+Git 2.13 Release Notes
+======================
+
+Backward compatibility notes.
+
+ * Use of an empty string as a pathspec element that is used for
+ 'everything matches' is still warned and Git asks users to use a
+ more explicit '.' for that instead. The hope is that existing
+ users will not mind this change, and eventually the warning can be
+ turned into a hard error, upgrading the deprecation into removal of
+ this (mis)feature. That is not scheduled to happen in the upcoming
+ release (yet).
+
+ * The historical argument order "git merge <msg> HEAD <commit>..."
+ has been deprecated for quite some time, and is now removed.
+
+ * The default location "~/.git-credential-cache/socket" for the
+ socket used to communicate with the credential-cache daemon has
+ been moved to "~/.cache/git/credential/socket".
+
+ * 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").
+ We've tried hard to locate such cases and fixed them, but there
+ might still be cases that need to be addressed--bug reports are
+ greatly appreciated.
+
+
+Updates since v2.12
+-------------------
+
+UI, Workflows & Features
+
+ * "git describe" and "git name-rev" have been taught to take more
+ than one refname patterns to restrict the set of refs to base their
+ naming output on, and also learned to take negative patterns to
+ name refs not to be used for naming via their "--exclude" option.
+
+ * Deletion of a branch "foo/bar" could remove .git/refs/heads/foo
+ once there no longer is any other branch whose name begins with
+ "foo/", but we didn't do so so far. Now we do.
+
+ * When "git merge" detects a path that is renamed in one history
+ while the other history deleted (or modified) it, it now reports
+ both paths to help the user understand what is going on in the two
+ histories being merged.
+
+ * The <url> part in "http.<url>.<variable>" configuration variable
+ can now be spelled with '*' that serves as wildcard.
+ E.g. "http.https://*.example.com.proxy" can be used to specify the
+ proxy used for https://a.example.com, https://b.example.com, etc.,
+ i.e. any host in the example.com domain.
+
+ * "git tag" did not leave useful message when adding a new entry to
+ reflog; this was left unnoticed for a long time because refs/tags/*
+ doesn't keep reflog by default.
+
+ * The "negative" pathspec feature was somewhat more cumbersome to use
+ than necessary in that its short-hand used "!" which needed to be
+ escaped from shells, and it required "exclude from what?" specified.
+
+ * The command line options for ssh invocation needs to be tweaked for
+ some implementations of SSH (e.g. PuTTY plink wants "-P <port>"
+ while OpenSSH wants "-p <port>" to specify port to connect to), and
+ the variant was guessed when GIT_SSH environment variable is used
+ to specify it. The logic to guess now applies to the command
+ specified by the newer GIT_SSH_COMMAND and also core.sshcommand
+ configuration variable, and comes with an escape hatch for users to
+ deal with misdetected cases.
+
+ * The "--git-path", "--git-common-dir", and "--shared-index-path"
+ options of "git rev-parse" did not produce usable output. They are
+ now updated to show the path to the correct file, relative to where
+ the caller is.
+
+ * "git diff -W" has been taught to handle the case where a new
+ function is added at the end of the file better.
+
+ * "git update-ref -d" and other operations to delete references did
+ not leave any entry in HEAD's reflog when the reference being
+ deleted was the current branch. This is not a problem in practice
+ because you do not want to delete the branch you are currently on,
+ but caused renaming of the current branch to something else not to
+ be logged in a useful way.
+
+ * "Cc:" on the trailer part does not have to conform to RFC strictly,
+ unlike in the e-mail header. "git send-email" has been updated to
+ ignore anything after '>' when picking addresses, to allow non-address
+ cruft like " # stable 4.4" after the address.
+
+ * When "git submodule init" decides that the submodule in the working
+ tree is its upstream, it now gives a warning as it is not a very
+ common setup.
+
+ * "git stash push" takes a pathspec so that the local changes can be
+ stashed away only partially.
+
+ * Documentation for "git ls-files" did not refer to core.quotePath.
+
+ * The experimental "split index" feature has gained a few
+ configuration variables to make it easier to use.
