the other side adds) incorrectly; this made merging in the
+ other direction fail to use previously recorded resolution.
+
+ - t4200 test was broken where "wc -l" pads its output with
+ spaces.
+
+ - "git branch -m old new" to rename branch did not work
+ without a configuration file in ".git/config".
+
+ - The sample hook for notification e-mail was misnamed.
+
+ - gitweb did not show type-changing patch correctly in the
+ blobdiff view.
+
+ - git-svn did not error out with incorrect command line options.
+
+ - git-svn fell into an infinite loop when insanely long commit
+ message was found.
+
+ - git-svn dcommit and rebase was confused by patches that were
+ merged from another branch that is managed by git-svn.
+
+ - git-svn used to get confused when globbing remote branch/tag
+ spec (e.g. "branches = proj/branches/*:refs/remotes/origin/*")
+ is used and there was a plain file that matched the glob.
--- /dev/null
+GIT v1.5.1.2 Release Notes
+==========================
+
+Fixes since v1.5.1.1
+--------------------
+
+* Bugfixes
+
+ - "git clone" over http from a repository that has lost the
+ loose refs by running "git pack-refs" were broken (a code to
+ deal with this was added to "git fetch" in v1.5.0, but it
+ was missing from "git clone").
+
+ - "git diff a/ b/" incorrectly fell in "diff between two
+ filesystem objects" codepath, when the user most likely
+ wanted to limit the extent of output to two tracked
+ directories.
+
+ - git-quiltimport had the same bug as we fixed for
+ git-applymbox in v1.5.1.1 -- it gave an alarming "did not
+ have any patch" message (but did not actually fail and was
+ harmless).
+
+ - various git-svn fixes.
+
+ - Sample update hook incorrectly always refused requests to
+ delete branches through push.
+
+ - git-blame on a very long working tree path had buffer
+ overrun problem.
+
+ - git-apply did not like to be fed two patches in a row that created
+ and then modified the same file.
+
+ - git-svn was confused when a non-project was stored directly under
+ trunk/, branches/ and tags/.
+
+ - git-svn wants the Error.pm module that was at least as new
+ as what we ship as part of git; install ours in our private
+ installation location if the one on the system is older.
+
+ - An earlier update to command line integer parameter parser was
+ botched and made 'update-index --cacheinfo' completely useless.
+
+
+* Documentation updates
+
+ - Various documentation updates from J. Bruce Fields, Frank
+ Lichtenheld, Alex Riesen and others. Andrew Ruder started a
+ war on undocumented options.
--- /dev/null
+GIT v1.5.1.3 Release Notes
+==========================
+
+Fixes since v1.5.1.2
+--------------------
+
+* Bugfixes
+
+ - git-add tried to optimize by finding common leading
+ directories across its arguments but botched, causing very
+ confused behaviour.
+
+ - unofficial rpm.spec file shipped with git was letting
+ ETC_GITCONFIG set to /usr/etc/gitconfig. Tweak the official
+ Makefile to make it harder for distro people to make the
+ same mistake, by setting the variable to /etc/gitconfig if
+ prefix is set to /usr.
+
+ - git-svn inconsistently stripped away username from the URL
+ only when svnsync_props was in use.
+
+ - git-svn got confused when handling symlinks on Mac OS.
+
+ - git-send-email was not quoting recipient names that have
+ period '.' in them. Also it did not allow overriding
+ envelope sender, which made it impossible to send patches to
+ certain subscriber-only lists.
+
+ - built-in write_tree() routine had a sequence that renamed a
+ file that is still open, which some systems did not like.
+
+ - when memory is very tight, sliding mmap code to read
+ packfiles incorrectly closed the fd that was still being
+ used to read the pack.
+
+ - import-tars contributed front-end for fastimport was passing
+ wrong directory modes without checking.
+
+ - git-fastimport trusted its input too much and allowed to
+ create corrupt tree objects with entries without a name.
+
+ - git-fetch needlessly barfed when too long reflog action
+ description was given by the caller.
+
+Also contains various documentation updates.
--- /dev/null
+GIT v1.5.1.4 Release Notes
+==========================
+
+Fixes since v1.5.1.3
+--------------------
+
+* Bugfixes
+
+ - "git-http-fetch" did not work around a bug in libcurl
+ earlier than 7.16 (curl_multi_remove_handle() was broken).
+
+ - "git cvsserver" handles a file that was once removed and
+ then added again correctly.
+
+ - import-tars script (in contrib/) handles GNU tar archives
+ that contain pathnames longer than 100 bytes (long-link
+ extension) correctly.
+
+ - xdelta test program did not build correctly.
+
+ - gitweb sometimes tried incorrectly to apply function to
+ decode utf8 twice, resulting in corrupt output.
+
+ - "git blame -C" mishandled text at the end of a group of
+ lines.
+
+ - "git log/rev-list --boundary" did not produce output
+ correctly without --left-right option.
+
+ - Many documentation updates.
--- /dev/null
+GIT v1.5.1.5 Release Notes
+==========================
+
+Fixes since v1.5.1.4
+--------------------
+
+* Bugfixes
+
+ - git-send-email did not understand aliases file for mutt, which
+ allows leading whitespaces.
+
+ - git-format-patch emitted Content-Type and Content-Transfer-Encoding
+ headers for non ASCII contents, but failed to add MIME-Version.
+
+ - git-name-rev had a buffer overrun with a deep history.
+
+ - contributed script import-tars did not get the directory in
+ tar archives interpreted correctly.
+
+ - git-svn was reported to segfault for many people on list and
+ #git; hopefully this has been fixed.
+
+ - "git-svn clone" does not try to minimize the URL
+ (i.e. connect to higher level hierarchy) by default, as this
+ can prevent clone to fail if only part of the repository
+ (e.g. 'trunk') is open to public.
+
+ - "git checkout branch^0" did not detach the head when you are
+ already on 'branch'; backported the fix from the 'master'.
+
+ - "git-config section.var" did not correctly work when
+ existing configuration file had both [section] and [section "name"]
+ next to each other.
+
+ - "git clone ../other-directory" was fooled if the current
+ directory $PWD points at is a symbolic link.
+
+ - (build) tree_entry_extract() function was both static inline
+ and extern, which caused trouble compiling with Forte12
+ compilers on Sun.
+
+ - Many many documentation fixes and updates.

+
+ - "git-svn clone" does not try to minimize the URL

--- /dev/null
+GIT v1.5.1 Release Notes
+========================
+
+Updates since v1.5.0
+--------------------
+
+* Deprecated commands and options.
+
+ - git-diff-stages and git-resolve have been removed.
+
+* New commands and options.
+
+ - "git log" and friends take --reverse, which instructs them
+ to give their output in the order opposite from their usual.
+ They typically output from new to old, but with this option
+ their output would read from old to new. "git shortlog"
+ usually lists older commits first, but with this option,
+ they are shown from new to old.
+
+ - "git log --pretty=format:<string>" to allow more flexible
+ custom log output.
+
+ - "git diff" learned --ignore-space-at-eol. This is a weaker
+ form of --ignore-space-change.
+
+ - "git diff --no-index pathA pathB" can be used as diff
+ replacement with git specific enhancements.
+
+ - "git diff --no-index" can read from '-' (standard input).
+
+ - "git diff" also learned --exit-code to exit with non-zero
+ status when it found differences. In the future we might
+ want to make this the default but that would be a rather big
+ backward incompatible change; it will stay as an option for
+ now.
+
+ - "git diff --quiet" is --exit-code with output turned off,
+ meant for scripted use to quickly determine if there is any
+ tree-level difference.
+
+ - Textual patch generation with "git diff" without -w/-b
+ option has been significantly optimized. "git blame" got
+ faster because of the same change.
+
+ - "git log" and "git rev-list" has been optimized
+ significantly when they are used with pathspecs.
+
+ - "git branch --track" can be used to set up configuration
+ variables to help it easier to base your work on branches
+ you track from a remote site.
+
+ - "git format-patch --attach" now emits attachments. Use
+ --inline to get an inlined multipart/mixed.
+
+ - "git name-rev" learned --refs=<pattern>, to limit the tags
+ used for naming the given revisions only to the ones
+ matching the given pattern.
+
+ - "git remote update" is to run "git fetch" for defined remotes
+ to update tracking branches.
+
+ - "git cvsimport" can now take '-d' to talk with a CVS
+ repository different from what are recorded in CVS/Root
+ (overriding it with environment CVSROOT does not work).
+
+ - "git bundle" can help sneaker-netting your changes between
+ repositories.
+
+ - "git mergetool" can help 3-way file-level conflict
+ resolution with your favorite graphical merge tools.
+
+ - A new configuration "core.symlinks" can be used to disable
+ symlinks on filesystems that do not support them; they are
+ checked out as regular files instead.
+
+ - You can name a commit object with its first line of the
+ message. The syntax to use is ':/message text'. E.g.
+
+ $ git show ":/object name: introduce ':/<oneline prefix>' notation"
+
+ means the same thing as:
+
+ $ git show 28a4d940443806412effa246ecc7768a21553ec7
+
+ - "git bisect" learned a new command "run" that takes a script
+ to run after each revision is checked out to determine if it
+ is good or bad, to automate the bisection process.
+
+ - "git log" family learned a new traversal option --first-parent,
+ which does what the name suggests.
+
+
+* Updated behavior of existing commands.
+
+ - "git-merge-recursive" used to barf when there are more than
+ one common ancestors for the merge, and merging them had a
+ rename/rename conflict. This has been fixed.
+
+ - "git fsck" does not barf on corrupt loose objects.
+
+ - "git rm" does not remove newly added files without -f.
+
+ - "git archimport" allows remapping when coming up with git
+ branch names from arch names.
+
+ - git-svn got almost a rewrite.
+
+ - core.autocrlf configuration, when set to 'true', makes git
+ to convert CRLF at the end of lines in text files to LF when
+ reading from the filesystem, and convert in reverse when
+ writing to the filesystem. The variable can be set to
+ 'input', in which case the conversion happens only while
+ reading from the filesystem but files are written out with
+ LF at the end of lines. Currently, which paths to consider
+ 'text' (i.e. be subjected to the autocrlf mechanism) is
+ decided purely based on the contents, but the plan is to
+ allow users to explicitly override this heuristic based on
+ paths.
+
+ - The behavior of 'git-apply', when run in a subdirectory,
+ without --index nor --cached were inconsistent with that of
+ the command with these options. This was fixed to match the
+ behavior with --index. A patch that is meant to be applied
+ with -p1 from the toplevel of the project tree can be
+ applied with any custom -p<n> option. A patch that is not
+ relative to the toplevel needs to be applied with -p<n>
+ option with or without --index (or --cached).
+
+ - "git diff" outputs a trailing HT when pathnames have embedded
+ SP on +++/--- header lines, in order to help "GNU patch" to
+ parse its output. "git apply" was already updated to accept
+ this modified output format since ce74618d (Sep 22, 2006).
+
+ - "git cvsserver" runs hooks/update and honors its exit status.
+
+ - "git cvsserver" can be told to send everything with -kb.
+
+ - "git diff --check" also honors the --color output option.
+
+ - "git name-rev" used to stress the fact that a ref is a tag too
+ much, by saying something like "v1.2.3^0~22". It now says
+ "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
+ not talk about an ancestor of the commit that is tagged, which
+ makes sense).
+
+ - "git rev-list --boundary" now shows boundary markers for the
+ commits omitted by --max-age and --max-count condition.
+
+ - The configuration mechanism now reads $(prefix)/etc/gitconfig.
+
+ - "git apply --verbose" shows what preimage lines were wanted
+ when it couldn't find them.
+
+ - "git status" in a read-only repository got a bit saner.
+
+ - "git fetch" (hence "git clone" and "git pull") are less
+ noisy when the output does not go to tty.
+
+ - "git fetch" between repositories with many refs were slow
+ even when there are not many changes that needed
+ transferring. This has been sped up by partially rewriting
+ the heaviest parts in C.
+
+ - "git mailinfo" which splits an e-mail into a patch and the
+ meta-information was rewritten, thanks to Don Zickus. It
+ handles nested multipart better. The command was broken for
+ a brief period on 'master' branch since 1.5.0 but the
+ breakage is fixed now.
+
+ - send-email learned configurable bcc and chain-reply-to.
+
+ - "git remote show $remote" also talks about branches that
+ would be pushed if you run "git push remote".
+
+ - Using objects from packs is now seriously optimized by clever
+ use of a cache. This should be most noticeable in git-log
+ family of commands that involve reading many tree objects.
+ In addition, traversing revisions while filtering changes
+ with pathspecs is made faster by terminating the comparison
+ between the trees as early as possible.
+
+
+* Hooks
+
+ - The part to send out notification e-mails was removed from
+ the sample update hook, as it was not an appropriate place
+ to do so. The proper place to do this is the new post-receive
+ hook. An example hook has been added to contrib/hooks/.
+
+
+* Others
+
+ - git-revert, git-gc and git-cherry-pick are now built-ins.
+
+Fixes since v1.5.0
+------------------
+
+These are all in v1.5.0.x series.
+
+* Documentation updates
+
+ - Clarifications and corrections to 1.5.0 release notes.
+
+ - The main documentation did not link to git-remote documentation.
+
+ - Clarified introductory text of git-rebase documentation.
+
+ - Converted remaining mentions of update-index on Porcelain
+ documents to git-add/git-rm.
+
+ - Some i18n.* configuration variables were incorrectly
+ described as core.*; fixed.
+
+ - added and clarified core.bare, core.legacyheaders configurations.
+
+ - updated "git-clone --depth" documentation.
+
+ - user-manual updates.
+
+ - Options to 'git remote add' were described insufficiently.
+
+ - Configuration format.suffix was not documented.
+
+ - Other formatting and spelling fixes.
+
+ - user-manual has better cross references.
+
+ - gitweb installation/deployment procedure is now documented.
+
+
+* Bugfixes
+
+ - git-upload-pack closes unused pipe ends; earlier this caused
+ many zombies to hang around.
+
+ - git-rerere was recording the contents of earlier hunks
+ duplicated in later hunks. This prevented resolving the same
+ conflict when performing the same merge the other way around.
+
+ - git-add and git-update-index on a filesystem on which
+ executable bits are unreliable incorrectly reused st_mode
+ bits even when the path changed between symlink and regular
+ file.
+
+ - git-daemon marks the listening sockets with FD_CLOEXEC so
+ that it won't be leaked into the children.
+
+ - segfault from git-blame when the mandatory pathname
+ parameter was missing was fixed; usage() message is given
+ instead.
+
+ - git-rev-list did not read $GIT_DIR/config file, which means
+ that did not honor i18n.logoutputencoding correctly.
+
+ - Automated merge conflict handling when changes to symbolic
+ links conflicted were completely broken. The merge-resolve
+ strategy created a regular file with conflict markers in it
+ in place of the symbolic link. The default strategy,
+ merge-recursive was even more broken. It removed the path
+ that was pointed at by the symbolic link. Both of these
+ problems have been fixed.
+
+ - 'git diff maint master next' did not correctly give combined
+ diff across three trees.
+
+ - 'git fast-import' portability fix for Solaris.
+
+ - 'git show-ref --verify' without arguments did not error out
+ but segfaulted.
+
+ - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
+ slashes after a/ and b/.
+
+ - 'git format-patch' produced too long filenames if the commit
+ message had too long line at the beginning.
+
+ - Running 'make all' and then without changing anything
+ running 'make install' still rebuilt some files. This
+ was inconvenient when building as yourself and then
+ installing as root (especially problematic when the source
+ directory is on NFS and root is mapped to nobody).
+
+ - 'git-rerere' failed to deal with two unconflicted paths that
+ sorted next to each other.
+
+ - 'git-rerere' attempted to open(2) a symlink and failed if
+ there was a conflict. Since a conflicting change to a
+ symlink would not benefit from rerere anyway, the command
+ now ignores conflicting changes to symlinks.
+
+ - 'git-repack' did not like to pass more than 64 arguments
+ internally to underlying 'rev-list' logic, which made it
+ impossible to repack after accumulating many (small) packs
+ in the repository.
+
+ - 'git-diff' to review the combined diff during a conflicted
+ merge were not reading the working tree version correctly
+ when changes to a symbolic link conflicted. It should have
+ read the data using readlink(2) but read from the regular
+ file the symbolic link pointed at.
+
+ - 'git-remote' did not like period in a remote's name.
+
+ - 'git.el' honors the commit coding system from the configuration.
+
+ - 'blameview' in contrib/ correctly digs deeper when a line is
+ clicked.
+
+ - 'http-push' correctly makes sure the remote side has leading
+ path. Earlier it started in the middle of the path, and
+ incorrectly.
+
+ - 'git-merge' did not exit with non-zero status when the
+ working tree was dirty and cannot fast forward. It does
+ now.
+
+ - 'cvsexportcommit' does not lose yet-to-be-used message file.
+
+ - int-vs-size_t typefix when running combined diff on files
+ over 2GB long.
+
+ - 'git apply --whitespace=strip' should not touch unmodified
+ lines.
+
+ - 'git-mailinfo' choke when a logical header line was too long.
+
+ - 'git show A..B' did not error out. Negative ref ("not A" in
+ this example) does not make sense for the purpose of the
+ command, so now it errors out.
+
+ - 'git fmt-merge-msg --file' without file parameter did not
+ correctly error out.
+
+ - 'git archimport' barfed upon encountering a commit without
+ summary.
+
+ - 'git index-pack' did not protect itself from getting a short
+ read out of pread(2).
+
+ - 'git http-push' had a few buffer overruns.
+
+ - Build dependency fixes to rebuild fetch.o when other headers
+ change.
+
+ - git.el does not add duplicate sign-off lines.
+
+ - git-commit shows the full stat of the resulting commit, not
+ just about the files in the current directory, when run from
+ a subdirectory.
+
+ - "git-checkout -m '@{8 hours ago}'" had a funny failure from
+ eval; fixed.
+
+ - git-merge (hence git-pull) did not refuse fast-forwarding
+ when the working tree had local changes that would have
+ conflicted with it.
+
+ - a handful small fixes to gitweb.
+
+ - build procedure for user-manual is fixed not to require locally
+ installed stylesheets.
+
+ - "git commit $paths" on paths whose earlier contents were
+ already updated in the index were failing out.
+
+
+* Tweaks
+
+ - sliding mmap() inefficiently mmaped the same region of a
+ packfile with an access pattern that used objects in the
+ reverse order. This has been made more efficient.

+
+* Bugfixes
+
+ - Temporary files that are used when invoking external diff
+ programs did not tolerate a long TMPDIR.
+
+ - git-daemon did not notice when it could not write into its
+ pid file.
+
+ - git-status did not honor core.excludesFile configuration like
+ git-add did.
+
+ - git-annotate did not work from a subdirectory while
+ git-blame did.
+
+ - git-cvsserver should have disabled access to a repository
+ with "gitcvs.pserver.enabled = false" set even when
+ "gitcvs.enabled = true" was set at the same time. It
+ didn't.
+
+ - git-cvsimport did not work correctly in a repository with
+ its branch heads were packed with pack-refs.
+
+ - ident unexpansion to squash "$Id: xxx $" that is in the
+ repository copy removed incorrect number of bytes.
+
+ - git-svn misbehaved when the subversion repository did not
+ provide MD5 checksums for files.
+
+ - git rebase (and git am) misbehaved on commits that have '\n'
+ (literally backslash and en, not a linefeed) in the title.
+
+ - code to decode base85 used in binary patches had one error
+ return codepath wrong.
+
+ - RFC2047 Q encoding output by git-format-patch used '_' for a
+ space, which is not understood by some programs. It uses =20
+ which is safer.
+
+ - git-fastimport --import-marks was broken; fixed.
+
+ - A lot of documentation updates, clarifications and fixes.

+GIT v1.5.2.2 Release Notes
+==========================
+
+Fixes since v1.5.2.1
+--------------------
+
+* Usability fix
+
+ - git-gui is shipped with its updated blame interface. It is
+ rumored that the older one was not just unusable but was
+ active health hazard, but this one is actually pretty.
+ Please see for yourself.
+
+* Bugfixes
+
+ - "git checkout fubar" was utterly confused when there is a
+ branch fubar and a tag fubar at the same time. It correctly
+ checks out the branch fubar now.
+
+ - "git clone /path/foo" to clone a local /path/foo.git
+ repository left an incorrect configuration.
+
+ - "git send-email" correctly unquotes RFC 2047 quoted names in
+ the patch-email before using their values.
+
+ - We did not accept number of seconds since epoch older than
+ year 2000 as a valid timestamp. We now interpret positive
+ integers more than 8 digits as such, which allows us to
+ express timestamps more recent than March 1973.
+
+ - git-cvsimport did not work when you have GIT_DIR to point
+ your repository at a nonstandard location.
+
+ - Some systems (notably, Solaris) lack hstrerror() to make
+ h_errno human readable; prepare a replacement
+ implementation.
+
+ - .gitignore file listed git-core.spec but what we generate is
+ git.spec, and nobody noticed for a long time.
+
+ - "git-merge-recursive" does not try to run file level merge
+ on binary files.
+
+ - "git-branch --track" did not create tracking configuration
+ correctly when the branch name had slash in it.
+
+ - The email address of the user specified with user.email
+ configuration was overridden by EMAIL environment variable.
+
+ - The tree parser did not warn about tree entries with
+ nonsense file modes, and assumed they must be blobs.
+
+ - "git log -z" without any other request to generate diff still
+ invoked the diff machinery, wasting cycles.
+
+* Documentation
+
+ - Many updates to fix stale or missing documentation.
+
+ - Although our documentation was primarily meant to be formatted
+ with AsciiDoc7, formatting with AsciiDoc8 is supported better.

+GIT v1.5.2.3 Release Notes
+==========================
+
+Fixes since v1.5.2.2
+--------------------
+
+ * Bugfixes
+
+ - Version 2 pack index format was introduced in version 1.5.2
+ to support pack files that has offset that cannot be
+ represented in 32-bit. The runtime code to validate such
+ an index mishandled such an index for an empty pack.
+
+ - Commit walkers (most notably, fetch over http protocol)
+ tried to traverse commit objects contained in trees (aka
+ subproject); they shouldn't.
+
+ - A build option NO_R_TO_GCC_LINKER was not explained in Makefile
+ comment correctly.
+
+ * Documentation Fixes and Updates
+
+ - git-config --regexp was not documented properly.
+
+ - git-repack -a was not documented properly.
+
+ - git-remote -n was not documented properly.
--- /dev/null
+GIT v1.5.2.4 Release Notes
+==========================
+
+Fixes since v1.5.2.3
+--------------------
+
+ * Bugfixes
+
+ - "git-gui" bugfixes, including a handful fixes to run it
+ better on Cygwin/MSYS.
+
+ - "git checkout" failed to switch back and forth between
+ branches, one of which has "frotz -> xyzzy" symlink and
+ file "xyzzy/filfre", while the other one has a file
+ "frotz/filfre".
+
+ - "git prune" used to segfault upon seeing a commit that is
+ referred to by a tree object (aka "subproject").
+
+ - "git diff --name-status --no-index" mishandled an added file.
+
+ - "git apply --reverse --whitespace=warn" still complained
+ about whitespaces that a forward application would have
+ introduced.
+
+ * Documentation Fixes and Updates
+
+ - A handful documentation updates.
--- /dev/null
+GIT v1.5.2.5 Release Notes
+==========================
+
+Fixes since v1.5.2.4
+--------------------
+
+ * Bugfixes
+
+ - "git add -u" had a serious data corruption problem in one
+ special case (when the changes to a subdirectory's files
+ consist only deletion of files).
+
+ - "git add -u <path>" did not work from a subdirectory.
+
+ - "git apply" left an empty directory after all its files are
+ renamed away.
+
+ - "git $anycmd foo/bar", when there is a file 'foo' in the
+ working tree, complained that "git $anycmd foo/bar --" form
+ should be used to disambiguate between revs and files,
+ which was completely bogus.
+
+ - "git checkout-index" and other commands that checks out
+ files to the work tree tried unlink(2) on directories,
+ which is a sane thing to do on sane systems, but not on
+ Solaris when you are root.
+
+ * Documentation Fixes and Updates
+
+ - A handful documentation fixes.
--- /dev/null
+GIT v1.5.2 Release Notes
+========================
+
+Updates since v1.5.1
+--------------------
+
+* Plumbing level superproject support.
+
+ You can include a subdirectory that has an independent git
+ repository in your index and tree objects of your project
+ ("superproject"). This plumbing (i.e. "core") level
+ superproject support explicitly excludes recursive behaviour.
+
+ The "subproject" entries in the index and trees of a superproject
+ are incompatible with older versions of git. Experimenting with
+ the plumbing level support is encouraged, but be warned that
+ unless everybody in your project updates to this release or
+ later, using this feature would make your project
+ inaccessible by people with older versions of git.
+
+* Plumbing level gitattributes support.
+
+ The gitattributes mechanism allows you to add 'attributes' to
+ paths in your project, and affect the way certain git
+ operations work. Currently you can influence if a path is
+ considered a binary or text (the former would be treated by
+ 'git diff' not to produce textual output; the latter can go
+ through the line endings conversion process in repositories
+ with core.autocrlf set), expand and unexpand '$Id$' keyword
+ with blob object name, specify a custom 3-way merge driver,
+ and specify a custom diff driver. You can also apply
+ arbitrary filter to contents on check-in/check-out codepath
+ but this feature is an extremely sharp-edged razor and needs
+ to be handled with caution (do not use it unless you
+ understand the earlier mailing list discussion on keyword
+ expansion). These conversions apply when checking files in
+ or out, and exporting via git-archive.
+
+* The packfile format now optionally supports 64-bit index.
+
+ This release supports the "version 2" format of the .idx
+ file. This is automatically enabled when a huge packfile
+ needs more than 32-bit to express offsets of objects in the
+ pack.
+
+* Comes with an updated git-gui 0.7.1
+
+* Updated gitweb:
+
+ - can show combined diff for merges;
+ - uses font size of user's preference, not hardcoded in pixels;
+ - can now 'grep';
+
+* New commands and options.
+
+ - "git bisect start" can optionally take a single bad commit and
+ zero or more good commits on the command line.
+
+ - "git shortlog" can optionally be told to wrap its output.
+
+ - "subtree" merge strategy allows another project to be merged in as
+ your subdirectory.
+
+ - "git format-patch" learned a new --subject-prefix=<string>
+ option, to override the built-in "[PATCH]".
+
+ - "git add -u" is a quick way to do the first stage of "git
+ commit -a" (i.e. update the index to match the working
+ tree); it obviously does not make a commit.
+
+ - "git clean" honors a new configuration, "clean.requireforce". When
+ set to true, this makes "git clean" a no-op, preventing you
+ from losing files by typing "git clean" when you meant to
+ say "make clean". You can still say "git clean -f" to
+ override this.
+
+ - "git log" family of commands learned --date={local,relative,default}
+ option. --date=relative is synonym to the --relative-date.
+ --date=local gives the timestamp in local timezone.
+
+* Updated behavior of existing commands.
+
+ - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
+ but $EMAIL is set, the latter is used as a substitute.
+
+ - "git diff --stat" shows size of preimage and postimage blobs
+ for binary contents. Earlier it only said "Bin".
+
+ - "git lost-found" shows stuff that are unreachable except
+ from reflogs.
+
+ - "git checkout branch^0" now detaches HEAD at the tip commit
+ on the named branch, instead of just switching to the
+ branch (use "git checkout branch" to switch to the branch,
+ as before).
+
+ - "git bisect next" can be used after giving only a bad commit
+ without giving a good one (this starts bisection half-way to
+ the root commit). We used to refuse to operate without a
+ good and a bad commit.
+
+ - "git push", when pushing into more than one repository, does
+ not stop at the first error.
+
+ - "git archive" does not insist you to give --format parameter
+ anymore; it defaults to "tar".
+
+ - "git cvsserver" can use backends other than sqlite.
+
+ - "gitview" (in contrib/ section) learned to better support
+ "git-annotate".
+
+ - "git diff $commit1:$path2 $commit2:$path2" can now report
+ mode changes between the two blobs.
+
+ - Local "git fetch" from a repository whose object store is
+ one of the alternates (e.g. fetching from the origin in a
+ repository created with "git clone -l -s") avoids
+ downloading objects unnecessarily.
+
+ - "git blame" uses .mailmap to canonicalize the author name
+ just like "git shortlog" does.
+
+ - "git pack-objects" pays attention to pack.depth
+ configuration variable.
+
+ - "git cherry-pick" and "git revert" does not use .msg file in
+ the working tree to prepare commit message; instead it uses
+ $GIT_DIR/MERGE_MSG as other commands do.
+
+* Builds
+
+ - git-p4import has never been installed; now there is an
+ installation option to do so.
+
+ - gitk and git-gui can be configured out.
+
+ - Generated documentation pages automatically get version
+ information from GIT_VERSION.
+
+ - Parallel build with "make -j" descending into subdirectory
+ was fixed.
+
+* Performance Tweaks
+
+ - Optimized "git-rev-list --bisect" (hence "git-bisect").
+
+ - Optimized "git-add $path" in a large directory, most of
+ whose contents are ignored.
+
+ - Optimized "git-diff-tree" for reduced memory footprint.
+
+ - The recursive merge strategy updated a worktree file that
+ was changed identically in two branches, when one of them
+ renamed it. We do not do that when there is no rename, so
+ match that behaviour. This avoids excessive rebuilds.
+
+ - The default pack depth has been increased to 50, as the
+ recent addition of delta_base_cache makes deeper delta chains
+ much less expensive to access. Depending on the project, it was
+ reported that this reduces the resulting pack file by 10%
+ or so.
+
+
+Fixes since v1.5.1
+------------------
+
+All of the fixes in v1.5.1 maintenance series are included in
+this release, unless otherwise noted.
+
+* Bugfixes
+
+ - Switching branches with "git checkout" refused to work when
+ a path changes from a file to a directory between the
+ current branch and the new branch, in order not to lose
+ possible local changes in the directory that is being turned
+ into a file with the switch. We now allow such a branch
+ switch after making sure that there is no locally modified
+ file nor un-ignored file in the directory. This has not
+ been backported to 1.5.1.x series, as it is rather an
+ intrusive change.
+
+ - Merging branches that have a file in one and a directory in
+ another at the same path used to get quite confused. We
+ handle such a case a bit more carefully, even though that is
+ still left as a conflict for the user to sort out. This
+ will not be backported to 1.5.1.x series, as it is rather an
+ intrusive change.
+
+ - git-fetch had trouble with a remote with insanely large number
+ of refs.
+
+ - "git clean -d -X" now does not remove non-excluded directories.
+
+ - rebasing (without -m) a series that changes a symlink to a directory
+ in the middle of a path confused git-apply greatly and refused to
+ operate.

