-[[Note that none of these are not merged to 'master' as of this writing
-but they will be before 1.6.0 happens]]
-
With the default Makefile settings, most of the programs are now
-installed outside your $PATH, except for "git", "gitk", "git-gui" and
+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
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
--------------------
* 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. We used to prevent them from triggering by default by
- relying on the fact that we install them as unexecutable, but on
- some filesystems this approach does not work. Instead of running
- "chmod +x" on them, the users who want to activate these samples
- as-is can now rename them dropping *.sample suffix.
+ *.sample.
* perl's in-place edit (-i) does not work well without backup files on Windows;
some tests are rewritten to cope with this.
* Updated howto/update-hook-example
-* Got rid of usage of "git-foo" from the tutorial.
+* 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.)
-* even more documentation pages are now accessible via "man" and "git help".
+* 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.
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.
(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.
-* Original SHA-1 value for "update-ref -d" is optional now.
+* 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.
- * diff -c/--cc showed unnecessary "deletion" lines at the context
- boundary (needs backmerge to maint).
+ * 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-clone <src> <dst>" did not create leading directories for <dst>
- like the scripted version used to do (needs backport to maint).
+ * "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.
