+Git v2.10.1 Release Notes
+=========================
+
+Fixes since v2.10
+-----------------
+
+ * Clarify various ways to specify the "revision ranges" in the
+ documentation.
+
+ * "diff-highlight" script (in contrib/) learned to work better with
+ "git log -p --graph" output.
+
+ * The test framework left the number of tests and success/failure
+ count in the t/test-results directory, keyed by the name of the
+ test script plus the process ID. The latter however turned out not
+ to serve any useful purpose. The process ID part of the filename
+ has been removed.
+
+ * Having a submodule whose ".git" repository is somehow corrupt
+ caused a few commands that recurse into submodules loop forever.
+
+ * "git symbolic-ref -d HEAD" happily removes the symbolic ref, but
+ the resulting repository becomes an invalid one. Teach the command
+ to forbid removal of HEAD.
+
+ * A test spawned a short-lived background process, which sometimes
+ prevented the test directory from getting removed at the end of the
+ script on some platforms.
+
+ * Update a few tests that used to use GIT_CURL_VERBOSE to use the
+ newer GIT_TRACE_CURL.
+
+Also contains minor documentation updates and code clean-ups.

+Git 2.11 Release Notes
+======================
+
+Updates since v2.10
+-------------------
+
+UI, Workflows & Features
+
+ * "git format-patch --cover-letter HEAD^" to format a single patch
+ with a separate cover letter now numbers the output as [PATCH 0/1]
+ and [PATCH 1/1] by default.
+
+ * An incoming "git push" that attempts to push too many bytes can now
+ be rejected by setting a new configuration variable at the receiving
+ end.
+
+ * "git nosuchcommand --help" said "No manual entry for gitnosuchcommand",
+ which was not intuitive, given that "git nosuchcommand" said "git:
+ 'nosuchcommand' is not a git command".
+
+ * "git clone --resurse-submodules --reference $path $URL" is a way to
+ reduce network transfer cost by borrowing objects in an existing
+ $path repository when cloning the superproject from $URL; it
+ learned to also peek into $path for presense of corresponding
+ repositories of submodules and borrow objects from there when able.
+
+ * The "git diff --submodule={short,log}" mechanism has been enhanced
+ to allow "--submodule=diff" to show the patch between the submodule
+ commits bound to the superproject.
+
+ * Even though "git hash-objects", which is a tool to take an
+ on-filesystem data stream and put it into the Git object store,
+ allowed to perform the "outside-world-to-Git" conversions (e.g.
+ end-of-line conversions and application of the clean-filter), and
+ it had the feature on by default from very early days, its reverse
+ operation "git cat-file", which takes an object from the Git object
+ store and externalize for the consumption by the outside world,
+ lacked an equivalent mechanism to run the "Git-to-outside-world"
+ conversion. The command learned the "--filters" option to do so.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The delta-base-cache mechanism has been a key to the performance in
+ a repository with a tightly packed packfile, but it did not scale
+ well even with a larger value of core.deltaBaseCacheLimit.
+
+ * Enhance "git status --porcelain" output by collecting more data on
+ the state of the index and the working tree files, which may
+ further be used to teach git-prompt (in contrib/) to make fewer
+ calls to git.
+
+ * Extract a small helper out of the function that reads the authors
+ script file "git am" internally uses.
+ (merge a77598e jc/am-read-author-file later to maint).
+
+ * Lifts calls to exit(2) and die() higher in the callchain in
+ sequencer.c files so that more helper functions in it can be used
+ by callers that want to handle error conditions themselves.
+
+ * "git am" has been taught to make an internal call to "git apply"'s
+ innards without spawning the latter as a separate process.
+
+ * The ref-store abstraction was introduced to the refs API so that we
+ can plug in different backends to store references.
+
+ * The "unsigned char sha1[20]" to "struct object_id" conversion
+ continues. Notable changes in this round includes that ce->sha1,
+ i.e. the object name recorded in the cache_entry, turns into an
+ object_id.
+
+ * JGit can show a fake ref "capabilities^{}" to "git fetch" when it
+ does not advertise any refs, but "git fetch" was not prepared to
+ see such an advertisement. When the other side disconnects without
+ giving any ref advertisement, we used to say "there may not be a
+ repository at that URL", but we may have seen other advertisement
+ like "shallow" and ".have" in which case we definitely know that a
+ repository is there. The code to detect this case has also been
+ updated.
+
+ * Some codepaths in "git pack-objects" were not ready to use an
+ existing pack bitmap; now they are and as the result they have
+ become faster.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.10
+-----------------
+