+GIT v1.5.3.1 Release Notes
+==========================
+
+Fixes since v1.5.3
+------------------
+
+This is solely to fix the generated RPM's dependencies. We used
+to have git-p4 package but we do not anymore. As suggested on
+the mailing list, this release makes git-core "Obsolete" git-p4,
+so that yum update would not complain.
--- /dev/null
+GIT v1.5.3.2 Release Notes
+==========================
+
+Fixes since v1.5.3.1
+--------------------
+
+ * git-push sent thin packs by default, which was not good for
+ the public distribution server (no point in saving transfer
+ while pushing; no point in making the resulting pack less
+ optimum).
+
+ * git-svn sometimes terminated with "Malformed network data" when
+ talking over svn:// protocol.
+
+ * git-send-email re-issued the same message-id about 10% of the
+ time if you fired off 30 messages within a single second.
+
+ * git-stash was not terminating the log message of commits it
+ internally creates with LF.
+
+ * git-apply failed to check the size of the patch hunk when its
+ beginning part matched the remainder of the preimage exactly,
+ even though the preimage recorded in the hunk was much larger
+ (therefore the patch should not have applied), leading to a
+ segfault.
+
+ * "git rm foo && git commit foo" complained that 'foo' needs to
+ be added first, instead of committing the removal, which was a
+ nonsense.
+
+ * git grep -c said "/dev/null: 0".
+
+ * git-add -u failed to recognize a blob whose type changed
+ between the index and the work tree.
+
+ * The limit to rename detection has been tightened a lot to
+ reduce performance problems with a huge change.
+
+ * cvsimport and svnimport barfed when the input tried to move
+ a tag.
+
+ * "git apply -pN" did not chop the right number of directories.
+
+ * "git svnimport" did not like SVN tags with funny characters in them.
+
+ * git-gui 0.8.3, with assorted fixes, including:
+
+ - font-chooser on X11 was unusable with large number of fonts;
+ - a diff that contained a deleted symlink made it barf;
+ - an untracked symbolic link to a directory made it fart;
+ - a file with % in its name made it vomit;
+
+
+Documentation updates
+---------------------
+
+User manual has been somewhat restructured. I think the new
+organization is much easier to read.
--- /dev/null
+GIT v1.5.3.3 Release Notes
+==========================
+
+Fixes since v1.5.3.2
+--------------------
+
+ * git-quiltimport did not like it when a patch described in the
+ series file does not exist.
+
+ * p4 importer missed executable bit in some cases.
+
+ * The default shell on some FreeBSD did not execute the
+ argument parsing code correctly and made git unusable.
+
+ * git-svn incorrectly spawned pager even when the user
+ explicitly asked not to.
+
+ * sample post-receive hook overquoted the envelope sender
+ value.
+
+ * git-am got confused when the patch contained a change that is
+ only about type and not contents.
+
+ * git-mergetool did not show our and their version of the
+ conflicted file when started from a subdirectory of the
+ project.
+
+ * git-mergetool did not pass correct options when invoking diff3.
+
+ * git-log sometimes invoked underlying "diff" machinery
+ unnecessarily.
--- /dev/null
+GIT v1.5.3.4 Release Notes
+==========================
+
+Fixes since v1.5.3.3
+--------------------
+
+ * Change to "git-ls-files" in v1.5.3.3 that was introduced to support
+ partial commit of removal better had a segfaulting bug, which was
+ diagnosed and fixed by Keith and Carl.
+
+ * Performance improvements for rename detection has been backported
+ from the 'master' branch.
+
+ * "git-for-each-ref --format='%(numparent)'" was not working
+ correctly at all, and --format='%(parent)' was not working for
+ merge commits.
+
+ * Sample "post-receive-hook" incorrectly sent out push
+ notification e-mails marked as "From: " the committer of the
+ commit that happened to be at the tip of the branch that was
+ pushed, not from the person who pushed.
+
+ * "git-remote" did not exit non-zero status upon error.
+
+ * "git-add -i" did not respond very well to EOF from tty nor
+ bogus input.
+
+ * "git-rebase -i" squash subcommand incorrectly made the
+ author of later commit the author of resulting commit,
+ instead of taking from the first one in the squashed series.
+
+ * "git-stash apply --index" was not documented.
+
+ * autoconfiguration learned that "ar" command is found as "gas" on
+ some systems.
--- /dev/null
+GIT v1.5.3.5 Release Notes
+==========================
+
+Fixes since v1.5.3.4
+--------------------
+
+ * Comes with git-gui 0.8.4.
+
+ * "git-config" silently ignored options after --list; now it will
+ error out with a usage message.
+
+ * "git-config --file" failed if the argument used a relative path
+ as it changed directories before opening the file.
+
+ * "git-config --file" now displays a proper error message if it
+ cannot read the file specified on the command line.
+
+ * "git-config", "git-diff", "git-apply" failed if run from a
+ subdirectory with relative GIT_DIR and GIT_WORK_TREE set.
+
+ * "git-blame" crashed if run during a merge conflict.
+
+ * "git-add -i" did not handle single line hunks correctly.
+
+ * "git-rebase -i" and "git-stash apply" failed if external diff
+ drivers were used for one or more files in a commit. They now
+ avoid calling the external diff drivers.
+
+ * "git-log --follow" did not work unless diff generation (e.g. -p)
+ was also requested.
+
+ * "git-log --follow -B" did not work at all. Fixed.
+
+ * "git-log -M -B" did not correctly handle cases of very large files
+ being renamed and replaced by very small files in the same commit.
+
+ * "git-log" printed extra newlines between commits when a diff
+ was generated internally (e.g. -S or --follow) but not displayed.
+
+ * "git-push" error message is more helpful when pushing to a
+ repository with no matching refs and none specified.
+
+ * "git-push" now respects + (force push) on wildcard refspecs,
+ matching the behavior of git-fetch.
+
+ * "git-filter-branch" now updates the working directory when it
+ has finished filtering the current branch.
+
+ * "git-instaweb" no longer fails on Mac OS X.
+
+ * "git-cvsexportcommit" didn't always create new parent directories
+ before trying to create new child directories. Fixed.
+
+ * "git-fetch" printed a scary (but bogus) error message while
+ fetching a tag that pointed to a tree or blob. The error did
+ not impact correctness, only user perception. The bogus error
+ is no longer printed.
+
+ * "git-ls-files --ignored" did not properly descend into non-ignored
+ directories that themselves contained ignored files if d_type
+ was not supported by the filesystem. This bug impacted systems
+ such as AFS. Fixed.
+
+ * Git segfaulted when reading an invalid .gitattributes file. Fixed.
+
+ * post-receive-email example hook was fixed for non-fast-forward
+ updates.
+
+ * Documentation updates for supported (but previously undocumented)
+ options of "git-archive" and "git-reflog".
+
+ * "make clean" no longer deletes the configure script that ships
+ with the git tarball, making multiple architecture builds easier.
+
+ * "git-remote show origin" spewed a warning message from Perl
+ when no remote is defined for the current branch via
+ branch.<name>.remote configuration settings.
+
+ * Building with NO_PERL_MAKEMAKER excessively rebuilt contents
+ of perl/ subdirectory by rewriting perl.mak.
+
+ * http.sslVerify configuration settings were not used in scripted
+ Porcelains.
+
+ * "git-add" leaked a bit of memory while scanning for files to add.
+
+ * A few workarounds to squelch false warnings from recent gcc have
+ been added.
+
+ * "git-send-pack $remote frotz" segfaulted when there is nothing
+ named 'frotz' on the local end.
+
+ * "git-rebase --interactive" did not handle its "--strategy" option
+ properly.
--- /dev/null
+GIT v1.5.3.6 Release Notes
+==========================
+
+Fixes since v1.5.3.5
+--------------------
+
+ * git-cvsexportcommit handles root commits better.
+
+ * git-svn dcommit used to clobber when sending a series of
+ patches.
+
+ * git-svn dcommit failed after attempting to rebase when
+ started with a dirty index; now it stops upfront.
+
+ * git-grep sometimes refused to work when your index was
+ unmerged.
+
+ * "git-grep -A1 -B2" acted as if it was told to run "git -A1 -B21".
+
+ * git-hash-object did not honor configuration variables, such as
+ core.compression.
+
+ * git-index-pack choked on a huge pack on 32-bit machines, even when
+ large file offsets are supported.
+
+ * atom feeds from git-web said "10" for the month of November.
+
+ * a memory leak in commit walker was plugged.
+
+ * When git-send-email inserted the original author's From:
+ address in body, it did not mark the message with
+ Content-type: as needed.
+
+ * git-revert and git-cherry-pick incorrectly refused to start
+ when the work tree was dirty.
+
+ * git-clean did not honor core.excludesfile configuration.
+
+ * git-add mishandled ".gitignore" files when applying them to
+ subdirectories.
+
+ * While importing a too branchy history, git-fastimport did not
+ honor delta depth limit properly.
+
+ * Support for zlib implementations that lack ZLIB_VERNUM and definition
+ of deflateBound() has been added.
+
+ * Quite a lot of documentation clarifications.
--- /dev/null
+GIT v1.5.3.7 Release Notes
+==========================
+
+Fixes since v1.5.3.6
+--------------------
+
+ * git-send-email added 8-bit contents to the payload without
+ marking it as 8-bit in a CTE header.
+
+ * "git-bundle create a.bndl HEAD" dereferenced the symref and
+ did not record the ref as 'HEAD'; this prevented a bundle
+ from being used as a normal source of git-clone.
+
+ * The code to reject nonsense command line of the form
+ "git-commit -a paths..." and "git-commit --interactive
+ paths..." were broken.
+
+ * Adding a signature that is not ASCII-only to an original
+ commit that is ASCII-only would make the result non-ASCII.
+ "git-format-patch -s" did not mark such a message correctly
+ with MIME encoding header.
+
+ * git-add sometimes did not mark the resulting index entry
+ stat-clean. This affected only cases when adding the
+ contents with the same length as the previously staged
+ contents, and the previous staging made the index entry
+ "racily clean".
+
+ * git-commit did not honor GIT_INDEX_FILE the user had in the
+ environment.
+
+ * When checking out a revision, git-checkout did not report where the
+ updated HEAD is if you happened to have a file called HEAD in the
+ work tree.
+
+ * "git-rev-list --objects" mishandled a tree that points at a
+ submodule.
+
+ * "git cvsimport" was not ready for packed refs that "git gc" can
+ produce and gave incorrect results.
+
+ * Many scripted Porcelains were confused when you happened to have a
+ file called "HEAD" in your work tree.
+
+Also it contains updates to the user manual and documentation.

+GIT v1.5.3.8 Release Notes
+==========================
+
+Fixes since v1.5.3.7
+--------------------
+
+ * Some documentation used "email.com" as an example domain.
+
+ * git-svn fix to handle funky branch and project names going over
+ http/https correctly.
+
+ * git-svn fix to tone down a needlessly alarming warning message.
+
+ * git-clone did not correctly report errors while fetching over http.
+
+ * git-send-email added redundant Message-Id: header to the outgoing
+ e-mail when the patch text already had one.
+
+ * a read-beyond-end-of-buffer bug in configuration file updater was fixed.
+
+ * git-grep used to show the same hit repeatedly for unmerged paths.
+
+ * After amending the patch title in "git-am -i", the command did not
+ report the patch it applied with the updated title.
+
--- /dev/null
+GIT v1.5.3 Release Notes
+========================
+
+Updates since v1.5.2
+--------------------
+
+* The commit walkers other than http are officially deprecated,
+ but still supported for now.
+
+* The submodule support has Porcelain layer.
+
+ Note that the current submodule support is minimal and this is
+ deliberately so. A design decision we made is that operations
+ at the supermodule level do not recurse into submodules by
+ default. The expectation is that later we would add a
+ mechanism to tell git which submodules the user is interested
+ in, and this information might be used to determine the
+ recursive behaviour of certain commands (e.g. "git checkout"
+ and "git diff"), but currently we haven't agreed on what that
+ mechanism should look like. Therefore, if you use submodules,
+ you would probably need "git submodule update" on the
+ submodules you care about after running a "git checkout" at
+ the supermodule level.
+
+* There are a handful pack-objects changes to help you cope better
+ with repositories with pathologically large blobs in them.
+
+* For people who need to import from Perforce, a front-end for
+ fast-import is in contrib/fast-import/.
+
+* Comes with git-gui 0.8.2.
+
+* Comes with updated gitk.
+
+* New commands and options.
+
+ - "git log --date=<format>" can use more formats: iso8601, rfc2822.
+
+ - The hunk header output from "git diff" family can be customized
+ with the attributes mechanism. See gitattributes(5) for details.
+
+ - "git stash" allows you to quickly save away your work in
+ progress and replay it later on an updated state.
+
+ - "git rebase" learned an "interactive" mode that let you
+ pick and reorder which commits to rebuild.
+
+ - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
+ separate invocation of "git lost-found" command. The blobs stored by
+ lost-found are stored in plain format to allow you to grep in them.
+
+ - $GIT_WORK_TREE environment variable can be used together with
+ $GIT_DIR to work in a subdirectory of a working tree that is
+ not located at "$GIT_DIR/..".
+
+ - Giving "--file=<file>" option to "git config" is the same as
+ running the command with GIT_CONFIG=<file> environment.
+
+ - "git log" learned a new option "--follow", to follow
+ renaming history of a single file.
+
+ - "git filter-branch" lets you rewrite the revision history of
+ specified branches. You can specify a number of filters to
+ modify the commits, files and trees.
+
+ - "git cvsserver" learned new options (--base-path, --export-all,
+ --strict-paths) inspired by "git daemon".
+
+ - "git daemon --base-path-relaxed" can help migrating a repository URL
+ that did not use to use --base-path to use --base-path.
+
+ - "git commit" can use "-t templatefile" option and commit.template
+ configuration variable to prime the commit message given to you in the
+ editor.
+
+ - "git submodule" command helps you manage the projects from
+ the superproject that contain them.
+
+ - In addition to core.compression configuration option,
+ core.loosecompression and pack.compression options can
+ independently tweak zlib compression levels used for loose
+ and packed objects.
+
+ - "git ls-tree -l" shows size of blobs pointed at by the
+ tree entries, similar to "/bin/ls -l".
+
+ - "git rev-list" learned --regexp-ignore-case and
+ --extended-regexp options to tweak its matching logic used
+ for --grep filtering.
+
+ - "git describe --contains" is a handier way to call more
+ obscure command "git name-rev --tags".
+
+ - "git gc --aggressive" tells the command to spend more cycles
+ to optimize the repository harder.
+
+ - "git repack" learned a "window-memory" limit which
+ dynamically reduces the window size to stay within the
+ specified memory usage.
+
+ - "git repack" can be told to split resulting packs to avoid
+ exceeding limit specified with "--max-pack-size".
+
+ - "git fsck" gained --verbose option. This is really really
+ verbose but it might help you identify exact commit that is
+ corrupt in your repository.
+
+ - "git format-patch" learned --numbered-files option. This
+ may be useful for MH users.
+
+ - "git format-patch" learned format.subjectprefix configuration
+ variable, which serves the same purpose as "--subject-prefix"
+ option.
+
+ - "git tag -n -l" shows tag annotations while listing tags.
+
+ - "git cvsimport" can optionally use the separate-remote layout.
+
+ - "git blame" can be told to see through commits that change
+ whitespaces and indentation levels with "-w" option.
+
+ - "git send-email" can be told not to thread the messages when
+ sending out more than one patches.
+
+ - "git send-email" can also be told how to find whom to cc the
+ message to for each message via --cc-cmd.
+
+ - "git config" learned NUL terminated output format via -z to
+ help scripts.
+
+ - "git add" learned "--refresh <paths>..." option to selectively refresh
+ the cached stat information.
+
+ - "git init -q" makes the command quieter.
+
+ - "git -p command" now has a cousin of opposite sex, "git --no-pager
+ command".
+
+* Updated behavior of existing commands.
+
+ - "gitweb" can offer multiple snapshot formats.
+
+ ***NOTE*** Unfortunately, this changes the format of the
+ $feature{snapshot}{default} entry in the per-site
+ configuration file 'gitweb_config.perl'. It used to be a
+ three-element tuple that describe a single format; with the
+ new configuration item format, you only have to say the name
+ of the format ('tgz', 'tbz2' or 'zip'). Please update the
+ your configuration file accordingly.
+
+ - "git clone" uses -l (hardlink files under .git) by default when
+ cloning locally.
+
+ - URL used for "git clone" and friends can specify nonstandard SSH port
+ by using ssh://host:port/path/to/repo syntax.
+
+ - "git bundle create" can now create a bundle without negative refs,
+ i.e. "everything since the beginning up to certain points".
+
+ - "git diff" (but not the plumbing level "git diff-tree") now
+ recursively descends into trees by default.
+
+ - "git diff" does not show differences that come only from
+ stat-dirtiness in the form of "diff --git" header anymore.
+ It runs "update-index --refresh" silently as needed.
+
+ - "git tag -l" used to match tags by globbing its parameter as if it
+ has wildcard '*' on both ends, which made "git tag -l gui" to match
+ tag 'gitgui-0.7.0'; this was very annoying. You now have to add
+ asterisk on the sides you want to wildcard yourself.
+
+ - The editor to use with many interactive commands can be
+ overridden with GIT_EDITOR environment variable, or if it
+ does not exist, with core.editor configuration variable. As
+ before, if you have neither, environment variables VISUAL
+ and EDITOR are consulted in this order, and then finally we
+ fall back on "vi".
+
+ - "git rm --cached" does not complain when removing a newly
+ added file from the index anymore.
+
+ - Options to "git log" to affect how --grep/--author options look for
+ given strings now have shorter abbreviations. -i is for ignore case,
+ and -E is for extended regexp.
+
+ - "git log" learned --log-size to show the number of bytes in
+ the log message part of the output to help qgit.
+
+ - "git log --name-status" does not require you to give "-r" anymore.
+ As a general rule, Porcelain commands should recurse when showing
+ diff.
+
+ - "git format-patch --root A" can be used to format everything
+ since the beginning up to A. This was supported with
+ "git format-patch --root A A" for a long time, but was not
+ properly documented.
+
+ - "git svn dcommit" retains local merge information.
+
+ - "git svnimport" allows an empty string to be specified as the
+ trunk/ directory. This is necessary to suck data from a SVN
+ repository that doe not have trunk/ branches/ and tags/ organization
+ at all.
+
+ - "git config" to set values also honors type flags like --bool
+ and --int.
+
+ - core.quotepath configuration can be used to make textual git
+ output to emit most of the characters in the path literally.
+
+ - "git mergetool" chooses its backend more wisely, taking
+ notice of its environment such as use of X, Gnome/KDE, etc.
+
+ - "gitweb" shows merge commits a lot nicer than before. The
+ default view uses more compact --cc format, while the UI
+ allows to choose normal diff with any parent.
+
+ - snapshot files "gitweb" creates from a repository at
+ $path/$project/.git are more useful. We use $project part
+ in the filename, which we used to discard.
+
+ - "git cvsimport" creates lightweight tags; there is no
+ interesting information we can record in an annotated tag,
+ and the handcrafted ones the old code created was not
+ properly formed anyway.
+
+ - "git push" pretends that you immediately fetched back from
+ the remote by updating corresponding remote tracking
+ branches if you have any.
+
+ - The diffstat given after a merge (or a pull) honors the
+ color.diff configuration.
+
+ - "git commit --amend" is now compatible with various message source
+ options such as -m/-C/-c/-F.
+
+ - "git apply --whitespace=strip" removes blank lines added at
+ the end of the file.
+
+ - "git fetch" over git native protocols with "-v" option shows
+ connection status, and the IP address of the other end, to
+ help diagnosing problems.
+
+ - We used to have core.legacyheaders configuration, when
+ set to false, allowed git to write loose objects in a format
+ that mimics the format used by objects stored in packs. It
+ turns out that this was not so useful. Although we will
+ continue to read objects written in that format, we do not
+ honor that configuration anymore and create loose objects in
+ the legacy/traditional format.
+
+ - "--find-copies-harder" option to diff family can now be
+ spelled as "-C -C" for brevity.
+
+ - "git mailsplit" (hence "git am") can read from Maildir
+ formatted mailboxes.
+
+ - "git cvsserver" does not barf upon seeing "cvs login"
+ request.
+
+ - "pack-objects" honors "delta" attribute set in
+ .gitattributes. It does not attempt to deltify blobs that
+ come from paths with delta attribute set to false.
+
+ - "new-workdir" script (in contrib) can now be used with a
+ bare repository.
+
+ - "git mergetool" learned to use gvimdiff.
+
+ - "gitview" (in contrib) has a better blame interface.
+
+ - "git log" and friends did not handle a commit log message
+ that is larger than 16kB; they do now.
+
+ - "--pretty=oneline" output format for "git log" and friends
+ deals with "malformed" commit log messages that have more
+ than one lines in the first paragraph better. We used to
+ show the first line, cutting the title at mid-sentence; we
+ concatenate them into a single line and treat the result as
+ "oneline".
+
+ - "git p4import" has been demoted to contrib status. For
+ a superior option, checkout the "git p4" front end to
+ "git fast-import" (also in contrib). The man page and p4
+ rpm have been removed as well.
+
+ - "git mailinfo" (hence "am") now tries to see if the message
+ is in utf-8 first, instead of assuming iso-8859-1, if
+ incoming e-mail does not say what encoding it is in.
+
+* Builds
+
+ - old-style function definitions (most notably, a function
+ without parameter defined with "func()", not "func(void)")
+ have been eradicated.
+
+ - "git tag" and "git verify-tag" have been rewritten in C.
+
+* Performance Tweaks
+
+ - "git pack-objects" avoids re-deltification cost by caching
+ small enough delta results it creates while looking for the
+ best delta candidates.
+
+ - "git pack-objects" learned a new heuristic to prefer delta
+ that is shallower in depth over the smallest delta
+ possible. This improves both overall packfile access
+ performance and packfile density.
+
+ - diff-delta code that is used for packing has been improved
+ to work better on big files.
+
+ - when there are more than one pack files in the repository,
+ the runtime used to try finding an object always from the
+ newest packfile; it now tries the same packfile as we found
+ the object requested the last time, which exploits the
+ locality of references.
+
+ - verifying pack contents done by "git fsck --full" got boost
+ by carefully choosing the order to verify objects in them.
+
+ - "git read-tree -m" to read into an already populated index
+ has been optimized vastly. The effect of this can be seen
+ when switching branches that have differences in only a
+ handful paths.
+
+ - "git add paths..." and "git commit paths..." has also been
+ heavily optimized.
+
+Fixes since v1.5.2
+------------------
+
+All of the fixes in v1.5.2 maintenance series are included in
+this release, unless otherwise noted.
+
+* Bugfixes
+
+ - "gitweb" had trouble handling non UTF-8 text with older
+ Encode.pm Perl module.
+
+ - "git svn" misparsed the data from the commits in the repository when
+ the user had "color.diff = true" in the configuration. This has been
+ fixed.
+
+ - There was a case where "git svn dcommit" clobbered changes made on the
+ SVN side while committing multiple changes.
+
+ - "git-write-tree" had a bad interaction with racy-git avoidance and
+ gitattributes mechanisms.
+
+ - "git --bare command" overrode existing GIT_DIR setting and always
+ made it treat the current working directory as GIT_DIR.
+
+ - "git ls-files --error-unmatch" does not complain if you give the
+ same path pattern twice by mistake.
+
+ - "git init" autodetected core.filemode but not core.symlinks, which
+ made a new directory created automatically by "git clone" cumbersome
+ to use on filesystems that require these configurations to be set.
+
+ - "git log" family of commands behaved differently when run as "git
+ log" (no pathspec) and as "git log --" (again, no pathspec). This
+ inconsistency was introduced somewhere in v1.3.0 series but now has
+ been corrected.
+
+ - "git rebase -m" incorrectly displayed commits that were skipped.

