+Git 2.22 Release Notes
+======================
+
+Updates since v2.21
+-------------------
+
+Backward compatibility note
+
+ * The filter specification "--filter=sparse:path=<path>" used to
+ create a lazy/partial clone has been removed. Using a blob that is
+ part of the project as sparse specification is still supported with
+ the "--filter=sparse:oid=<blob>" option.
+
+UI, Workflows & Features
+
+ * "git checkout --no-overlay" can be used to trigger a new mode of
+ checking out paths out of the tree-ish, that allows paths that
+ match the pathspec that are in the current index and working tree
+ and are not in the tree-ish.
+
+ * The %(trailers) formatter in "git log --format=..." now allows to
+ optionally pick trailers selectively by keyword, show only values,
+ etc.
+
+ * Four new configuration variables {author,committer}.{name,email}
+ have been introduced to override user.{name,email} in more specific
+ cases.
+
+ * Command-line completion (in contrib/) learned to tab-complete the
+ "git submodule absorbgitdirs" subcommand.
+
+ * "git branch" learned a new subcommand "--show-current".
+
+ * Output from "diff --cc" did not show the original paths when the
+ merge involved renames. A new option adds the paths in the
+ original trees to the output.
+
+ * The command line completion (in contrib/) has been taught to
+ complete more subcommand parameters.
+
+ * The final report from "git bisect" used to show the suspected
+ culprit using a raw "diff-tree", with which there is no output for
+ a merge commit. This has been updated to use a more modern and
+ human readable output that still is concise enough.
+
+ * "git rebase --rebase-merges" replaces its old "--preserve-merges"
+ option; the latter is now marked as deprecated.
+
+ * Error message given while cloning with --recurse-submodules has
+ been updated.
+
+ * The completion helper code now pays attention to repository-local
+ configuration (when available), which allows --list-cmds to honour
+ a repository specific setting of completion.commands, for example.
+
+ * "git mergetool" learned to offer Sublime Merge (smerge) as one of
+ its backends.
+
+ * A new hook "post-index-change" is called when the on-disk index
+ file changes, which can help e.g. a virtualized working tree
+ implementation.
+
+ * "git difftool" can now run outside a repository.
+
+ * "git checkout -m <other>" was about carrying the differences
+ between HEAD and the working-tree files forward while checking out
+ another branch, and ignored the differences between HEAD and the
+ index. The command has been taught to abort when the index and the
+ HEAD are different.
+
+ * A progress indicator has been added to the "index-pack" step, which
+ often makes users wait for completion during "git clone".
+
+ * "git submodule" learns "set-branch" subcommand that allows the
+ submodule.*.branch settings to be modified.
+
+ * "git merge-recursive" backend recently learned a new heuristics to
+ infer file movement based on how other files in the same directory
+ moved. As this is inherently less robust heuristics than the one
+ based on the content similarity of the file itself (rather than
+ based on what its neighbours are doing), it sometimes gives an
+ outcome unexpected by the end users. This has been toned down to
+ leave the renamed paths in higher/conflicted stages in the index so
+ that the user can examine and confirm the result.
+
+ * "git tag" learned to give an advice suggesting it might be a
+ mistake when creating an annotated or signed tag that points at
+ another tag.
+
+ * The "git pack-objects" command learned to report the number of
+ objects it packed via the trace2 mechanism.
+
+ * The list of conflicted paths shown in the editor while concluding a
+ conflicted merge was shown above the scissors line when the
+ clean-up mode is set to "scissors", even though it was commented
+ out just like the list of updated paths and other information to
+ help the user explain the merge better.
+
+ * The trace2 tracing facility learned to auto-generate a filename
+ when told to log to a directory.
+
+ * "git clone" learned a new --server-option option when talking over
+ the protocol version 2.
+
+ * The connectivity bitmaps are created by default in bare
+ repositories now; also the pathname hash-cache is created by
+ default to avoid making crappy deltas when repacking.
+
+ * "git branch new A...B" and "git checkout -b new A...B" have been
+ taught that in their contexts, the notation A...B means "the merge
+ base between these two commits", just like "git checkout A...B"
+ detaches HEAD at that commit.
+
+ * Update "git difftool" and "git mergetool" so that the combinations
+ of {diff,merge}.{tool,guitool} configuration variables serve as
+ fallback settings of each other in a sensible order.
+
+ * The "--dir-diff" mode of "git difftool" is not useful in "--no-index"
+ mode; they are now explicitly marked as mutually incompatible.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The diff machinery, one of the oldest parts of the system, which
+ long predates the parse-options API, uses fairly long and complex
+ handcrafted option parser. This is being rewritten to use the
+ parse-options API.
+
+ * The implementation of pack-redundant has been updated for
+ performance in a repository with many packfiles.
+
+ * A more structured way to obtain execution trace has been added.
+
+ * "git prune" has been taught to take advantage of reachability
+ bitmap when able.
+
+ * The command line parser of "git commit-tree" has been rewritten to
+ use the parse-options API.
+
+ * Suggest GitGitGadget instead of submitGit as a way to submit
+ patches based on GitHub PR to us.
+
+ * The test framework has been updated to help developers by making it
+ easier to run most of the tests under different versions of
+ over-the-wire protocols.
+
+ * Dev support update to make it easier to compare two formatted
+ results from our documentation.
+
+ * The scripted "git rebase" implementation has been retired.
+
+ * "git multi-pack-index verify" did not scale well with the number of
+ packfiles, which is being improved.
+
+ * "git stash" has been rewritten in C.
+
+ * The "check-docs" Makefile target to support developers has been
+ updated.
+
+ * The tests have been updated not to rely on the abbreviated option
+ names the parse-options API offers, to protect us from an
+ abbreviated form of an option that used to be unique within the
+ command getting non-unique when a new option that share the same
+ prefix is added.
