Updates since v2.12
-------------------
doing other things, output from reset seeped out). These, and
other chattyness has been fixed.
+ * "git merge <message> HEAD <commit>" syntax that has been deprecated
+ since October 2007 has been removed.
+
+ * The refs completion for large number of refs has been sped up,
+ partly by giving up disambiguating ambiguous refs and partly by
+ eliminating most of the shell processing between 'git for-each-ref'
+ and 'ls-remote' and Bash's completion facility.
+
+ * On many keyboards, typing "@{" involves holding down SHIFT key and
+ one can easily end up with "@{Up..." when typing "@{upstream}". As
+ the upstream/push keywords do not appear anywhere else in the syntax,
+ we can safely accept them case insensitively without introducing
+ ambiguity or confusion to solve this.
+
+ * "git tag/branch/for-each-ref" family of commands long allowed to
+ filter the refs by "--contains X" (show only the refs that are
+ descendants of X), "--merged X" (show only the refs that are
+ ancestors of X), "--no-merged X" (show only the refs that are not
+ ancestors of X). One curious omission, "--no-contains X" (show
+ only the refs that are not descendants of X) has been added to
+ them.
+
+ * The default behaviour of "git log" in an interactive session has
+ been changed to enable "--decorate".
+
+ * The output from "git status --short" has been extended to show
+ various kinds of dirtyness in submodules differently; instead of to
+ "M" for modified, 'm' and '?' can be shown to signal changes only
+ to the working tree of the submodule but not the commit that is
+ checked out.
+
+ * Allow the http.postbuffer configuration variable to be set to a
+ size that can be expressed in size_t, which can be larger than
+ ulong on some platforms.
+
+ * "git rebase" learns "--signoff" option.
+
+ * The completion script (in contrib/) learned to complete "git push
+ --delete b<TAB>" to complete branch name to be deleted.
+
+ * "git worktree add --lock" allows to lock a worktree immediately
+ after it's created. This helps prevent a race between "git worktree
+ add; git worktree lock" and "git worktree prune".
+
+ * Completion for "git checkout <branch>" that auto-creates the branch
+ out of a remote tracking branch can now be disabled, as this
+ completion often gets in the way when completing to checkout an
+ existing local branch that happens to share the same prefix with
+ bunch of remote tracking branches.

Performance, Internal Implementation, Development Support etc.
older one and the newer one interoperate happily has now become
possible.
- * "uchar [40]" to "struct object_id" conversion continues.
-
* "git tag --contains" used to (ab)use the object bits to keep track
of the state of object reachability without clearing them after
use; this has been cleaned up and made to use the newer commit-slab
* An earlier version of sha1dc/sha1.c that was merged to 'master'
compiled incorrectly on Windows, which has been fixed.
+ * "what URL do we want to update this submodule?" and "are we
+ interested in this submodule?" are split into two distinct
+ concepts, and then the way used to express the latter got extended,
+ paving a way to make it easier to manage a project with many
+ submodules and make it possible to later extend use of multiple
+ worktrees for a project with submodules.
+
+ * Some debugging output from "git describe" were marked for l10n,
+ but some weren't. Mark missing ones for l10n.
+
+ * Define a new task in .travis.yml that triggers a test session on
+ Windows run elsewhere.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * The "submodule" specific field in the ref_store structure is
+ replaced with a more generic "gitdir" that can later be used also
+ when dealing with ref_store that represents the set of refs visible
+ from the other worktrees.
+
+ * The string-list API used a custom reallocation strategy that was
+ very inefficient, instead of using the usual ALLOC_GROW() macro,
+ which has been fixed.
+ (merge 950a234cbd jh/string-list-micro-optim later to maint).
+
+ * In a 2- and 3-way merge of trees, more than one source trees often
+ end up sharing an identical subtree; optimize by not reading the
+ same tree multiple times in such a case.
+ (merge d12a8cf0af jh/unpack-trees-micro-optim later to maint).
+
+ * The index file has a trailing SHA-1 checksum to detect file
+ corruption, and historically we checked it every time the index
+ file is used. Omit the validation during normal use, and instead
+ verify only in "git fsck".
+
+ * Having a git command on the upstream side of a pipe in a test
+ script will hide the exit status from the command, which may cause
+ us to fail to notice a breakage; rewrite tests in a script to avoid
+ this issue.
+
+ * Travis CI learns to run coccicheck.
+
+ * "git checkout" that handles a lot of paths has been optimized by
+ reducing the number of unnecessary checks of paths in the
+ has_dir_name() function.
+
+ * The internals of the refs API around the cached refs has been
+ streamlined.
+
+ * Output from perf tests have been updated to align their titles.
Also contains various documentation updates and code clean-ups.
* Fix for NO_PTHREADS option.
(merge 2225e1ea20 bw/grep-recurse-submodules later to maint).