+GIT v1.5.4.1 Release Notes
+==========================
+
+Fixes since v1.5.4
+------------------
+
+ * "git-commit -C $tag" used to work but rewrite in C done in
+ 1.5.4 broke it.
+
+ * An entry in the .gitattributes file that names a pattern in a
+ subdirectory of the directory it is in did not match
+ correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
+ match "a/b/foo.c" but it didn't).
+
+ * Customized color specification was parsed incorrectly when
+ numeric color values are used. This was fixed in 1.5.4.1.
+
--- /dev/null
+GIT v1.5.4.2 Release Notes
+==========================
+
+Fixes since v1.5.4
+------------------
+
+ * The configuration parser was not prepared to see string
+ valued variables misspelled as boolean and segfaulted.
+
+ * Temporary files left behind due to interrupted object
+ transfers were not cleaned up with "git prune".
+
+ * "git config --unset" was confused when the unset variables
+ were spelled with continuation lines in the config file.
+
+ * The merge message detection in "git cvsimport" did not catch
+ a message that began with "Merge...".
+
+ * "git status" suggests "git rm --cached" for unstaging the
+ earlier "git add" before the initial commit.
+
+ * "git status" output was incorrect during a partial commit.
+
+ * "git bisect" refused to start when the HEAD was detached.
+
+ * "git bisect" allowed a wildcard character in the commit
+ message expanded while writing its log file.
+
+ * Manual pages were not formatted correctly with docbook xsl
+ 1.72; added a workaround.
+
+ * "git-commit -C $tag" used to work but rewrite in C done in
+ 1.5.4 broke it. This was fixed in 1.5.4.1.
+
+ * An entry in the .gitattributes file that names a pattern in a
+ subdirectory of the directory it is in did not match
+ correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
+ match "a/b/foo.c" but it didn't). This was fixed in 1.5.4.1.
+
+ * Customized color specification was parsed incorrectly when
+ numeric color values are used. This was fixed in 1.5.4.1.
+
+ * http transport misbehaved when linked with curl-gnutls.
--- /dev/null
+GIT v1.5.4.3 Release Notes
+==========================
+
+Fixes since v1.5.4.2
+--------------------
+
+ * RPM spec used to pull in everything with 'git'. This has been
+ changed so that 'git' package contains just the core parts,
+ and we now supply 'git-all' metapackage to slurp in everything.
+ This should match end user's expectation better.
+
+ * When some refs failed to update, git-push reported "failure"
+ which was unclear if some other refs were updated or all of
+ them failed atomically (the answer is the former). Reworded
+ the message to clarify this.
+
+ * "git clone" from a repository whose HEAD was misconfigured
+ did not set up the remote properly. Now it tries to do
+ better.
+
+ * Updated git-push documentation to clarify what "matching"
+ means, in order to reduce user confusion.
+
+ * Updated git-add documentation to clarify "add -u" operates in
+ the current subdirectory you are in, just like other commands.
+
+ * git-gui updates to work on OSX and Windows better.
--- /dev/null
+GIT v1.5.4.4 Release Notes
+==========================
+
+Fixes since v1.5.4.3
+--------------------
+
+ * Building and installing with an overtight umask such as 077 made
+ installed templates unreadable by others, while the rest of the install
+ are done in a way that is friendly to umask 022.
+
+ * "git cvsexportcommit -w $cvsdir" misbehaved when GIT_DIR is set to a
+ relative directory.
+
+ * "git http-push" had an invalid memory access that could lead it to
+ segfault.
+
+ * When "git rebase -i" gave control back to the user for a commit that is
+ marked to be edited, it just said "modify it with commit --amend",
+ without saying what to do to continue after modifying it. Give an
+ explicit instruction to run "rebase --continue" to be more helpful.
+
+ * "git send-email" in 1.5.4.3 issued a bogus empty In-Reply-To: header.
+
+ * "git bisect" showed mysterious "won't bisect on seeked tree" error message.
+ This was leftover from Cogito days to prevent "bisect" starting from a
+ cg-seeked state. We still keep the Cogito safety, but running "git bisect
+ start" when another bisect was in effect will clean up and start over.
+
+ * "git push" with an explicit PATH to receive-pack did not quite work if
+ receive-pack was not on usual PATH. We earlier fixed the same issue
+ with "git fetch" and upload-pack, but somehow forgot to do so in the
+ other direction.
+
+ * git-gui's info dialog was not displayed correctly when the user tries
+ to commit nothing (i.e. without staging anything).
+
+ * "git revert" did not properly fail when attempting to run with a
+ dirty index.
+
+ * "git merge --no-commit --no-ff <other>" incorrectly made commits.
+
+ * "git merge --squash --no-ff <other>", which is a nonsense combination
+ of options, was not rejected.
+
+ * "git ls-remote" and "git remote show" against an empty repository
+ failed, instead of just giving an empty result (regression).
+
+ * "git fast-import" did not handle a renamed path whose name needs to be
+ quoted, due to a bug in unquote_c_style() function.
+
+ * "git cvsexportcommit" was confused when multiple files with the same
+ basename needed to be pushed out in the same commit.
+
+ * "git daemon" did not send early errors to syslog.
+
+ * "git log --merge" did not work well with --left-right option.
+
+ * "git svn" prompted for client cert password every time it accessed the
+ server.
+
+ * The reset command in "git fast-import" data stream was documented to
+ end with an optional LF, but it actually required one.
+
+ * "git svn dcommit/rebase" did not honor --rewrite-root option.
+
+Also included are a handful documentation updates.
--- /dev/null
+GIT v1.5.4.5 Release Notes
+==========================
+
+Fixes since v1.5.4.4
+--------------------
+
+ * "git fetch there" when the URL information came from the Cogito style
+ branches/there file did not update refs/heads/there (regression in
+ 1.5.4).
+
+ * Bogus refspec configuration such as "remote.there.fetch = =" were not
+ detected as errors (regression in 1.5.4).
+
+ * You couldn't specify a custom editor whose path contains a whitespace
+ via GIT_EDITOR (and core.editor).
+
+ * The subdirectory filter to "git filter-branch" mishandled a history
+ where the subdirectory becomes empty and then later becomes non-empty.
+
+ * "git shortlog" gave an empty line if the original commit message was
+ malformed (e.g. a botched import from foreign SCM). Now it finds the
+ first non-empty line and uses it for better information.
+
+ * When the user fails to give a revision parameter to "git svn", an error
+ from the Perl interpreter was issued because the script lacked proper
+ error checking.
+
+ * After "git rebase" stopped due to conflicts, if the user played with
+ "git reset" and friends, "git rebase --abort" failed to go back to the
+ correct commit.
+
+ * Additional work trees prepared with git-new-workdir (in contrib/) did
+ not share git-svn metadata directory .git/svn with the original.
+
+ * "git-merge-recursive" did not mark addition of the same path with
+ different filemodes correctly as a conflict.
+
+ * "gitweb" gave malformed URL when pathinfo stype paths are in use.
+
+ * "-n" stands for "--no-tags" again for "git fetch".
+
+ * "git format-patch" did not detect the need to add 8-bit MIME header
+ when the user used format.header configuration.
+
+ * "rev~" revision specifier used to mean "rev", which was inconsistent
+ with how "rev^" worked. Now "rev~" is the same as "rev~1" (hence it
+ also is the same as "rev^1"), and "rev~0" is the same as "rev^0"
+ (i.e. it has to be a commit).
+
+ * "git quiltimport" did not grok empty lines, lines in "file -pNNN"
+ format to specify the prefix levels and lines with trailing comments.
+
+ * "git rebase -m" triggered pre-commit verification, which made
+ "rebase --continue" impossible.
+
+As usual, it also comes with many documentation fixes and clarifications.
--- /dev/null
+GIT v1.5.4.6 Release Notes
+==========================
+
+I personally do not think there is any reason anybody should want to
+run v1.5.4.X series these days, because 'master' version is always
+more stable than any tagged released version of git.
+
+This is primarily to futureproof "git-shell" to accept requests
+without a dash between "git" and subcommand name (e.g. "git
+upload-pack") which the newer client will start to make sometime in
+the future.
+
+Fixes since v1.5.4.5
+--------------------
+
+ * Command line option "-n" to "git-repack" was not correctly parsed.
+
+ * Error messages from "git-apply" when the patchfile cannot be opened
+ have been improved.
+
+ * Error messages from "git-bisect" when given nonsense revisions have
+ been improved.
+
+ * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
+ stop parsing at the closing "}".
+
+ * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
+ but it should print nothing.
+
+ * "git apply" did not enforce "match at the beginning" correctly.
+
+ * a path specification "a/b" in .gitattributes file should not match
+ "sub/a/b", but it did.
+
+ * "git log --date-order --topo-order" did not override the earlier
+ date-order with topo-order as expected.
+
+ * "git fast-export" did not export octopus merges correctly.
+
+ * "git archive --prefix=$path/" mishandled gitattributes.
+
+As usual, it also comes with many documentation fixes and clarifications.
+
--- /dev/null
+GIT v1.5.4.7 Release Notes
+==========================
+
+Fixes since 1.5.4.7
+-------------------
+
+ * Removed support for an obsolete gitweb request URI, whose
+ implementation ran "git diff" Porcelain, instead of using plumbing,
+ which would have run an external diff command specified in the
+ repository configuration as the gitweb user.
--- /dev/null
+GIT v1.5.4 Release Notes
+========================
+
+Removal
+-------
+
+ * "git svnimport" was removed in favor of "git svn". It is still there
+ in the source tree (contrib/examples) but unsupported.
+
+ * As git-commit and git-status have been rewritten, "git runstatus"
+ helper script lost all its users and has been removed.
+
+
+Temporarily disabled
+--------------------
+
+ * "git http-push" is known not to work well with cURL library older
+ than 7.16, and we had reports of repository corruption. It is
+ disabled on such platforms for now. Unfortunately, 1.5.3.8 shares
+ the same issue. In other words, this does not mean you will be
+ fine if you stick to an older git release. For now, please do not
+ use http-push from older git with cURL older than 7.16 if you
+ value your data. A proper fix will hopefully materialize in
+ later versions.
+
+
+Deprecation notices
+-------------------
+
+ * From v1.6.0, git will by default install dashed form of commands
+ (e.g. "git-commit") outside of users' normal $PATH, and will install
+ only selected commands ("git" itself, and "gitk") in $PATH. This
+ implies:
+
+ - Using dashed forms of git commands (e.g. "git-commit") from the
+ command line has been informally deprecated since early 2006, but
+ now it officially is, and will be removed in the future. Use
+ dash-less forms (e.g. "git commit") instead.
+
+ - Using dashed forms from your scripts, without first prepending the
+ return value from "git --exec-path" to the scripts' PATH, has been
+ informally deprecated since early 2006, but now it officially is.
+
+ - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
+ PATH" early in your script is not deprecated with this change.
+
+ Users are strongly encouraged to adjust their habits and scripts now
+ to prepare for this change.
+
+ * The post-receive hook was introduced in March 2007 to supersede
+ the post-update hook, primarily to overcome the command line length
+ limitation of the latter. Use of post-update hook will be deprecated
+ in future versions of git, starting from v1.6.0.
+
+ * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
+ option, and will be removed in the future.
+
+ * "git peek-remote" is deprecated, as "git ls-remote" was written in C
+ and works for all transports; "git peek-remote" will be removed in
+ the future.
+
+ * "git repo-config" which was an old name for "git config" command
+ has been supported without being advertised for a long time. The
+ next feature release will remove it.
+
+ * From v1.6.0, the repack.usedeltabaseoffset config option will default
+ to true, which will give denser packfiles (i.e. more efficient storage).
+ The downside is that git older than version 1.4.4 will not be able
+ to directly use a repository packed using this setting.
+
+ * From v1.6.0, the pack.indexversion config option will default to 2,
+ which is slightly more efficient, and makes repacking more immune to
+ data corruptions. Git older than version 1.5.2 may revert to version 1
+ of the pack index with a manual "git index-pack" to be able to directly
+ access corresponding pack files.
+
+
+Updates since v1.5.3
+--------------------
+
+ * Comes with much improved gitk, with i18n.
+
+ * Comes with git-gui 0.9.2 with i18n.
+
+ * gitk is now merged as a subdirectory of git.git project, in
+ preparation for its i18n.
+
+ * progress displays from many commands are a lot nicer to the eye.
+ Transfer commands show throughput data.
+
+ * many commands that pay attention to per-directory .gitignore now do
+ so lazily, which makes the usual case go much faster.
+
+ * Output processing for '--pretty=format:<user format>' has been
+ optimized.
+
+ * Rename detection of diff family while detecting exact matches has
+ been greatly optimized.
+
+ * Rename detection of diff family tries to make more natural looking
+ pairing. Earlier, if multiple identical rename sources were
+ found in the preimage, the source used was picked pretty much at random.
+
+ * Value "true" for color.diff and color.status configuration used to
+ mean "always" (even when the output is not going to a terminal).
+ This has been corrected to mean the same thing as "auto".
+
+ * "git diff" Porcelain now respects diff.external configuration, which
+ is another way to specify GIT_EXTERNAL_DIFF.
+
+ * "git diff" can be told to use different prefixes other than
+ "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
+
+ * "git diff" sometimes did not quote paths with funny
+ characters properly.
+
+ * "git log" (and any revision traversal commands) misbehaved
+ when --diff-filter is given but was not asked to actually
+ produce diff.
+
+ * HTTP proxy can be specified per remote repository using
+ remote.*.httpproxy configuration, or global http.proxy configuration
+ variable.
+
+ * Various Perforce importer updates.
+
+ * Example update and post-receive hooks have been improved.
+
+ * Any command that wants to take a commit object name can now use
+ ":/string" syntax to name a commit.
+
+ * "git reset" is now built-in and its output can be squelched with -q.
+
+ * "git reset --hard" does not make any sense in a bare
+ repository, but did not error out; fixed.
+
+ * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
+
+ * "git rebase" learned --whitespace option.
+
+ * In "git rebase", when you decide not to replay a particular change
+ after the command stopped with a conflict, you can say "git rebase
+ --skip" without first running "git reset --hard", as the command now
+ runs it for you.
+
+ * "git rebase --interactive" mode can now work on detached HEAD.
+
+ * Other minor to serious bugs in "git rebase -i" have been fixed.
+
+ * "git rebase" now detaches head during its operation, so after a
+ successful "git rebase" operation, the reflog entry branch@{1} for
+ the current branch points at the commit before the rebase was
+ started.
+
+ * "git rebase -i" also triggers rerere to help your repeated merges.
+
+ * "git merge" can call the "post-merge" hook.
+
+ * "git pack-objects" can optionally run deltification with multiple
+ threads.
+
+ * "git archive" can optionally substitute keywords in files marked with
+ export-subst attribute.
+
+ * "git cherry-pick" made a misguided attempt to repeat the original
+ command line in the generated log message, when told to cherry-pick a
+ commit by naming a tag that points at it. It does not anymore.
+
+ * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the
+ various date fields in different formats.
+
+ * "git gc --auto" is a low-impact way to automatically run a variant of
+ "git repack" that does not lose unreferenced objects (read: safer
+ than the usual one) after the user accumulates too many loose
+ objects.
+
+ * "git clean" has been rewritten in C.
+
+ * You need to explicitly set clean.requireForce to "false" to allow
+ "git clean" without -f to do any damage (lack of the configuration
+ variable used to mean "do not require -f option to lose untracked
+ files", but we now use the safer default).
+
+ * The kinds of whitespace errors "git diff" and "git apply" notice (and
+ fix) can be controlled via 'core.whitespace' configuration variable
+ and 'whitespace' attribute in .gitattributes file.
+
+ * "git push" learned --dry-run option to show what would happen if a
+ push is run.
+
+ * "git push" does not update a tracking ref on the local side when the
+ remote refused to update the corresponding ref.
+
+ * "git push" learned --mirror option. This is to push the local refs
+ one-to-one to the remote, and deletes refs from the remote that do
+ not exist anymore in the repository on the pushing side.
+
+ * "git push" can remove a corrupt ref at the remote site with the usual
+ ":ref" refspec.
+
+ * "git remote" knows --mirror mode. This is to set up configuration to
+ push into a remote repository to store local branch heads to the same
+ branch on the remote side, and remove branch heads locally removed
+ from local repository at the same time. Suitable for pushing into a
+ back-up repository.
+
+ * "git remote" learned "rm" subcommand.
+
+ * "git cvsserver" can be run via "git shell". Also, "cvs" is
+ recognized as a synonym for "git cvsserver", so that CVS users
+ can be switched to git just by changing their login shell.
+
+ * "git cvsserver" acts more like receive-pack by running post-receive
+ and post-update hooks.
+
+ * "git am" and "git rebase" are far less verbose.
+
+ * "git pull" learned to pass --[no-]ff option to underlying "git
+ merge".
+
+ * "git pull --rebase" is a different way to integrate what you fetched
+ into your current branch.
+
+ * "git fast-export" produces data-stream that can be fed to fast-import
+ to reproduce the history recorded in a git repository.
+
+ * "git add -i" takes pathspecs to limit the set of files to work on.
+
+ * "git add -p" is a short-hand to go directly to the selective patch
+ subcommand in the interactive command loop and to exit when done.
+
+ * "git add -i" UI has been colorized. The interactive prompt
+ and menu can be colored by setting color.interactive
+ configuration. The diff output (including the hunk picker)
+ are colored with color.diff configuration.
+
+ * "git commit --allow-empty" allows you to create a single-parent
+ commit that records the same tree as its parent, overriding the usual
+ safety valve.
+
+ * "git commit --amend" can amend a merge that does not change the tree
+ from its first parent.
+
+ * "git commit" used to unconditionally strip comment lines that
+ began with '#' and removed excess blank lines. This behavior has
+ been made configurable.
+
+ * "git commit" has been rewritten in C.
+
+ * "git stash random-text" does not create a new stash anymore. It was
+ a UI mistake. Use "git stash save random-text", or "git stash"
+ (without extra args) for that.
+
+ * "git stash clear extra-text" does not clear the whole stash
+ anymore. It is tempting to expect "git stash clear stash@{2}"
+ to drop only a single named stash entry, and it is rude to
+ discard everything when that is asked (but not provided).
+
+ * "git prune --expire <time>" can exempt young loose objects from
+ getting pruned.
+
+ * "git branch --contains <commit>" can list branches that are
+ descendants of a given commit.
+
+ * "git log" learned --early-output option to help interactive GUI
+ implementations.
+
+ * "git bisect" learned "skip" action to mark untestable commits.
+
+ * "git bisect visualize" learned a shorter synonym "git bisect view".
+
+ * "git bisect visualize" runs "git log" in a non-windowed
+ environments. It also can be told what command to run (e.g. "git
+ bisect visualize tig").
+
+ * "git format-patch" learned "format.numbered" configuration variable
+ to automatically turn --numbered option on when more than one commits
+ are formatted.
+
+ * "git ls-files" learned "--exclude-standard" to use the canned set of
+ exclude files.
+
+ * "git tag -a -f existing" begins the editor session using the existing
+ annotation message.
+
+ * "git tag -m one -m bar" (multiple -m options) behaves similarly to
+ "git commit"; the parameters to -m options are formatted as separate
+ paragraphs.
+
+ * The format "git show" outputs an annotated tag has been updated to
+ include "Tagger: " and "Date: " lines from the tag itself. Strictly
+ speaking this is a backward incompatible change, but this is a
+ reasonable usability fix and people's scripts shouldn't have been
+ relying on the exact output from "git show" Porcelain anyway.
+
+ * "git cvsimport" did not notice errors from underlying "cvsps"
+ and produced a corrupt import silently.
+
+ * "git cvsexportcommit" learned -w option to specify and switch to the
+ CVS working directory.
+
+ * "git checkout" from a subdirectory learned to use "../path" to allow
+ checking out a path outside the current directory without cd'ing up.
+
+ * "git checkout" from and to detached HEAD leaves a bit more
+ information in the reflog.
+
+ * "git send-email --dry-run" shows full headers for easier diagnosis.
+
+ * "git merge-ours" is now built-in.
+
+ * "git svn" learned "info" and "show-externals" subcommands.
+
+ * "git svn" run from a subdirectory failed to read settings from the
+ .git/config.
+
+ * "git svn" learned --use-log-author option, which picks up more
+ descriptive name from From: and Signed-off-by: lines in the commit
+ message.
+
+ * "git svn" wasted way too much disk to record revision mappings
+ between svn and git; a new representation that is much more compact
+ for this information has been introduced to correct this.
+
+ * "git svn" left temporary index files it used without cleaning them
+ up; this was corrected.
+
+ * "git status" from a subdirectory now shows relative paths, which
+ makes copy-and-pasting for git-checkout/git-add/git-rm easier. The
+ traditional behavior to show the full path relative to the top of
+ the work tree can be had by setting status.relativepaths
+ configuration variable to false.
+
+ * "git blame" kept text for each annotated revision in core needlessly;
+ this has been corrected.
+
+ * "git shortlog" learned to default to HEAD when the standard input is
+ a terminal and the user did not give any revision parameter.
+
+ * "git shortlog" learned "-e" option to show e-mail addresses as well as
+ authors' names.
+
+ * "git help" learned "-w" option to show documentation in browsers.
+
+ * In addition there are quite a few internal clean-ups. Notably:
+
+ - many fork/exec have been replaced with run-command API,
+ brought from the msysgit effort.
+
+ - introduction and more use of the option parser API.
+
+ - enhancement and more use of the strbuf API.
+
+ * Makefile tweaks to support HP-UX is in.
+
+Fixes since v1.5.3
+------------------
+
+All of the fixes in v1.5.3 maintenance series are included in
+this release, unless otherwise noted.
+
+These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
+series.
+
+ * The way "git diff --check" behaves is much more consistent with the way
+ "git apply --whitespace=warn" works.
+
+ * "git svn" talking with the SVN over HTTP will correctly quote branch
+ and project names.
+
+ * "git config" did not work correctly on platforms that define
+ REG_NOMATCH to an even number.
+
+ * Recent versions of AsciiDoc 8 has a change to break our
+ documentation; a workaround has been implemented.
+
+ * "git diff --color-words" colored context lines in a wrong color.

+GIT v1.5.5.1 Release Notes
+==========================
+
+Fixes since v1.5.5
+------------------
+
+ * "git archive --prefix=$path/" mishandled gitattributes.
+
+ * "git fetch -v" that fetches into FETCH_HEAD did not report the summary
+ the same way as done for updating the tracking refs.
+
+ * "git svn" misbehaved when the configuration file customized the "git
+ log" output format using format.pretty.
+
+ * "git submodule status" leaked an unnecessary error message.
+
+ * "git log --date-order --topo-order" did not override the earlier
+ date-order with topo-order as expected.
+
+ * "git bisect good $this" did not check the validity of the revision
+ given properly.
+
+ * "url.<there>.insteadOf" did not work correctly.
+
+ * "git clean" ran inside subdirectory behaved as if the directory was
+ explicitly specified for removal by the end user from the top level.
+
+ * "git bisect" from a detached head leaked an unnecessary error message.
+
+ * "git bisect good $a $b" when $a is Ok but $b is bogus should have
+ atomically failed before marking $a as good.
+
+ * "git fmt-merge-msg" did not clean up leading empty lines from commit
+ log messages like "git log" family does.
+
+ * "git am" recorded a commit with empty Subject: line without
+ complaining.
+
+ * when given a commit log message whose first paragraph consists of
+ multiple lines, "git rebase" squashed it into a single line.
+
+ * "git remote add $bogus_name $url" did not complain properly.
+
+Also comes with various documentation updates.
--- /dev/null
+GIT v1.5.5.2 Release Notes
+==========================
+
+Fixes since v1.5.5.1
+--------------------
+
+ * "git repack -n" was mistakenly made no-op earlier.
+
+ * "git imap-send" wanted to always have imap.host even when use of
+ imap.tunnel made it unnecessary.
+
+ * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
+ stop parsing at the closing "}".
+
+ * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
+ but it should print nothing.
+
+ * "git commit" did not detect when it failed to write tree objects.
+
+ * "git fetch" sometimes transferred too many objects unnecessarily.
+
+ * a path specification "a/b" in .gitattributes file should not match
+ "sub/a/b".
+
+ * various gitweb fixes.
+
+Also comes with various documentation updates.
--- /dev/null
+GIT v1.5.5.3 Release Notes
+==========================
+
+Fixes since v1.5.5.2
+--------------------
+
+ * "git send-email --compose" did not notice that non-ascii contents
+ needed some MIME magic.
+
+ * "git fast-export" did not export octopus merges correctly.
+
+Also comes with various documentation updates.
--- /dev/null
+GIT v1.5.5.4 Release Notes
+==========================
+
+Fixes since v1.5.5.4
+--------------------
+
+ * "git name-rev --all" used to segfault.
--- /dev/null
+GIT v1.5.5.5 Release Notes
+==========================
+
+I personally do not think there is any reason anybody should want to
+run v1.5.5.X series these days, because 'master' version is always
+more stable than any tagged released version of git.
+
+This is primarily to futureproof "git-shell" to accept requests
+without a dash between "git" and subcommand name (e.g. "git
+upload-pack") which the newer client will start to make sometime in
+the future.
--- /dev/null
+GIT v1.5.5.6 Release Notes
+==========================
+
+Fixes since 1.5.5.5
+-------------------
+
+ * Removed support for an obsolete gitweb request URI, whose
+ implementation ran "git diff" Porcelain, instead of using plumbing,
+ which would have run an external diff command specified in the
+ repository configuration as the gitweb user.
--- /dev/null
+GIT v1.5.5 Release Notes
+========================
+
+Updates since v1.5.4
+--------------------
+
+(subsystems)
+
+ * Comes with git-gui 0.10.1
+
+(portability)
+
+ * We shouldn't ask for BSD group ownership semantics by setting g+s bit
+ on directories on older BSD systems that refuses chmod() by non root
+ users. BSD semantics is the default there anyway.
+
+ * Bunch of portability improvement patches coming from an effort to port
+ to Solaris has been applied.
+
+(performance)
+
+ * On platforms with suboptimal qsort(3) implementation, there
+ is an option to use more reasonable substitute we ship with
+ our software.
+
+ * New configuration variable "pack.packsizelimit" can be used
+ in place of command line option --max-pack-size.
+
+ * "git fetch" over the native git protocol used to make a
+ connection to find out the set of current remote refs and
+ another to actually download the pack data. We now use only
+ one connection for these tasks.
+
+ * "git commit" does not run lstat(2) more than necessary
+ anymore.
+
+(usability, bells and whistles)
+
+ * Bash completion script (in contrib) are aware of more commands and
+ options.
+
+ * You can be warned when core.autocrlf conversion is applied in
+ such a way that results in an irreversible conversion.
+
+ * A catch-all "color.ui" configuration variable can be used to
+ enable coloring of all color-capable commands, instead of
+ individual ones such as "color.status" and "color.branch".
+
+ * The commands refused to take absolute pathnames where they
+ require pathnames relative to the work tree or the current
+ subdirectory. They now can take absolute pathnames in such a
+ case as long as the pathnames do not refer outside of the
+ work tree. E.g. "git add $(pwd)/foo" now works.
+
+ * Error messages used to be sent to stderr, only to get hidden,
+ when $PAGER was in use. They now are sent to stdout along
+ with the command output to be shown in the $PAGER.
+
+ * A pattern "foo/" in .gitignore file now matches a directory
+ "foo". Pattern "foo" also matches as before.
+
+ * bash completion's prompt helper function can talk about
+ operation in-progress (e.g. merge, rebase, etc.).
+
+ * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
+ used to tell "git-fetch" and "git-push" to use different URL than what
+ is given from the command line.
+
+ * "git add -i" behaves better even before you make an initial commit.
+
+ * "git am" refused to run from a subdirectory without a good reason.
+
+ * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
+ a line before the fix can appear as a context or preimage line in a
+ later patch, causing the patch not to apply. The command now knows to
+ see through whitespace fixes done to context lines to successfully
+ apply such a patch series.
+
+ * "git branch" (and "git checkout -b") to branch from a local branch can
+ optionally set "branch.<name>.merge" to mark the new branch to build on
+ the other local branch, when "branch.autosetupmerge" is set to
+ "always", or when passing the command line option "--track" (this option
+ was ignored when branching from local branches). By default, this does
+ not happen when branching from a local branch.
+
+ * "git checkout" to switch to a branch that has "branch.<name>.merge" set
+ (i.e. marked to build on another branch) reports how much the branch
+ and the other branch diverged.
+
+ * When "git checkout" has to update a lot of paths, it used to be silent
+ for 4 seconds before it showed any progress report. It is now a bit
+ more impatient and starts showing progress report early.
+
+ * "git commit" learned a new hook "prepare-commit-msg" that can
+ inspect what is going to be committed and prepare the commit
+ log message template to be edited.
+
+ * "git cvsimport" can now take more than one -M options.
+
+ * "git describe" learned to limit the tags to be used for
+ naming with --match option.
+
+ * "git describe --contains" now barfs when the named commit
+ cannot be described.
+
+ * "git describe --exact-match" describes only commits that are tagged.
+
+ * "git describe --long" describes a tagged commit as $tag-0-$sha1,
+ instead of just showing the exact tagname.
+
+ * "git describe" warns when using a tag whose name and path contradict
+ with each other.
+
+ * "git diff" learned "--relative" option to limit and output paths
+ relative to the current directory when working in a subdirectory.
+
+ * "git diff" learned "--dirstat" option to show birds-eye-summary of
+ changes more concisely than "--diffstat".
+
+ * "git format-patch" learned --cover-letter option to generate a cover
+ letter template.
+
+ * "git gc" learned --quiet option.
+
+ * "git gc" now automatically prunes unreachable objects that are two
+ weeks old or older.
+
+ * "git gc --auto" can be disabled more easily by just setting gc.auto
+ to zero. It also tolerates more packfiles by default.
+
+ * "git grep" now knows "--name-only" is a synonym for the "-l" option.
+
+ * "git help <alias>" now reports "'git <alias>' is alias to <what>",
+ instead of saying "No manual entry for git-<alias>".
+
+ * "git help" can use different backends to show manual pages and this can
+ be configured using "man.viewer" configuration.
+
+ * "gitk" does not restore window position from $HOME/.gitk anymore (it
+ still restores the size).
+
+ * "git log --grep=<what>" learned "--fixed-strings" option to look for
+ <what> without treating it as a regular expression.
+
+ * "git gui" learned an auto-spell checking.
+
+ * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
+ expected; they push the current branch (and only the current branch).
+ In addition, HEAD can be written as the value of "remote.<there>.push"
+ configuration variable.
+
+ * When the configuration variable "pack.threads" is set to 0, "git
+ repack" auto detects the number of CPUs and uses that many threads.
+
+ * "git send-email" learned to prompt for passwords
+ interactively.
+
+ * "git send-email" learned an easier way to suppress CC
+ recipients.
+
+ * "git stash" learned "pop" command, that applies the latest stash and
+ removes it from the stash, and "drop" command to discard the named
+ stash entry.
+
+ * "git submodule" learned a new subcommand "summary" to show the
+ symmetric difference between the HEAD version and the work tree version
+ of the submodule commits.
+
+ * Various "git cvsimport", "git cvsexportcommit", "git cvsserver",
+ "git svn" and "git p4" improvements.
+
+(internal)
+
+ * Duplicated code between git-help and git-instaweb that
+ launches user's preferred browser has been refactored.
+
+ * It is now easier to write test scripts that records known
+ breakages.
+
+ * "git checkout" is rewritten in C.
+
+ * "git remote" is rewritten in C.
+
+ * Two conflict hunks that are separated by a very short span of common
+ lines are now coalesced into one larger hunk, to make the result easier
+ to read.
+
+ * Run-command API's use of file descriptors is documented clearer and
+ is more consistent now.
+
+ * diff output can be sent to FILE * that is different from stdout. This
+ will help reimplementing more things in C.
+
+Fixes since v1.5.4
+------------------
+
+All of the fixes in v1.5.4 maintenance series are included in
+this release, unless otherwise noted.
+
+ * "git-http-push" did not allow deletion of remote ref with the usual
+ "push <remote> :<branch>" syntax.
+
+ * "git-rebase --abort" did not go back to the right location if
+ "git-reset" was run during the "git-rebase" session.
+
+ * "git imap-send" without setting imap.host did not error out but
+ segfaulted.
--- /dev/null
+GIT v1.5.6.1 Release Notes
+==========================
+
+Fixes since v1.5.6
+------------------
+
+* Last minute change broke loose object creation on AIX.
+
+* (performance fix) We used to make $GIT_DIR absolute path early in the
+ programs but keeping it relative to the current directory internally
+ gives 1-3 per-cent performance boost.
+
+* bash completion knows the new --graph option to git-log family.
+
+
+* git-diff -c/--cc showed unnecessary "deletion" lines at the context
+ boundary.
+
+* git-for-each-ref ignored %(object) and %(type) requests for tag
+ objects.
+
+* git-merge usage had a typo.
+
+* Rebuilding of git-svn metainfo database did not take rewriteRoot
+ option into account.
+
+* Running "git-rebase --continue/--skip/--abort" before starting a
+ rebase gave nonsense error messages.
--- /dev/null
+GIT v1.5.6.2 Release Notes
+==========================
+
+Futureproof
+-----------
+
+ * "git-shell" accepts requests without a dash between "git" and
+ subcommand name (e.g. "git upload-pack") which the newer client will
+ start to make sometime in the future.
+
+Fixes since v1.5.6.1
+--------------------
+
+* "git clone" from a remote that is named with url.insteadOf setting in
+ $HOME/.gitconfig did not work well.
+
+* "git describe --long --tags" segfaulted when the described revision was
+ tagged with a lightweight tag.
+
+* "git diff --check" did not report the result via its exit status
+ reliably.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+ it has branch 'foo/bar', it refuses to lose the existing remote tracking
+ branch and its reflog. The error message has been improved to suggest
+ pruning the remote if the user wants to proceed and get the latest set
+ of branches from the remote, including such 'foo/bar'.
+
+* "git reset file" should mean the same thing as "git reset HEAD file",
+ but we required disambiguating -- even when "file" is not ambiguous.
+
+* "git show" segfaulted when an annotated tag that points at another
+ annotated tag was given to it.
+
+* Optimization for a large import via "git-svn" introduced in v1.5.6 had a
+ serious memory and temporary file leak, which made it unusable for
+ moderately large import.
+
+* "git-svn" mangled remote nickname used in the configuration file
+ unnecessarily.
--- /dev/null
+GIT v1.5.6.3 Release Notes
+==========================
+
+Fixes since v1.5.6.2
+--------------------
+
+* Setting core.sharedrepository to traditional "true" value was supposed to make
+ the repository group writable but should not affect permission for others.
+ However, since 1.5.6, it was broken to drop permission for others when umask is
+ 022, making the repository unreadable by others.
+
+* Setting GIT_TRACE will report spawning of external process via run_command().
+
+* Using an object with very deep delta chain pinned memory needed for extracting
+ intermediate base objects unnecessarily long, leading to excess memory usage.
+
+* Bash completion script did not notice '--' marker on the command
+ line and tried the relatively slow "ref completion" even when
+ completing arguments after one.
+
+* Registering a non-empty blob racily and then truncating the working
+ tree file for it confused "racy-git avoidance" logic into thinking
+ that the path is now unchanged.
+
+* The section that describes attributes related to git-archive were placed
+ in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+ information is not set up properly yet.
+
+* "git clone" had a leftover debugging fprintf().
+
+* "git clone -q" was not quiet enough as it used to and gave object count
+ and progress reports.
+
+* "git clone" marked downloaded packfile with .keep; this could be a
+ good thing if the remote side is well packed but otherwise not,
+ especially for a project that is not really big.
+
+* "git daemon" used to call syslog() from a signal handler, which
+ could raise signals of its own but generally is not reentrant. This
+ was fixed by restructuring the code to report syslog() after the handler
+ returns.
+
+* When "git push" tries to remove a remote ref, and corresponding
+ tracking ref is missing, we used to report error (i.e. failure to
+ remove something that does not exist).
+
+* "git mailinfo" (hence "git am") did not handle commit log messages in a
+ MIME multipart mail correctly.
+
+Contains other various documentation fixes.
--- /dev/null
+GIT v1.5.6.4 Release Notes
+==========================
+
+Fixes since v1.5.6.3
+--------------------
+
+* Various commands could overflow its internal buffer on a platform
+ with small PATH_MAX value in a repository that has contents with
+ long pathnames.
+
+* There wasn't a way to make --pretty=format:%<> specifiers to honor
+ .mailmap name rewriting for authors and committers. Now you can with
+ %aN and %cN.
+
+* Bash completion wasted too many cycles; this has been optimized to be
+ usable again.
+
+* Bash completion lost ref part when completing something like "git show
+ pu:Makefile".
+
+* "git-cvsserver" did not clean up its temporary working area after annotate
+ request.
+
+* "git-daemon" called syslog() from its signal handler, which was a
+ no-no.
+
+* "git-fetch" into an empty repository used to remind that the fetch will
+ be huge by saying "no common commits", but this was an unnecessary
+ noise; it is already known by the user anyway.
+
+* "git-http-fetch" would have segfaulted when pack idx file retrieved
+ from the other side was corrupt.
+
+* "git-index-pack" used too much memory when dealing with a deep delta chain.
+
+* "git-mailinfo" (hence "git-am") did not correctly handle in-body [PATCH]
+ line to override the commit title taken from the mail Subject header.
+
+* "git-rebase -i -p" lost parents that are not involved in the history
+ being rewritten.
+
+* "git-rm" lost track of where the index file was when GIT_DIR was
+ specified as a relative path.
+
+* "git-rev-list --quiet" was not quiet as advertised.
+
+Contains other various documentation fixes.