+
+ * The scripted version of "git rebase -i" wrote and rewrote the todo
+ list many times during a single step of its operation, and the
+ recent C-rewrite made a faithful conversion of the logic to C. The
+ implementation has been updated to carry necessary information
+ around in-core to avoid rewriting the same file over and over
+ unnecessarily.
+
+ * Test framework update to more robustly clean up leftover files and
+ processes after tests are done.
+
+ * Conversion from unsigned char[20] to struct object_id continues.
+
+ * While running "git diff" in a lazy clone, we can upfront know which
+ missing blobs we will need, instead of waiting for the on-demand
+ machinery to discover them one by one. The code learned to aim to
+ achieve better performance by batching the request for these
+ promised blobs.
+
+ * During an initial "git clone --depth=..." partial clone, it is
+ pointless to spend cycles for a large portion of the connectivity
+ check that enumerates and skips promisor objects (which by
+ definition is all objects fetched from the other side). This has
+ been optimized out.
+
+ * Mechanically and systematically drop "extern" from function
+ declaration.
+
+ * The script to aggregate perf result unconditionally depended on
+ libjson-perl even though it did not have to, which has been
+ corrected.
+
+ * The internal implementation of "git rebase -i" has been updated to
+ avoid forking a separate "rebase--interactive" process.
+
+ * Allow DEP and ASLR for Windows build to for security hardening.
+
+ * Performance test framework has been broken and measured the version
+ of Git that happens to be on $PATH, not the specified one to
+ measure, for a while, which has been corrected.
+
+ * Optionally "make coccicheck" can feed multiple source files to
+ spatch, gaining performance while spending more memory.
+
+ * Attempt to use an abbreviated option in "git clone --recurs" is
+ responded by a request to disambiguate between --recursive and
+ --recurse-submodules, which is bad because these two are synonyms.
+ The parse-options API has been extended to define such synonyms
+ more easily and not produce an unnecessary failure.
+
+ * A pair of private functions in http.c that had names similar to
+ fread/fwrite did not return the number of elements, which was found
+ to be confusing.
+
+ * Update collision-detecting SHA-1 code to build properly on HP-UX.
+
+
+Fixes since v2.21
+-----------------
+
+ * "git prune-packed" did not notice and complain against excess
+ arguments given from the command line, which now it does.
+ (merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).
+
+ * Split-index fix.
+ (merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).
+
+ * "git diff --no-index" may still want to access Git goodies like
+ --ext-diff and --textconv, but so far these have been ignored,
+ which has been corrected.
+ (merge 287ab28bfa jk/diff-no-index-initialize later to maint).
+
+ * Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
+ a bug in the latter (lack of authentication retry) and generally
+ improves the code base.
+ (merge a97d00799a jt/http-auth-proto-v2-fix later to maint).
+
+ * The include file compat/bswap.h has been updated so that it is safe
+ to (accidentally) include it more than once.
+ (merge 33aa579a55 jk/guard-bswap-header later to maint).
+
+ * The set of header files used by "make hdr-check" unconditionally
+ included sha256/gcrypt.h, even when it is not used, causing the
+ make target to fail. We now skip it when GCRYPT_SHA256 is not in
+ use.
+ (merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
+
+ * The Makefile uses 'find' utility to enumerate all the *.h header
+ files, which is expensive on platforms with slow filesystems; it
+ now optionally uses "ls-files" if working within a repository,
+ which is a trick similar to how all sources are enumerated to run
+ ETAGS on.
+ (merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).
+
+ * "git rebase" that was reimplemented in C did not set ORIG_HEAD
+ correctly, which has been corrected.
+ (merge cbd29ead92 js/rebase-orig-head-fix later to maint).
+
+ * Dev support.
+ (merge f545737144 js/stress-test-ui-tweak later to maint).
+
+ * CFLAGS now can be tweaked when invoking Make while using
+ DEVELOPER=YesPlease; this did not work well before.
+ (merge 6d5d4b4e93 ab/makefile-help-devs-more later to maint).
+
+ * "git fsck --connectivity-only" omits computation necessary to sift
+ the objects that are not reachable from any of the refs into
+ unreachable and dangling. This is now enabled when dangling
+ objects are requested (which is done by default, but can be
+ overridden with the "--no-dangling" option).
+ (merge 8d8c2a5aef jk/fsck-doc later to maint).
+
+ * On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
+ the upload-pack that runs on the other end that hangs up after
+ detecting an error could cause "git fetch" to die with a signal,
+ which led to a flaky test. "git fetch" now ignores SIGPIPE during
+ the network portion of its operation (this is not a problem as we
+ check the return status from our write(2)s).
+ (merge 143588949c jk/no-sigpipe-during-network-transport later to maint).
+
+ * A recent update broke "is this object available to us?" check for
+ well-known objects like an empty tree (which should yield "yes",
+ even when there is no on-disk object for an empty tree), which has
+ been corrected.
+ (merge f06ab027ef jk/virtual-objects-do-exist later to maint).
+
+ * The setup code has been cleaned up to avoid leaks around the
+ repository_format structure.
+ (merge e8805af1c3 ma/clear-repository-format later to maint).
+
+ * "git config --type=color ..." is meant to replace "git config --get-color"
+ but there is a slight difference that wasn't documented, which is
+ now fixed.
+ (merge cd8e7593b9 jk/config-type-color-ends-with-lf later to maint).
+
+ * When the "clean" filter can reduce the size of a huge file in the
+ working tree down to a small "token" (a la Git LFS), there is no
+ point in allocating a huge scratch area upfront, but the buffer is
+ sized based on the original file size. The convert mechanism now
+ allocates very minimum and reallocates as it receives the output
+ from the clean filter process.