+
+ * From a working tree of a repository, a new option of "rev-parse"
+ lets you ask if the repository is used as a submodule of another
+ project, and where the root level of the working tree of that
+ project (i.e. your superproject) is.
+
+ * The pathspec mechanism learned to further limit the paths that
+ match the pattern to those that have specified attributes attached
+ via the gitattributes mechanism.
+
+ * Our source code has used the SHA1_HEADER cpp macro after "#include"
+ in the C code to switch among the SHA-1 implementations. Instead,
+ list the exact header file names and switch among implementations
+ using "#ifdef BLK_SHA1/#include "block-sha1/sha1.h"/.../#endif";
+ this helps some IDE tools.
+
+ * The start-up sequence of "git" needs to figure out some configured
+ settings before it finds and set itself up in the location of the
+ repository and was quite messy due to its "chicken-and-egg" nature.
+ The code has been restructured.
+
+ * The command line prompt (in contrib/) learned a new 'tag' style
+ that can be specified with GIT_PS1_DESCRIBE_STYLE, to describe a
+ detached HEAD with "git describe --tags".
+
+ * The configuration file learned a new "includeIf.<condition>.path"
+ that includes the contents of the given path only when the
+ condition holds. This allows you to say "include this work-related
+ bit only in the repositories under my ~/work/ directory".
+
+ * Recent update to "rebase -i" started showing a message that is not
+ a warning with "warning:" prefix by mistake. This has been fixed.
+
+ * Recently we started passing the "--push-options" through the
+ external remote helper interface; now the "smart HTTP" remote
+ helper understands what to do with the passed information.
+
+ * "git describe --dirty" dies when it cannot be determined if the
+ state in the working tree matches that of HEAD (e.g. broken
+ repository or broken submodule). The command learned a new option
+ "git describe --broken" to give "$name-broken" (where $name is the
+ description of HEAD) in such a case.
+
+ * "git checkout" is taught the "--recurse-submodules" option.
+
+ * Recent enhancement to "git stash push" command to support pathspec
+ to allow only a subset of working tree changes to be stashed away
+ was found to be too chatty and exposed the internal implementation
+ detail (e.g. when it uses reset to match the index to HEAD before
+ 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.
+
+ * The code to list branches in "git branch" has been consolidated
+ with the more generic ref-filter API.
+
+ * Resource usage while enumerating refs from alternate object store
+ has been optimized to help receiving end of "push" that hosts a
+ repository with many "forks".
+
+ * The gitattributes machinery is being taught to work better in a
+ multi-threaded environment.
+
+ * "git rebase -i" starts using the recently updated "sequencer" code.
+
+ * Code and design clean-up for the refs API.
+
+ * The preload-index code has been taught not to bother with the index
+ entries that are paths that are not checked out by "sparse checkout".
+
+ * Some warning() messages from "git clean" were updated to show the
+ errno from failed system calls.
+
+ * The "parse_config_key()" API function has been cleaned up.
+
+ * A test that creates a confusing branch whose name is HEAD has been
+ corrected not to do so.
+
+ * The code that parses header fields in the commit object has been
+ updated for (micro)performance and code hygiene.
+
+ * An helper function to make it easier to append the result from
+ real_path() to a strbuf has been added.
+
+ * Reduce authentication round-trip over HTTP when the server supports
+ just a single authentication method. This also improves the
+ behaviour when Git is misconfigured to enable http.emptyAuth
+ against a server that does not authenticate without a username
+ (i.e. not using Kerberos etc., which makes http.emptyAuth
+ pointless).
+
+ * Windows port wants to use OpenSSL's implementation of SHA-1
+ routines, so let them.
+
+ * The t/perf performance test suite was not prepared to test not so
+ old versions of Git, but now it covers versions of Git that are not
+ so ancient.
+
+ * Add 32-bit Linux variant to the set of platforms to be tested with
+ Travis CI.
+
+ * "git branch --list" takes the "--abbrev" and "--no-abbrev" options
+ to control the output of the object name in its "-v"(erbose)
+ output, but a recent update started ignoring them; fix it before
+ the breakage reaches to any released version.
+
+ * Picking two versions of Git and running tests to make sure the
+ older one and the newer one interoperate happily has now become
+ possible.