+GIT v1.5.6.5 Release Notes
+==========================
+
+Fixes since v1.5.6.4
+--------------------
+
+* "git cvsimport" used to spit out "UNKNOWN LINE..." diagnostics to stdout.
+
+* "git commit -F filename" and "git tag -F filename" run from subdirectories
+ did not read the right file.
+
+* "git init --template=" with blank "template" parameter linked files
+ under root directories to .git, which was a total nonsense. Instead, it
+ means "I do not want to use anything from the template directory".
+
+* "git diff-tree" and other diff plumbing ignored diff.renamelimit configuration
+ variable when the user explicitly asked for rename detection.
+
+* "git name-rev --name-only" did not work when "--stdin" option was in effect.
+
+* "git show-branch" mishandled its 8th branch.
+
+* Addition of "git update-index --ignore-submodules" that happened during
+ 1.5.6 cycle broke "git update-index --ignore-missing".
+
+* "git send-email" did not parse charset from an existing Content-type:
+ header properly.
+
+Contains other various documentation fixes.
--- /dev/null
+GIT v1.5.6.6 Release Notes
+==========================
+
+Fixes since 1.5.6.5
+-------------------
+
+ * Removed support for an obsolete gitweb request URI, whose
+ implementation ran "git diff" Porcelain, instead of using plumbing,
+ which would have run an external diff command specified in the
+ repository configuration as the gitweb user.
--- /dev/null
+GIT v1.5.6 Release Notes
+========================
+
+Updates since v1.5.5
+--------------------
+
+(subsystems)
+
+* Comes with updated gitk and git-gui.
+
+(portability)
+
+* git will build on AIX better than before now.
+
+* core.ignorecase configuration variable can be used to work better on
+ filesystems that are not case sensitive.
+
+* "git init" now autodetects the case sensitivity of the filesystem and
+ sets core.ignorecase accordingly.
+
+* cpio is no longer used; neither "curl" binary (libcurl is still used).
+
+(documentation)
+
+* Many freestanding documentation pages have been converted and made
+ available to "git help" (aka "man git<something>") as section 7 of
+ the manual pages. This means bookmarks to some HTML documentation
+ files may need to be updated (eg "tutorial.html" became
+ "gittutorial.html").
+
+(performance)
+
+* "git clone" was rewritten in C. This will hopefully help cloning a
+ repository with insane number of refs.
+
+* "git rebase --onto $there $from $branch" used to switch to the tip of
+ $branch only to immediately reset back to $from, smudging work tree
+ files unnecessarily. This has been optimized.
+
+* Object creation codepath in "git-svn" has been optimized by enhancing
+ plumbing commands git-cat-file and git-hash-object.
+
+(usability, bells and whistles)
+
+* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
+ apply (or not apply) mode changes independently from contents changes.
+
+* "git bisect help" gives longer and more helpful usage information.
+
+* "git bisect" does not use a special branch "bisect" anymore; instead, it
+ does its work on a detached HEAD.
+
+* "git branch" (and "git checkout -b") can be told to set up
+ branch.<name>.rebase automatically, so that later you can say "git pull"
+ and magically cause "git pull --rebase" to happen.
+
+* "git branch --merged" and "git branch --no-merged" can be used to list
+ branches that have already been merged (or not yet merged) to the
+ current branch.
+
+* "git cherry-pick" and "git revert" can add a sign-off.
+
+* "git commit" mentions the author identity when you are committing
+ somebody else's changes.
+
+* "git diff/log --dirstat" output is consistent between binary and textual
+ changes.
+
+* "git filter-branch" rewrites signed tags by demoting them to annotated.
+
+* "git format-patch --no-binary" can produce a patch that lack binary
+ changes (i.e. cannot be used to propagate the whole changes) meant only
+ for reviewing.
+
+* "git init --bare" is a synonym for "git --bare init" now.
+
+* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
+
+* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
+ instead of giving a LF between each pair of entries which is how
+ "git log --pretty=format:<custom format>" works.
+
+* "git log" and friends learned the "--graph" option to show the ancestry
+ graph at the left margin of the output.
+
+* "git log" and friends can be told to use date format that is different
+ from the default via 'log.date' configuration variable.
+
+* "git send-email" now can send out messages outside a git repository.
+
+* "git send-email --compose" was made aware of rfc2047 quoting.
+
+* "git status" can optionally include output from "git submodule
+ summary".
+
+* "git svn" learned --add-author-from option to propagate the authorship
+ by munging the commit log message.
+
+* new object creation and looking up in "git svn" has been optimized.
+
+* "gitweb" can read from a system-wide configuration file.
+
+(internal)
+
+* "git unpack-objects" and "git receive-pack" is now more strict about
+ detecting breakage in the objects they receive over the wire.
+
+
+Fixes since v1.5.5
+------------------
+
+All of the fixes in v1.5.5 maintenance series are included in
+this release, unless otherwise noted.
+
+And there are too numerous small fixes to otherwise note here ;-)
--- /dev/null
+GIT v1.6.0.1 Release Notes
+==========================
+
+Fixes since v1.6.0
+------------------
+
+* "git diff --cc" did not honor content mangling specified by
+ gitattributes and core.autocrlf when reading from the work tree.
+
+* "git diff --check" incorrectly detected new trailing blank lines when
+ whitespace check was in effect.
+
+* "git for-each-ref" tried to dereference NULL when asked for '%(body)" on
+ a tag with a single incomplete line as its payload.
+
+* "git format-patch" peeked before the beginning of a string when
+ "format.headers" variable is empty (a misconfiguration).
+
+* "git help help" did not work correctly.
+
+* "git mailinfo" (hence "git am") was unhappy when MIME multipart message
+ contained garbage after the finishing boundary.
+
+* "git mailinfo" also was unhappy when the "From: " line only had a bare
+ e-mail address.
+
+* "git merge" did not refresh the index correctly when a merge resulted in
+ a fast-forward.
+
+* "git merge" did not resolve a truly trivial merges that can be done
+ without content level merges.
+
+* "git svn dcommit" to a repository with URL that has embedded usernames
+ did not work correctly.
+
+Contains other various documentation fixes.

+GIT v1.6.0.2 Release Notes
+==========================
+
+Fixes since v1.6.0.1
+--------------------
+
+* Installation on platforms that needs .exe suffix to git-* programs were
+ broken in 1.6.0.1.
+
+* Installation on filesystems without symbolic links support did not
+ work well.
+
+* In-tree documentations and test scripts now use "git foo" form to set a
+ better example, instead of the "git-foo" form (which is an acceptable
+ form if you have "PATH=$(git --exec-path):$PATH" in your script)
+
+* Many commands did not use the correct working tree location when used
+ with GIT_WORK_TREE environment settings.
+
+* Some systems need to use compatibility fnmatch and regex libraries
+ independent from each other; the compat/ area has been reorganized to
+ allow this.
+
+
+* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
+ a new line before the second line.
+
+* "git blame -c" did not exactly work like "git annotate" when range
+ boundaries are involved.
+
+* "git checkout file" when file is still unmerged checked out contents from
+ a random high order stage, which was confusing.
+
+* "git clone $there $here/" with extra trailing slashes after explicit
+ local directory name $here did not work as expected.
+
+* "git diff" on tracked contents with CRLF line endings did not drive "less"
+ intelligently when showing added or removed lines.
+
+* "git diff --dirstat -M" did not add changes in subdirectories up
+ correctly for renamed paths.
+
+* "git diff --cumulative" did not imply "--dirstat".
+
+* "git for-each-ref refs/heads/" did not work as expected.
+
+* "git gui" allowed users to feed patch without any context to be applied.
+
+* "git gui" botched parsing "diff" output when a line that begins with two
+ dashes and a space gets removed or a line that begins with two pluses
+ and a space gets added.
+
+* "git gui" translation updates and i18n fixes.
+
+* "git index-pack" is more careful against disk corruption while completing
+ a thin pack.
+
+* "git log -i --grep=pattern" did not ignore case; neither "git log -E
+ --grep=pattern" triggered extended regexp.
+
+* "git log --pretty="%ad" --date=short" did not use short format when
+ showing the timestamp.
+
+* "git log --author=author" match incorrectly matched with the
+ timestamp part of "author " line in commit objects.
+
+* "git log -F --author=author" did not work at all.
+
+* Build procedure for "git shell" that used stub versions of some
+ functions and globals was not understood by linkers on some platforms.
+
+* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
+ and refused to work until the user refreshed the index.
+
+* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
+ use of temporary files.
+
+* "git verify-pack -v" did not work correctly when given more than one
+ packfile.
+
+Also contains many documentation updates.

+GIT v1.6.0.3 Release Notes
+==========================
+
+Fixes since v1.6.0.2
+--------------------
+
+* "git archive --format=zip" did not honor core.autocrlf while
+ --format=tar did.
+
+* Continuing "git rebase -i" was very confused when the user left modified
+ files in the working tree while resolving conflicts.
+
+* Continuing "git rebase -i" was also very confused when the user left
+ some staged changes in the index after "edit".
+
+* "git rebase -i" now honors the pre-rebase hook, just like the
+ other rebase implementations "git rebase" and "git rebase -m".
+
+* "git rebase -i" incorrectly aborted when there is no commit to replay.
+
+* Behaviour of "git diff --quiet" was inconsistent with "diff --exit-code"
+ with the output redirected to /dev/null.
+
+* "git diff --no-index" on binary files no longer outputs a bogus
+ "diff --git" header line.
+
+* "git diff" hunk header patterns with multiple elements separated by LF
+ were not used correctly.
+
+* Hunk headers in "git diff" default to using extended regular
+ expressions, fixing some of the internal patterns on non-GNU
+ platforms.
+
+* New config "diff.*.xfuncname" exposes extended regular expressions
+ for user specified hunk header patterns.
+
+* "git gc" when ejecting otherwise unreachable objects from packfiles into
+ loose form leaked memory.
+
+* "git index-pack" was recently broken and mishandled objects added by
+ thin-pack completion processing under memory pressure.
+
+* "git index-pack" was recently broken and misbehaved when run from inside
+ .git/objects/pack/ directory.
+
+* "git stash apply sash@{1}" was fixed to error out. Prior versions
+ would have applied stash@{0} incorrectly.
+
+* "git stash apply" now offers a better suggestion on how to continue
+ if the working tree is currently dirty.
+
+* "git for-each-ref --format=%(subject)" fixed for commits with no
+ no newline in the message body.
+
+* "git remote" fixed to protect printf from user input.
+
+* "git remote show -v" now displays all URLs of a remote.
+
+* "git checkout -b branch" was confused when branch already existed.
+
+* "git checkout -q" once again suppresses the locally modified file list.
+
+* "git clone -q", "git fetch -q" asks remote side to not send
+ progress messages, actually making their output quiet.
+
+* Cross-directory renames are no longer used when creating packs. This
+ allows more graceful behavior on filesystems like sshfs.
+
+* Stale temporary files under $GIT_DIR/objects/pack are now cleaned up
+ automatically by "git prune".
+
+* "git merge" once again removes directories after the last file has
+ been removed from it during the merge.
+
+* "git merge" did not allocate enough memory for the structure itself when
+ enumerating the parents of the resulting commit.
+
+* "git blame -C -C" no longer segfaults while trying to pass blame if
+ it encounters a submodule reference.
+
+* "git rm" incorrectly claimed that you have local modifications when a
+ path was merely stat-dirty.
+
+* "git svn" fixed to display an error message when 'set-tree' failed,
+ instead of a Perl compile error.
+
+* "git submodule" fixed to handle checking out a different commit
+ than HEAD after initializing the submodule.
+
+* The "git commit" error message when there are still unmerged
+ files present was clarified to match "git write-tree".
+
+* "git init" was confused when core.bare or core.sharedRepository are set
+ in system or user global configuration file by mistake. When --bare or
+ --shared is given from the command line, these now override such
+ settings made outside the repositories.
+
+* Some segfaults due to uncaught NULL pointers were fixed in multiple
+ tools such as apply, reset, update-index.
+
+* Solaris builds now default to OLD_ICONV=1 to avoid compile warnings;
+ Solaris 8 does not define NEEDS_LIBICONV by default.
+
+* "Git.pm" tests relied on unnecessarily more recent version of Perl.
+
+* "gitweb" triggered undef warning on commits without log messages.
+
+* "gitweb" triggered undef warnings on missing trees.
+
+* "gitweb" now removes PATH_INFO from its URLs so users don't have
+ to manually set the URL in the gitweb configuration.
+
+* Bash completion removed support for legacy "git-fetch", "git-push"
+ and "git-pull" as these are no longer installed. Dashless form
+ ("git fetch") is still however supported.
+
+Many other documentation updates.
--- /dev/null
+GIT v1.6.0.4 Release Notes
+==========================
+
+Fixes since v1.6.0.3
+--------------------
+
+* 'git add -p' said "No changes" when only binary files were changed.
+
+* 'git archive' did not work correctly in bare repositories.
+
+* 'git checkout -t -b newbranch' when you are on detached HEAD was broken.
+
+* when we refuse to detect renames because there are too many new or
+ deleted files, 'git diff' did not say how many there are.
+
+* 'git push --mirror' tried and failed to push the stash; there is no
+ point in sending it to begin with.
+
+* 'git push' did not update the remote tracking reference if the corresponding
+ ref on the remote end happened to be already up to date.
+
+* 'git pull $there $branch:$current_branch' did not work when you were on
+ a branch yet to be born.
+
+* when giving up resolving a conflicted merge, 'git reset --hard' failed
+ to remove new paths from the working tree.
+
+* 'git send-email' had a small fd leak while scanning directory.
+
+* 'git status' incorrectly reported a submodule directory as an untracked
+ directory.
+
+* 'git svn' used deprecated 'git-foo' form of subcommand invocation.
+
+* 'git update-ref -d' to remove a reference did not honor --no-deref option.
+
+* Plugged small memleaks here and there.
+
+* Also contains many documentation updates.
--- /dev/null
+GIT v1.6.0.5 Release Notes
+==========================
+
+Fixes since v1.6.0.4
+--------------------
+
+* "git checkout" used to crash when your HEAD was pointing at a deleted
+ branch.
+
+* "git checkout" from an un-checked-out state did not allow switching out
+ of the current branch.
+
+* "git diff" always allowed GIT_EXTERNAL_DIFF and --no-ext-diff was no-op for
+ the command.
+
+* Giving 3 or more tree-ish to "git diff" is supposed to show the combined
+ diff from second and subsequent trees to the first one, but the order was
+ screwed up.
+
+* "git fast-export" did not export all tags.
+
+* "git ls-files --with-tree=<tree>" did not work with options other
+ than -c, most notably with -m.
+
+* "git pack-objects" did not make its best effort to honor --max-pack-size
+ option when a single first object already busted the given limit and
+ placed many objects in a single pack.
+
+* "git-p4" fast import frontend was too eager to trigger its keyword expansion
+ logic, even on a keyword-looking string that does not have closing '$' on the
+ same line.
+
+* "git push $there" when the remote $there is defined in $GIT_DIR/branches/$there
+ behaves more like what cg-push from Cogito used to work.
+
+* when giving up resolving a conflicted merge, "git reset --hard" failed
+ to remove new paths from the working tree.
+
+* "git tag" did not complain when given mutually incompatible set of options.
+
+* The message constructed in the internal editor was discarded when "git
+ tag -s" failed to sign the message, which was often caused by the user
+ not configuring GPG correctly.
+
+* "make check" cannot be run without sparse; people may have meant to say
+ "make test" instead, so suggest that.
+
+* Internal diff machinery had a corner case performance bug that choked on
+ a large file with many repeated contents.
+
+* "git repack" used to grab objects out of packs marked with .keep
+ into a new pack.
+
+* Many unsafe call to sprintf() style varargs functions are corrected.
+
+* Also contains quite a few documentation updates.
--- /dev/null
+GIT v1.6.0.6 Release Notes
+==========================
+
+Fixes since 1.6.0.5
+-------------------
+
+ * "git fsck" had a deep recursion that wasted stack space.
+
+ * "git fast-export" and "git fast-import" choked on an old style
+ annotated tag that lack the tagger information.
+
+ * "git mergetool -- file" did not correctly skip "--" marker that
+ signals the end of options list.
+
+ * "git show $tag" segfaulted when an annotated $tag pointed at a
+ nonexistent object.
+
+ * "git show 2>error" when the standard output is automatically redirected
+ to the pager redirected the standard error to the pager as well; there
+ was no need to.
+
+ * "git send-email" did not correctly handle list of addresses when
+ they had quoted comma (e.g. "Lastname, Givenname" <mail@addre.ss>).
+
+ * Logic to discover branch ancestry in "git svn" was unreliable when
+ the process to fetch history was interrupted.
+
+ * Removed support for an obsolete gitweb request URI, whose
+ implementation ran "git diff" Porcelain, instead of using plumbing,
+ which would have run an external diff command specified in the
+ repository configuration as the gitweb user.
+
+Also contains numerous documentation typofixes.
--- /dev/null
+GIT v1.6.0 Release Notes
+========================
+
+User visible changes
+--------------------
+
+With the default Makefile settings, most of the programs are now
+installed outside your $PATH, except for "git", "gitk" and
+some server side programs that need to be accessible for technical
+reasons. Invoking a git subcommand as "git-xyzzy" from the command
+line has been deprecated since early 2006 (and officially announced in
+1.5.4 release notes); use of them from your scripts after adding
+output from "git --exec-path" to the $PATH is still supported in this
+release, but users are again strongly encouraged to adjust their
+scripts to use "git xyzzy" form, as we will stop installing
+"git-xyzzy" hardlinks for built-in commands in later releases.
+
+An earlier change to page "git status" output was overwhelmingly unpopular
+and has been reverted.
+
+Source changes needed for porting to MinGW environment are now all in the
+main git.git codebase.
+
+By default, packfiles created with this version uses delta-base-offset
+encoding introduced in v1.4.4. Pack idx files are using version 2 that
+allows larger packs and added robustness thanks to its CRC checking,
+introduced in v1.5.2 and v1.4.4.5. If you want to keep your repositories
+backwards compatible past these versions, set repack.useDeltaBaseOffset
+to false or pack.indexVersion to 1, respectively.
+
+We used to prevent sample hook scripts shipped in templates/ from
+triggering by default by relying on the fact that we install them as
+unexecutable, but on some filesystems, this approach does not work.
+They are now shipped with ".sample" suffix. If you want to activate
+any of these samples as-is, rename them to drop the ".sample" suffix,
+instead of running "chmod +x" on them. For example, you can rename
+hooks/post-update.sample to hooks/post-update to enable the sample
+hook that runs update-server-info, in order to make repositories
+friendly to dumb protocols (i.e. HTTP).
+
+GIT_CONFIG, which was only documented as affecting "git config", but
+actually affected all git commands, now only affects "git config".
+GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
+not different from GIT_CONFIG in a useful way, is removed.
+
+The ".dotest" temporary area "git am" and "git rebase" use is now moved
+inside the $GIT_DIR, to avoid mistakes of adding it to the project by
+accident.
+
+An ancient merge strategy "stupid" has been removed.
+
+
+Updates since v1.5.6
+--------------------
+
+(subsystems)
+
+* git-p4 in contrib learned "allowSubmit" configuration to control on
+ which branch to allow "submit" subcommand.
+
+* git-gui learned to stage changes per-line.
+
+(portability)
+
+* Changes for MinGW port have been merged, thanks to Johannes Sixt and
+ gangs.
+
+* Sample hook scripts shipped in templates/ are now suffixed with
+ *.sample.
+
+* perl's in-place edit (-i) does not work well without backup files on Windows;
+ some tests are rewritten to cope with this.
+
+(documentation)
+
+* Updated howto/update-hook-example
+
+* Got rid of usage of "git-foo" from the tutorial and made typography
+ more consistent.
+
+* Disambiguating "--" between revs and paths is finally documented.
+
+(performance, robustness, sanity etc.)
+
+* index-pack used too much memory when dealing with a deep delta chain.
+ This has been optimized.
+
+* reduced excessive inlining to shrink size of the "git" binary.
+
+* verify-pack checks the object CRC when using version 2 idx files.
+
+* When an object is corrupt in a pack, the object became unusable even
+ when the same object is available in a loose form, We now try harder to
+ fall back to these redundant objects when able. In particular, "git
+ repack -a -f" can be used to fix such a corruption as long as necessary
+ objects are available.
+
+* Performance of "git-blame -C -C" operation is vastly improved.
+
+* git-clone does not create refs in loose form anymore (it behaves as
+ if you immediately ran git-pack-refs after cloning). This will help
+ repositories with insanely large number of refs.
+
+* core.fsyncobjectfiles configuration can be used to ensure that the loose
+ objects created will be fsync'ed (this is only useful on filesystems
+ that does not order data writes properly).
+
+* "git commit-tree" plumbing can make Octopus with more than 16 parents.
+ "git commit" has been capable of this for quite some time.
+
+(usability, bells and whistles)
+
+* even more documentation pages are now accessible via "man" and "git help".
+
+* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
+ the discovery process of the toplevel of working tree; this may be useful
+ when you are working in a slow network disk and are outside any working tree,
+ as bash-completion and "git help" may still need to run in these places.
+
+* By default, stash entries never expire. Set reflogexpire in [gc
+ "refs/stash"] to a reasonable value to get traditional auto-expiration
+ behaviour back
+
+* Longstanding latency issue with bash completion script has been
+ addressed. This will need to be backmerged to 'maint' later.
+
+* pager.<cmd> configuration variable can be used to enable/disable the
+ default paging behaviour per command.
+
+* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
+ manually.
+
+* git-am records the original tip of the branch in ORIG_HEAD before it
+ starts applying patches.
+
+* git-apply can handle a patch that touches the same path more than once
+ much better than before.
+
+* git-apply can be told not to trust the line counts recorded in the input
+ patch but recount, with the new --recount option.
+
+* git-apply can be told to apply a patch to a path deeper than what the
+ patch records with --directory option.
+
+* git-archive can be told to omit certain paths from its output using
+ export-ignore attributes.
+
+* git-archive uses the zlib default compression level when creating
+ zip archive.
+
+* git-archive's command line options --exec and --remote can take their
+ parameters as separate command line arguments, similar to other commands.
+ IOW, both "--exec=path" and "--exec path" are now supported.
+
+* With -v option, git-branch describes the remote tracking statistics
+ similar to the way git-checkout reports by how many commits your branch
+ is ahead/behind.
+
+* git-branch's --contains option used to always require a commit parameter
+ to limit the branches with; it now defaults to list branches that
+ contains HEAD if this parameter is omitted.
+
+* git-branch's --merged and --no-merged option used to always limit the
+ branches relative to the HEAD, but they can now take an optional commit
+ argument that is used in place of HEAD.
+
+* git-bundle can read the revision arguments from the standard input.
+
+* git-cherry-pick can replay a root commit now.
+
+* git-clone can clone from a remote whose URL would be rewritten by
+ configuration stored in $HOME/.gitconfig now.
+
+* "git-clone --mirror" is a handy way to set up a bare mirror repository.
+
+* git-cvsserver learned to respond to "cvs co -c".
+
+* git-diff --check now checks leftover merge conflict markers.
+
+* "git-diff -p" learned to grab a better hunk header lines in
+ BibTex, Pascal/Delphi, and Ruby files and also pays attention to
+ chapter and part boundary in TeX documents.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+ it has branch 'foo/bar', it refuses to lose the existing remote tracking
+ branch and its reflog. The error message has been improved to suggest
+ pruning the remote if the user wants to proceed and get the latest set
+ of branches from the remote, including such 'foo/bar'.
+
+* fast-export learned to export and import marks file; this can be used to
+ interface with fast-import incrementally.
+
+* fast-import and fast-export learned to export and import gitlinks.
+
+* "gitk" left background process behind after being asked to dig very deep
+ history and the user killed the UI; the process is killed when the UI goes
+ away now.
+
+* git-rebase records the original tip of branch in ORIG_HEAD before it is
+ rewound.
+
+* "git rerere" can be told to update the index with auto-reused resolution
+ with rerere.autoupdate configuration variable.
+
+* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
+ family. These notations are available in gitk as well, because the gitk
+ command internally uses rev-parse to interpret its arguments.
+
+* git-rev-list learned --children option to show child commits it
+ encountered during the traversal, instead of showing parent commits.
+
+* git-send-mail can talk not just over SSL but over TLS now.
+
+* git-shortlog honors custom output format specified with "--pretty=format:".
+
+* "git-stash save" learned --keep-index option. This lets you stash away the
+ local changes and bring the changes staged in the index to your working
+ tree for examination and testing.
+
+* git-stash also learned branch subcommand to create a new branch out of
+ stashed changes.
+
+* git-status gives the remote tracking statistics similar to the way
+ git-checkout reports by how many commits your branch is ahead/behind.
+
+* "git-svn dcommit" is now aware of auto-props setting the subversion user
+ has.
+
+* You can tell "git status -u" to even more aggressively omit checking
+ untracked files with --untracked-files=no.
+
+* Original SHA-1 value for "update-ref -d" is optional now.
+
+* Error codes from gitweb are made more descriptive where possible, rather
+ than "403 forbidden" as we used to issue everywhere.
+
+(internal)
+
+* git-merge has been reimplemented in C.
+
+
+Fixes since v1.5.6
+------------------
+
+All of the fixes in v1.5.6 maintenance series are included in
+this release, unless otherwise noted.
+
+ * git-clone ignored its -u option; the fix needs to be backported to
+ 'maint';
+
+ * git-mv used to lose the distinction between changes that are staged
+ and that are only in the working tree, by staging both in the index
+ after moving such a path.
+
+ * "git-rebase -i -p" rewrote the parents to wrong ones when amending
+ (either edit or squash) was involved, and did not work correctly
+ when fast forwarding.