+Unless otherwise noted, all the fixes since v2.9 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * Clarify various ways to specify the "revision ranges" in the
+ documentation.
+
+ * "diff-highlight" script (in contrib/) learned to work better with
+ "git log -p --graph" output.
+
+ * The test framework left the number of tests and success/failure
+ count in the t/test-results directory, keyed by the name of the
+ test script plus the process ID. The latter however turned out not
+ to serve any useful purpose. The process ID part of the filename
+ has been removed.
+
+ * Having a submodule whose ".git" repository is somehow corrupt
+ caused a few commands that recurse into submodules loop forever.
+
+ * "git symbolic-ref -d HEAD" happily removes the symbolic ref, but
+ the resulting repository becomes an invalid one. Teach the command
+ to forbid removal of HEAD.
+
+ * A test spawned a short-lived background process, which sometimes
+ prevented the test directory from getting removed at the end of the
+ script on some platforms.
+
+ * Update a few tests that used to use GIT_CURL_VERBOSE to use the
+ newer GIT_TRACE_CURL.
+
+ * "git pack-objects --include-tag" was taught that when we know that
+ we are sending an object C, we want a tag B that directly points at
+ C but also a tag A that points at the tag B. We used to miss the
+ intermediate tag B in some cases.
+ (merge b773dde jk/pack-tag-of-tag later to maint).
+
+ * Update Japanese translation for "git-gui".
+ (merge 02748bc sy/git-gui-i18n-ja later to maint).
+
+ * "git fetch http::/site/path" did not die correctly and segfaulted
+ instead.
+ (merge d63ed6e jk/fix-remote-curl-url-wo-proto later to maint).
+
+ * "git commit-tree" stopped reading commit.gpgsign configuration
+ variable that was meant for Porcelain "git commit" in Git 2.9; we
+ forgot to update "git gui" to look at the configuration to match
+ this change.
+ (merge f14a310 js/git-gui-commit-gpgsign later to maint).
+
+ * "git add --chmod=+x" added recently lacked documentation, which has
+ been corrected.
+ (merge 7ef7903 et/add-chmod-x later to maint).
+
+ * "git log --cherry-pick" used to include merge commits as candidates
+ to be matched up with other commits, resulting a lot of wasted time.
+ The patch-id generation logic has been updated to ignore merges to
+ avoid the wastage.
+ (merge 7c81040 jk/patch-ids-no-merges later to maint).
+
+ * The http transport (with curl-multi option, which is the default
+ these days) failed to remove curl-easy handle from a curlm session,
+ which led to unnecessary API failures.
+ (merge 2abc848 ew/http-do-not-forget-to-call-curl-multi-remove-handle later to maint).
+
+ * There were numerous corner cases in which the configuration files
+ are read and used or not read at all depending on the directory a
+ Git command was run, leading to inconsistent behaviour. The code
+ to set-up repository access at the beginning of a Git process has
+ been updated to fix them.
+ (merge 4d0efa1 jk/setup-sequence-update later to maint).
+
+ * "git diff -W" output needs to extend the context backward to
+ include the header line of the current function and also forward to
+ include the body of the entire current function up to the header
+ line of the next one. This process may have to merge to adjacent
+ hunks, but the code forgot to do so in some cases.
+ (merge 45d2f75 rs/xdiff-merge-overlapping-hunks-for-W-context later to maint).
+
+ * Performance tests done via "t/perf" did not use the same set of
+ build configuration if the user relied on autoconf generated
+ configuration.
+ (merge cd5c281 ks/perf-build-with-autoconf later to maint).
+
+ * "git format-patch --base=..." feature that was recently added
+ showed the base commit information after "-- " e-mail signature
+ line, which turned out to be inconvenient. The base information
+ has been moved above the signature line.
+ (merge 480871e jt/format-patch-base-info-above-sig later to maint).
+
+ * More i18n.
+ (merge 43073f8 va/i18n later to maint).
+
+ * Even when "git pull --rebase=preserve" (and the underlying "git
+ rebase --preserve") can complete without creating any new commit
+ (i.e. fast-forwards), it still insisted on having a usable ident
+ information (read: user.email is set correctly), which was less
+ than nice. As the underlying commands used inside "git rebase"
+ would fail with a more meaningful error message and advice text
+ when the bogus ident matters, this extra check was removed.
+ (merge 1e461c4 jk/rebase-i-drop-ident-check later to maint).
+
+ * "git gc --aggressive" used to limit the delta-chain length to 250,
+ which is way too deep for gaining additional space savings and is
+ detrimental for runtime performance. The limit has been reduced to
+ 50.
+ (merge 07e7dbf jk/reduce-gc-aggressive-depth later to maint).
+
+ * Other minor doc, test and build updates and code cleanups.
+ (merge e78d57e bw/pathspec-remove-unused-extern-decl later to maint).
+ (merge ce25e4c rs/checkout-some-states-are-const later to maint).