+
+ * "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
+ facility.
+
+ * The "debug" helper used in the test framework learned to run
+ a command under "gdb" interactively.
+
+ * The "detect attempt to create collisions" variant of SHA-1
+ implementation by Marc Stevens (CWI) and Dan Shumow (Microsoft)
+ has been integrated and made the default.
+
+ * The test framework learned to detect unterminated here documents.
+
+ * The name-hash used for detecting paths that are different only in
+ cases (which matter on case insensitive filesystems) has been
+ optimized to take advantage of multi-threading when it makes sense.
+
+ * 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.
+
+
+Fixes since v2.12
+-----------------
+
+Unless otherwise noted, all the fixes since v2.12 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git repack --depth=<n>" for a long time busted the specified depth
+ when reusing delta from existing packs. This has been corrected.
+
+ * The code to parse the command line "git grep <patterns>... <rev>
+ [[--] <pathspec>...]" has been cleaned up, and a handful of bugs
+ have been fixed (e.g. we used to check "--" if it is a rev).
+
+ * "git ls-remote" and "git archive --remote" are designed to work
+ without being in a directory under Git's control. However, recent
+ updates revealed that we randomly look into a directory called
+ .git/ without actually doing necessary set-up when working in a
+ repository. Stop doing so.
+
+ * "git show-branch" expected there were only very short branch names
+ in the repository and used a fixed-length buffer to hold them
+ without checking for overflow.
+
+ * A caller of tempfile API that uses stdio interface to write to
+ files may ignore errors while writing, which is detected when
+ tempfile is closed (with a call to ferror()). By that time, the
+ original errno that may have told us what went wrong is likely to
+ be long gone and was overwritten by an irrelevant value.
+ close_tempfile() now resets errno to EIO to make errno at least
+ predictable.
+
+ * "git remote rm X", when a branch has remote X configured as the
+ value of its branch.*.remote, tried to remove branch.*.remote and
+ branch.*.merge and failed if either is unset.
+
+ * A "gc.log" file left by a backgrounded "gc --auto" disables further
+ automatic gc; it has been taught to run at least once a day (by
+ default) by ignoring a stale "gc.log" file that is too old.
+
+ * The code to parse "git -c VAR=VAL cmd" and set configuration
+ variable for the duration of cmd had two small bugs, which have
+ been fixed.
+
+ * user.email that consists of only cruft chars should consistently
+ error out, but didn't.
+
+ * "git upload-pack", which is a counter-part of "git fetch", did not
+ report a request for a ref that was not advertised as invalid.
+ This is generally not a problem (because "git fetch" will stop
+ before making such a request), but is the right thing to do.
+
+ * A leak in a codepath to read from a packed object in (rare) cases
+ has been plugged.
+
+ * When a redirected http transport gets an error during the
+ redirected request, we ignored the error we got from the server,
+ and ended up giving a not-so-useful error message.
+
+ * The patch subcommand of "git add -i" was meant to have paths
+ selection prompt just like other subcommand, unlike "git add -p"
+ directly jumps to hunk selection. Recently, this was broken and
+ "add -i" lost the paths selection dialog, but it now has been
+ fixed.
+
+ * Git v2.12 was shipped with an embarrassing breakage where various
+ operations that verify paths given from the user stopped dying when
+ seeing an issue, and instead later triggering segfault.
+
+ * There is no need for Python only to give a few messages to the
+ standard error stream, but we somehow did.
+
+ * The code to parse "git log -L..." command line was buggy when there
+ are many ranges specified with -L; overrun of the allocated buffer
+ has been fixed.
+
+ * The command-line parsing of "git log -L" copied internal data
+ structures using incorrect size on ILP32 systems.
+
+ * "git diff --quiet" relies on the size field in diff_filespec to be
+ correctly populated, but diff_populate_filespec() helper function
+ made an incorrect short-cut when asked only to populate the size
+ field for paths that need to go through convert_to_git() (e.g. CRLF
+ conversion).
+
+ * A few tests were run conditionally under (rare) conditions where
+ they cannot be run (like running cvs tests under 'root' account).