+GIT v1.6.1.1 Release Notes
+==========================
+
+Fixes since v1.6.1
+------------------
+
+* "git add frotz/nitfol" when "frotz" is a submodule should have errored
+ out, but it didn't.
+
+* "git apply" took file modes from the patch text and updated the mode
+ bits of the target tree even when the patch was not about mode changes.
+
+* "git bisect view" on Cygwin did not launch gitk
+
+* "git checkout $tree" did not trigger an error.
+
+* "git commit" tried to remove COMMIT_EDITMSG from the work tree by mistake.
+
+* "git describe --all" complained when a commit is described with a tag,
+ which was nonsense.
+
+* "git diff --no-index --" did not trigger no-index (aka "use git-diff as
+ a replacement of diff on untracked files") behaviour.
+
+* "git format-patch -1 HEAD" on a root commit failed to produce patch
+ text.
+
+* "git fsck branch" did not work as advertised; instead it behaved the same
+ way as "git fsck".
+
+* "git log --pretty=format:%s" did not handle a multi-line subject the
+ same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
+
+* "git daemon", and "git merge-file" are more careful when freopen fails
+ and barf, instead of going on and writing to unopened filehandle.
+
+* "git http-push" did not like some RFC 4918 compliant DAV server
+ responses.
+
+* "git merge -s recursive" mistakenly overwritten an untracked file in the
+ work tree upon delete/modify conflict.
+
+* "git merge -s recursive" didn't leave the index unmerged for entries with
+ rename/delete conflicts.
+
+* "git merge -s recursive" clobbered untracked files in the work tree.
+
+* "git mv -k" with more than one erroneous paths misbehaved.
+
+* "git read-tree -m -u" hence branch switching incorrectly lost a
+ subdirectory in rare cases.
+
+* "git rebase -i" issued an unnecessary error message upon a user error of
+ marking the first commit to be "squash"ed.
+
+* "git shortlog" did not format a commit message with multi-line
+ subject correctly.
+
+Many documentation updates.
--- /dev/null
+GIT v1.6.1.2 Release Notes
+==========================
+
+Fixes since v1.6.1.1
+--------------------
+
+* The logic for rename detection in internal diff used by commands like
+ "git diff" and "git blame" has been optimized to avoid loading the same
+ blob repeatedly.
+
+* We did not allow writing out a blob that is larger than 2GB for no good
+ reason.
+
+* "git format-patch -o $dir", when $dir is a relative directory, used it
+ as relative to the root of the work tree, not relative to the current
+ directory.
+
+* v1.6.1 introduced an optimization for "git push" into a repository (A)
+ that borrows its objects from another repository (B) to avoid sending
+ objects that are available in repository B, when they are not yet used
+ by repository A. However the code on the "git push" sender side was
+ buggy and did not work when repository B had new objects that are not
+ known by the sender. This caused pushing into a "forked" repository
+ served by v1.6.1 software using "git push" from v1.6.1 sometimes did not
+ work. The bug was purely on the "git push" sender side, and has been
+ corrected.
+
+* "git status -v" did not paint its diff output in colour even when
+ color.ui configuration was set.
+
+* "git ls-tree" learned --full-tree option to help Porcelain scripts that
+ want to always see the full path regardless of the current working
+ directory.
+
+* "git grep" incorrectly searched in work tree paths even when they are
+ marked as assume-unchanged. It now searches in the index entries.
+
+* "git gc" with no grace period needlessly ejected packed but unreachable
+ objects in their loose form, only to delete them right away.
--- /dev/null
+GIT v1.6.1.3 Release Notes
+==========================
+
+Fixes since v1.6.1.2
+--------------------
+
+* "git diff --binary | git apply" pipeline did not work well when
+ a binary blob is changed to a symbolic link.
+
+* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
+ not work as expected.
+
+* "git grep" did not pass the -I (ignore binary) option when
+ calling out an external grep program.
+
+* "git log" and friends include HEAD to the set of starting points
+ when --all is given. This makes a difference when you are not
+ on any branch.
+
+* "git mv" to move an untracked file to overwrite a tracked
+ contents misbehaved.
+
+* "git merge -s octopus" with many potential merge bases did not
+ work correctly.
+
+* RPM binary package installed the html manpages in a wrong place.
+
+Also includes minor documentation fixes and updates.

+GIT v1.6.1.4 Release Notes
+==========================
+
+Fixes since v1.6.1.3
+--------------------
+
+* .gitignore learned to handle backslash as a quoting mechanism for
+ comment introduction character "#".
+ This fix was first merged to 1.6.2.1.
+
+* "git fast-export" produced wrong output with some parents missing from
+ commits, when the history is clock-skewed.
+
+* "git fast-import" sometimes failed to read back objects it just wrote
+ out and aborted, because it failed to flush stale cached data.
+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+ deciding to descend into a subdirectory but they did not match the
+ individual paths correctly. This caused pathspecs "abc/d ab" to match
+ "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+ and then "ab" incorrectly matched "abc/0" when it shouldn't).
+ This fix was first merged to 1.6.2.3.
+
+* import-zips script (in contrib) did not compute the common directory
+ prefix correctly.
+ This fix was first merged to 1.6.2.2.
+
+* "git init" segfaulted when given an overlong template location via
+ the --template= option.
+ This fix was first merged to 1.6.2.4.
+
+* "git repack" did not error out when necessary object was missing in the
+ repository.
+
+* git-repack (invoked from git-gc) did not work as nicely as it should in
+ a repository that borrows objects from neighbours via alternates
+ mechanism especially when some packs are marked with the ".keep" flag
+ to prevent them from being repacked.
+ This fix was first merged to 1.6.2.3.
+
+Also includes minor documentation fixes and updates.

+git shortlog --no-merges v1.6.1.3..
--- /dev/null
+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output. This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command. We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+ can run gitk from its blame view.
+
+* Various git-gui updates including updated translations.
+
+* Various gitweb updates from repo.or.cz installation.
+
+* Updates to emacs bindings.
+
+(portability)
+
+* A few test scripts used nonportable "grep" that did not work well on
+ some platforms, e.g. Solaris.
+
+* Sample pre-auto-gc script has OS X support.
+
+* Makefile has support for (ancient) FreeBSD 4.9.
+
+(performance)
+
+* Many operations that are lstat(3) heavy can be told to pre-execute
+ necessary lstat(3) in parallel before their main operations, which
+ potentially gives much improved performance for cold-cache cases or in
+ environments with weak metadata caching (e.g. NFS).
+
+* The underlying diff machinery to produce textual output has been
+ optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+ can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+ refs has been optimized.
+
+* Cygwin port uses native stat/lstat implementations when applicable,
+ which leads to improved performance.
+
+* "git push" pays attention to alternate repositories to avoid sending
+ unnecessary objects.
+
+* "git svn" can rebuild an out-of-date rev_map file.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+ you might have meant to say. help.autocorrect configuration can be set
+ to a non-zero value to accept the suggestion when git can uniquely
+ guess.
+
+* The packfile machinery hopefully is more robust when dealing with
+ corrupt packs if redundant objects involved in the corruption are
+ available elsewhere.
+
+* "git add -N path..." adds the named paths as an empty blob, so that
+ subsequent "git diff" will show a diff as if they are creation events.
+
+* "git add" gained a built-in synonym for people who want to say "stage
+ changes" instead of "add contents to the staging area" which amounts
+ to the same thing.
+
+* "git apply" learned --include=paths option, similar to the existing
+ --exclude=paths option.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+ merge base first when good is not a strict ancestor of bad.
+
+* "git bisect skip" can take a range of commits.
+
+* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
+ by default.
+
+* "git check-attr --stdin" can check attributes for multiple paths.
+
+* "git checkout --track origin/hack" used to be a syntax error. It now
+ DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+ said "git checkout --track -b hack origin/hack".
+
+* "git checkout --ours/--theirs" can be used to check out one side of a
+ conflicting merge during conflict resolution.
+
+* "git checkout -m" can be used to recreate the initial conflicted state
+ during conflict resolution.
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git clone" learned to be verbose with -v
+
+* "git commit --author=$name" can look up author name from existing
+ commits.
+
+* output from "git commit" has been reworded in a more concise and yet
+ more informative way.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+ their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git daemon" exports REMOTE_ADDR to record client address, so that
+ spawned programs can act differently on it.
+
+* "git describe --tags" favours closer lightweight tags than farther
+ annotated tags now.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+ configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python,
+ HTML and ObjC contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+ being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git diff" learned --dirstat-by-file to count changed files, not number
+ of lines, when summarizing the global picture.
+
+* "git diff" learned "textconv" filters --- a binary or hard-to-read
+ contents can be munged into human readable form and the difference
+ between the results of the conversion can be viewed (obviously this
+ cannot produce a patch that can be applied, so this is disabled in
+ format-patch among other things).
+
+* "--cached" option to "git diff has an easier to remember synonym "--staged",
+ to ask "what is the difference between the given commit and the
+ contents staged in the index?"
+
+* "git for-each-ref" learned "refname:short" token that gives an
+ unambiguously abbreviated refname.
+
+* Auto-numbering of the subject lines is the default for "git
+ format-patch" now.
+
+* "git grep" learned to accept -z similar to GNU grep.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+ using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+ completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+ status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+ "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log" learned "--source" to show what ref each commit was reached
+ from.
+
+* "git log" also learned "--simplify-by-decoration" to show the
+ birds-eye-view of the topology of the history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+ names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+ noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+ command "git-merge-$strategy" on your $PATH.
+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
+ "-q"uietly.
+
+* "git push" can be told to reject deletion of refs with receive.denyDeletes
+ configuration.
+
+* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
+
+* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+ refs/heads/branch".
+
+* "git remote show $remote" lists remote branches one-per-line now.
+
+* "git send-email" can be given revision range instead of files and
+ maildirs on the command line, and automatically runs format-patch to
+ generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+ out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+ recorded in submodule directories from the toplevel .gitmodules file.
+
+* "git svn branch" can create new branches on the other end.
+
+* "gitweb" can use more saner PATH_INFO based URL.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+ correct gitattributes processing can be done while hashing contents
+ stored in a temporary file.
+
+* various callers of git-merge-recursive avoid forking it as an external
+ process.
+
+* Git class defined in "Git.pm" can be subclasses a bit more easily.
+
+* We used to link GNU regex library as a compatibility layer for some
+ platforms, but it turns out it is not necessary on most of them.
+
+* Some path handling routines used fixed number of buffers used alternately
+ but depending on the call depth, this arrangement led to hard to track
+ bugs. This issue is being addressed.
+
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* Porcelains implemented as shell scripts were utterly confused when you
+ entered to a subdirectory of a work tree from sideways, following a
+ symbolic link (this may need to be backported to older releases later).
+
+* Tracking symbolic links would work better on filesystems whose lstat()
+ returns incorrect st_size value for them.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+ is a tracked symlink that points at a directory D that has a path F in
+ it (we still need to fix a similar nonsense when S is a submodule and F
+ is a path in it).
+
+* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
+ --3way options given from the command line initially.
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+ but we dropped support for such a use case long time ago. This has
+ been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git http-push" did not understand URI scheme other than opaquelocktoken
+ when acquiring a lock from the server (this may need to be backported to
+ older releases later).
+
+* After "git rebase -p" stopped with conflicts while replaying a merge,
+ "git rebase --continue" did not work (may need to be backported to older
+ releases).
+
+* "git revert" records relative to which parent a revert was made when
+ reverting a merge. Together with new documentation that explains issues
+ around reverting a merge and merging from the updated branch later, this
+ hopefully will reduce user confusion (this may need to be backported to
+ older releases later).
+
+* "git rm --cached" used to allow an empty blob that was added earlier to
+ be removed without --force, even when the file in the work tree has
+ since been modified.
+
+* "git push --tags --all $there" failed with generic usage message without
+ telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+ timestamp part, exposing internal implementation detail. Also these did
+ not work with --fixed-strings match at all.
+
+* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
+ correctly.

+------------------
+
+* .gitignore learned to handle backslash as a quoting mechanism for

+
+* timestamp output in --date=relative mode used to display timestamps that

+GIT v1.6.2.2 Release Notes
+==========================
+
+Fixes since v1.6.2.1
+--------------------
+
+* A longstanding confusing description of what --pickaxe option of
+ git-diff does has been clarified in the documentation.
+
+* "git-blame -S" did not quite work near the commits that were given
+ on the command line correctly.
+
+* "git diff --pickaxe-regexp" did not count overlapping matches
+ correctly.
+
+* "git diff" did not feed files in work-tree representation to external
+ diff and textconv.
+
+* "git-fetch" in a repository that was not cloned from anywhere said
+ it cannot find 'origin', which was hard to understand for new people.
+
+* "git-format-patch --numbered-files --stdout" did not have to die of
+ incompatible options; it now simply ignores --numbered-files as no files
+ are produced anyway.
+
+* "git-ls-files --deleted" did not work well with GIT_DIR&GIT_WORK_TREE.
+
+* "git-read-tree A B C..." without -m option has been broken for a long
+ time.
+
+* git-send-email ignored --in-reply-to when --no-thread was given.
+
+* 'git-submodule add' did not tolerate extra slashes and ./ in the path it
+ accepted from the command line; it now is more lenient.
+
+* git-svn misbehaved when the project contained a path that began with
+ two dashes.
+
+* import-zips script (in contrib) did not compute the common directory
+ prefix correctly.
+
+* miscompilation of negated enum constants by old gcc (2.9) affected the
+ codepaths to spawn subprocesses.
+
+Many small documentation updates are included as well.

+GIT v1.6.2.3 Release Notes
+==========================
+
+Fixes since v1.6.2.2
+--------------------
+
+* Setting an octal mode value to core.sharedrepository configuration to
+ restrict access to the repository to group members did not work as
+ advertised.
+
+* A fairly large and trivial memory leak while rev-list shows list of
+ reachable objects has been identified and plugged.
+
+* "git-commit --interactive" did not abort when underlying "git-add -i"
+ signaled a failure.
+
+* git-repack (invoked from git-gc) did not work as nicely as it should in
+ a repository that borrows objects from neighbours via alternates
+ mechanism especially when some packs are marked with the ".keep" flag
+ to prevent them from being repacked.
+
+Many small documentation updates are included as well.
--- /dev/null
+GIT v1.6.2.4 Release Notes
+==========================
+
+Fixes since v1.6.2.3
+--------------------
+
+* The configuration parser had a buffer overflow while parsing an overlong
+ value.
+
+* pruning reflog entries that are unreachable from the tip of the ref
+ during "git reflog prune" (hence "git gc") was very inefficient.
+
+* "git-add -p" lacked a way to say "q"uit to refuse staging any hunks for
+ the remaining paths. You had to say "d" and then ^C.
+
+* "git-checkout <tree-ish> <submodule>" did not update the index entry at
+ the named path; it now does.
+
+* "git-fast-export" choked when seeing a tag that does not point at commit.
+
+* "git init" segfaulted when given an overlong template location via
+ the --template= option.
+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+ deciding to descend into a subdirectory but they did not match the
+ individual paths correctly. This caused pathspecs "abc/d ab" to match
+ "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+ and then "ab" incorrectly matched "abc/0" when it shouldn't).
+
+* "git-merge-recursive" was broken when a submodule entry was involved in
+ a criss-cross merge situation.
+
+Many small documentation updates are included as well.

+
+* "git apply" mishandled if you fed a git generated patch that renames
+ file A to B and file B to A at the same time.
+
+* "git diff -c -p" (and "diff --cc") did not expect to see submodule

+
+* "git grep -e '('" segfaulted, instead of diagnosing a mismatched
+ parentheses error.
+
+* "git fetch" generated packs with offset-delta encoding when both ends of
+ the connection are capable of producing one; this cannot be read by
+ ancient git and the user should be able to disable this by setting

+GIT v1.6.2 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default. You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing. Please refer to:
+
+ http://git.or.cz/gitwiki/GitFaq#non-bare
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007

+for more details on the reason why this change is needed and the
+transition plan.

+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning. You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+* git-svn updates.
+
+* gitweb updates, including a new patch view and RSS/Atom feed
+ improvements.
+
+* (contrib/emacs) git.el now has commands for checking out a branch,
+ creating a branch, cherry-picking and reverting commits; vc-git.el
+ is not shipped with git anymore (it is part of official Emacs).
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+ version.
+
+(usability, bells and whistles)
+
+* automatic typo correction works on aliases as well
+
+* @{-1} is a way to refer to the last branch you were on. This is
+ accepted not only where an object name is expected, but anywhere
+ a branch name is expected and acts as if you typed the branch name.
+ E.g. "git branch --track mybranch @{-1}", "git merge @{-1}", and
+ "git rev-parse --symbolic-full-name @{-1}" would work as expected.
+
+* When refs/remotes/origin/HEAD points at a remote tracking branch that
+ has been pruned away, many git operations issued warning when they
+ internally enumerated the refs. We now warn only when you say "origin"
+ to refer to that pruned branch.
+
+* The location of .mailmap file can be configured, and its file format was
+ enhanced to allow mapping an incorrect e-mail field as well.
+
+* "git add -p" learned 'g'oto action to jump directly to a hunk.
+
+* "git add -p" learned to find a hunk with given text with '/'.
+
+* "git add -p" optionally can be told to work with just the command letter
+ without Enter.
+
+* when "git am" stops upon a patch that does not apply, it shows the
+ title of the offending patch.
+
+* "git am --directory=<dir>" and "git am --reject" passes these options
+ to underlying "git apply".
+
+* "git am" learned --ignore-date option.
+
+* "git blame" aligns author names better when they are spelled in
+ non US-ASCII encoding.
+
+* "git clone" now makes its best effort when cloning from an empty
+ repository to set up configuration variables to refer to the remote
+ repository.
+
+* "git checkout -" is a shorthand for "git checkout @{-1}".
+
+* "git cherry" defaults to whatever the current branch is tracking (if
+ exists) when the <upstream> argument is not given.
+
+* "git cvsserver" can be told not to add extra "via git-CVS emulator" to
+ the commit log message it serves via gitcvs.commitmsgannotation
+ configuration.
+
+* "git cvsserver" learned to handle 'noop' command some CVS clients seem
+ to expect to work.
+
+* "git diff" learned a new option --inter-hunk-context to coalesce close
+ hunks together and show context between them.
+
+* The definition of what constitutes a word for "git diff --color-words"
+ can be customized via gitattributes, command line or a configuration.
+
+* "git diff" learned --patience to run "patience diff" algorithm.
+
+* "git filter-branch" learned --prune-empty option that discards commits
+ that do not change the contents.
+
+* "git fsck" now checks loose objects in alternate object stores, instead
+ of misreporting them as missing.
+
+* "git gc --prune" was resurrected to allow "git gc --no-prune" and
+ giving non-default expiration period e.g. "git gc --prune=now".
+
+* "git grep -w" and "git grep" for fixed strings have been optimized.
+
+* "git mergetool" learned -y(--no-prompt) option to disable prompting.
+
+* "git rebase -i" can transplant a history down to root to elsewhere
+ with --root option.
+
+* "git reset --merge" is a new mode that works similar to the way
+ "git checkout" switches branches, taking the local changes while
+ switching to another commit.
+
+* "git submodule update" learned --no-fetch option.
+
+* "git tag" learned --contains that works the same way as the same option
+ from "git branch".
+
+
+Fixes since v1.6.1
+------------------
+
+All of the fixes in v1.6.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.1.X series.
+
+* "git-add sub/file" when sub is a submodule incorrectly added the path to
+ the superproject.
+
+* "git bundle" did not exclude annotated tags even when a range given
+ from the command line wanted to.
+
+* "git filter-branch" unnecessarily refused to work when you had
+ checked out a different commit from what is recorded in the superproject
+ index in a submodule.
+
+* "git filter-branch" incorrectly tried to update a nonexistent work tree
+ at the end when it is run in a bare repository.
+
+* "git gc" did not work if your repository was created with an ancient git
+ and never had any pack files in it before.
+
+* "git mergetool" used to ignore autocrlf and other attributes
+ based content rewriting.
+
+* branch switching and merges had a silly bug that did not validate
+ the correct directory when making sure an existing subdirectory is
+ clean.
+
+* "git -p cmd" when cmd is not a built-in one left the display in funny state
+ when killed in the middle.
--- /dev/null
+GIT v1.6.3.1 Release Notes
+==========================
+
+Fixes since v1.6.3
+------------------
+
+* "git checkout -b new-branch" with a staged change in the index
+ incorrectly primed the in-index cache-tree, resulting a wrong tree
+ object to be written out of the index. This is a grave regression
+ since the last 1.6.2.X maintenance release.
--- /dev/null
+GIT v1.6.3.2 Release Notes
+==========================
+
+Fixes since v1.6.3.1
+--------------------
+
+ * A few codepaths picked up the first few bytes from an sha1[] by
+ casting the (char *) pointer to (int *); GCC 4.4 did not like this,
+ and aborted compilation.
+
+ * Some unlink(2) failures went undiagnosed.
+
+ * The "recursive" merge strategy misbehaved when faced rename/delete
+ conflicts while coming up with an intermediate merge base.
+
+ * The low-level merge algorithm did not handle a degenerate case of
+ merging a file with itself using itself as the common ancestor
+ gracefully. It should produce the file itself, but instead
+ produced an empty result.
+
+ * GIT_TRACE mechanism segfaulted when tracing a shell-quoted aliases.
+
+ * OpenBSD also uses st_ctimspec in "struct stat", instead of "st_ctim".
+
+ * With NO_CROSS_DIRECTORY_HARDLINKS, "make install" can be told not to
+ create hardlinks between $(gitexecdir)/git-$builtin_commands and
+ $(bindir)/git.
+
+ * command completion code in bash did not reliably detect that we are
+ in a bare repository.
+
+ * "git add ." in an empty directory complained that pathspec "." did not
+ match anything, which may be technically correct, but not useful. We
+ silently make it a no-op now.
+
+ * "git add -p" (and "patch" action in "git add -i") was broken when
+ the first hunk that adds a line at the top was split into two and
+ both halves are marked to be used.
+
+ * "git blame path" misbehaved at the commit where path became file
+ from a directory with some files in it.
+
+ * "git for-each-ref" had a segfaulting bug when dealing with a tag object
+ created by an ancient git.
+
+ * "git format-patch -k" still added patch numbers if format.numbered
+ configuration was set.
+
+ * "git grep --color ''" did not terminate. The command also had
+ subtle bugs with its -w option.
+
+ * http-push had a small use-after-free bug.
+
+ * "git push" was converting OFS_DELTA pack representation into less
+ efficient REF_DELTA representation unconditionally upon transfer,
+ making the transferred data unnecessarily larger.
+
+ * "git remote show origin" segfaulted when origin was still empty.
+
+Many other general usability updates around help text, diagnostic messages
+and documentation are included as well.
--- /dev/null
+GIT v1.6.3.3 Release Notes
+==========================
+
+Fixes since v1.6.3.2
+--------------------
+
+ * "git archive" running on Cygwin can get stuck in an infinite loop.
+
+ * "git daemon" did not correctly parse the initial line that carries
+ virtual host request information.
+
+ * "git diff --textconv" leaked memory badly when the textconv filter
+ errored out.
+
+ * The built-in regular expressions to pick function names to put on
+ hunk header lines for java and objc were very inefficiently written.
+
+ * in certain error situations git-fetch (and git-clone) on Windows didn't
+ detect connection abort and ended up waiting indefinitely.
+
+ * import-tars script (in contrib) did not import symbolic links correctly.
+
+ * http.c used CURLOPT_SSLKEY even on libcURL version 7.9.2, even though
+ it was only available starting 7.9.3.
+
+ * low-level filelevel merge driver used return value from strdup()
+ without checking if we ran out of memory.
+
+ * "git rebase -i" left stray closing parenthesis in its reflog message.
+
+ * "git remote show" did not show all the URLs associated with the named
+ remote, even though "git remote -v" did. Made them consistent by
+ making the former show all URLs.
+
+ * "whitespace" attribute that is set was meant to detect all errors known
+ to git, but it told git to ignore trailing carriage-returns.
+
+Includes other documentation fixes.
--- /dev/null
+GIT v1.6.3.4 Release Notes
+==========================
+
+Fixes since v1.6.3.3
+--------------------
+
+ * "git add --no-ignore-errors" did not override configured
+ add.ignore-errors configuration.
+
+ * "git apply --whitespace=fix" did not fix trailing whitespace on an
+ incomplete line.
+
+ * "git branch" opened too many commit objects unnecessarily.
+
+ * "git checkout -f $commit" with a path that is a file (or a symlink) in
+ the work tree to a commit that has a directory at the path issued an
+ unnecessary error message.
+
+ * "git diff -c/--cc" was very inefficient in coalescing the removed lines
+ shared between parents.
+
+ * "git diff -c/--cc" showed removed lines at the beginning of a file
+ incorrectly.
+
+ * "git remote show nickname" did not honor configured
+ remote.nickname.uploadpack when inspecting the branches at the remote.
+
+ * "git request-pull" when talking to the terminal for a preview
+ showed some of the output in the pager.
+
+ * "git request-pull start nickname [end]" did not honor configured
+ remote.nickname.uploadpack when it ran git-ls-remote against the remote
+ repository to learn the current tip of branches.
+
+Includes other documentation updates and minor fixes.
+
--- /dev/null
+GIT v1.6.3 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default. You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing. Please refer to:
+
+ http://git.or.cz/gitwiki/GitFaq#non-bare
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning. You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+When the user does not tell "git push" what to push, it has always
+pushed matching refs. For some people it is unexpected, and a new
+configuration variable push.default has been introduced to allow
+changing a different default behaviour. To advertise the new feature,
+a big warning is issued if this is not configured and a git push without
+arguments is attempted.
+
+
+Updates since v1.6.2
+--------------------
+
+(subsystems)
+
+* various git-svn updates.
+
+* git-gui updates, including an update to Russian translation, and a
+ fix to an infinite loop when showing an empty diff.
+
+* gitk updates, including an update to Russian translation and improved Windows
+ support.
+
+(performance)
+
+* many uses of lstat(2) in the codepath for "git checkout" have been
+ optimized out.
+
+(usability, bells and whistles)
+
+* Boolean configuration variable yes/no can be written as on/off.
+
+* rsync:/path/to/repo can be used to run git over rsync for local
+ repositories. It may not be useful in practice; meant primarily for
+ testing.
+
+* http transport learned to prompt and use password when fetching from or
+ pushing to http://user@host.xz/ URL.
+
+* (msysgit) progress output that is sent over the sideband protocol can
+ be handled appropriately in Windows console.
+
+* "--pretty=<style>" option to the log family of commands can now be
+ spelled as "--format=<style>". In addition, --format=%formatstring
+ is a short-hand for --pretty=tformat:%formatstring.
+
+* "--oneline" is a synonym for "--pretty=oneline --abbrev-commit".
+
+* "--graph" to the "git log" family can draw the commit ancestry graph
+ in colors.
+
+* If you realize that you botched the patch when you are editing hunks
+ with the 'edit' action in git-add -i/-p, you can abort the editor to
+ tell git not to apply it.
+
+* @{-1} is a new way to refer to the last branch you were on introduced in
+ 1.6.2, but the initial implementation did not teach this to a few
+ commands. Now the syntax works with "branch -m @{-1} newname".
+
+* git-archive learned --output=<file> option.
+
+* git-archive takes attributes from the tree being archived; strictly
+ speaking, this is an incompatible behaviour change, but is a good one.
+ Use --worktree-attributes option to allow it to read attributes from
+ the work tree as before (deprecated git-tar tree command always reads
+ attributes from the work tree).
+
+* git-bisect shows not just the number of remaining commits whose goodness
+ is unknown, but also shows the estimated number of remaining rounds.
+
+* You can give --date=<format> option to git-blame.
+
+* "git-branch -r" shows HEAD symref that points at a remote branch in
+ interest of each tracked remote repository.
+
+* "git-branch -v -v" is a new way to get list of names for branches and the
+ "upstream" branch for them.
+
+* git-config learned -e option to open an editor to edit the config file
+ directly.
+
+* git-clone runs post-checkout hook when run without --no-checkout.
+
+* git-difftool is now part of the officially supported command, primarily
+ maintained by David Aguilar.
+
+* git-for-each-ref learned a new "upstream" token.
+
+* git-format-patch can be told to use attachment with a new configuration,
+ format.attach.
+
+* git-format-patch can be told to produce deep or shallow message threads.
+
+* git-format-patch can be told to always add sign-off with a configuration
+ variable.
+
+* git-format-patch learned format.headers configuration to add extra
+ header fields to the output. This behaviour is similar to the existing
+ --add-header=<header> option of the command.
+
+* git-format-patch gives human readable names to the attached files, when
+ told to send patches as attachments.
+
+* git-grep learned to highlight the found substrings in color.
+
+* git-imap-send learned to work around Thunderbird's inability to easily
+ disable format=flowed with a new configuration, imap.preformattedHTML.
+
+* git-rebase can be told to rebase the series even if your branch is a
+ descendant of the commit you are rebasing onto with --force-rebase
+ option.
+
+* git-rebase can be told to report diffstat with the --stat option.
+
+* Output from git-remote command has been vastly improved.
+
+* "git remote update --prune $remote" updates from the named remote and
+ then prunes stale tracking branches.
+
+* git-send-email learned --confirm option to review the Cc: list before
+ sending the messages out.
+
+(developers)
+
+* Test scripts can be run under valgrind.
+
+* Test scripts can be run with installed git.
+
+* Makefile learned 'coverage' option to run the test suites with
+ coverage tracking enabled.
+
+* Building the manpages with docbook-xsl between 1.69.1 and 1.71.1 now
+ requires setting DOCBOOK_SUPPRESS_SP to work around a docbook-xsl bug.
+ This workaround used to be enabled by default, but causes problems
+ with newer versions of docbook-xsl. In addition, there are a few more
+ knobs you can tweak to work around issues with various versions of the
+ docbook-xsl package. See comments in Documentation/Makefile for details.
+
+* Support for building and testing a subset of git on a system without a
+ working perl has been improved.
+
+
+Fixes since v1.6.2
+------------------
+
+All of the fixes in v1.6.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.2.X series.
+
+* "git-apply" rejected a patch that swaps two files (i.e. renames A to B
+ and B to A at the same time). May need to be backported by cherry
+ picking d8c81df and then 7fac0ee).
+
+* The initial checkout did not read the attributes from the .gitattribute
+ file that is being checked out.
+
+* git-gc spent excessive amount of time to decide if an object appears
+ in a locally existing pack (if needed, backport by merging 69e020a).
--- /dev/null
+GIT v1.6.4.1 Release Notes
+==========================
+
+Fixes since v1.6.4
+------------------
+
+ * An unquoted value in the configuration file, when it contains more than
+ one whitespaces in a row, got them replaced with a single space.
+
+ * "git am" used to accept a single piece of e-mail per file (not a mbox)
+ as its input, but multiple input format support in v1.6.4 broke it.
+ Apparently many people have been depending on this feature.
+
+ * The short help text for "git filter-branch" command was a single long
+ line, wrapped by terminals, and was hard to read.
+
+ * The "recursive" strategy of "git merge" segfaulted when a merge has
+ more than one merge-bases, and merging of these merge-bases involves
+ a rename/rename or a rename/add conflict.
+
+ * "git pull --rebase" did not use the right fork point when the
+ repository has already fetched from the upstream that rewinds the
+ branch it is based on in an earlier fetch.
+
+ * Explain the concept of fast-forward more fully in "git push"
+ documentation, and hint to refer to it from an error message when the
+ command refuses an update to protect the user.
+
+ * The default value for pack.deltacachesize, used by "git repack", is now
+ 256M, instead of unbounded. Otherwise a repack of a moderately sized
+ repository would needlessly eat into swap.
+
+ * Document how "git repack" (hence "git gc") interacts with a repository
+ that borrows its objects from other repositories (e.g. ones created by
+ "git clone -s").
+
+ * "git show" on an annotated tag lacked a delimiting blank line between
+ the tag itself and the contents of the object it tags.
+
+ * "git verify-pack -v" erroneously reported number of objects with too
+ deep delta depths as "chain length 0" objects.
+
+ * Long names of authors and committers outside US-ASCII were sometimes
+ incorrectly shown in "gitweb".
+
+Other minor documentation updates are included.
--- /dev/null
+GIT v1.6.4.2 Release Notes
+==========================
+
+Fixes since v1.6.4.1
+--------------------
+
+* --date=relative output between 1 and 5 years ago rounded the number of
+ years when saying X years Y months ago, instead of rounding it down.
+
+* "git add -p" did not handle changes in executable bits correctly
+ (a regression around 1.6.3).
+
+* "git apply" did not honor GNU diff's convention to mark the creation/deletion
+ event with UNIX epoch timestamp on missing side.
+
+* "git checkout" incorrectly removed files in a directory pointed by a
+ symbolic link during a branch switch that replaces a directory with
+ a symbolic link.
+
+* "git clean -d -f" happily descended into a subdirectory that is managed by a
+ separate git repository. It now requires two -f options for safety.
+
+* "git fetch/push" over http transports had two rather grave bugs.
+
+* "git format-patch --cover-letter" did not prepare the cover letter file
+ for use with non-ASCII strings when there are the series contributors with
+ non-ASCII names.
+
+* "git pull origin branch" and "git fetch origin && git merge origin/branch"
+ left different merge messages in the resulting commit.
+
+Other minor documentation updates are included.
--- /dev/null
+GIT v1.6.4.3 Release Notes
+==========================
+
+Fixes since v1.6.4.2
+--------------------
+
+* "git clone" from an empty repository gave unnecessary error message,
+ even though it did everything else correctly.
+
+* "git cvsserver" invoked git commands via "git-foo" style, which has long
+ been deprecated.
+
+* "git fetch" and "git clone" had an extra sanity check to verify the
+ presence of the corresponding *.pack file before downloading *.idx
+ file by issuing a HEAD request. Github server however sometimes
+ gave 500 (Internal server error) response to HEAD even if a GET
+ request for *.pack file to the same URL would have succeeded, and broke
+ clone over HTTP from some of their repositories. As a workaround, this
+ verification has been removed (as it is not absolutely necessary).
+
+* "git grep" did not like relative pathname to refer outside the current
+ directory when run from a subdirectory.
+
+* an error message from "git push" was formatted in a very ugly way.
+
+* "git svn" did not quote the subversion user name correctly when
+ running its author-prog helper program.
+
+Other minor documentation updates are included.
--- /dev/null
+GIT v1.6.4.4 Release Notes
+==========================
+
+Fixes since v1.6.4.4
+--------------------
+
+* The workaround for Github server that sometimes gave 500 (Internal server
+ error) response to HEAD requests in 1.6.4.3 introduced a regression that
+ caused re-fetching projects over http to segfault in certain cases due
+ to uninitialized pointer being freed.
+
+* "git pull" on an unborn branch used to consider anything in the work
+ tree and the index discardable.
+
+* "git diff -b/w" did not work well on the incomplete line at the end of
+ the file, due to an incorrect hashing of lines in the low-level xdiff
+ routines.
+
+* "git checkout-index --prefix=$somewhere" used to work when $somewhere is
+ a symbolic link to a directory elsewhere, but v1.6.4.2 broke it.
+
+* "git unpack-objects --strict", invoked when receive.fsckobjects
+ configuration is set in the receiving repository of "git push", did not
+ properly check the objects, especially the submodule links, it received.
+
+Other minor documentation updates are included.