+ (merge 02156ab031 jh/resize-convert-scratch-buffer later to maint).
+
+ * "git rebase" uses the refs/rewritten/ hierarchy to store its
+ intermediate states, which inherently makes the hierarchy per
+ worktree, but it didn't quite work well.
+ (merge b9317d55a3 nd/rewritten-ref-is-per-worktree later to maint).
+
+ * "git log -L<from>,<to>:<path>" with "-s" did not suppress the patch
+ output as it should. This has been corrected.
+ (merge 05314efaea jk/line-log-with-patch later to maint).
+
+ * "git worktree add" used to do a "find an available name with stat
+ and then mkdir", which is race-prone. This has been fixed by using
+ mkdir and reacting to EEXIST in a loop.
+ (merge 7af01f2367 ms/worktree-add-atomic-mkdir later to maint).
+
+ * Build update for SHA-1 with collision detection.
+ (merge 07a20f569b jk/sha1dc later to maint).
+
+ * Build procedure has been fixed around use of asciidoctor instead of
+ asciidoc.
+ (merge 185f9a0ea0 ma/asciidoctor-fixes later to maint).
+
+ * remote-http transport did not anonymize URLs reported in its error
+ messages at places.
+ (merge c1284b21f2 js/anonymize-remote-curl-diag later to maint).
+
+ * Error messages given from the http transport have been updated so
+ that they can be localized.
+ (merge ed8b4132c8 js/remote-curl-i18n later to maint).
+
+ * "git init" forgot to read platform-specific repository
+ configuration, which made Windows port to ignore settings of
+ core.hidedotfiles, for example.
+
+ * A corner-case object name ambiguity while the sequencer machinery
+ is working (e.g. "rebase -i -x") has been fixed.
+
+ * "git format-patch" did not diagnose an error while opening the
+ output file for the cover-letter, which has been corrected.
+ (merge 2fe95f494c jc/format-patch-error-check later to maint).
+
+ * "git checkout -f <branch>" while the index has an unmerged path
+ incorrectly left some paths in an unmerged state, which has been
+ corrected.
+
+ * A corner case bug in the refs API has been corrected.
+ (merge d3322eb28b jk/refs-double-abort later to maint).
+
+ * Unicode update.
+ (merge 584b62c37b bb/unicode-12 later to maint).
+
+ * dumb-http walker has been updated to share more error recovery
+ strategy with the normal codepath.
+
+ * A buglet in configuration parser has been fixed.
+ (merge 19e7fdaa58 nd/include-if-wildmatch later to maint).
+
+ * The documentation for "git read-tree --reset -u" has been updated.
+ (merge b5a0bd694c nd/read-tree-reset-doc later to maint).
+
+ * Code clean-up around a much-less-important-than-it-used-to-be
+ update_server_info() function.
+ (merge b3223761c8 jk/server-info-rabbit-hole later to maint).
+
+ * The message given when "git commit -a <paths>" errors out has been
+ updated.
+ (merge 5a1dbd48bc nd/commit-a-with-paths-msg-update later to maint).
+
+ * "git cherry-pick --options A..B", after giving control back to the
+ user to ask help resolving a conflicted step, did not honor the
+ options it originally received, which has been corrected.
+
+ * Various glitches in "git gc" around reflog handling have been fixed.
+
+ * The code to read from commit-graph file has been cleanup with more
+ careful error checking before using data read from it.
+
+ * Performance fix around "git fetch" that grabs many refs.
+ (merge b764300912 jt/fetch-pack-wanted-refs-optim later to maint).
+
+ * Protocol v2 support in "git fetch-pack" of shallow clones has been
+ corrected.
+
+ * Performance fix around "git blame", especially in a linear history
+ (which is the norm we should optimize for).
+ (merge f892014943 dk/blame-keep-origin-blob later to maint).
+
+ * Performance fix for "rev-list --parents -- pathspec".
+ (merge 8320b1dbe7 jk/revision-rewritten-parents-in-prio-queue later to maint).
+
+ * Updating the display with progress message has been cleaned up to
+ deal better with overlong messages.
+ (merge 545dc345eb sg/overlong-progress-fix later to maint).
+
+ * "git blame -- path" in a non-bare repository starts blaming from
+ the working tree, and the same command in a bare repository errors
+ out because there is no working tree by definition. The command
+ has been taught to instead start blaming from the commit at HEAD,
+ which is more useful.
+ (merge a544fb08f8 sg/blame-in-bare-start-at-head later to maint).
+
+ * An underallocation in the code to read the untracked cache
+ extension has been corrected.
+ (merge 3a7b45a623 js/untracked-cache-allocfix later to maint).
+
+ * The code is updated to check the result of memory allocation before
+ it is used in more places, by using xmalloc and/or xcalloc calls.
+ (merge 999b951b28 jk/xmalloc later to maint).
+
+ * The GETTEXT_POISON test option has been quite broken ever since it
+ was made runtime-tunable, which has been fixed.
+ (merge f88b9cb603 jc/gettext-test-fix later to maint).
+
+ * Test fix on APFS that is incapable of store paths in Latin-1.
+ (merge 3889149619 js/iso8895-test-on-apfs later to maint).
+
+ * "git submodule foreach <command> --quiet" did not pass the option
+ down correctly, which has been corrected.
+ (merge a282f5a906 nd/submodule-foreach-quiet later to maint).
+
+ * "git send-email" has been taught to use quoted-printable when the
+ payload contains carriage-return. The use of the mechanism is in
+ line with the design originally added the codepath that chooses QP
+ when the payload has overly long lines.
+ (merge 74d76a1701 bc/send-email-qp-cr later to maint).