+
+ * "git branch @" created refs/heads/@ as a branch, and in general the
+ code that handled @{-1} and @{upstream} was a bit too loose in
+ disambiguating.
+
+ * "git fetch" that requests a commit by object name, when the other
+ side does not allow such an request, failed without much
+ explanation.
+
+ * "git filter-branch --prune-empty" drops a single-parent commit that
+ becomes a no-op, but did not drop a root commit whose tree is empty.
+
+ * Recent versions of Git treats http alternates (used in dumb http
+ transport) just like HTTP redirects and requires the client to
+ enable following it, due to security concerns. But we forgot to
+ give a warning when we decide not to honor the alternates.
+
+ * "git push" had a handful of codepaths that could lead to a deadlock
+ when unexpected error happened, which has been fixed.
+
+ * "Dumb http" transport used to misparse a nonsense http-alternates
+ response, which has been fixed.
+
+ * "git add -p <pathspec>" unnecessarily expanded the pathspec to a
+ list of individual files that matches the pathspec by running "git
+ ls-files <pathspec>", before feeding it to "git diff-index" to see
+ which paths have changes, because historically the pathspec
+ language supported by "diff-index" was weaker. These days they are
+ equivalent and there is no reason to internally expand it. This
+ helps both performance and avoids command line argument limit on
+ some platforms.
+ (merge 7288e12cce jk/add-i-use-pathspecs later to maint).
+
+ * "git status --porcelain" is supposed to give a stable output, but a
+ few strings were left as translatable by mistake.
+
+ * "git revert -m 0 $merge_commit" complained that reverting a merge
+ needs to say relative to which parent the reversion needs to
+ happen, as if "-m 0" weren't given. The correct diagnosis is that
+ "-m 0" does not refer to the first parent ("-m 1" does). This has
+ been fixed.
+
+ * Code to read submodule.<name>.ignore config did not state the
+ variable name correctly when giving an error message diagnosing
+ misconfiguration.
+
+ * Fix for NO_PTHREADS build.
+
+ * Fix for potential segv introduced in v2.11.0 and later (also
+ v2.10.2) to "git log --pickaxe-regex -S".
+
+ * A few unterminated here documents in tests were fixed, which in
+ turn revealed incorrect expectations the tests make. These tests
+ have been updated.
+
+ * 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).
+
+ * "git-shell" rejects a request to serve a repository whose name
+ begins with a dash, which makes it no longer possible to get it
+ confused into spawning service programs like "git-upload-pack" with
+ an option like "--help", which in turn would spawn an interactive
+ pager, instead of working with the repository user asked to access
+ (i.e. the one whose name is "--help").
+
+ * Other minor doc, test and build updates and code cleanups.

+Git v2.13.1 Release Notes
+=========================
+
+Fixes since v2.13
+-----------------
+
+ * The Web interface to gmane news archive is long gone, even though
+ the articles are still accessible via NTTP. Replace the links with
+ ones to public-inbox.org. Because their message identification is
+ based on the actual message-id, it is likely that it will be easier
+ to migrate away from it if/when necessary.
+
+ * Update tests to pass under GETTEXT_POISON (a mechanism to ensure
+ that output strings that should not be translated are not
+ translated by mistake), and tell TravisCI to run them.
+
+ * Setting "log.decorate=false" in the configuration file did not take
+ effect in v2.13, which has been corrected.
+
+ * An earlier update to test 7400 needed to be skipped on CYGWIN.
+
+ * Git sometimes gives an advice in a rhetorical question that does
+ not require an answer, which can confuse new users and non native
+ speakers. Attempt to rephrase them.
+
+ * "git read-tree -m" (no tree-ish) gave a nonsense suggestion "use
+ --empty if you want to clear the index". With "-m", such a request
+ will still fail anyway, as you'd need to name at least one tree-ish
+ to be merged.
+
+ * The codepath in "git am" that is used when running "git rebase"
+ leaked memory held for the log message of the commits being rebased.
+
+ * "pack-objects" can stream a slice of an existing packfile out when
+ the pack bitmap can tell that the reachable objects are all needed
+ in the output, without inspecting individual objects. This
+ strategy however would not work well when "--local" and other
+ options are in use, and need to be disabled.
