+Git 2.24 Release Notes
+======================
+
+Updates since v2.23
+-------------------
+
+Backward compatibility note
+
+ * "filter-branch" is showing its age and alternatives are available.
+   From this release, we started to discourage its use 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.
+
+ * "git add -i" has been taught to show the total number of hunks and
+   the hunks that has been processed so far when showing prompts.
+
+ * "git fetch --jobs=<n>" allowed <n> parallel jobs when fetching
+   submodules, but this did not apply to "git fetch --multiple" that
+   fetches from multiple remote repositories.  It now does.
+
+ * The installation instruction for zsh completion script (in
+   contrib/) has been a bit improved.
+
+
+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.
+
+ * Preparation for SHA-256 upgrade continues.
+
+ * "git log --graph" for an octopus merge is sometimes colored
+   incorrectly, which is demonstrated and documented but not yet
+   fixed.
+
+ * The trace2 output, when sending them to files in a designated
+   directory, can populate the directory with too many files; a
+   mechanism is introduced to set the maximum number of files and
+   discard further logs when the maximum is reached.
+
+ * We have adopted a Code-of-conduct document.
+   (merge 3f9ef874a7 jk/coc later to maint).
+
+
+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).
+
+ * The rename detection logic sorts a list of rename source candidates
+   by similarity to pick the best candidate, which means that a tie
+   between sources with the same similarity is broken by the original
+   location in the original candidate list (which is sorted by path).
+   Force the sorting by similarity done with a stable sort, which is
+   not promised by system supplied qsort(3), to ensure consistent
+   results across platforms.
+   (merge 2049b8dc65 js/diff-rename-force-stable-sort later to maint).
+
+ * The code to skip "UTF" and "UTF-" prefix, when computing an advice
+   message, did not work correctly when the prefix was "UTF", which
+   has been fixed.
+   (merge b181676ce9 rs/convert-fix-utf-without-dash later to maint).
+
+ * The author names taken from SVN repositories may have extra leading
+   or trailing whitespaces, which are now munged away.
+   (merge 4ddd4bddb1 tk/git-svn-trim-author-name later to maint).
+
+ * "git rebase -i" showed a wrong HEAD while "reword" open the editor.
+   (merge b0a3186140 pw/rebase-i-show-HEAD-to-reword later to maint).
+
+ * A few simplification and bugfixes to PCRE interface.
+   (merge c581e4a749 ab/pcre-jit-fixes later to maint).
+
+ * PCRE fixes.
+   (merge ff61681b46 cb/pcre1-cleanup later to maint).
+
+ * "git range-diff" segfaulted when diff.noprefix configuration was
+   used, as it blindly expected the patch it internally generates to
+   have the standard a/ and b/ prefixes.  The command now forces the
+   internal patch to be built without any prefix, not to be affected
+   by any end-user configuration.
+   (merge 937b76ed49 js/range-diff-noprefix later to maint).
+
+ * "git stash apply" in a subdirectory of a secondary worktree failed
+   to access the worktree correctly, which has been corrected.
+   (merge dfd557c978 js/stash-apply-in-secondary-worktree later to maint).
+
+ * The merge-recursive machinery is one of the most complex parts of
+   the system that accumulated cruft over time.  This large series
+   cleans up the implementation quite a bit.
+   (merge b657047719 en/merge-recursive-cleanup later to maint).
+
+ * Pretty-printed command line formatter (used in e.g. reporting the
+   command being run by the tracing API) had a bug that lost an
+   argument that is an empty string, which has been corrected.
+   (merge ce2d7ed2fd gs/sq-quote-buf-pretty later to maint).
+
+ * "git range-diff" failed to handle mode-only change, which has been
+   corrected.
+   (merge 2b6a9b13ca tg/range-diff-output-update later to maint).
+
+ * Dev support update.
+   (merge 4f3c1dc5d6 dl/allow-running-cocci-verbosely later to maint).
+
+ * "git format-patch -o <outdir>" did an equivalent of "mkdir <outdir>"
+   not "mkdir -p <outdir>", which was corrected.
+
+ * "git stash save" lost local changes to submodules, which has been
+   corrected.
+   (merge 556895d0c8 jj/stash-reset-only-toplevel later to maint).
+
+ * The atomic push over smart HTTP transport did not work, which has
+   been corrected.
+   (merge 6f1194246a bc/smart-http-atomic-push later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.
+   (merge d1387d3895 en/fast-import-merge-doc later to maint).
+   (merge 1c24a54ea4 bm/repository-layout-typofix later to maint).