+
+ * The recently added feature to add addresses that are on
+ anything-by: trailers in 'git send-email' was found to be way too
+ eager and considered nonsense strings as if they can be legitimate
+ beginning of *-by: trailer. This has been tightened.
+
+ * Builds with gettext broke on recent macOS w/ Homebrew, which
+ seems to have stopped including from /usr/local/include; this
+ has been corrected.
+ (merge 92a1377a2a js/macos-gettext-build later to maint).
+
+ * Running "git add" on a repository created inside the current
+ repository is an explicit indication that the user wants to add it
+ as a submodule, but when the HEAD of the inner repository is on an
+ unborn branch, it cannot be added as a submodule. Worse, the files
+ in its working tree can be added as if they are a part of the outer
+ repository, which is not what the user wants. These problems are
+ being addressed.
+ (merge f937bc2f86 km/empty-repo-is-still-a-repo later to maint).
+
+ * "git cherry-pick" run with the "-x" or the "--signoff" option used
+ to (and more importantly, ought to) clean up the commit log message
+ with the --cleanup=space option by default, but this has been
+ broken since late 2017. This has been fixed.
+
+ * When given a tag that points at a commit-ish, "git replace --graft"
+ failed to peel the tag before writing a replace ref, which did not
+ make sense because the old graft mechanism the feature wants to
+ mimic only allowed to replace one commit object with another.
+ This has been fixed.
+ (merge ee521ec4cb cc/replace-graft-peel-tags later to maint).
+
+ * Code tightening against a "wrong" object appearing where an object
+ of a different type is expected, instead of blindly assuming that
+ the connection between objects are correctly made.
+ (merge 97dd512af7 tb/unexpected later to maint).
+
+ * An earlier update for MinGW and Cygwin accidentally broke MSVC build,
+ which has been fixed.
+ (merge 22c3634c0f ss/msvc-path-utils-fix later to maint).
+
+ * %(push:track) token used in the --format option to "git
+ for-each-ref" and friends was not showing the right branch, which
+ has been fixed.
+ (merge c646d0934e dr/ref-filter-push-track-fix later to maint).
+
+ * "make check-docs", "git help -a", etc. did not account for cases
+ where a particular build may deliberately omit some subcommands,
+ which has been corrected.
+
+ * The logic to tell if a Git repository has a working tree protects
+ "git branch -D" from removing the branch that is currently checked
+ out by mistake. The implementation of this logic was broken for
+ repositories with unusual name, which unfortunately is the norm for
+ submodules these days. This has been fixed.
+ (merge f3534c98e4 jt/submodule-repo-is-with-worktree later to maint).
+
+ * AIX shared the same build issues with other BSDs around fileno(fp),
+ which has been corrected.
+ (merge ee662bf5c6 cc/aix-has-fileno-as-a-macro later to maint).
+
+ * The autoconf generated configure script failed to use the right
+ gettext() implementations from -libintl by ignoring useless stub
+ implementations shipped in some C library, which has been
+ corrected.
+ (merge b71e56a683 vk/autoconf-gettext later to maint).
+
+ * Fix index-pack perf test so that the repeated invocations always
+ run in an empty repository, which emulates the initial clone
+ situation better.
+ (merge 775c71e16d jk/p5302-avoid-collision-check-cost later to maint).
+
+ * A "ls-files" that emulates "find" to enumerate files in the working
+ tree resulted in duplicated Makefile rules that caused the build to
+ issue an unnecessary warning during a trial build after merge
+ conflicts are resolved in working tree *.h files but before the
+ resolved results are added to the index. This has been corrected.
+
+ * "git cherry-pick" (and "revert" that shares the same runtime engine)
+ that deals with multiple commits got confused when the final step
+ gets stopped with a conflict and the user concluded the sequence
+ with "git commit". Attempt to fix it by cleaning up the state
+ files used by these commands in such a situation.
+ (merge 4a72486de9 pw/clean-sequencer-state-upon-final-commit later to maint).
+
+ * On a filesystem like HFS+, the names of the refs stored as filesystem
+ entities may become different from what the end-user expects, just
+ like files in the working tree get "renamed". Work around the
+ mismatch by paying attention to the core.precomposeUnicode
+ configuration.
+ (merge 8e712ef6fc en/unicode-in-refnames later to maint).
+
+ * The code to generate the multi-pack idx file was not prepared to
+ see too many packfiles and ran out of open file descriptor, which
+ has been corrected.
+
+ * To run tests for Git SVN, our scripts for CI used to install the
+ git-svn package (in the hope that it would bring in the right
+ dependencies). This has been updated to install the more direct
+ dependency, namely, libsvn-perl.
+ (merge db864306cf sg/ci-libsvn-perl later to maint).
+
+ * "git cvsexportcommit" running on msys did not expect cvsnt showed
+ "cvs status" output with CRLF line endings.
+
+ * The fsmonitor interface got out of sync after the in-core index
+ file gets discarded, which has been corrected.
+ (merge 398a3b0899 js/fsmonitor-refresh-after-discarding-index later to maint).
+
+ * "git status" did not know that the "label" instruction in the
+ todo-list "rebase -i -r" uses should not be shown as a hex object
+ name.
+
+ * A prerequisite check in the test suite to see if a working jgit is
+ available was made more robust.
+ (merge abd0f28983 tz/test-lib-check-working-jgit later to maint).
+
+ * The codepath to parse :<path> that obtains the object name for an
+ indexed object has been made more robust.
+
+ * Code cleanup, docfix, build fix, etc.
+ (merge 11f470aee7 jc/test-yes-doc later to maint).
+ (merge 90503a240b js/doc-symref-in-proto-v1 later to maint).