+
+
+Updates since v1.6.3
+--------------------
+
+(subsystems)
+
+ * gitweb Perl style clean-up.
+
+ * git-svn updates, including a new --authors-prog option to map author
+ names by invoking an external program, 'git svn reset' to unwind
+ 'git svn fetch', support for more than one branches, documenting
+ of the useful --minimize-url feature, new "git svn gc" command, etc.
+
+(portability)
+
+ * We feed iconv with "UTF-8" instead of "utf8"; the former is
+ understood more widely. Similarly updated test scripts to use
+ encoding names more widely understood (e.g. use "ISO8859-1" instead
+ of "ISO-8859-1").
+
+ * Various portability fixes/workarounds for different vintages of
+ SunOS, IRIX, and Windows.
+
+ * Git-over-ssh transport on Windows supports PuTTY plink and TortoisePlink.
+
+(performance)
+
+ * Many repeated use of lstat() are optimized out in "checkout" codepath.
+
+ * git-status (and underlying git-diff-index --cached) are optimized
+ to take advantage of cache-tree information in the index.
+
+(usability, bells and whistles)
+
+ * "git add --edit" lets users edit the whole patch text to fine-tune what
+ is added to the index.
+
+ * "git am" accepts StGIT series file as its input.
+
+ * "git bisect skip" skips to a more randomly chosen place in the hope
+ to avoid testing a commit that is too close to a commit that is
+ already known to be untestable.
+
+ * "git cvsexportcommit" learned -k option to stop CVS keywords expansion
+
+ * "git fast-export" learned to handle history simplification more
+ gracefully.
+
+ * "git fast-export" learned an option --tag-of-filtered-object to handle
+ dangling tags resulting from history simplification more usefully.
+
+ * "git grep" learned -p option to show the location of the match using the
+ same context hunk marker "git diff" uses.
+
+ * https transport can optionally be told that the used client
+ certificate is password protected, in which case it asks the
+ password only once.
+
+ * "git imap-send" is IPv6 aware.
+
+ * "git log --graph" draws graphs more compactly by using horizontal lines
+ when able.
+
+ * "git log --decorate" shows shorter refnames by stripping well-known
+ refs/* prefix.
+
+ * "git push $name" honors remote.$name.pushurl if present before
+ using remote.$name.url. In other words, the URL used for fetching
+ and pushing can be different.
+
+ * "git send-email" understands quoted aliases in .mailrc files (might
+ have to be backported to 1.6.3.X).
+
+ * "git send-email" can fetch the sender address from the configuration
+ variable "sendmail.from" (and "sendmail.<identity>.from").
+
+ * "git show-branch" can color its output.
+
+ * "add" and "update" subcommands to "git submodule" learned --reference
+ option to use local clone with references.
+
+ * "git submodule update" learned --rebase option to update checked
+ out submodules by rebasing the local changes.
+
+ * "gitweb" can optionally use gravatar to adorn author/committer names.

+ * A major part of the "git bisect" wrapper has moved to C.
+
+ * Formatting with the new version of AsciiDoc 8.4.1 is now supported.
+
+Fixes since v1.6.3
+------------------
+
+All of the fixes in v1.6.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.3.X series.
+
+ * "git diff-tree -r -t" used to omit new or removed directories from
+ the output. df533f3 (diff-tree -r -t: include added/removed
+ directories in the output, 2009-06-13) may need to be cherry-picked
+ to backport this fix.
+
+ * The way Git.pm sets up a Repository object was not friendly to callers
+ that chdir around. It now internally records the repository location
+ as an absolute path when autodetected.
+
+ * Removing a section with "git config --remove-section", when its
+ section header has a variable definition on the same line, lost
+ that variable definition.
+
+ * "git rebase -p --onto" used to always leave side branches of a merge
+ intact, even when both branches are subject to rewriting.
+
+ * "git repack" used to faithfully follow grafts and considered true
+ parents recorded in the commit object unreachable from the commit.
+ After such a repacking, you cannot remove grafts without corrupting
+ the repository.
+
+ * "git send-email" did not detect erroneous loops in alias expansion.

+GIT v1.6.5.1 Release Notes
+==========================
+
+Fixes since v1.6.5
+------------------
+
+ * An corrupt pack could make codepath to read objects into an
+ infinite loop.
+
+ * Download throughput display was always shown in KiB/s but on fast links
+ it is more appropriate to show it in MiB/s.
+
+ * "git grep -f filename" used uninitialized variable and segfaulted.
+
+ * "git clone -b branch" gave a wrong commit object name to post-checkout
+ hook.
+
+ * "git pull" over http did not work on msys.
+
+Other minor documentation updates are included.
--- /dev/null
+GIT v1.6.5.2 Release Notes
+==========================
+
+Fixes since v1.6.5.1
+--------------------
+
+ * Installation of templates triggered a bug in busybox when using tar
+ implementation from it.
+
+ * "git add -i" incorrectly ignored paths that are already in the index
+ if they matched .gitignore patterns.
+
+ * "git describe --always" should have produced some output even there
+ were no tags in the repository, but it didn't.
+
+ * "git ls-files" when showing tracked files incorrectly paid attention
+ to the exclude patterns.
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.5.3 Release Notes
+==========================
+
+Fixes since v1.6.5.2
+--------------------
+
+ * info/grafts file didn't ignore trailing CR at the end of lines.
+
+ * Packages generated on newer FC were unreadable by older versions of
+ RPM as the new default is to use stronger hash.
+
+ * output from "git blame" was unreadable when the file ended in an
+ incomplete line.
+
+ * "git add -i/-p" didn't handle deletion of empty files correctly.
+
+ * "git clone" takes up to two parameters, but did not complain when
+ given more arguments than necessary and silently ignored them.
+
+ * "git cvsimport" did not read files given as command line arguments
+ correctly when it is run from a subdirectory.
+
+ * "git diff --color-words -U0" didn't work correctly.
+
+ * The handling of blank lines at the end of file by "git diff/apply
+ --whitespace" was inconsistent with the other kinds of errors.
+ They are now colored, warned against, and fixed the same way as others.
+
+ * There was no way to allow blank lines at the end of file without
+ allowing extra blanks at the end of lines. You can use blank-at-eof
+ and blank-at-eol whitespace error class to specify them separately.
+ The old trailing-space error class is now a short-hand to set both.
+
+ * "-p" option to "git format-patch" was supposed to suppress diffstat
+ generation, but it was broken since 1.6.1.
+
+ * "git imap-send" did not compile cleanly with newer OpenSSL.
+
+ * "git help -a" outside of a git repository was broken.
+
+ * "git ls-files -i" was supposed to be inverse of "git ls-files" without -i
+ with respect to exclude patterns, but it was broken since 1.6.5.2.
+
+ * "git ls-remote" outside of a git repository over http was broken.
+
+ * "git rebase -i" gave bogus error message when the command word was
+ misspelled.
+
+ * "git receive-pack" that is run in response to "git push" did not run
+ garbage collection nor update-server-info, but in larger hosting sites,
+ these almost always need to be run. To help site administrators, the
+ command now runs "gc --auto" and "u-s-i" by setting receive.autogc
+ and receive.updateserverinfo configuration variables, respectively.
+
+ * Release notes spelled the package name with incorrect capitalization.
+
+ * "gitweb" did not escape non-ascii characters correctly in the URL.
+
+ * "gitweb" showed "patch" link even for merge commits.
+
+ * "gitweb" showed incorrect links for blob line numbers in pathinfo mode.
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.5.4 Release Notes
+==========================
+
+Fixes since v1.6.5.3
+--------------------
+
+ * "git help" (without argument) used to check if you are in a directory
+ under git control. There was no breakage in behaviour per-se, but this
+ was unnecessary.
+
+ * "git prune-packed" gave progress output even when its standard error is
+ not connected to a terminal; this caused cron jobs that run it to
+ produce crufts.
+
+ * "git pack-objects --all-progress" is an option to ask progress output
+ from write-object phase _if_ progress output were to be produced, and
+ shouldn't have forced the progress output.
+
+ * "git apply -p<n> --directory=<elsewhere>" did not work well for a
+ non-default value of n.
+
+ * "git merge foo HEAD" was misparsed as an old-style invocation of the
+ command and produced a confusing error message. As it does not specify
+ any other branch to merge, it shouldn't be mistaken as such. We will
+ remove the old style "git merge <message> HEAD <commit>..." syntax in
+ future versions, but not in this release,
+
+ * "git merge -m <message> <branch>..." added the standard merge message
+ on its own after user-supplied message, which should have overridden the
+ standard one.
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.5.5 Release Notes
+==========================
+
+Fixes since v1.6.5.4
+--------------------
+
+ * Manual pages can be formatted with older xmlto again.
+
+ * GREP_OPTIONS exported from user's environment could have broken
+ our scripted commands.
+
+ * In configuration files, a few variables that name paths can begin with
+ ~/ and ~username/ and they are expanded as expected. This is not a
+ bugfix but 1.6.6 will have this and without backporting users cannot
+ easily use the same ~/.gitconfig across versions.
+
+ * "git diff -B -M" did the same computation to hash lines of contents
+ twice, and held onto memory after it has used the data in it
+ unnecessarily before it freed.
+
+ * "git diff -B" and "git diff --dirstat" was not counting newly added
+ contents correctly.
+
+ * "git format-patch revisions... -- path" issued an incorrect error
+ message that suggested to use "--" on the command line when path
+ does not exist in the current work tree (it is a separate matter if
+ it makes sense to limit format-patch with pathspecs like that
+ without using the --full-diff option).
+
+ * "git grep -F -i StRiNg" did not work as expected.
+
+ * Enumeration of available merge strategies iterated over the list of
+ commands in a wrong way, sometimes producing an incorrect result.
+
+ * "git shortlog" did not honor the "encoding" header embedded in the
+ commit object like "git log" did.
+
+ * Reading progress messages that come from the remote side while running
+ "git pull" is given precedence over reading the actual pack data to
+ prevent garbled progress message on the user's terminal.
+
+ * "git rebase" got confused when the log message began with certain
+ strings that looked like Subject:, Date: or From: header.
+
+ * "git reset" accidentally run in .git/ directory checked out the
+ work tree contents in there.
+
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.5.6 Release Notes
+==========================
+
+Fixes since v1.6.5.5
+--------------------
+
+ * "git add -p" had a regression since v1.6.5.3 that broke deletion of
+ non-empty files.
+
+ * "git archive -o o.zip -- Makefile" produced an archive in o.zip
+ but in POSIX tar format.
+
+ * Error message given to "git pull --rebase" when the user didn't give
+ enough clue as to what branch to integrate with still talked about
+ "merging with" the branch.
+
+ * Error messages given by "git merge" when the merge resulted in a
+ fast-forward still were in plumbing lingo, even though in v1.6.5
+ we reworded messages in other cases.
+
+ * The post-upload-hook run by upload-pack in response to "git fetch" has
+ been removed, due to security concerns (the hook first appeared in
+ 1.6.5).
--- /dev/null
+Git v1.6.5.7 Release Notes
+==========================
+
+Fixes since v1.6.5.6
+--------------------
+
+* If a user specifies a color for a <slot> (i.e. a class of things to show
+ in a particular color) that is known only by newer versions of git
+ (e.g. "color.diff.func" was recently added for upcoming 1.6.6 release),
+ an older version of git should just ignore them. Instead we diagnosed
+ it as an error.
+
+* With help.autocorrect set to non-zero value, the logic to guess typos
+ in the subcommand name misfired and ran a random nonsense command.
+
+* If a command is run with an absolute path as a pathspec inside a bare
+ repository, e.g. "rev-list HEAD -- /home", the code tried to run
+ strlen() on NULL, which is the result of get_git_work_tree(), and
+ segfaulted.
--- /dev/null
+Git v1.6.5.8 Release Notes
+==========================
+
+Fixes since v1.6.5.7
+--------------------
+
+* "git count-objects" did not handle packfiles that are bigger than 4G on
+ platforms with 32-bit off_t.
+
+* "git rebase -i" did not abort cleanly if it failed to launch the editor.
+
+* "git blame" did not work well when commit lacked the author name.
+
+* "git fast-import" choked when handling a tag that points at an object
+ that is not a commit.
+
+* "git reset --hard" did not work correctly when GIT_WORK_TREE environment
+ variable is used to point at the root of the true work tree.
+
+* "git grep" fed a buffer that is not NUL-terminated to underlying
+ regexec().
+
+* "git checkout -m other" while on a branch that does not have any commit
+ segfaulted, instead of failing.
+
+* "git branch -a other" should have diagnosed the command as an error.
+
+Other minor documentation updates are also included.
--- /dev/null
+GIT v1.6.5 Release Notes
+========================
+
+In git 1.7.0, which was planned to be the release after 1.6.5, "git
+push" into a branch that is currently checked out will be refused by
+default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyCurrentBranch in the receiving
+repository.
+
+Also, "git push $there :$killed" to delete the branch $killed in a remote
+repository $there, when $killed branch is the current branch pointed at by
+its HEAD, will be refused by default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyDeleteCurrent in the receiving
+repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing. Please refer to:
+
+ http://git.or.cz/gitwiki/GitFaq#non-bare
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+Updates since v1.6.4
+--------------------
+
+(subsystems)
+
+ * various updates to gitk, git-svn and gitweb.
+
+(portability)
+
+ * more improvements on mingw port.
+
+ * mingw will also give FRSX as the default value for the LESS
+ environment variable when the user does not have one.
+
+ * initial support to compile git on Windows with MSVC.
+
+(performance)
+
+ * On major platforms, the system can be compiled to use with Linus's
+ block-sha1 implementation of the SHA-1 hash algorithm, which
+ outperforms the default fallback implementation we borrowed from
+ Mozilla.
+
+ * Unnecessary inefficiency in deepening of a shallow repository has
+ been removed.
+
+ * "git clone" does not grab objects that it does not need (i.e.
+ referenced only from refs outside refs/heads and refs/tags
+ hierarchy) anymore.
+
+ * The "git" main binary used to link with libcurl, which then dragged
+ in a large number of external libraries. When using basic plumbing
+ commands in scripts, this unnecessarily slowed things down. We now
+ implement http/https/ftp transfer as a separate executable as we
+ used to.
+
+ * "git clone" run locally hardlinks or copies the files in .git/ to
+ newly created repository. It used to give new mtime to copied files,
+ but this delayed garbage collection to trigger unnecessarily in the
+ cloned repository. We now preserve mtime for these files to avoid
+ this issue.
+
+(usability, bells and whistles)
+
+ * Human writable date format to various options, e.g. --since=yesterday,
+ master@{2000.09.17}, are taught to infer some omitted input properly.
+
+ * A few programs gave verbose "advice" messages to help uninitiated
+ people when issuing error messages. An infrastructure to allow
+ users to squelch them has been introduced, and a few such messages
+ can be silenced now.
+
+ * refs/replace/ hierarchy is designed to be usable as a replacement
+ of the "grafts" mechanism, with the added advantage that it can be
+ transferred across repositories.
+
+ * "git am" learned to optionally ignore whitespace differences.
+
+ * "git am" handles input e-mail files that has CRLF line endings sensibly.
+
+ * "git am" learned "--scissors" option to allow you to discard early part
+ of an incoming e-mail.
+
+ * "git archive -o output.zip" works without being told what format to
+ use with an explicit "--format=zip".option.
+
+ * "git checkout", "git reset" and "git stash" learned to pick and
+ choose to use selected changes you made, similar to "git add -p".
+
+ * "git clone" learned a "-b" option to pick a HEAD to check out
+ different from the remote's default branch.
+
+ * "git clone" learned --recursive option.
+
+ * "git clone" from a local repository on a different filesystem used to
+ copy individual object files without preserving the old timestamp, giving
+ them extra lifetime in the new repository until they gc'ed.
+
+ * "git commit --dry-run $args" is a new recommended way to ask "what would
+ happen if I try to commit with these arguments."
+
+ * "git commit --dry-run" and "git status" shows conflicted paths in a
+ separate section to make them easier to spot during a merge.
+
+ * "git cvsimport" now supports password-protected pserver access even
+ when the password is not taken from ~/.cvspass file.
+
+ * "git fast-export" learned --no-data option that can be useful when
+ reordering commits and trees without touching the contents of
+ blobs.
+
+ * "git fast-import" has a pair of new front-end in contrib/ area.
+
+ * "git init" learned to mkdir/chdir into a directory when given an
+ extra argument (i.e. "git init this").
+
+ * "git instaweb" optionally can use mongoose as the web server.
+
+ * "git log --decorate" can optionally be told with --decorate=full to
+ give the reference name in full.
+
+ * "git merge" issued an unnecessarily scary message when it detected
+ that the merge may have to touch the path that the user has local
+ uncommitted changes to. The message has been reworded to make it
+ clear that the command aborted, without doing any harm.
+
+ * "git push" can be told to be --quiet.
+
+ * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
+ that is derived from the URL used for fetching.
+
+ * informational output from "git reset" that lists the locally modified
+ paths is made consistent with that of "git checkout $another_branch".
+
+ * "git submodule" learned to give submodule name to scripts run with
+ "foreach" subcommand.
+
+ * various subcommands to "git submodule" learned --recursive option.
+
+ * "git submodule summary" learned --files option to compare the work
+ tree vs the commit bound at submodule path, instead of comparing
+ the index.
+
+ * "git upload-pack", which is the server side support for "git clone" and
+ "git fetch", can call a new post-upload-pack hook for statistics purposes.
+
+(developers)
+
+ * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
+ source directory; using tmpfs may give faster turnaround.
+
+ * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
+ build for one location, and install into another location to tar it
+ up.
+
+Fixes since v1.6.4
+------------------
+
+All of the fixes in v1.6.4.X maintenance series are included in this
+release, unless otherwise noted.
--- /dev/null
+Git v1.6.6.1 Release Notes
+==========================
+
+Fixes since v1.6.6
+------------------
+
+ * "git blame" did not work well when commit lacked the author name.
+
+ * "git branch -a name" wasn't diagnosed as an error.
+
+ * "git count-objects" did not handle packfiles that are bigger than 4G on
+ platforms with 32-bit off_t.
+
+ * "git checkout -m other" while on a branch that does not have any commit
+ segfaulted, instead of failing.
+
+ * "git fast-import" choked when fed a tag that do not point at a
+ commit.
+
+ * "git grep" finding from work tree files could have fed garbage to
+ the underlying regexec(3).
+
+ * "git grep -L" didn't show empty files (they should never match, and
+ they should always appear in -L output as unmatching).
+
+ * "git rebase -i" did not abort cleanly if it failed to launch the editor.
+
+ * "git reset --hard" did not work correctly when GIT_WORK_TREE environment
+ variable is used to point at the root of the true work tree.
+
+ * http-backend was not listed in the command list in the documentation.
+
+ * Building on FreeBSD (both 7 and 8) needs OLD_ICONV set in the Makefile
+
+ * "git checkout -m some-branch" while on an unborn branch crashed.
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.6.2 Release Notes
+==========================
+
+Fixes since v1.6.6.1
+--------------------
+
+ * recursive merge didn't correctly diagnose its own programming errors,
+ and instead caused the caller to segfault.
+
+ * The new "smart http" aware clients probed the web servers to see if
+ they support smart http, but did not fall back to dumb http transport
+ correctly with some servers.
+
+ * Time based reflog syntax e.g. "@{yesterday}" didn't diagnose a misspelled
+ time specification and instead assumed "@{now}".
+
+ * "git archive HEAD -- no-such-directory" produced an empty archive
+ without complaining.
+
+ * "git blame -L start,end -- file" misbehaved when given a start that is
+ larger than the number of lines in the file.
+
+ * "git checkout -m" didn't correctly call custom merge backend supplied
+ by the end user.
+
+ * "git config -f <file>" misbehaved when run from a subdirectory.
+
+ * "git cvsserver" didn't like having regex metacharacters (e.g. '+') in
+ CVSROOT environment.
+
+ * "git fast-import" did not correctly handle large blobs that may
+ bust the pack size limit.
+
+ * "git gui" is supposed to work even when launched from inside a .git
+ directory.
+
+ * "git gui" misbehaved when applying a hunk that ends with deletion.
+
+ * "git imap-send" did not honor imap.preformattedHTML as documented.
+
+ * "git log" family incorrectly showed the commit notes unconditionally by
+ mistake, which was especially irritating when running "git log --oneline".
+
+ * "git status" shouldn't require an write access to the repository.
+
+Other minor documentation updates are included.
--- /dev/null
+Git v1.6.6 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * In this release, "git fsck" defaults to "git fsck --full" and
+ checks packfiles, and because of this it will take much longer to
+ complete than before. If you prefer a quicker check only on loose
+ objects (the old default), you can say "git fsck --no-full". This
+ has been supported by 1.5.4 and newer versions of git, so it is
+ safe to write it in your script even if you use slightly older git
+ on some of your machines.
+
+Preparing yourselves for compatibility issues in 1.7.0
+------------------------------------------------------
+
+In git 1.7.0, which is planned to be the release after 1.6.6, there will
+be a handful of behaviour changes that will break backward compatibility.
+
+These changes were discussed long time ago and existing behaviours have
+been identified as more problematic to the userbase than keeping them for
+the sake of backward compatibility.
+
+When necessary, a transition strategy for existing users has been designed
+not to force them running around setting configuration variables and
+updating their scripts in order to either keep the traditional behaviour
+or adjust to the new behaviour, on the day their sysadmin decides to install
+the new version of git. When we switched from "git-foo" to "git foo" in
+1.6.0, even though the change had been advertised and the transition
+guide had been provided for a very long time, the users procrastinated
+during the entire transition period, and ended up panicking on the day
+their sysadmins updated their git installation. We are trying to avoid
+repeating that unpleasantness in the 1.7.0 release.
+
+For changes decided to be in 1.7.0, commands that will be affected
+have been much louder to strongly discourage such procrastination, and
+they continue to be in this release. If you have been using recent
+versions of git, you would have seen warnings issued when you used
+features whose behaviour will change, with a clear instruction on how
+to keep the existing behaviour if you want to. You hopefully are
+already well prepared.
+
+Of course, we have also been giving "this and that will change in
+1.7.0; prepare yourselves" warnings in the release notes and
+announcement messages for the past few releases. Let's see how well
+users will fare this time.
+
+ * "git push" into a branch that is currently checked out (i.e. pointed by
+ HEAD in a repository that is not bare) will be refused by default.
+
+ Similarly, "git push $there :$killed" to delete the branch $killed
+ in a remote repository $there, when $killed branch is the current
+ branch pointed at by its HEAD, will be refused by default.
+
+ Setting the configuration variables receive.denyCurrentBranch and
+ receive.denyDeleteCurrent to 'ignore' in the receiving repository
+ can be used to override these safety features. Versions of git
+ since 1.6.2 have issued a loud warning when you tried to do these
+ operations without setting the configuration, so repositories of
+ people who still need to be able to perform such a push should
+ already have been future proofed.
+
+ Please refer to:
+
+ http://git.or.cz/gitwiki/GitFaq#non-bare
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+ for more details on the reason why this change is needed and the
+ transition process that already took place so far.
+
+ * "git send-email" will not make deep threads by default when sending a
+ patch series with more than two messages. All messages will be sent
+ as a reply to the first message, i.e. cover letter. Git 1.6.6 (this
+ release) will issue a warning about the upcoming default change, when
+ it uses the traditional "deep threading" behaviour as the built-in
+ default. To squelch the warning but still use the "deep threading"
+ behaviour, give --chain-reply-to option or set sendemail.chainreplyto
+ to true.
+
+ It has been possible to configure send-email to send "shallow thread"
+ by setting sendemail.chainreplyto configuration variable to false.
+ The only thing 1.7.0 release will do is to change the default when
+ you haven't configured that variable.
+
+ * "git status" will not be "git commit --dry-run". This change does not
+ affect you if you run the command without pathspec.
+
+ Nobody sane found the current behaviour of "git status Makefile" useful
+ nor meaningful, and it confused users. "git commit --dry-run" has been
+ provided as a way to get the current behaviour of this command since
+ 1.6.5.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+ only as a way to filter the patch output. "git diff --exit-code -b"
+ exited with non-zero status even if all changes were about changing the
+ amount of whitespace and nothing else. and "git diff -b" showed the
+ "diff --git" header line for such a change without patch text.
+
+ In 1.7.0, the "ignore whitespaces" will affect the semantics of the
+ diff operation itself. A change that does not affect anything but
+ whitespaces will be reported with zero exit status when run with
+ --exit-code, and there will not be "diff --git" header for such a
+ change.
+
+
+Updates since v1.6.5
+--------------------
+
+(subsystems)
+
+ * various gitk updates including use of themed widgets under Tk 8.5,
+ Japanese translation, a fix to a bug when running "gui blame" from
+ a subdirectory, etc.
+
+ * various git-gui updates including new translations, wm states fixes,
+ Tk bug workaround after quitting, improved heuristics to trigger gc,
+ etc.
+
+ * various git-svn updates.
+
+ * "git fetch" over http learned a new mode that is different from the
+ traditional "dumb commit walker".
+
+(portability)
+
+ * imap-send can be built on mingw port.
+
+(performance)
+
+ * "git diff -B" has smaller memory footprint.
+
+(usability, bells and whistles)
+
+ * The object replace mechanism can be bypassed with --no-replace-objects
+ global option given to the "git" program.
+
+ * In configuration files, a few variables that name paths can begin with ~/
+ and ~username/ and they are expanded as expected.
+
+ * "git subcmd -h" now shows short usage help for many more subcommands.
+
+ * "git bisect reset" can reset to an arbitrary commit.
+
+ * "git checkout frotz" when there is no local branch "frotz" but there
+ is only one remote tracking branch "frotz" is taken as a request to
+ start the named branch at the corresponding remote tracking branch.
+
+ * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
+ to ignore authorship information in the commit it is taking the message
+ from.
+
+ * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
+
+ * "git diff" learned --submodule option to show a list of one-line logs
+ instead of differences between the commit object names.
+
+ * "git diff" learned to honor diff.color.func configuration to paint
+ function name hint printed on the hunk header "@@ -j,k +l,m @@" line
+ in the specified color.
+
+ * "git fetch" learned --all and --multiple options, to run fetch from
+ many repositories, and --prune option to remove remote tracking
+ branches that went stale. These make "git remote update" and "git
+ remote prune" less necessary (there is no plan to remove "remote
+ update" nor "remote prune", though).
+
+ * "git fsck" by default checks the packfiles (i.e. "--full" is the
+ default); you can turn it off with "git fsck --no-full".
+
+ * "git grep" can use -F (fixed strings) and -i (ignore case) together.
+
+ * import-tars contributed fast-import frontend learned more types of
+ compressed tarballs.
+
+ * "git instaweb" knows how to talk with mod_cgid to apache2.
+
+ * "git log --decorate" shows the location of HEAD as well.
+
+ * "git log" and "git rev-list" learned to take revs and pathspecs from
+ the standard input with the new "--stdin" option.
+
+ * "--pretty=format" option to "log" family of commands learned:
+
+ . to wrap text with the "%w()" specifier.
+ . to show reflog information with "%g[sdD]" specifier.
+
+ * "git notes" command to annotate existing commits.
+
+ * "git merge" (and "git pull") learned --ff-only option to make it fail
+ if the merge does not result in a fast-forward.
+
+ * "git mergetool" learned to use p4merge.
+
+ * "git rebase -i" learned "reword" that acts like "edit" but immediately
+ starts an editor to tweak the log message without returning control to
+ the shell, which is done by "edit" to give an opportunity to tweak the
+ contents.
+
+ * "git send-email" can be told with "--envelope-sender=auto" to use the
+ same address as "From:" address as the envelope sender address.
+
+ * "git send-email" will issue a warning when it defaults to the
+ --chain-reply-to behaviour without being told by the user and
+ instructs to prepare for the change of the default in 1.7.0 release.
+
+ * In "git submodule add <repository> <path>", <path> is now optional and
+ inferred from <repository> the same way "git clone <repository>" does.
+
+ * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
+
+ * "git svn" learned to recreate empty directories tracked only by SVN.
+
+ * "gitweb" can optionally render its "blame" output incrementally (this
+ requires JavaScript on the client side).
+
+ * Author names shown in gitweb output are links to search commits by the
+ author.

