-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.
-
-
-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 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
-   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 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
-   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.
-
- * "git checkout -p" needs to selectively apply a patch in reverse,
-   which did not work well.
-
- * Code clean-up to avoid signed integer wraparounds during binary search.
-
- * "git interpret-trailers" always treated '#' as the comment
-   character, regardless of core.commentChar setting, 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 rebase --abort" used to leave refs/rewritten/ when concluding
-   "git rebase -r", which has been corrected.
-
- * 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.
-
- * The code to parse scaled numbers out of configuration files has
-   been made more robust and also easier to follow.
-
- * The codepath to compute delta islands used to spew progress output
-   without giving the callers any way to squelch it, which has been
-   fixed.
-
- * Protocol capabilities that go over wire should never be translated,
-   but it was incorrectly marked for translation, which has been
-   corrected.  The output of protocol capabilities for debugging has
-   been tweaked a bit.
-
- * Use "Erase in Line" CSI sequence that is already used in the editor
-   support to clear cruft in the progress output.
-
- * "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.
-
- * 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.
-
- * 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.
-
- * Generation of pack bitmaps are now disabled when .keep files exist,
-   as these are mutually exclusive features.
-   (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
-
- * "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.
-
- * "git stash --keep-index" did not work correctly on paths that have
-   been removed, which has been fixed.
-   (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).
-
- * Window 7 update ;-)
-
- * A codepath that reads from GPG for signed object verification read
-   past the end of allocated buffer, which has been fixed.
-
- * "git clean" silently skipped a path when it cannot lstat() it; now
-   it gives a warning.
-
- * "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.
-
- * The internal diff machinery can be made to read out of bounds while
-   looking for --function-context line in a corner case, which has been
-   corrected.
-   (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).
-
- * Other code cleanup, docfix, build fix, etc.
-   (merge fbec05c210 cc/test-oidmap later to maint).
-   (merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint).
-   (merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint).
-   (merge d61e6ce1dd sg/fsck-config-in-doc later to maint).