+ (merge 5c326d1252 jk/unused-params later to maint).

+Git 2.22.1 Release Notes
+========================
+
+Fixes since v2.22
+-----------------
+
+ * A relative pathname given to "git init --template=<path> <repo>"
+ ought to be relative to the directory "git init" gets invoked in,
+ but it instead was made relative to the repository, which has been
+ corrected.
+
+ * "git worktree add" used to fail when another worktree connected to
+ the same repository was corrupt, which has been corrected.
+
+ * The ownership rule for the file descriptor to fast-import remote
+ backend was mixed up, leading to unrelated file descriptor getting
+ closed, which has been fixed.
+
+ * "git update-server-info" used to leave stale packfiles in its
+ output, which has been corrected.
+
+ * The server side support for "git fetch" used to show incorrect
+ value for the HEAD symbolic ref when the namespace feature is in
+ use, which has been corrected.
+
+ * "git am -i --resolved" segfaulted after trying to see a commit as
+ if it were a tree, which has been corrected.
+
+ * "git bundle verify" needs to see if prerequisite objects exist in
+ the receiving repository, but the command did not check if we are
+ in a repository upfront, which has been corrected.
+
+ * "git merge --squash" is designed to update the working tree and the
+ index without creating the commit, and this cannot be countermanded
+ by adding the "--commit" option; the command now refuses to work
+ when both options are given.
+
+ * The data collected by fsmonitor was not properly written back to
+ the on-disk index file, breaking t7519 tests occasionally, which
+ has been corrected.
+
+ * Update to Unicode 12.1 width table.
+
+ * The command line to invoke a "git cat-file" command from inside
+ "git p4" was not properly quoted to protect a caret and running a
+ broken command on Windows, which has been corrected.
+
+ * "git request-pull" learned to warn when the ref we ask them to pull
+ from in the local repository and in the published repository are
+ different.
+
+ * When creating a partial clone, the object filtering criteria is
+ recorded for the origin of the clone, but this incorrectly used a
+ hardcoded name "origin" to name that remote; it has been corrected
+ to honor the "--origin <name>" option.
+
+ * "git fetch" into a lazy clone forgot to fetch base objects that are
+ necessary to complete delta in a thin packfile, which has been
+ corrected.
+
+ * The filter_data used in the list-objects-filter (which manages a
+ lazily sparse clone repository) did not use the dynamic array API
+ correctly---'nr' is supposed to point at one past the last element
+ of the array in use. This has been corrected.
+
+ * The description about slashes in gitignore patterns (used to
+ indicate things like "anchored to this level only" and "only
+ matches directories") has been revamped.
+
+ * The URL decoding code has been updated to avoid going past the end
+ of the string while parsing %-<hex>-<hex> sequence.
+
+ * The list of for-each like macros used by clang-format has been
+ updated.
+
+ * "git push --atomic" that goes over the transport-helper (namely,
+ the smart http transport) failed to prevent refs to be pushed when
+ it can locally tell that one of the ref update will fail without
+ having to consult the other end, which has been corrected.
+
+ * "git clean" silently skipped a path when it cannot lstat() it; now
+ it gives a warning.
+
+ * A codepath that reads from GPG for signed object verification read
+ past the end of allocated buffer, which has been fixed.
+
+ * "git rm" to resolve a conflicted path leaked an internal message
+ "needs merge" before actually removing the path, which was
+ confusing. This has been corrected.
+
+ * The "git clone" documentation refers to command line options in its
+ description in the short form; they have been replaced with long
+ forms to make them more recognisable.
+
+ * The configuration variable rebase.rescheduleFailedExec should be
+ effective only while running an interactive rebase and should not
+ affect anything when running a non-interactive one, which was not
+ the case. This has been corrected.
+
+ * "git submodule foreach" did not protect command line options passed
+ to the command to be run in each submodule correctly, when the
+ "--recursive" option was in use.
+
+ * Use "Erase in Line" CSI sequence that is already used in the editor
+ support to clear cruft in the progress output.
+
+ * The codepath to compute delta islands used to spew progress output
+ without giving the callers any way to squelch it, which has been
+ fixed.
+
+ * The code to parse scaled numbers out of configuration files has
+ been made more robust and also easier to follow.
+
+ * An incorrect list of options was cached after command line
+ completion failed (e.g. trying to complete a command that requires
+ a repository outside one), which has been corrected.
+
+ * "git rebase --abort" used to leave refs/rewritten/ when concluding
+ "git rebase -r", which has been corrected.
+
+ * "git stash show 23" used to work, but no more after getting
+ rewritten in C; this regression has been corrected.
+
+ * "git interpret-trailers" always treated '#' as the comment
+ character, regardless of core.commentChar setting, which has been
+ corrected.
+
+ * Code clean-up to avoid signed integer overlaps during binary search.
+
+ * "git checkout -p" needs to selectively apply a patch in reverse,
+ which did not work well.
+
+ * The commit-graph file is now part of the "files that the runtime
+ may keep open file descriptors on, all of which would need to be
+ closed when done with the object store", and the file descriptor to
+ an existing commit-graph file now is closed before "gc" finalizes a
+ new instance to replace it.
+
+ * Code restructuring during 2.20 period broke fetching tags via
+ "import" based transports.
+
+ * We have been trying out a few language features outside c89; the
+ coding guidelines document did not talk about them and instead had
+ a blanket ban against them.
+
+ * The internal diff machinery can be made to read out of bounds while
+ looking for --funcion-context line in a corner case, which has been
+ corrected.
+
+Also contains various documentation updates, code clean-ups and minor fixups.