+
+ * Clarify documentation for include.path and includeIf.<condition>.path
+ configuration variables.
+
+ * Tag objects, which are not reachable from any ref, that point at
+ missing objects were mishandled by "git gc" and friends (they
+ should silently be ignored instead)
+
+ * A few http:// links that are redirected to https:// in the
+ documentation have been updated to https:// links.
+
+ * Make sure our tests would pass when the sources are checked out
+ with "platform native" line ending convention by default on
+ Windows. Some "text" files out tests use and the test scripts
+ themselves that are meant to be run with /bin/sh, ought to be
+ checked out with eol=LF even on Windows.
+
+ * Fix memory leaks pointed out by Coverity (and people).
+
+ * The receive-pack program now makes sure that the push certificate
+ records the same set of push options used for pushing.
+
+ * "git cherry-pick" and other uses of the sequencer machinery
+ mishandled a trailer block whose last line is an incomplete line.
+ This has been fixed so that an additional sign-off etc. are added
+ after completing the existing incomplete line.
+
+ * The shell completion script (in contrib/) learned "git stash" has
+ a new "push" subcommand.
+
+ * Travis CI gained a task to format the documentation with both
+ AsciiDoc and AsciiDoctor.
+
+ * Update the C style recommendation for notes for translators, as
+ recent versions of gettext tools can work with our style of
+ multi-line comments.
+
+ * "git clone --config var=val" is a way to populate the
+ per-repository configuration file of the new repository, but it did
+ not work well when val is an empty string. This has been fixed.
+
+ * A few codepaths in "checkout" and "am" working on an unborn branch
+ tried to access an uninitialized piece of memory.
+
+ * "git for-each-ref --format=..." with %(HEAD) in the format used to
+ resolve the HEAD symref as many times as it had processed refs,
+ which was wasteful, and "git branch" shared the same problem.
+
+ * "git interpret-trailers", when used as GIT_EDITOR for "git commit
+ -v", looked for and appended to a trailer block at the very end,
+ i.e. at the end of the "diff" output. The command has been
+ corrected to pay attention to the cut-mark line "commit -v" adds to
+ the buffer---the real trailer block should appear just before it.
+
+ * A test allowed both "git push" and "git receive-pack" on the other
+ end write their traces into the same file. This is OK on platforms
+ that allows atomically appending to a file opened with O_APPEND,
+ but on other platforms led to a mangled output, causing
+ intermittent test failures. This has been fixed by disabling
+ traces from "receive-pack" in the test.
+
+ * "foo\bar\baz" in "git fetch foo\bar\baz", even though there is no
+ slashes in it, cannot be a nickname for a remote on Windows, as
+ that is likely to be a pathname on a local filesystem.
+
+ * The "collision detecting" SHA-1 implementation shipped with 2.13
+ was quite broken on some big-endian platforms and/or platforms that
+ do not like unaligned fetches. Update to the upstream code which
+ has already fixed these issues.
+
+ * "git am -h" triggered a BUG().
+
+ * The interaction of "url.*.insteadOf" and custom URL scheme's
+ whitelisting is now documented better.
+
+Also contains various documentation updates and code clean-ups.

+Git 2.14 Release Notes
+======================
+
+Backward compatibility notes.
+
+ * Use of an empty string as a pathspec element that is used for
+ 'everything matches' is still warned and Git asks users to use a
+ more explicit '.' for that instead. The hope is that existing
+ users will not mind this change, and eventually the warning can be
+ turned into a hard error, upgrading the deprecation into removal of
+ this (mis)feature. That is not scheduled to happen in the upcoming
+ release (yet).
+
+ * 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").
+ We've tried hard to locate such cases and fixed them, but there
+ might still be cases that need to be addressed--bug reports are
+ greatly appreciated.
+
+ * The experiment to improve the hunk-boundary selection of textual
+ diff output has finished, and the "indent heuristics" has now
+ become the default.
+
+
+Updates since v2.13
+-------------------
+
+UI, Workflows & Features
+
+ * The colors in which "git status --short --branch" showed the names
+ of the current branch and its remote-tracking branch are now
+ configurable.