+Fixes since v1.6.5
+------------------
+
+All of the fixes in v1.6.5.X maintenance series are included in this
+release, unless otherwise noted.
--- /dev/null
+Git v1.7.0.1 Release Notes
+==========================
+
+Fixes since v1.7.0
+------------------
+
+ * In a freshly created repository "rev-parse HEAD^0" complained that
+ it is dangling symref, even though "rev-parse HEAD" didn't.
+
+ * "git show :no-such-name" tried to access the index without bounds
+ check, leading to a potential segfault.
+
+ * Message from "git cherry-pick" was harder to read and use than necessary
+ when it stopped due to conflicting changes.
+
+ * We referred to ".git/refs/" throughout the documentation when we
+ meant to talk about abstract notion of "ref namespace". Because
+ people's repositories often have packed refs these days, this was
+ confusing.
+
+ * "git diff --output=/path/that/cannot/be/written" did not correctly
+ error out.
+
+ * "git grep -e -pattern-that-begin-with-dash paths..." could not be
+ spelled as "git grep -- -pattern-that-begin-with-dash paths..." which
+ would be a GNU way to use "--" as "end of options".
+
+ * "git grep" compiled with threading support tried to access an
+ uninitialized mutex on boxes with a single CPU.
+
+ * "git stash pop -q --index" failed because the unnecessary --index
+ option was propagated to "git stash drop" that is internally run at the
+ end.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.2 Release Notes
+==========================
+
+Fixes since v1.7.0.1
+--------------------
+
+ * GIT_PAGER was not honored consistently by some scripted Porcelains, most
+ notably "git am".
+
+ * updating working tree files after telling git to add them to the
+ index and while it is still working created garbage object files in
+ the repository without diagnosing it as an error.
+
+ * "git bisect -- pathspec..." did not diagnose an error condition properly when
+ the simplification with given pathspec made the history empty.
+
+ * "git rev-list --cherry-pick A...B" now has an obvious optimization when the
+ histories haven't diverged (i.e. when one end is an ancestor of the other).
+
+ * "git diff --quiet -w" did not work as expected.
+
+ * "git fast-import" didn't work with a large input, as it lacked support
+ for producing the pack index in v2 format.
+
+ * "git imap-send" didn't use CRLF line endings over the imap protocol
+ when storing its payload to the draft box, violating RFC 3501.
+
+ * "git log --format='%w(x,y,z)%b'" and friends that rewrap message
+ has been optimized for utf-8 payload.
+
+ * Error messages generated on the receiving end did not come back to "git
+ push".
+
+ * "git status" in 1.7.0 lacked the optimization we used to have in 1.6.X series
+ to speed up scanning of large working tree.
+
+ * "gitweb" did not diagnose parsing errors properly while reading tis configuration
+ file.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.3 Release Notes
+==========================
+
+Fixes since v1.7.0.2
+--------------------
+
+ * Object files are created in a more ACL friendly way in repositories
+ where group permission is ACL controlled.
+
+ * "git add -i" didn't handle a deleted path very well.
+
+ * "git blame" padded line numbers with one extra SP when the total number
+ of lines was one less than multiple of ten due to an off-by-one error.
+
+ * "git fetch --all/--multi" used to discard information for remotes that
+ are fetched earlier.
+
+ * "git log --author=me --grep=it" tried to find commits that have "it"
+ or are written by "me", instead of the ones that have "it" _and_ are
+ written by "me".
+
+ * "git log -g branch" misbehaved when there was no entries in the reflog
+ for the named branch.
+
+ * "git mailinfo" (hence "git am") incorrectly removed initial indent from
+ paragraphs.
+
+ * "git prune" and "git reflog" (hence "git gc" as well) didn't honor
+ an instruction never to expire by setting gc.reflogexpire to never.
+
+ * "git push" misbehaved when branch.<name>.merge was configured without
+ matching branch.<name>.remote.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.4 Release Notes
+==========================
+
+Fixes since v1.7.0.3
+--------------------
+
+ * Optimized ntohl/htonl on big-endian machines were broken.
+
+ * Color values given to "color.<cmd>.<slot>" configuration can now have
+ more than one attributes (e.g. "bold ul").
+
+ * "git add -u nonexistent-path" did not complain.
+
+ * "git apply --whitespace=fix" didn't work well when an early patch in
+ a patch series adds trailing blank lines and a later one depended on
+ such a block of blank lines at the end.
+
+ * "git fast-export" didn't check error status and stop when marks file
+ cannot be opened.
+
+ * "git format-patch --ignore-if-in-upstream" gave unwarranted errors
+ when the range was empty, instead of silently finishing.
+
+ * "git remote prune" did not detect remote tracking refs that became
+ dangling correctly.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.5 Release Notes
+==========================
+
+Fixes since v1.7.0.4
+--------------------
+
+ * "git daemon" failed to compile on platforms without sockaddr_storage type.
+
+ * Output from "git rev-list --pretty=oneline" was unparsable when a
+ commit did not have any message, which is abnormal but possible in a
+ repository converted from foreign scm.
+
+ * "git stash show <commit-that-is-not-a-stash>" gave an error message
+ that was not so useful. Reworded the message to "<it> is not a
+ stash".
+
+ * Python scripts in contrib/ area now start with "#!/usr/bin/env python"
+ to honor user's PATH.
+
+ * "git imap-send" used to mistake any line that begins with "From " as a
+ message separator in format-patch output.
+
+ * Smart http server backend failed to report an internal server error and
+ infinitely looped instead after output pipe was closed.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.6 Release Notes
+==========================
+
+Fixes since v1.7.0.5
+--------------------
+
+ * "git diff --stat" used "int" to count the size of differences,
+ which could result in overflowing.
+
+ * "git rev-list --abbrev-commit" defaulted to 40-byte abbreviations, unlike
+ newer tools in the git toolset.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0.7 Release Notes
+==========================
+
+Fixes since v1.7.0.6
+--------------------
+
+ * "make NO_CURL=NoThanks install" was broken.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds
+ access to an array on the stack.
+
+ * "git config --path conf.var" to attempt to expand a variable conf.var
+ that uses "~/" short-hand segfaulted when $HOME environment variable
+ was not set.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.0 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * "git push" into a branch that is currently checked out (i.e. pointed at by
+ HEAD in a repository that is not bare) is refused by default.
+
+ Similarly, "git push $there :$killed" to delete the branch $killed
+ in a remote repository $there, when $killed branch is the current
+ branch pointed at by its HEAD, will be refused by default.
+
+ Setting the configuration variables receive.denyCurrentBranch and
+ receive.denyDeleteCurrent to 'ignore' in the receiving repository
+ can be used to override these safety features.
+
+ * "git send-email" does not make deep threads by default when sending a
+ patch series with more than two messages. All messages will be sent
+ as a reply to the first message, i.e. cover letter.
+
+ It has been possible already to configure send-email to send "shallow thread"
+ by setting sendemail.chainreplyto configuration variable to false. The
+ only thing this release does is to change the default when you haven't
+ configured that variable.
+
+ * "git status" is not "git commit --dry-run" anymore. This change does
+ not affect you if you run the command without argument.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+ only as a way to filter the patch output. "git diff --exit-code -b"
+ exited with non-zero status even if all changes were about changing the
+ amount of whitespace and nothing else; and "git diff -b" showed the
+ "diff --git" header line for such a change without patch text.
+
+ In this release, the "ignore whitespaces" options affect the semantics
+ of the diff operation. A change that does not affect anything but
+ whitespaces is reported with zero exit status when run with
+ --exit-code, and there is no "diff --git" header for such a change.
+
+ * External diff and textconv helpers are now executed using the shell.
+ This makes them consistent with other programs executed by git, and
+ allows you to pass command-line parameters to the helpers. Any helper
+ paths containing spaces or other metacharacters now need to be
+ shell-quoted. The affected helpers are GIT_EXTERNAL_DIFF in the
+ environment, and diff.*.command and diff.*.textconv in the config
+ file.
+
+ * The --max-pack-size argument to 'git repack', 'git pack-objects', and
+ 'git fast-import' was assuming the provided size to be expressed in MiB,
+ unlike the corresponding config variable and other similar options accepting
+ a size value. It is now expecting a size expressed in bytes, with a possible
+ unit suffix of 'k', 'm', or 'g'.
+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the
+ mismatch between fast-import and the frontends that produce the input
+ stream.
+
+ * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
+
+ * "gitk" and "git gui" translation updates.
+
+ * "gitweb" updates (code clean-up, load checking etc.)
+
+(portability)
+
+ * Some more MSVC portability patches for msysgit port.
+
+ * Minimum Pthreads emulation for msysgit port.
+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+ and GIT_EDITOR) can be specified with command line arguments. E.g. it
+ is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+ checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+ (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+ to another version of superproject that no longer has it did not remove
+ the submodule directory when it should (namely, when you are not
+ interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+ the conflict markers from the default 7; this is useful when tracked
+ contents (e.g. git-merge documentation) have strings that resemble the
+ conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+ substitute the name of the "upstream" of the branch. Missing branch
+ defaults to the current branch, so "git fetch && git merge @{upstream}"
+ will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+ i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+ A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+ conflicted state works even when you already ran "git add path" and
+ resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+ just like "git commit --author='<name> <email>'" can be used to
+ override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+ and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+ whose default value almost always is not (and fundamentally cannot be)
+ what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+ with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore. It can use more than
+ one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+ flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends. E.g.
+
+ - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+ strategy how much to shift the trees explicitly.
+
+ - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+ while discarding your own changes and taking merged version in
+ conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+ for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+ lets you configure your "forker" branch to later pull from "forkee"
+ branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+ merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+ but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+ together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+ for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand. Together with "git
+ checkout -m path" it will be useful when you recorded a wrong
+ resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+ conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+ to countermand it from the command line; --no-rerere-autoupdate option
+ given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more. If you build with threads, delta
+ compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+ the branch is fully merged to its upstream branch if it is not merged
+ to the current branch. It now deletes it in such a case.
+
+ * "filter-branch" command incorrectly said --prune-empty and --filter-commit
+ were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+ with something, they used to consider that a checked-out submodule with
+ uncommitted changes is not modified; this could cause people to forget
+ committing these changes in the submodule before committing in the
+ superproject. They now consider such a change as a modification and
+ "git diff" will append a "-dirty" to the work tree side when generating
+ patch output or when used with the --submodule option.
--- /dev/null
+Git v1.7.1.1 Release Notes
+==========================
+
+Fixes since v1.7.1
+------------------
+
+ * Authentication over http transport can now be made lazily, in that the
+ request can first go to a URL without username, get a 401 response and
+ then the client will ask for the username to use.
+
+ * We used to mistakenly think "../work" is a subdirectory of the current
+ directory when we are in "../work-xyz".
+
+ * The attribute mechanism now allows an entry that uses an attribute
+ macro that set/unset one attribute, immediately followed by an
+ overriding setting; this makes attribute macros much easier to use.
+
+ * We didn't recognize timezone "Z" as a synonym for "UTC" (75b37e70).
+
+ * In 1.7.0, read-tree and user commands that use the mechanism such as
+ checkout and merge were fixed to handle switching between branches one
+ of which has a file while the other has a directory at the same path
+ correctly even when there are some "confusing" pathnames in them. But
+ the algorithm used for this fix was suboptimal and had a terrible
+ performance degradation especially in larger trees.
+
+ * "git am -3" did not show diagnosis when the patch in the message was corrupt.
+
+ * After "git apply --whitespace=fix" removed trailing blank lines in an
+ patch in a patch series, it failed to apply later patches that depend
+ on the presence of such blank lines.
+
+ * "git bundle --stdin" segfaulted.
+
+ * "git checkout" and "git rebase" overwrote paths that are marked "assume
+ unchanged".
+
+ * "git commit --amend" on a commit with an invalid author-name line that
+ lacks the display name didn't work.
+
+ * "git describe" did not tie-break tags that point at the same commit
+ correctly; newer ones are preferred by paying attention to the
+ tagger date now.
+
+ * "git diff" used to tell underlying xdiff machinery to work very hard to
+ minimize the output, but this often was spending too many extra cycles
+ for very little gain.
+
+ * "git diff --color" did not paint extended diff headers per line
+ (i.e. the coloring escape sequence didn't end at the end of line),
+ which confused "less -R".
+
+ * "git fetch" over HTTP verifies the downloaded packfiles more robustly.
+
+ * The memory usage by "git index-pack" (run during "git fetch" and "git
+ push") got leaner.
+
+ * "GIT_DIR=foo.git git init --bare bar.git" created foo.git instead of bar.git.
+
+ * "git log --abbrev=$num --format='%h' ignored --abbrev=$num.
+
+ * "git ls-files ../out/side/cwd" refused to work.
+
+ * "git merge --log" used to replace the custom message given by "-m" with
+ the shortlog, instead of appending to it.
+
+ * "git notes copy" without any other argument segfaulted.
+
+ * "git pull" accepted "--dry-run", gave it to underlying "git fetch" but
+ ignored the option itself, resulting in a bogus attempt to merge
+ unrelated commit.
+
+ * "git rebase" did not faithfully reproduce a malformed author ident, that
+ is often seen in a repository converted from foreign SCMs.
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+ a nonstandard location is in use got confused.
+
+ * "git send-email" lacked a way to specify the domainname used in the
+ EHLO/HELO exchange, causing rejected connection from picky servers.
+ It learned --smtp-domain option to solve this issue.
+
+ * "git send-email" did not declare a content-transfer-encoding and
+ content-type even when its payload needs to be sent in 8-bit.
+
+ * "git show -C -C" and other corner cases lost diff metainfo output
+ in 1.7.0.
+
+ * "git stash" incorrectly lost paths in the working tree that were
+ previously removed from the index.
+
+ * "git status" stopped refreshing the index by mistake in 1.7.1.
+
+ * "git status" showed excess "hints" even when advice.statusHints is set to false.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.1.2 Release Notes
+==========================
+
+Fixes since v1.7.1.1
+--------------------
+
+ * "git commit" did not honor GIT_REFLOG_ACTION environment variable, resulting
+ reflog messages for cherry-pick and revert actions to be recorded as "commit".
+
+ * "git clone/fetch/pull" issued an incorrect error message when a ref and
+ a symref that points to the ref were updated at the same time. This
+ obviously would update them to the same value, and should not result in
+ an error condition.
+
+ * "git diff" inside a tree with many pathnames that have certain
+ characters has become very slow in 1.7.0 by mistake.
+
+ * "git rev-parse --parseopt --stop-at-non-option" did not stop at non option
+ when --keep-dashdash was in effect.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds
+ access to an array on the stack.
+
+ * "git config --path conf.var" to attempt to expand a variable conf.var
+ that uses "~/" short-hand segfaulted when $HOME environment variable
+ was not set.
+
+And other minor fixes and documentation updates.
--- /dev/null
+Git v1.7.1 Release Notes
+========================
+
+Updates since v1.7.0
+--------------------
+
+ * Eric Raymond is the maintainer of updated CIAbot scripts, in contrib/.
+
+ * gitk updates.
+
+ * Some commands (e.g. svn and http interfaces) that interactively ask
+ for a password can be told to use an external program given via
+ GIT_ASKPASS.
+
+ * Conflict markers that lead the common ancestor in diff3-style output
+ now have a label, which hopefully would help third-party tools that
+ expect one.
+
+ * Comes with an updated bash-completion script.
+
+ * "git am" learned "--keep-cr" option to handle inputs that are
+ a mixture of changes to files with and without CRLF line endings.
+
+ * "git cvsimport" learned -R option to leave revision mapping between
+ CVS revisions and resulting git commits.
+
+ * "git diff --submodule" notices and describes dirty submodules.
+
+ * "git for-each-ref" learned %(symref), %(symref:short) and %(flag)
+ tokens.
+
+ * "git hash-object --stdin-paths" can take "--no-filters" option now.
+
+ * "git init" can be told to look at init.templatedir configuration
+ variable (obviously that has to come from either /etc/gitconfig or
+ $HOME/.gitconfig).
+
+ * "git grep" learned "--no-index" option, to search inside contents that
+ are not managed by git.
+
+ * "git grep" learned --color=auto/always/never.
+
+ * "git grep" learned to paint filename and line-number in colors.
+
+ * "git log -p --first-parent -m" shows one-parent diff for merge
+ commits, instead of showing combined diff.
+
+ * "git merge-file" learned to use custom conflict marker size and also
+ to use the "union merge" behaviour.
+
+ * "git notes" command has been rewritten in C and learned many commands
+ and features to help you carry notes forward across rebases and amends.
+
+ * "git request-pull" identifies the commit the request is relative to in
+ a more readable way.
+
+ * "git reset" learned "--keep" option that lets you discard commits
+ near the tip while preserving your local changes in a way similar
+ to how "git checkout branch" does.
+
+ * "git status" notices and describes dirty submodules.
+
+ * "git svn" should work better when interacting with repositories
+ with CRLF line endings.
+
+ * "git imap-send" learned to support CRAM-MD5 authentication.
+
+ * "gitweb" installation procedure can use "minified" js/css files
+ better.
+
+ * Various documentation updates.
+
+Fixes since v1.7.0
+------------------
+
+All of the fixes in v1.7.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git add frotz/nitfol" did not complain when the entire frotz/ directory
+ was ignored.
+
+ * "git diff --stat" used "int" to count the size of differences,
+ which could result in overflowing.
+
+ * "git rev-list --pretty=oneline" didn't terminate a record with LF for
+ commits without any message.
+
+ * "git rev-list --abbrev-commit" defaulted to 40-byte abbreviations, unlike
+ newer tools in the git toolset.
--- /dev/null
+Git v1.7.2.1 Release Notes
+==========================
+
+Fixes since v1.7.2
+------------------
+
+ * "git instaweb" wasn't useful when your Apache was installed under a
+ name other than apache2 (e.g. "httpd").
+
+ * Similarly, "git web--browse" (invoked by "git help -w") learned that

+==========================
+
+Fixes since v1.7.2.1
+--------------------
+
+ * Object transfer over smart http transport deadlocked the client when
+ the remote HTTP server returned a failure, instead of erroring it out.
+
+ * git-gui honors custom textconv filters when showing diff and blame;
+
+ * git diff --relative=subdir (without the necessary trailing /) did not
+ work well;
+
+ * "git diff-files -p --submodule" was recently broken;
+
+ * "git checkout -b n ':/token'" did not work;
+
+ * "git index-pack" (hence "git fetch/clone/pull/push") enabled the object
+ replacement machinery by mistake (it never should have);

+And other minor fixes and documentation updates.

+Git v1.7.2.3 Release Notes
+==========================
+
+Fixes since v1.7.2.2
+--------------------
+
+ * When people try insane things such as delta-compressing 4GiB files, we
+ threw an assertion failure.
+
+ * "git archive" gave the full commit ID for "$Format:%h$".
+
+ * "git fetch --tags" did not fetch tags when remote.<nick>.tagopt was set
+ to --no-tags. The command line option now overrides the configuration
+ setting.
+
+ * "git for-each-ref --format='%(objectname:short)'" has been completely
+ broken for a long time.
+
+ * "git gc" incorrectly pruned a rerere record that was created long
+ time ago but still is actively and repeatedly used.
+
+ * "git log --follow -M -p" was seriously broken in 1.7.2, reporting
+ assertion failure.
+
+ * Running "git log" with an incorrect option started pager nevertheless,
+ forcing the user to dismiss it.
+
+ * "git rebase" did not work well when the user has diff.renames
+ configuration variable set.
+
+ * An earlier (and rather old) fix to "git rebase" against a rebased
+ upstream broke a more normal, non rebased upstream case rather badly,
+ attempting to re-apply patches that are already accepted upstream.
+
+ * "git submodule sync" forgot to update the superproject's config file
+ when submodule URL changed.
+
+ * "git pack-refs --all --prune" did not remove a directory that has
+ become empty.
--- /dev/null
+Git v1.7.2 Release Notes
+========================
+
+Updates since v1.7.1
+--------------------
+
+ * core.eol configuration and text/eol attributes are the new way to control
+ the end of line conventions for files in the working tree.
+
+ * core.autocrlf has been made safer - it will now only handle line
+ endings for new files and files that are LF-only in the
+ repository. To normalize content that has been checked in with
+ CRLF, use the new eol/text attributes.
+
+ * The whitespace rules used in "git apply --whitespace" and "git diff"
+ gained a new member in the family (tab-in-indent) to help projects with
+ policy to indent only with spaces.
+
+ * When working from a subdirectory, by default, git does not look for its
+ metadirectory ".git" across filesystems, primarily to help people who
+ have invocations of git in their custom PS1 prompts, as being outside
+ of a git repository would look for ".git" all the way up to the root
+ directory, and NFS mounts are often slow. DISCOVERY_ACROSS_FILESYSTEM
+ environment variable can be used to tell git not to stop at a
+ filesystem boundary.
+
+ * Usage help messages generated by parse-options library (i.e. most
+ of the Porcelain commands) are sent to the standard output now.
+
+ * ':/<string>' notation to look for a commit now takes regular expression
+ and it is not anchored at the beginning of the commit log message
+ anymore (this is a backward incompatible change).
+
+ * "git" wrapper learned "-c name=value" option to override configuration
+ variable from the command line.
+
+ * Improved portability for various platforms including older SunOS,
+ HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
+
+ * The message from "git am -3" has been improved when conflict
+ resolution ended up making the patch a no-op.
+
+ * "git blame" applies the textconv filter to the contents it works
+ on, when available.
+
+ * "git checkout --orphan newbranch" is similar to "-b newbranch" but
+ prepares to create a root commit that is not connected to any existing
+ commit.
+
+ * "git cherry-pick" learned to pick a range of commits
+ (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
+ revert"; these do not support the nicer sequencing control "rebase
+ [-i]" has, though.
+
+ * "git cherry-pick" and "git revert" learned --strategy option to specify
+ the merge strategy to be used when performing three-way merges.
+
+ * "git cvsserver" can be told to use pserver; its password file can be
+ stored outside the repository.
+
+ * The output from the textconv filter used by "git diff" can be cached to
+ speed up their reuse.
+
+ * "git diff --word-diff=<mode>" extends the existing "--color-words"
+ option, making it more useful in color-challenged environments.
+
+ * The regexp to detect function headers used by "git diff" for PHP has
+ been enhanced for visibility modifiers (public, protected, etc.) to
+ better support PHP5.
+
+ * "diff.noprefix" configuration variable can be used to implicitly
+ ask for "diff --no-prefix" behaviour.
+
+ * "git for-each-ref" learned "%(objectname:short)" that gives the object
+ name abbreviated.
+
+ * "git format-patch" learned --signature option and format.signature
+ configuration variable to customize the e-mail signature used in the
+ output.
+
+ * Various options to "git grep" (e.g. --count, --name-only) work better
+ with binary files.
+
+ * "git grep" learned "-Ovi" to open the files with hits in your editor.
+
+ * "git help -w" learned "chrome" and "chromium" browsers.
+
+ * "git log --decorate" shows commit decorations in various colours.
+
+ * "git log --follow <path>" follows across copies (it used to only follow
+ renames). This may make the processing more expensive.
+
+ * "git log --pretty=format:<template>" specifier learned "% <something>"
+ magic that inserts a space only when %<something> expands to a
+ non-empty string; this is similar to "%+<something>" magic, but is
+ useful in a context to generate a single line output.
+
+ * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
+ what "git prune" has.
+
+ * "git patch-id" can be fed a mbox without getting confused by the
+ signature line in the format-patch output.
+
+ * "git remote" learned "set-branches" subcommand.
+
+ * "git rev-list A..B" learned --ancestry-path option to further limit
+ the result to the commits that are on the ancestry chain between A and
+ B (i.e. commits that are not descendants of A are excluded).
+
+ * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
+ to the update to make "git show master..next" walk the history,
+ introduced in 1.6.4.
+
+ * "git status [-s] --ignored" can be used to list ignored paths.
+
+ * "git status -s -b" shows the current branch in the output.
+
+ * "git status" learned "--ignore-submodules" option.
+
+ * Various "gitweb" enhancements and clean-ups, including syntax
+ highlighting, "plackup" support for instaweb, .fcgi suffix to run
+ it as FastCGI script, etc.
+
+ * The test harness has been updated to produce TAP-friendly output.
+
+ * Many documentation improvement patches are also included.
+
+
+Fixes since v1.7.1
+------------------
+
+All of the fixes in v1.7.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
+ had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
+
+ * "git clone" did not configure remote.origin.url correctly for bare
+ clones (df61c889).
+
+ * "git diff --graph" works better with "--color-words" and other options
+ (81fa024..4297c0a).
+
+ * "git diff" could show ambiguous abbreviation of blob object names on
+ its "index" line (3e5a188).
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+ a nonstandard location is in use got confused (560fb6a1).
+
+ * "git read-tree -m A B" used to switch to branch B while retaining
+ local changes added an incorrect cache-tree information (b1f47514).

