* "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-shown-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 with "--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".
+
Performance, Internal Implementation, Development Support etc.
* A new tutorial targetting 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.
Fixes since v2.22
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.
+ (merge 810e19322d jt/partial-clone-missing-ref-delta-base later to maint).
+
+ * 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.
+ (merge 7140600e2e md/list-objects-filter-memfix later to maint).
+
+ * The description about slashes in gitignore patterns (used to
+ indicate things like "anchored to this level only" and "only
+ matches directories") has been revamped.
+ (merge 1a58bad014 an/ignore-doc-update later to maint).
+
+ * The URL decoding code has been updated to avoid going past the end
+ of the string while parsing %-<hex>-<hex> sequence.
+ (merge d37dc239a4 md/url-parse-harden later to maint).
+
+ * The list of for-each like macros used by clang-format has been
+ updated.
+ (merge fc7e03aace mo/clang-format-for-each-update later to maint).
+
+ * "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.
+ (merge f80d922355 fc/fetch-with-import-fix later to maint).
+
+ * 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.
+ (merge 2d511cfc0b ds/close-object-store later to maint).
+
+ * "git checkout -p" needs to selectively apply a patch in reverse,
+ which did not work well.
+ (merge 2bd69b9024 pw/add-p-recount later to maint).
+
+ * Code clean-up to avoid signed integer wraparounds during binary search.
+ (merge 568a05c5ec rs/avoid-overflow-in-midpoint-computation later to maint).
+
+ * "git interpret-trailers" always treated '#' as the comment
+ character, regardless of core.commentChar setting, which has been
+ corrected.
+ (merge 29c83fc23f jk/trailers-use-config later to maint).
+
+ * "git stash show 23" used to work, but no more after getting
+ rewritten in C; this regression has been corrected.
+ (merge 63b50c8ffe tg/stash-ref-by-index-fix later to maint).
+
+ * "git rebase --abort" used to leave refs/rewritten/ when concluding
+ "git rebase -r", which has been corrected.
+ (merge d559f502c5 pw/rebase-abort-clean-rewritten later to maint).
+
+ * 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.
+ (merge 69702523af nd/completion-no-cache-failure later to maint).
+
+ * The code to parse scaled numbers out of configuration files has
+ been made more robust and also easier to follow.
+ (merge 39c575c969 rs/config-unit-parsing later to maint).
+
+ * The codepath to compute delta islands used to spew progress output
+ without giving the callers any way to squelch it, which has been
+ fixed.
+ (merge bdbdf42f8a jk/delta-islands-progress-fix later to maint).
+
+ * 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.
+ (merge 5b12e3123b sg/rebase-progress later to maint).
+
+ * "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.
+ (merge 30db18b148 ms/submodule-foreach-fix later to maint).
+
* Other code cleanup, docfix, build fix, etc.