+
+ * "git clone" learned the "--no-tags" option not to fetch all tags
+ initially, and also set up the tagopt not to follow any tags in
+ subsequent fetches.
+
+ * "git archive --format=zip" learned to use zip64 extension when
+ necessary to go beyond the 4GB limit.
+ (merge 867e40ff3a rs/large-zip later to maint).
+
+ * "git reset" learned "--recurse-submodules" option.
+
+ * "git diff --submodule=diff" now recurses into nested submodules.
+ (merge 5a5221427c jk/diff-submodule-diff-inline later to maint).
+
+ * "git repack" learned to accept the --threads=<n> option and pass it
+ to pack-objects.
+
+ * "git send-email" learned to run sendemail-validate hook to inspect
+ and reject a message before sending it out.
+ (merge 177409e589 jt/send-email-validate-hook later to maint).
+
+ * There is no good reason why "git fetch $there $sha1" should fail
+ when the $sha1 names an object at the tip of an advertised ref,
+ even when the other side hasn't enabled allowTipSHA1InWant.
+
+ * The recently introduced "[includeIf "gitdir:$dir"] path=..."
+ mechansim has further been taught to take symlinks into account.
+ The directory "$dir" specified in "gitdir:$dir" may be a symlink to
+ a real location, not something that $(getcwd) may return. In such
+ a case, a realpath of "$dir" is compared with the real path of the
+ current repository to determine if the contents from the named path
+ should be included.
+
+ * Make the "indent" heuristics the default in "diff" and diff.indentHeuristics
+ configuration variable an escape hatch for those who do no want it.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The default packed-git limit value has been raised on larger
+ platforms to save "git fetch" from a (recoverable) failure while
+ "gc" is running in parallel.
+
+ * Code to update the cache-tree has been tightened so that we won't
+ accidentally write out any 0{40} entry in the tree object.
+ (merge a96d3cc3f6 jk/no-null-sha1-in-cache-tree later to maint).
+
+ * Attempt to allow us notice "fishy" situation where we fail to
+ remove the temporary directory used during the test.
+
+ * Travis CI gained a task to format the documentation with both
+ AsciiDoc and AsciiDoctor.
+
+ * Some platforms have ulong that is smaller than time_t, and our
+ historical use of ulong for timestamp would mean they cannot
+ represent some timestamp that the platform allows. Invent a
+ separate and dedicated timestamp_t (so that we can distingiuish
+ timestamps and a vanilla ulongs, which along is already a good
+ move), and then declare uintmax_t is the type to be used as the
+ timestamp_t.
+
+ * We can trigger Windows auto-build tester (credits: Dscho &
+ Microsoft) from our existing Travis CI tester now.
+
+ * Conversion from uchar[20] to struct object_id continues.
+
+ * Simplify parse_pathspec() codepath and stop it from looking at the
+ default in-core index.
+ (merge 08de9151a8 bw/pathspec-sans-the-index later to maint).
+
+ * Add perf-test for wildmatch.
+ (merge 62ca75a6b9 ab/perf-wildmatch later to maint).
+
+ * Code from "conversion using external process" codepath has been
+ extracted to a separate sub-process.[ch] module.
+ (merge 4f2a2e9f0e bp/sub-process-convert-filter later to maint).
+
+ * When "git checkout", "git merge", etc. manipulates the in-core
+ index, various pieces of information in the index extensions are
+ discarded from the original state, as it is usually not the case
+ that they are kept up-to-date and in-sync with the operation on the
+ main index. The untracked cache extension is copied across these
+ operations now, which would speed up "git status" (as long as the
+ cache is properly invalidated).
+
+ * The internal implementation of "git grep" has seen some clean-up.
+ (merge 8df4c2953f ab/grep-preparatory-cleanup later to maint).
+
+ * Update the C style recommendation for notes for translators, as
+ recent versions of gettext tools can work with our style of
+ multi-line comments.
+
+ * The implementation of "ref" API around the "packed refs" have been
+ cleaned up, in preparation for further changes.
