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
* "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.
no longer be used.
* Developer support to emulate unsatisfied prerequisites in tests to
- ensure that the remainer of the tests still succeeds when tests
+ 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
* Prepare use of reachability index in topological walker that works
on a range (A..B).
- * A new tutorial targetting specifically aspiring git-core
+ * 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
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.
- (merge e1df7fe43f nd/init-relative-template-fix later to maint).
* "git worktree add" used to fail when another worktree connected to
the same repository was corrupt, which has been corrected.
- (merge 105df73e71 nd/corrupt-worktrees later to maint).
* The ownership rule for the file descriptor to fast-import remote

closed, which has been fixed.
- (merge 3203566a71 mh/import-transport-fd-fix later to maint).
* A "merge -c" instruction during "git rebase --rebase-merges" should
give the user a chance to edit the log message, even when there is
corrected.
* Code cleanup and futureproof.
- (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint).
* More parameter validation.
- (merge de99eb0c24 es/grep-require-name-when-needed later to maint).
* "git update-server-info" used to leave stale packfiles in its
output, which has been corrected.
- (merge e941c48d49 ew/server-info-remove-crufts later to maint).
* 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.
- (merge 533e088250 jk/HEAD-symref-in-xfer-namespaces later to maint).
* "git am -i --resolved" segfaulted after trying to see a commit as
if it were a tree, which has been corrected.
- (merge 7663e438c5 jk/am-i-resolved-fix later to maint).
* "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.
- (merge 3bbbe467f2 js/bundle-verify-require-object-store later to maint).
* "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.
- (merge 1d14d0c994 vv/merge-squash-with-explicit-commit later to maint).
* The data collected by fsmonitor was not properly written back to
the on-disk index file, breaking t7519 tests occasionally, which
has been corrected.
- (merge b5a8169752 js/fsmonitor-unflake later to maint).
* Update to Unicode 12.1 width table.
- (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint).
* 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.
- (merge c3f2358de3 mm/p4-unshelve-windows-fix later to maint).
* "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.
- (merge 0454220d66 pb/request-pull-verify-remote-ref later to maint).
* 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.
- (merge 1c4a9f9114 xl/record-partial-clone-origin later to maint).
+
+ * "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.