+Git v2.9.4 Release Notes
+========================
+
+Fixes since v2.9.3
+------------------
+
+ * There are certain house-keeping tasks that need to be performed at
+ the very beginning of any Git program, and programs that are not
+ built-in commands had to do them exactly the same way as "git"
+ potty does. It was easy to make mistakes in one-off standalone
+ programs (like test helpers). A common "main()" function that
+ calls cmd_main() of individual program has been introduced to
+ make it harder to make mistakes.
+
+ * "git merge" with renormalization did not work well with
+ merge-recursive, due to "safer crlf" conversion kicking in when it
+ shouldn't.
+
+ * The reflog output format is documented better, and a new format
+ --date=unix to report the seconds-since-epoch (without timezone)
+ has been added.
+
+ * "git push --force-with-lease" already had enough logic to allow
+ ensuring that such a push results in creation of a ref (i.e. the
+ receiving end did not have another push from sideways that would be
+ discarded by our force-pushing), but didn't expose this possibility
+ to the users. It does so now.
+
+ * "import-tars" fast-import script (in contrib/) used to ignore a
+ hardlink target and replaced it with an empty file, which has been
+ corrected to record the same blob as the other file the hardlink is
+ shared with.
+
+ * "git mv dir non-existing-dir/" did not work in some environments
+ the same way as existing mainstream platforms. The code now moves
+ "dir" to "non-existing-dir", without relying on rename("A", "B/")
+ that strips the trailing slash of '/'.
+
+ * The "t/" hierarchy is prone to get an unusual pathname; "make test"
+ has been taught to make sure they do not contain paths that cannot
+ be checked out on Windows (and the mechanism can be reusable to
+ catch pathnames that are not portable to other platforms as need
+ arises).
+
+ * When "git merge-recursive" works on history with many criss-cross
+ merges in "verbose" mode, the names the command assigns to the
+ virtual merge bases could have overwritten each other by unintended
+ reuse of the same piece of memory.
+
+ * "git checkout --detach <branch>" used to give the same advice
+ message as that is issued when "git checkout <tag>" (or anything
+ that is not a branch name) is given, but asking with "--detach" is
+ an explicit enough sign that the user knows what is going on. The
+ advice message has been squelched in this case.
+
+ * "git difftool" by default ignores the error exit from the backend
+ commands it spawns, because often they signal that they found
+ differences by exiting with a non-zero status code just like "diff"
+ does; the exit status codes 126 and above however are special in
+ that they are used to signal that the command is not executable,
+ does not exist, or killed by a signal. "git difftool" has been
+ taught to notice these exit status codes.
+
+ * On Windows, help.browser configuration variable used to be ignored,
+ which has been corrected.
+
+ * The "git -c var[=val] cmd" facility to append a configuration
+ variable definition at the end of the search order was described in
+ git(1) manual page, but not in git-config(1), which was more likely
+ place for people to look for when they ask "can I make a one-shot
+ override, and if so how?"
+
+ * The tempfile (hence its user lockfile) API lets the caller to open
+ a file descriptor to a temporary file, write into it and then
+ finalize it by first closing the filehandle and then either
+ removing or renaming the temporary file. When the process spawns a
+ subprocess after obtaining the file descriptor, and if the
+ subprocess has not exited when the attempt to remove or rename is
+ made, the last step fails on Windows, because the subprocess has
+ the file descriptor still open. Open tempfile with O_CLOEXEC flag
+ to avoid this (on Windows, this is mapped to O_NOINHERIT).
+
+Also contains minor documentation updates and code clean-ups.