+
+ * The internal logic used in "git blame" has been libified to make it
+ easier to use by cgit.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.13
+-----------------
+
+Unless otherwise noted, all the fixes since v2.13 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git gc" did not interact well with "git worktree"-managed
+ per-worktree refs.
+
+ * "git cherry-pick" and other uses of the sequencer machinery
+ mishandled a trailer block whose last line is an incomplete line.
+ This has been fixed so that an additional sign-off etc. are added
+ after completing the existing incomplete line.
+
+ * The codepath in "git am" that is used when running "git rebase"
+ leaked memory held for the log message of the commits being rebased.
+
+ * "git clone --config var=val" is a way to populate the

+
+ * Tests have been updated to pass under GETTEXT_POISON (a mechanism
+ to ensure that output strings that should not be translated are
+ not translated by mistake), and TravisCI is told to run them.
+
+ * "git checkout --recurse-submodules" did not quite work with a
+ submodule that itself has submodules.
+ (merge 218c883783 sb/checkout-recurse-submodules later to maint).
+
+ * Plug some leaks and updates internal API used to implement the
+ split index feature to make it easier to avoid such a leak in the
+ future.
+ (merge de950c5773 nd/split-index-unshare later to maint).
+
+ * "pack-objects" can stream a slice of an existing packfile out when
+ the pack bitmap can tell that the reachable objects are all needed
+ in the output, without inspecting individual objects. This
+ strategy however would not work well when "--local" and other
+ options are in use, and need to be disabled.

+ to be merged.
+
+ * Make sure our tests would pass when the sources are checked out
+ with "platform native" line ending convention by default on
+ Windows. Some "text" files out tests use and the test scripts
+ themselves that are meant to be run with /bin/sh, ought to be
+ checked out with eol=LF even on Windows.
+
+ * Introduce the BUG() macro to improve die("BUG: ...").
+ (merge 3d7dd2d3b6 jk/bug-to-abort later to maint).
+
+ * Clarify documentation for include.path and includeIf.<condition>.path
+ configuration variables.
+
+ * Git sometimes gives an advice in a rhetorical question that does
+ not require an answer, which can confuse new users and non native
+ speakers. Attempt to rephrase them.
+
+ * A few http:// links that are redirected to https:// in the
+ documentation have been updated to https:// links.
+

+
+Conditional includes
+~~~~~~~~~~~~~~~~~~~~
+
+You can include a config file from another conditionally by setting a
+`includeIf.<condition>.path` variable to the name of the file to be
+included.
+
+The condition starts with a keyword followed by a colon and some data
+whose format and meaning depends on the keyword. Supported keywords
+are:
+
+`gitdir`::
+
+ The data that follows the keyword `gitdir:` is used as a glob
+ pattern. If the location of the .git directory matches the
+ pattern, the include condition is met.
++
+The .git location may be auto-discovered, or come from `$GIT_DIR`
+environment variable. If the repository is auto discovered via a .git
+file (e.g. from submodules, or a linked worktree), the .git location
+would be the final location where the .git directory is, not where the
+.git file is.
++
+The pattern can contain standard globbing wildcards and two additional
+ones, `**/` and `/**`, that can match multiple path components. Please
+refer to linkgit:gitignore[5] for details. For convenience:
+
+ * If the pattern starts with `~/`, `~` will be substituted with the
+ content of the environment variable `HOME`.
+
+ * If the pattern starts with `./`, it is replaced with the directory
+ containing the current config file.
+
+ * If the pattern does not start with either `~/`, `./` or `/`, `**/`
+ will be automatically prepended. For example, the pattern `foo/bar`
+ becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.
+
+ * If the pattern ends with `/`, `**` will be automatically added. For
+ example, the pattern `foo/` becomes `foo/**`. In other words, it
+ matches "foo" and everything inside, recursively.
+
+`gitdir/i`::
+ This is the same as `gitdir` except that matching is done
+ case-insensitively (e.g. on case-insensitive file sytems)
+
+A few more notes on matching via `gitdir` and `gitdir/i`:
+
+ * Symlinks in `$GIT_DIR` are not resolved before matching.
+
+ * Both the symlink & realpath versions of paths will be matched
+ outside of `$GIT_DIR`. E.g. if ~/git is a symlink to
+ /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git`
+ will match.
++
+This was not the case in the initial release of this feature in
+v2.13.0, which only matched the realpath version. Configuration that
+wants to be compatible with the initial release of this feature needs
+to either specify only the realpath version, or both versions.
+
+ * Note that "../" is not special and will match literally, which is
+ unlikely what you want.

"--no-force-with-lease" will cancel all the previous --force-with-lease on the

++
+A general note on safety: supplying this option without an expected
+value, i.e. as `--force-with-lease` or `--force-with-lease=<refname>`
+interacts very badly with anything that implicitly runs `git fetch` on
+the remote to be pushed to in the background, e.g. `git fetch origin`
+on your repository in a cronjob.
++
+The protection it offers over `--force` is ensuring that subsequent
+changes your work wasn't based on aren't clobbered, but this is
+trivially defeated if some background process is updating refs in the
+background. We don't have anything except the remote tracking info to
+go by as a heuristic for refs you're expected to have seen & are
+willing to clobber.
++
+If your editor or some other system is running `git fetch` in the
+background for you a way to mitigate this is to simply set up another
+remote:
++
+ git remote add origin-push $(git config remote.origin.url)
+ git fetch origin-push
++
+Now when the background process runs `git fetch origin` the references
+on `origin-push` won't be updated, and thus commands like:
++
+ git push --force-with-lease origin-push
++
+Will fail unless you manually run `git fetch origin-push`. This method
+is of course entirely defeated by something that runs `git fetch
+--all`, in that case you'd need to either disable it or do something
+more tedious like:
++
+ git fetch # update 'master' from remote
+ git tag base master # mark our base point
+ git rebase -i master # rewrite some commits
+ git push --force-with-lease=master:base master:master
++
+I.e. create a `base` tag for versions of the upstream code that you've
+seen and are willing to overwrite, then rewrite history, and finally
+force push changes to `master` if the remote version is still at
+`base`, regardless of what your local `remotes/origin/master` has been
+updated to in the background.

+When `receive-pack` takes in objects, they are placed into a temporary

+has completed. If the push fails before then, the temporary directory is

+This has a few user-visible effects and caveats:

+ challenging.
+
+ 2. Any objects created by the `pre-receive` hook will be created in
+ the quarantine directory (and migrated only if it succeeds).
+
+ 3. The `pre-receive` hook MUST NOT update any refs to point to
+ quarantined objects. Other programs accessing the repository will
+ not be able to see the objects (and if the pre-receive hook fails,
+ those refs would become corrupted). For safety, any ref updates

+Split index
+-----------
+
+This mode is designed for repositories with very large indexes, and
+aims at reducing the time it takes to repeatedly write these indexes.
+
+In this mode, the index is split into two files, $GIT_DIR/index and
+$GIT_DIR/sharedindex.<SHA-1>. Changes are accumulated in
+$GIT_DIR/index, the split index, while the shared index file contains
+all index entries and stays unchanged.
+
+All changes in the split index are pushed back to the shared index
+file when the number of entries in the split index reaches a level
+specified by the splitIndex.maxPercentChange config variable (see
+linkgit:git-config[1]).
+
+Each time a new shared index file is created, the old shared index
+files are deleted if their modification time is older than what is
+specified by the splitIndex.sharedIndexExpire config variable (see
+linkgit:git-config[1]).
+
+To avoid deleting a shared index file that is still used, its
+modification time is updated to the current time everytime a new split
+index based on the shared index file is either created or read from.

+sub-process API
+===============
+
+The sub-process API makes it possible to run background sub-processes
+for the entire lifetime of a Git invocation. If Git needs to communicate
+with an external process multiple times, then this can reduces the process
+invocation overhead. Git and the sub-process communicate through stdin and
+stdout.
+
+The sub-processes are kept in a hashmap by command name and looked up
+via the subprocess_find_entry function. If an existing instance can not
+be found then a new process should be created and started. When the
+parent git command terminates, all sub-processes are also terminated.
+
+This API is based on the run-command API.