+Git 2.23 Release Notes
+======================
+
+Updates since v2.22
+-------------------
+
+Backward compatibility note
+
+ * The "--base" option of "format-patch" computed the patch-ids for
+ prerequisite patches in an unstable way, which has been updated to
+ compute in a way that is compatible with "git patch-id --stable".
+
+ * The "git log" command by default behaves as if the --mailmap option
+ was given.
+
+
+UI, Workflows & Features
+
+ * The "git fast-export/import" pair has been taught to handle commits
+ with log messages in encoding other than UTF-8 better.
+
+ * In recent versions of Git, per-worktree refs are exposed in
+ refs/worktrees/<wtname>/ hierarchy, which means that worktree names
+ must be a valid refname component. The code now sanitizes the names
+ given to worktrees, to make sure these refs are well-formed.
+
+ * "git merge" learned "--quit" option that cleans up the in-progress
+ merge while leaving the working tree and the index still in a mess.
+
+ * "git format-patch" learns a configuration to set the default for
+ its --notes=<ref> option.
+
+ * The code to show args with potential typo that cannot be
+ interpreted as a commit-ish has been improved.
+
+ * "git clone --recurse-submodules" learned to set up the submodules
+ to ignore commit object names recorded in the superproject gitlink
+ and instead use the commits that happen to be at the tip of the
+ remote-tracking branches from the get-go, by passing the new
+ "--remote-submodules" option.
+
+ * The pattern "git diff/grep" use to extract funcname and words
+ boundary for Matlab has been extend to cover Octave, which is more
+ or less equivalent.
+
+ * "git help git" was hard to discover (well, at least for some
+ people).
+
+ * The pattern "git diff/grep" use to extract funcname and words
+ boundary for Rust has been added.
+
+ * "git status" can be told a non-standard default value for the
+ "--[no-]ahead-behind" option with a new configuration variable
+ status.aheadBehind.
+
+ * "git fetch" and "git pull" reports when a fetch results in
+ non-fast-forward updates to let the user notice unusual situation.
+ The commands learned "--no-show-forced-updates" option to disable
+ this safety feature.
+
+ * Two new commands "git switch" and "git restore" are introduced to
+ split "checking out a branch to work on advancing its history" and
+ "checking out paths out of the index and/or a tree-ish to work on
+ advancing the current history" out of the single "git checkout"
+ command.
+
+ * "git branch --list" learned to always output the detached HEAD as
+ the first item (when the HEAD is detached, of course), regardless
+ of the locale.
+
+ * The conditional inclusion mechanism learned to base the choice on
+ the branch the HEAD currently is on.
+
+ * "git rev-list --objects" learned the "--no-object-names" option to
+ squelch the path to the object that is used as a grouping hint for
+ pack-objects.
+
+ * A new tag.gpgSign configuration variable turns "git tag -a" into
+ "git tag -s".
+
+ * "git multi-pack-index" learned expire and repack subcommands.
+
+ * "git blame" learned to "ignore" commits in the history, whose
+ effects (as well as their presence) get ignored.
+
+ * "git cherry-pick/revert" learned a new "--skip" action.
+
+ * The tips of refs from the alternate object store can be used as
+ starting point for reachability computation now.
+
+ * Extra blank lines in "git status" output have been reduced.
+
+ * The commits in a repository can be described by multiple
+ commit-graph files now, which allows the commit-graph files to be
+ updated incrementally.
+
+ * "git range-diff" output has been tweaked for easier identification
+ of which part of what file the patch shown is about.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Update supporting parts of "git rebase" to remove code that should
+ no longer be used.
+
+ * Developer support to emulate unsatisfied prerequisites in tests to
+ ensure that the remainder of the tests still succeeds when tests
+ with prerequisites are skipped.
+
+ * "git update-server-info" learned not to rewrite the file with the
+ same contents.
+
+ * The way of specifying the path to find dynamic libraries at runtime
+ has been simplified. The old default to pass -R/path/to/dir has been
+ replaced with the new default to pass -Wl,-rpath,/path/to/dir,
+ which is the more recent GCC uses. Those who need to build with an
+ old GCC can still use "CC_LD_DYNPATH=-R"
+
+ * Prepare use of reachability index in topological walker that works
+ on a range (A..B).
+
+ * A new tutorial targeting specifically aspiring git-core
+ developers has been added.
+
+ * Auto-detect how to tell HP-UX aCC where to use dynamically linked
+ libraries from at runtime.
+
+ * "git mergetool" and its tests now spawn fewer subprocesses.
+
+ * Dev support update to help tracing out tests.
+
+ * Support to build with MSVC has been updated.
+
+ * "git fetch" that grabs from a group of remotes learned to run the
+ auto-gc only once at the very end.
+
+ * A handful of Windows build patches have been upstreamed.
+
+ * The code to read state files used by the sequencer machinery for
+ "git status" has been made more robust against a corrupt or stale
+ state files.
+
+ * "git for-each-ref" with multiple patterns have been optimized.
+
+ * The tree-walk API learned to pass an in-core repository
+ instance throughout more codepaths.
+
+ * When one step in multi step cherry-pick or revert is reset or
+ committed, the command line prompt script failed to notice the
+ current status, which has been improved.
+
+ * Many GIT_TEST_* environment variables control various aspects of
+ how our tests are run, but a few followed "non-empty is true, empty
+ or unset is false" while others followed the usual "there are a few
+ ways to spell true, like yes, on, etc., and also ways to spell
+ false, like no, off, etc." convention.
+
+ * Adjust the dir-iterator API and apply it to the local clone
+ optimization codepath.
+
+ * We have been trying out a few language features outside c89; the
+ coding guidelines document did not talk about them and instead had
+ a blanket ban against them.
+
+ * A test helper has been introduced to optimize preparation of test
+ repositories with many simple commits, and a handful of test
+ scripts have been updated to use it.

+ backend was mixed up, leading to an unrelated file descriptor getting
+ closed, which has been fixed.
+
+ * A "merge -c" instruction during "git rebase --rebase-merges" should
+ give the user a chance to edit the log message, even when there is
+ otherwise no need to create a new merge and replace the existing
+ one (i.e. fast-forward instead), but did not. Which has been
+ corrected.
+
+ * Code cleanup and futureproof.
+
+ * More parameter validation.
+
+ * "git update-server-info" used to leave stale packfiles in its

+
+ * The list of for-each like macros used by clang-format has been

+
+ * "git branch --list" learned to show branches that are checked out
+ in other worktrees connected to the same repository prefixed with
+ '+', similar to the way the currently checked out branch is shown
+ with '*' in front.
+ (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).
+
+ * Code restructuring during 2.20 period broke fetching tags via
+ "import" based transports.
+
+ * The commit-graph file is now part of the "files that the runtime

+ (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
+
+ * "git rm" to resolve a conflicted path leaked an internal message

+Git 2.24 Release Notes
+======================
+
+Updates since v2.23
+-------------------
+
+Backward compatibility note
+
+ * Although it is not officially deprecated, "filter-branch" is
+ showing its age and alternatives are available. From this release,
+ we started to discourage its uses and hint people about
+ filter-repo.
+
+UI, Workflows & Features
+
+ * We now have an active interim maintainer for the Git-Gui part of
+ the system. Praise and thank Pratyush Yadav for volunteering.
+
+ * The command line parser learned "--end-of-options" notation; the
+ standard convention for scripters to have hardcoded set of options
+ first on the command line, and force the command to treat end-user
+ input as non-options, has been to use "--" as the delimiter, but
+ that would not work for commands that use "--" as a delimiter
+ between revs and pathspec.
+
+ * A mechanism to affect the default setting for a (related) group of
+ configuration variables is introduced.
+
+ * "git fetch" learned "--set-upstream" option to help those who first
+ clone from their private fork they intend to push to, add the true
+ upstream via "git remote add" and then "git fetch" from it.
+
+ * Device-tree files learned their own userdiff patterns.
+ (merge 3c81760bc6 sb/userdiff-dts later to maint).
+
+ * "git rebase --rebase-merges" learned to drive different merge
+ strategies and pass strategy specific options to them.
+
+ * A new "pre-merge-commit" hook has been introduced.
+
+ * Command line completion updates for "git -c var.name=val" have been
+ added.
+
+ * The lazy clone machinery has been taught that there can be more
+ than one promisor remote and consult them in order when downloading
+ missing objects on demand.
+
+ * The list-objects-filter API (used to create a sparse/lazy clone)
+ learned to take a combined filter specification.
+
+ * The documentation and tests for "git format-patch" have been
+ cleaned up.
+
+ * On Windows, the root level of UNC share is now allowed to be used
+ just like any other directory.
+
+ * The command line completion support (in contrib/) learned about the
+ "--skip" option of "git revert" and "git cherry-pick".
+
+ * "git rebase --keep-base <upstream>" tries to find the original base
+ of the topic being rebased and rebase on top of that same base,
+ which is useful when running the "git rebase -i" (and its limited
+ variant "git rebase -x").
+
+ The command also has learned to fast-forward in more cases where it
+ can instead of replaying to recreate identical commits.
+
+ * A configuration variable tells "git fetch" to write the commit
+ graph after finishing.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The code to write commit-graph over given commit object names has
+ been made a bit more robust.
+
+ * The first line of verbose output from each test piece now carries
+ the test name and number to help scanning with eyeballs.
+
+ * Further clean-up of the initialization code.
+
+ * xmalloc() used to have a mechanism to ditch memory and address
+ space resources as the last resort upon seeing an allocation
+ failure from the underlying malloc(), which made the code complex
+ and thread-unsafe with dubious benefit, as major memory resource
+ users already do limit their uses with various other mechanisms.
+ It has been simplified away.
+
+ * Unnecessary full-tree diff in "git log -L" machinery has been
+ optimized away.
+
+ * The http transport lacked some optimization the native transports
+ learned to avoid unnecessary ref advertisement, which has been
+ corrected.
+
+ * Preparation for SHA-256 upgrade continues in the test department.
+ (merge 0c37c41d13 bc/hash-independent-tests-part-5 later to maint).
+
+ * The memory ownership model of the "git fast-import" got
+ straightened out.
+
+ * Output from trace2 subsystem is formatted more prettily now.
+
+ * The internal code originally invented for ".gitignore" processing
+ got reshuffled and renamed to make it less tied to "excluding" and
+ stress more that it is about "matching", as it has been reused for
+ things like sparse checkout specification that want to check if a
+ path is "included".
+
+ * "git stash" learned to write refreshed index back to disk.
+
+ * Coccinelle checks are done on more source files than before now.
+
+ * The cache-tree code has been taught to be less aggressive in
+ attempting to see if a tree object it computed already exists in
+ the repository.
+
+ * The code to parse and use the commit-graph file has been made more
+ robust against corrupted input.
+
+ * The hg-to-git script (in contrib/) has been updated to work with
+ Python 3.
+
+ * Update the way build artifacts in t/helper/ directory are ignored.
+
+
+Fixes since v2.23
+-----------------
+
+ * "git grep --recurse-submodules" that looks at the working tree
+ files looked at the contents in the index in submodules, instead of
+ files in the working tree.
+ (merge 6a289d45c0 mt/grep-submodules-working-tree later to maint).
+
+ * Codepaths to walk tree objects have been audited for integer
+ overflows and hardened.
+ (merge 5aa02f9868 jk/tree-walk-overflow later to maint).
+
+ * "git pack-refs" can lose refs that are created while running, which
+ is getting corrected.
+ (merge a613d4f817 sc/pack-refs-deletion-racefix later to maint).
+
+ * "git checkout" and "git restore" to re-populate the index from a
+ tree-ish (typically HEAD) did not work correctly for a path that
+ was removed and then added again with the intent-to-add bit, when
+ the corresponding working tree file was empty. This has been
+ corrected.
+
+ * Compilation fix.
+ (merge 70597e8386 rs/nedalloc-fixlets later to maint).
+
+ * "git gui" learned to call the clean-up procedure before exiting.
+ (merge 0d88f3d2c5 py/git-gui-do-quit later to maint).
+
+ * We promoted the "indent heuristics" that decides where to split
+ diff hunks from experimental to the default a few years ago, but
+ some stale documentation still marked it as experimental, which has
+ been corrected.
+ (merge 64e5e1fba1 sg/diff-indent-heuristic-non-experimental later to maint).
+
+ * Fix a mismerge that happened in 2.22 timeframe.
+ (merge acb7da05ac en/checkout-mismerge-fix later to maint).
+
+ * "git archive" recorded incorrect length in extended pax header in
+ some corner cases, which has been corrected.
+ (merge 71d41ff651 rs/pax-extended-header-length-fix later to maint).
+
+ * On-demand object fetching in lazy clone incorrectly tried to fetch
+ commits from submodule projects, while still working in the
+ superproject, which has been corrected.
+ (merge a63694f523 jt/diff-lazy-fetch-submodule-fix later to maint).
+
+ * Prepare get_short_oid() codepath to be thread-safe.
+ (merge 7cfcb16b0e rs/sort-oid-array-thread-safe later to maint).
+
+ * "for-each-ref" and friends that show refs did not protect themselves
+ against ancient tags that did not record tagger names when asked to
+ show "%(taggername)", which have been corrected.
+ (merge 8b3f33ef11 mp/for-each-ref-missing-name-or-email later to maint).
+
+ * The "git am" based backend of "git rebase" ignored the result of
+ updating ".gitattributes" done in one step when replaying
+ subsequent steps.
+ (merge 2c65d90f75 bc/reread-attributes-during-rebase later to maint).
+
+ * Tell cURL library to use the same malloc() implementation, with the
+ xmalloc() wrapper, as the rest of the system, for consistency.
+ (merge 93b980e58f cb/curl-use-xmalloc later to maint).
+
+ * Build fix to adjust .gitignore to unignore a path that we started to track.
+ (merge aac6ff7b5b js/visual-studio later to maint).
+
+ * A few implementation fixes in the notes API.
+ (merge 60fe477a0b mh/notes-duplicate-entries later to maint).
+
+ * Fix an earlier regression to "git push --all" which should have
+ been forbidden when the target remote repository is set to be a
+ mirror.
+ (merge 8e4c8af058 tg/push-all-in-mirror-forbidden later to maint).
+
+ * Fix an earlier regression in the test suite, which mistakenly
+ stopped running HTTPD tests.
+ (merge 3960290675 sg/git-test-boolean later to maint).
+
+ * "git rebase --autostash <upstream> <branch>", when <branch> is
+ different from the current branch, incorrectly moved the tip of the
+ current branch, which has been corrected.
+ (merge bf1e28e0ad bw/rebase-autostash-keep-current-branch later to maint).
+
+ * Update support for Asciidoctor documentation toolchain.
+ (merge 83b0b8953e ma/asciidoctor-refmiscinfo later to maint).
+
+ * Start using DocBook 5 (instead of DocBook 4.5) as Asciidoctor 2.0
+ no longer works with the older one.
+ (merge f6461b82b9 bc/doc-use-docbook-5 later to maint).
+
+ * The markup used in user-manual has been updated to work better with
+ asciidoctor.
+ (merge c4d2f6143a ma/user-manual-markup-update later to maint).
+
+ * Make sure the grep machinery does not abort when seeing a payload
+ that is not UTF-8 even when JIT is not in use with PCRE1.
+ (merge ad7c543e3b cb/skip-utf8-check-with-pcre1 later to maint).
+
+ * The name of the blob object that stores the filter specification
+ for sparse cloning/fetching was interpreted in a wrong place in the
+ code, causing Git to abort.
+
+ * "git log --decorate-refs-exclude=<pattern>" was incorrectly
+ overruled when the "--simplify-by-decoration" option is used, which
+ has been corrected.
+ (merge 0cc7380d88 rs/simplify-by-deco-with-deco-refs-exclude later to maint).
+
+ * The "upload-pack" (the counterpart of "git fetch") needs to disable
+ commit-graph when responding to a shallow clone/fetch request, but
+ the way this was done made Git panic, which has been corrected.
+
+ * The object traversal machinery has been optimized not to load tree
+ objects when we are only interested in commit history.
+ (merge 72ed80c784 jk/list-objects-optim-wo-trees later to maint).
+
+ * The object name parser for "Nth parent" syntax has been made more
+ robust against integer overflows.
+ (merge 59fa5f5a25 rs/nth-parent-parse later to maint).
+
+ * The code used in following tags in "git fetch" has been optimized.
+ (merge b7e2d8bca5 ms/fetch-follow-tag-optim later to maint).
+
+ * Regression fix for progress output.
+ (merge 2bb74b53a4 sg/progress-fix later to maint).
+
+ * A bug in merge-recursive code that triggers when a branch with a
+ symbolic link is merged with a branch that replaces it with a
+ directory has been fixed.
+ (merge 83e3ad3b12 jt/merge-recursive-symlink-is-not-a-dir-in-way later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.
+ (merge d1387d3895 en/fast-import-merge-doc later to maint).