+ * Git now avoids blindly falling back to ".git" when the setup
+ sequence said we are _not_ in Git repository. A corner case that
+ happens to work right now may be broken by a call to die("BUG").
+ (merge b1ef400eec jk/no-looking-at-dotgit-outside-repo-final later to maint).
+
+ * A few commands that recently learned the "--recurse-submodule"
+ option misbehaved when started from a subdirectory of the
+ superproject.
+ (merge b2dfeb7c00 bw/recurse-submodules-relative-fix later to maint).
+
+ * FreeBSD implementation of getcwd(3) behaved differently when an
+ intermediate directory is unreadable/unsearchable depending on the
+ length of the buffer provided, which our strbuf_getcwd() was not
+ aware of. strbuf_getcwd() has been taught to cope with it better.
+ (merge a54e938e5b rs/freebsd-getcwd-workaround later to maint).
+
+ * A recent update to "rebase -i" stopped running hooks for the "git
+ commit" command during "reword" action, which has been fixed.
+
+ * Removing an entry from a notes tree and then looking another note
+ entry from the resulting tree using the internal notes API
+ functions did not work as expected. No in-tree users of the API
+ has such access pattern, but it still is worth fixing.
+
+ * "git receive-pack" could have been forced to die by attempting
+ allocate an unreasonably large amount of memory with a crafted push
+ certificate; this has been fixed.
+ (merge f2214dede9 bc/push-cert-receive-fix later to maint).
+
+ * Update error handling for codepath that deals with corrupt loose
+ objects.
+ (merge 51054177b3 jk/loose-object-info-report-error later to maint).
+
+ * "git diff --submodule=diff" learned to work better in a project
+ with a submodule that in turn has its own submodules.
+ (merge 17b254cda6 sb/show-diff-for-submodule-in-diff-fix later to maint).
+
+ * Update the build dependency so that an update to /usr/bin/perl
+ etc. result in recomputation of perl.mak file.
+ (merge c59c4939c2 ab/regen-perl-mak-with-different-perl later to maint).
+
+ * "git push --recurse-submodules --push-option=<string>" learned to
+ propagate the push option recursively down to pushes in submodules.
+
+ * If a patch e-mail had its first paragraph after an in-body header
+ indented (even after a blank line after the in-body header line),
+ the indented line was mistook as a continuation of the in-body
+ header. This has been fixed.
+ (merge fd1062e52e lt/mailinfo-in-body-header-continuation later to maint).
+
+ * Clean up fallouts from recent tightening of the set-up sequence,
+ where Git barfs when repository information is accessed without
+ first ensuring that it was started in a repository.
+ (merge bccb22cbb1 jk/no-looking-at-dotgit-outside-repo later to maint).
+
+ * "git p4" used "name-rev HEAD" when it wants to learn what branch is
+ checked out; it should use "symbolic-ref HEAD".
+ (merge eff451101d ld/p4-current-branch-fix later to maint).
+
+ * "http.proxy" set to an empty string is used to disable the usage of
+ proxy. We broke this early last year.
+ (merge ae51d91105 sr/http-proxy-configuration-fix later to maint).
+
+ * $GIT_DIR may in some cases be normalized with all symlinks resolved
+ while "gitdir" path expansion in the pattern does not receive the
+ same treatment, leading to incorrect mismatch. This has been fixed.
+
+ * "git submodule" script does not work well with strange pathnames.
+ Protect it from a path with slashes in them, at least.
+
+ * "git fetch-pack" was not prepared to accept ERR packet that the
+ upload-pack can send with a human-readable error message. It
+ showed the packet contents with ERR prefix, so there was no data
+ loss, but it was redundant to say "ERR" in an error message.
+ (merge 8e2c7bef03 jt/fetch-pack-error-reporting later to maint).
+
+ * "ls-files --recurse-submodules" did not quite work well in a
+ project with nested submodules.
+
+ * gethostname(2) may not NUL terminate the buffer if hostname does
+ not fit; unfortunately there is no easy way to see if our buffer
+ was too small, but at least this will make sure we will not end up
+ using garbage past the end of the buffer.
+ (merge 5781a9a270 dt/xgethostname-nul-termination later to maint).
+
+ * A recent update broke "git add -p ../foo" from a subdirectory.
+
+ * While handy, "git_path()" is a dangerous function to use as a
+ callsite that uses it safely one day can be broken by changes
+ to other code that calls it. Reduction of its use continues.
+ (merge 16d2676c9e jk/war-on-git-path later to maint).
+
+ * The split-index code configuration code used an unsafe git_path()
+ function without copying its result out.
+
+ * Many stale HTTP(s) links have been updated in our documentation.
+ (merge 613416f0be jk/update-links-in-docs later to maint).
+
* Other minor doc, test and build updates and code cleanups.