+Git v1.7.3.1 Release Notes
+==========================
+
+Fixes since v1.7.3
+------------------
+
+ * "git stash show stash@{$n}" was accidentally broken in 1.7.3 ("git
+ stash show" without any argument still worked, though).
+
+ * "git stash branch $branch stash@{$n}" was accidentally broken in
+ 1.7.3 and started dropping the named stash even when branch creation

--- /dev/null
+Git v1.7.3 Release Notes
+========================
+
+Updates since v1.7.2
+--------------------
+
+ * git-gui, now at version 0.13.0, got various updates and a new
+ maintainer, Pat Thoyts.
+
+ * Gitweb allows its configuration to change per each request; it used to
+ read the configuration once upon startup.
+
+ * When git finds a corrupt object, it now reports the file that contains
+ it.
+
+ * "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
+ followed by "git checkout <it>".
+
+ * When "git checkout" or "git merge" refuse to proceed in order to
+ protect local modification to your working tree, they used to stop
+ after showing just one path that might be lost. They now show all,
+ in a format that is easier to read.
+
+ * "git clean" learned "-e" ("--exclude") option.
+
+ * Hunk headers produced for C# files by "git diff" and friends show more
+ relevant context than before.
+
+ * diff.ignoresubmodules configuration variable can be used to squelch the
+ differences in submodules reported when running commands (e.g. "diff",
+ "status", etc.) at the superproject level.
+
+ * http.useragent configuration can be used to lie who you are to your
+ restrictive firewall.
+
+ * "git rebase --strategy <s>" learned "-X" option to pass extra options
+ that are understood by the chosen merge strategy.
+
+ * "git rebase -i" learned "exec" that you can insert into the insn sheet
+ to run a command between its steps.
+
+ * "git rebase" between branches that have many binary changes that do
+ not conflict should be faster.
+
+ * "git rebase -i" peeks into rebase.autosquash configuration and acts as
+ if you gave --autosquash from the command line.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.2
+------------------
+
+All of the fixes in v1.7.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git merge -s recursive" (which is the default) did not handle cases
+ where a directory becomes a file (or vice versa) very well.
+
+ * "git fetch" and friends were accidentally broken for url with "+" in
+ its path, e.g. "git://git.gnome.org/gtk+".
+
+ * "git fetch $url" (i.e. without refspecs) was broken for quite some
+ time, if the current branch happen to be tracking some remote.
+
+ * "git ls-tree dir dirgarbage", when "dir" was a directory,
+ incorrectly recursed into "dir".
+
+ * "git note remove" created unnecessary extra commit when named object
+ did not have any note to begin with.
+
+ * "git rebase" did not work well if you had diff.noprefix configured.
+
+ * "git -c foo=bar subcmd" did not work well for subcmd that is not

to the value of `$HOME` and "{tilde}user/" to the specified user's
home directory. See linkgit:gitignore[5].
+core.askpass::
+ Some commands (e.g. svn and http interfaces) that interactively
+ ask for a password can be told to use an external program given
+ via the value of this variable. Can be overridden by the 'GIT_ASKPASS'
+ environment variable. If not set, fall back to the value of the
+ 'SSH_ASKPASS' environment variable or, failing that, a simple password
+ prompt. The external program shall be given a suitable prompt as
+ command line argument and write the password on its STDOUT.
+
+core.attributesfile::
+ In addition to '.gitattributes' (per-directory) and
+ '.git/info/attributes', git looks into this file for attributes
+ (see linkgit:gitattributes[5]). Path expansions are made the same
+ way as for `core.excludesfile`.
+
core.editor::
Commands such as `commit` and `tag` that lets you edit
messages by launching an editor uses the value of this
standard "a/" and "b/" depending on what is being compared. When
this configuration is in effect, reverse diff output also swaps
the order of the prefixes:
-diff.noprefix::
- If set, 'git diff' does not show any source or destination prefix.
`git diff`;;
compares the (i)ndex and the (w)ork tree;
`git diff HEAD`;;
`git diff --no-index a b`;;
compares two non-git things (1) and (2).
+diff.noprefix::
+ If set, 'git diff' does not show any source or destination prefix.
+
diff.renameLimit::
The number of files to consider when performing the copy/rename
detection; equivalent to the 'git diff' option '-l'.
will enable basic rename detection. If set to "copies" or
"copy", it will detect copies, as well.
+diff.ignoreSubmodules::
+ Sets the default value of --ignore-submodules. Note that this
+ affects only 'git diff' Porcelain, and not lower level 'diff'
+ commands such as 'git diff-files'. 'git checkout' also honors
+ this setting when reporting uncommitted changes.
+
diff.suppressBlankEmpty::
A boolean to inhibit the standard behavior of printing a space
before each empty output line. Defaults to false.
support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
environment variable. Default is false (curl will use EPSV).
+http.useragent::
+ The HTTP USER_AGENT string presented to an HTTP server. The default
+ value represents the version of the client git such as git/1.7.1.
+ This option allows you to override this value to a more common value
+ such as Mozilla/4.0. This may be necessary, for instance, if
+ connecting through a firewall that restricts HTTP connections to a set
+ of common USER_AGENT strings (but not including those like git/1.7.1).
+ Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
+
i18n.commitEncoding::
Character encoding the commit messages are stored in; git itself
does not care per se, but this information is necessary e.g. when
ignored if portable keystroke input is not available.
log.date::
- Set default date-time mode for the log command. Setting log.date
- value is similar to using 'git log'\'s --date option. The value is one of the
- following alternatives: {relative,local,default,iso,rfc,short}.
- See linkgit:git-log[1].
+ Set the default date-time mode for the 'log' command.
+ Setting a value for log.date is similar to using 'git log''s
+ `\--date` option. Possible values are `relative`, `local`,
+ `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
+ for details.
log.decorate::
Print out the ref names of any commits that are shown by the log
Whether to show a diffstat of what changed upstream since the last
rebase. False by default.
+rebase.autosquash::
+ If set to true enable '--autosquash' option by default.
+
receive.autogc::
By default, git-receive-pack will run "git-gc --auto" after
receiving data from git-push and updating refs. You can stop
URL and other values found in the `.gitmodules` file. See
linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
+submodule.<name>.ignore::
+ Defines under what circumstances "git status" and the diff family show
+ a submodule as modified. When set to "all", it will never be considered
+ modified, "dirty" will ignore all changes to the submodules work tree and
+ takes only differences between the HEAD of the submodule and the commit
+ recorded in the superproject into account. "untracked" will additionally
+ let submodules with modified tracked files in their work tree show up.
+ Using "none" (the default when this option is not set) also shows
+ submodules that have untracked files in their work tree as changed.
+ This setting overrides any setting made in .gitmodules for this submodule,
+ both settings can be overridden on the command line by using the
+ "--ignore-submodules" option.
+
tar.umask::
This variable can be used to restrict the permission bits of
tar archive entries. The default is 0002, which turns off the
appearing in diff output; see the 'pickaxe' entry in
linkgit:gitdiffcore[7] for more details.
+-G<regex>::
+ Look for differences whose added or removed line matches
+ the given <regex>.
+
--pickaxe-all::
- When `-S` finds a change, show all the changes in that
+ When `-S` or `-G` finds a change, show all the changes in that
changeset, not just the files that contain the change
in <string>.
--ignore-submodules[=<when>]::
Ignore changes to submodules in the diff generation. <when> can be
- either "untracked", "dirty" or "all", which is the default. When
+ either "none", "untracked", "dirty" or "all", which is the default
+ Using "none" will consider the submodule modified when it either contains
+ untracked or modified files or its HEAD differs from the commit recorded
+ in the superproject and can be used to override any settings of the
+ 'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When
"untracked" is used submodules are not considered dirty when they only
contain untracked content (but they are still scanned for modified
content). Using "dirty" ignores all changes to the work tree of submodules,

+Reordering and editing commits usually creates untested intermediate
+steps. You may want to check that your history editing did not break
+anything by running a test, or at least recompiling at intermediate
+points in history by using the "exec" command (shortcut "x"). You may
+do so by creating a todo list like this one:
+
+-------------------------------------------
+pick deadbee Implement feature XXX
+fixup f1a5c00 Fix to feature XXX
+exec make
+pick c0ffeee The oneline of the next commit
+edit deadbab The oneline of the commit after
+exec cd subdir; make test
+...
+-------------------------------------------
+
+The interactive rebase will stop when a command fails (i.e. exits with
+non-0 status) to give you an opportunity to fix the problem. You can
+continue with `git rebase --continue`.
+
+The "exec" command launches the command in a shell (the one specified
+in `$SHELL`, or the default shell if `$SHELL` is not set), so you can
+use shell features (like "cd", ">", ";" ...). The command is run from
+the root of the working tree.

DESCRIPTION
-----------
-This is meant to be used as a login shell for SSH accounts you want

+ in the superproject and can be used to override any settings of the
+ 'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When
"untracked" is used submodules are not considered dirty when they only
contain untracked content (but they are still scanned for modified
content). Using "dirty" ignores all changes to the work tree of submodules,
revision fetched. If unset, 'git svn' assumes this option to
be "true".
+svn.pathnameencoding::
+ This instructs git svn to recode pathnames to a given encoding.
+ It can be used by windows users and by those who work in non-utf8
+ locales to avoid corrupted file names with non-ASCII characters.
+ Valid encodings are the ones supported by Perl's Encode module.

Since the noMetadata, rewriteRoot, rewriteUUID, useSvnsyncProps and useSvmProps
options all affect the metadata generated and used by 'git svn'; they

When the browser, specified by options or configuration variables, is
not among the supported ones, then the corresponding
'browser.<tool>.cmd' configuration variable will be looked up. If this
-variable exists then 'git web--browse' will treat the specified tool
+variable exists then 'git web{litdd}browse' will treat the specified tool
as a custom command and will use a shell eval to run the command with
the URLs passed as arguments.

Interaction between checkin/checkout attributes

+Merging branches with differing checkin/checkout attributes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have added attributes to a file that cause the canonical
+repository format for that file to change, such as adding a
+clean/smudge filter or text/eol/ident attributes, merging anything
+where the attribute is not in place would normally cause merge
+conflicts.
+
+To prevent these unnecessary merge conflicts, git can be told to run a
+virtual check-out and check-in of all three stages of a file when
+resolving a three-way merge by setting the `merge.renormalize`
+configuration variable. This prevents changes caused by check-in
+conversion from causing spurious merge conflicts when a converted file
+is merged with an unconverted file.
+
+As long as a "smudge->clean" results in the same output as a "clean"
+even on files that are already smudged, this strategy will
+automatically resolve all filter-related conflicts. Filters that do
+not act in this way may cause additional merge conflicts that must be
+resolved manually.

+ This runs a virtual check-out and check-in of all three stages

This option is a more advanced form of 'subtree' strategy, where
the strategy makes a guess on how two trees must be shifted to

- nor 'commit1...commit2' notations cannot be used).
+ nor 'commit1\...commit2' notations cannot be used).

- a commit whose commit message starts with the specified text.
+ a commit whose commit message matches the specified regular expression.
This name returns the youngest matching commit which is
reachable from any ref. If the commit message starts with a
'!', you have to repeat that; the special sequence ':/!',
followed by something else than '!' is reserved for now.
+ The regular expression can match any part of the commit message. To
+ match messages starting with a string, one can use e.g. `:/^foo`.
* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree
at the given path in the tree-ish object named by the part

+merge API
+=========
+
+The merge API helps a program to reconcile two competing sets of
+improvements to some files (e.g., unregistered changes from the work
+tree versus changes involved in switching to a new branch), reporting
+conflicts if found. The library called through this API is
+responsible for a few things.
+
+ * determining which trees to merge (recursive ancestor consolidation);
+
+ * lining up corresponding files in the trees to be merged (rename
+ detection, subtree shifting), reporting edge cases like add/add
+ and rename/rename conflicts to the user;
+
+ * performing a three-way merge of corresponding files, taking
+ path-specific merge drivers (specified in `.gitattributes`)
+ into account.
+
+Low-level (single file) merge
+-----------------------------
+
+`ll_merge`::
+
+ Perform a three-way single-file merge in core. This is
+ a thin wrapper around `xdl_merge` that takes the path and
+ any merge backend specified in `.gitattributes` or
+ `.git/info/attributes` into account. Returns 0 for a
+ clean merge.
+
+The caller:
+
+1. allocates an mmbuffer_t variable for the result;
+2. allocates and fills variables with the file's original content
+ and two modified versions (using `read_mmfile`, for example);
+3. calls ll_merge();
+4. reads the output from result_buf.ptr and result_buf.size;
+5. releases buffers when finished (free(ancestor.ptr); free(ours.ptr);
+ free(theirs.ptr); free(result_buf.ptr);).
+
+If the modifications do not merge cleanly, `ll_merge` will return a
+nonzero value and `result_buf` will generally include a description of
+the conflict bracketed by markers such as the traditional `<<<<<<<`
+and `>>>>>>>`.
+
+The `ancestor_label`, `our_label`, and `their_label` parameters are
+used to label the different sides of a conflict if the merge driver
+supports this.
+
+The `flag` parameter is a bitfield:
+
+ - The `LL_OPT_VIRTUAL_ANCESTOR` bit indicates whether this is an
+ internal merge to consolidate ancestors for a recursive merge.
+
+ - The `LL_OPT_FAVOR_MASK` bits allow local conflicts to be automatically
+ resolved in favor of one side or the other (as in 'git merge-file'
+ `--ours`/`--theirs`/`--union`).
+ They can be populated by `create_ll_flag`, whose argument can be
+ `XDL_MERGE_FAVOR_OURS`, `XDL_MERGE_FAVOR_THEIRS`, or
+ `XDL_MERGE_FAVOR_UNION`.
+
+Everything else
+---------------
+
+Talk about <merge-recursive.h> and merge_file():
+
+ - merge_trees() to merge with rename detection
+ - merge_recursive() for ancestor consolidation
+ - try_merge_command() for other strategies
+ - conflict format
+ - merge options
+

If not stated otherwise, interpret the arguments as follows:
* `short` is a character for the short option
- (e.g. `\'e\'` for `-e`, use `0` to omit),
+ (e.g. `{apostrophe}e{apostrophe}` for `-e`, use `0` to omit),
* `long` is a string for the long option
(e.g. `"example"` for `\--example`, use `NULL` to omit),
The callback mechanism is as follows:
* Inside `func`, the only interesting member of the structure
- given by `opt` is the void pointer `opt->value`.
- `\*opt->value` will be the value that is saved into `var`, if you
+ given by `opt` is the void pointer `opt\->value`.
+ `\*opt\->value` will be the value that is saved into `var`, if you
use `OPT_CALLBACK()`.
- For example, do `*(unsigned long *)opt->value = 42;` to get 42
+ For example, do `*(unsigned long *)opt\->value = 42;` to get 42
into an `unsigned long` variable.
* Return value `0` indicates success and non-zero return
* `data` can be anything the `fn` callback would want to use.
+* `show_all_errors` tells whether to stop at the first error or not.

DESCRIPTION
-----------
-Converts a Subversion dumpfile (version: 2) into input suitable for
+Converts a Subversion dumpfile into input suitable for
git-fast-import(1) and similar importers. REPO is a path to a
Subversion repository mirrored on the local disk. Remote Subversion
repositories can be mirrored on local disk using the `svnsync`
Files in this format can be generated using the 'svnadmin dump' or
'svk admin dump' command.
+Dumps produced with 'svnadmin dump --deltas' (dumpfile format v3)
+are not supported.
+
OUTPUT FORMAT
-------------
The fast-import format is documented by the git-fast-import(1)
as committer, where 'user' is the value of the `svn:author` property
and 'UUID' the repository's identifier.
-To support incremental imports, 'svn-fe' will put a `git-svn-id`
-line at the end of each commit log message if passed an url on the
-command line. This line has the form `git-svn-id: URL@REVNO UUID`.
-
-Empty directories and unknown properties are silently discarded.
+To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
+the end of each commit log message if passed an url on the command
+line. This line has the form `git-svn-id: URL@REVNO UUID`.
The resulting repository will generally require further processing
to put each project in its own repository and to separate the history
BUGS
----
-Litters the current working directory with .bin files for
-persistence. Will be fixed when the svn-fe infrastructure is aware of
-a Git working directory.
+Empty directories and unknown properties are silently discarded.
+
+The exit status does not reflect whether an error was detected.

test ...
+ - Check the test coverage for your tests. See the "Test coverage"
+ below.
+
+ Don't blindly follow test coverage metrics, they're a good way to
+ spot if you've missed something. If a new function you added
+ doesn't have any coverage you're probably doing something wrong,
+ but having 100% coverage doesn't necessarily mean that you tested
+ everything.
+
+ Tests that are likely to smoke out future regressions are better
+ than tests that just inflate the coverage metrics.
+
Don't:
- exit() within a <script> part.
Skipping tests
--------------
-If you need to skip all the remaining tests you should set skip_all
-and immediately call test_done. The string you give to skip_all will
-be used as an explanation for why the test was skipped. for instance:
+If you need to skip tests you should do so be using the three-arg form
+of the test_* functions (see the "Test harness library" section
+below), e.g.:
+
+ test_expect_success PERL 'I need Perl' "
+ '$PERL_PATH' -e 'hlagh() if unf_unf()'
+ "
+
+The advantage of skipping tests like this is that platforms that don't
+have the PERL and other optional dependencies get an indication of how
+many tests they're missing.
+
+If the test code is too hairy for that (i.e. does a lot of setup work
+outside test assertions) you can also skip all remaining tests by
+setting skip_all and immediately call test_done:
if ! test_have_prereq PERL
then
test_done
fi
+The string you give to skip_all will be used as an explanation for why
+the test was skipped.
+
End with test_done
------------------
test_expect_success TTY 'git --paginate rev-list uses a pager' \
' ... '
+ You can also supply a comma-separated list of prerequisites, in the
+ rare case where your test depends on more than one:
+
+ test_expect_success PERL,PYTHON 'yo dawg' \
+ ' test $(perl -E 'print eval "1 +" . qx[python -c "print 2"]') == "4" '
+
- test_expect_failure [<prereq>] <message> <script>
This is NOT the opposite of test_expect_success, but is used
- test_set_prereq SOME_PREREQ
Set a test prerequisite to be used later with test_have_prereq. The
- test-lib will set some prerequisites for you, e.g. PERL and PYTHON
- which are derived from ./GIT-BUILD-OPTIONS (grep test_set_prereq
- test-lib.sh for more). Others you can set yourself and use later
- with either test_have_prereq directly, or the three argument
- invocation of test_expect_success and test_expect_failure.
+ test-lib will set some prerequisites for you, see the
+ "Prerequisites" section below for a full list of these.
+
+ Others you can set yourself and use later with either
+ test_have_prereq directly, or the three argument invocation of
+ test_expect_success and test_expect_failure.
- test_have_prereq SOME PREREQ
<expected> file. This behaves like "cmp" but produces more
helpful output when the test is run with "-v" option.
+ - test_path_is_file <file> [<diagnosis>]
+ test_path_is_dir <dir> [<diagnosis>]
+ test_path_is_missing <path> [<diagnosis>]
+
+ Check whether a file/directory exists or doesn't. <diagnosis> will
+ be displayed if the test fails.
+
- test_when_finished <script>
Prepend <script> to a list of commands to run to clean up
...
'
+Prerequisites
+-------------
+
+These are the prerequisites that the test library predefines with
+test_have_prereq.
+
+See the prereq argument to the test_* functions in the "Test harness
+library" section above and the "test_have_prereq" function for how to
+use these, and "test_set_prereq" for how to define your own.
+
+ - PERL & PYTHON
+
+ Git wasn't compiled with NO_PERL=YesPlease or
+ NO_PYTHON=YesPlease. Wrap any tests that need Perl or Python in
+ these.
+
+ - POSIXPERM
+
+ The filesystem supports POSIX style permission bits.
+
+ - BSLASHPSPEC
+
+ Backslashes in pathspec are not directory separators. This is not
+ set on Windows. See 6fd1106a for details.
+
+ - EXECKEEPSPID
+
+ The process retains the same pid across exec(2). See fb9a2bea for
+ details.
+
+ - SYMLINKS
+
+ The filesystem we're on supports symbolic links. E.g. a FAT
+ filesystem doesn't support these. See 704a3143 for details.
+
+ - SANITY
+
+ Test is not run by root user, and an attempt to write to an
+ unwritable file is expected to fail correctly.
Tips for Writing Tests
----------------------
validation in one place. Your test also ends up needing
updating when such a change to the internal happens, so do _not_
do it and leave the low level of validation to t0000-basic.sh.
+
+Test coverage
+-------------
+
+You can use the coverage tests to find code paths that are not being
+used or properly exercised yet.
+
+To do that, run the coverage target at the top-level (not in the t/
+directory):
+
+ make coverage
+
+That'll compile Git with GCC's coverage arguments, and generate a test
+report with gcov after the tests finish. Running the coverage tests
+can take a while, since running the tests in parallel is incompatible
+with GCC's coverage mode.
+
+After the tests have run you can generate a list of untested
+functions:
+
+ make coverage-untested-functions
+
+You can also generate a detailed per-file HTML report using the
+Devel::Cover module. To install it do:
+
+ # On Debian or Ubuntu:
+ sudo aptitude install libdevel-cover-perl
+
+ # From the CPAN with cpanminus
+ curl -L http://cpanmin.us | perl - --sudo --self-upgrade
+ cpanm --sudo Devel::Cover
+
+Then, at the top-level:
+
+ make cover_db_html
+
+That'll generate a detailed cover report in the "cover_db_html"
+directory, which you can then copy to a webserver, or inspect locally
+in a browser.
+
+Smoke testing
+-------------
+
+The Git test suite has support for smoke testing. Smoke testing is
+when you submit the results of a test run to a central server for
+analysis and aggregation.
+
+Running a smoke tester is an easy and valuable way of contributing to
+Git development, particularly if you have access to an uncommon OS on
+obscure hardware.
+
+After building Git you can generate a smoke report like this in the
+"t" directory:
+
+ make clean smoke
+
+You can also pass arguments via the environment. This should make it
+faster:
+
+ GIT_TEST_OPTS='--root=/dev/shm' TEST_JOBS=10 make clean smoke
+
+The "smoke" target will run the Git test suite with Perl's
+"TAP::Harness" module, and package up the results in a .tar.gz archive
+with "TAP::Harness::Archive". The former is included with Perl v5.10.1
+or later, but you'll need to install the latter from the CPAN. See the
+"Test coverage" section above for how you might do that.
+
+Once the "smoke" target finishes you'll see a message like this:
+
+ TAP Archive created at <path to git>/t/test-results/git-smoke.tar.gz
+
+To upload the smoke report you need to have curl(1) installed, then
+do:
+
+ make smoke_report
+
+To upload the report anonymously. Hopefully that'll return something
+like "Reported #7 added.".
+
+If you're going to be uploading reports frequently please request a
+user account by E-Mailing gitsmoke@v.nix.is. Once you have a username
+and password you'll be able to do:
+
+ SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> make smoke_report
+
+You can also add an additional comment to attach to the report, and/or
+a comma separated list of tags:
+
+ SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> \
+ SMOKE_COMMENT=<comment> SMOKE_TAGS=<tags> \
+ make smoke_report
+
+Once the report is uploaded it'll be made available at
+http://smoke.git.nix.is, here's an overview of Recent Smoke Reports
+for Git:
+
+ http://smoke.git.nix.is/app/projects/smoke_reports/1
+
+The reports will also be mirrored to GitHub every few hours:
+
+ http://github.com/gitsmoke/smoke-reports
+
+The Smolder SQLite database is also mirrored and made available for
+download:
+
+ http://github.com/gitsmoke/smoke-database
+
+Note that the database includes hashed (with crypt()) user passwords
+and E-Mail addresses. Don't use a valuable password for the smoke
+service if you have an account, or an E-Mail address you don't want to
+be publicly known. The user accounts are just meant to be convenient
+labels, they're not meant to be secure.

+line_buffer API
+===============
+
+The line_buffer library provides a convenient interface for
+mostly-line-oriented input.
+
+Each line is not permitted to exceed 10000 bytes. The provided
+functions are not thread-safe or async-signal-safe, and like
+`fgets()`, they generally do not function correctly if interrupted
+by a signal without SA_RESTART set.
+
+Calling sequence
+----------------
+
+The calling program:
+
+ - specifies a file to read with `buffer_init`
+ - processes input with `buffer_read_line`, `buffer_read_string`,
+ `buffer_skip_bytes`, and `buffer_copy_bytes`
+ - closes the file with `buffer_deinit`, perhaps to start over and
+ read another file.
+
+Before exiting, the caller can use `buffer_reset` to deallocate
+resources for the benefit of profiling tools.
+
+Functions
+---------
+
+`buffer_init`::
+ Open the named file for input. If filename is NULL,
+ start reading from stdin. On failure, returns -1 (with
+ errno indicating the nature of the failure).
+
+`buffer_deinit`::
+ Stop reading from the current file (closing it unless
+ it was stdin). Returns nonzero if `fclose` fails or
+ the error indicator was set.
+
+`buffer_read_line`::
+ Read a line and strip off the trailing newline.
+ On failure or end of file, returns NULL.
+
+`buffer_read_string`::
+ Read `len` characters of input or up to the end of the
+ file, whichever comes first. Returns NULL on error.
+ Returns whatever characters were read (possibly "")
+ for end of file.
+
+`buffer_copy_bytes`::
+ Read `len` bytes of input and dump them to the standard output
+ stream. Returns early for error or end of file.
+
+`buffer_skip_bytes`::
+ Discards `len` bytes from the input stream (stopping early
+ if necessary because of an error or eof).
+
+`buffer_reset`::
+ Deallocates non-static buffers.

+string_pool API
+===============
+
+The string_pool API provides facilities for replacing strings
+with integer keys that can be more easily compared and stored.
+The facilities are designed so that one could teach Git without
+too much trouble to store the information needed for these keys to
+remain valid over multiple executions.
+
+Functions
+---------
+
+pool_intern::
+ Include a string in the string pool and get its key.
+ If that string is already in the pool, retrieves its
+ existing key.
+
+pool_fetch::
+ Retrieve the string associated to a given key.
+
+pool_tok_r::
+ Extract the key of the next token from a string.
+ Interface mimics strtok_r.
+
+pool_print_seq::
+ Print a sequence of strings named by key to a file, using the
+ specified delimiter to separate them.
+
+ If NULL (key ~0) appears in the sequence, the sequence ends
+ early.
+
+pool_tok_seq::
+ Split a string into tokens, storing the keys of segments
+ into a caller-provided array.
+
+ Unless sz is 0, the array will always be ~0-terminated.
+ If there is not enough room for all the tokens, the
+ array holds as many tokens as fit in the entries before
+ the terminating ~0. Return value is the index after the
+ last token, or sz if the tokens did not fit.
+
+pool_reset::
+ Deallocate storage for the string pool.

+Motivation
+==========
+
+Treaps provide a memory-efficient binary search tree structure.
+Insertion/deletion/search are about as about as fast in the average
+case as red-black trees and the chances of worst-case behavior are
+vanishingly small, thanks to (pseudo-)randomness. The bad worst-case
+behavior is a small price to pay, given that treaps are much simpler
+to implement.
+
+API
+===
+
+The trp API generates a data structure and functions to handle a
+large growing set of objects stored in a pool.
+
+The caller:
+
+. Specifies parameters for the generated functions with the
+ trp_gen(static, foo_, ...) macro.
+
+. Allocates a `struct trp_root` variable and sets it to {~0}.
+
+. Adds new nodes to the set using `foo_insert`.
+
+. Can find a specific item in the set using `foo_search`.
+
+. Can iterate over items in the set using `foo_first` and `foo_next`.
+
+. Can remove an item from the set using `foo_remove`.
+
+Example:
+
+----
+struct ex_node {
+ const char *s;
+ struct trp_node ex_link;
+};
+static struct trp_root ex_base = {~0};
+obj_pool_gen(ex, struct ex_node, 4096);
+trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
+struct ex_node *item;
+
+item = ex_pointer(ex_alloc(1));
+item->s = "hello";
+ex_insert(&ex_base, item);
+item = ex_pointer(ex_alloc(1));
+item->s = "goodbye";
+ex_insert(&ex_base, item);
+for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
+ printf("%s\n", item->s);
+----
+
+Functions
+---------
+
+trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
+
+ Generate a type-specific treap implementation.
++
+. The storage class for generated functions will be 'attr' (e.g., `static`).
+. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
+. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
+ This type must be a struct with at least one `struct trp_node` field
+ to point to its children.
+. The field used to access child nodes will be 'link_field'.
+. All treap nodes must lie in the 'pool' object pool.
+. Treap nodes must be totally ordered by the 'cmp' relation, with the
+ following prototype:
++
+int (*cmp)(node_type \*a, node_type \*b)
++
+and returning a value less than, equal to, or greater than zero
+according to the result of comparison.
+
+void foo_insert(struct trp_root *treap, node_type \*node)::
+
+ Insert node into treap. If inserted multiple times,
+ a node will appear in the treap multiple times.
+
+void foo_remove(struct trp_root *treap, node_type \*node)::
+
+ Remove node from treap. Caller must ensure node is
+ present in treap before using this function.
+
+node_type *foo_search(struct trp_root \*treap, node_type \*key)::
+
+ Search for a node that matches key. If no match is found,
+ result is NULL.
+
+node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
+
+ Like `foo_search`, but if if the key is missing return what
+ would be key's successor, were key in treap (NULL if no
+ successor).
+
+node_type *foo_first(struct trp_root \*treap)::
+