DESCRIPTION
-----------
In its first form, the command provides the content or the type of an object in

-object type, or `-s` is used to find the object size, or `--textconv` is used
-(which implies type "blob").
+object type, or `-s` is used to find the object size, or `--textconv` or

In the second form, a list of objects (separated by linefeeds) is provided on
-stdin, and the SHA-1, type, and size of each object is printed on stdout.
+stdin, and the SHA-1, type, and size of each object is printed on stdout. The
+output format can be overridden using the optional `<format>` argument. If
+either `--textconv` or `--filters` was specified, the input is expected to
+list the object names followed by the path name, separated by a single white
+space, so that the appropriate drivers can be determined.
OPTIONS
-------
--textconv::
Show the content as transformed by a textconv filter. In this case,
- <object> has be of the form <tree-ish>:<path>, or :<path> in order
- to apply the filter to the content recorded in the index at <path>.
+ <object> has to be of the form <tree-ish>:<path>, or :<path> in
+ order to apply the filter to the content recorded in the index at
+ <path>.
+
+--filters::
+ Show the content as converted by the filters configured in
+ the current working tree for the given <path> (i.e. smudge filters,
+ end-of-line conversion, etc). In this case, <object> has to be of
+ the form <tree-ish>:<path>, or :<path>.
+
+--path=<path>::
+ For use with --textconv or --filters, to allow specifying an object
+ name and a path separately, e.g. when it is difficult to figure out
+ the revision from which the blob came.
--batch::
--batch=<format>::
Print object information and contents for each object provided
- on stdin. May not be combined with any other options or arguments.
- See the section `BATCH OUTPUT` below for details.
+ on stdin. May not be combined with any other options or arguments
+ except `--textconv` or `--filters`, in which case the input lines
+ also need to specify the path, separated by white space. See the
+ section `BATCH OUTPUT` below for details.

--batch-check=<format>::
Print object information for each object provided on stdin. May
- not be combined with any other options or arguments. See the
+ not be combined with any other options or arguments except
+ `--textconv` or `--filters`, in which case the input lines also

------------
GIT
$ git log -g -2 HEAD
------------
+ARGUMENT DISAMBIGUATION
+-----------------------
+
+When there is only one argument given and it is not `--` (e.g. "git
+checkout abc"), and when the argument is both a valid `<tree-ish>`
+(e.g. a branch "abc" exists) and a valid `<pathspec>` (e.g. a file
+or a directory whose name is "abc" exists), Git would usually ask
+you to disambiguate. Because checking out a branch is so common an
+operation, however, "git checkout abc" takes "abc" as a `<tree-ish>`
+in such a situation. Use `git checkout -- <pathspec>` if you want
+to checkout these paths out of the index.

Importing a CVS archive
-----------------------
+NOTE: These instructions use the `git-cvsimport` script which ships with
+git, but other importers may provide better results. See the note in
+linkgit:git-cvsimport[1] for other options.
+
First, install version 2.1 or higher of cvsps from
-http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
+https://github.com/andreyvit/cvsps[https://github.com/andreyvit/cvsps] and make
sure it is in your path. Then cd to a checked out CVS working directory
of the project you are interested in and run linkgit:git-cvsimport[1]:
