+Git 2.25 Release Notes
+======================
+
+Updates since v2.24
+-------------------
+
+Backward compatibility notes
+
+
+UI, Workflows & Features
+
+ * A tutorial on object enumeration has been added.
+
+ * The branch description ("git branch --edit-description") has been
+   used to fill the body of the cover letters by the format-patch
+   command; this has been enhanced so that the subject can also be
+   filled.
+
+ * "git rebase --preserve-merges" has been marked as deprecated; this
+   release stops advertising it in the "git rebase -h" output.
+
+ * The code to generate multi-pack index learned to show (or not to
+   show) progress indicators.
+
+ * "git apply --3way" learned to honor merge.conflictStyle
+   configuration variable, like merges would.
+
+ * The custom format for "git log --format=<format>" learned the l/L
+   placeholder that is similar to e/E that fills in the e-mail
+   address, but only the local part on the left side of '@'.
+
+ * Documentation pages for "git shortlog" now list commit limiting
+   options explicitly.
+
+ * The patterns to detect function boundary for Elixir language has
+   been added.
+
+ * The completion script (in contrib/) learned that the "--onto"
+   option of "git rebase" can take its argument as the value of the
+   option.
+
+ * The userdiff machinery has been taught that "async def" is another
+   way to begin a "function" in Python.
+
+ * "git range-diff" learned to take the "--notes=<ref>" and the
+   "--no-notes" options to control the commit notes included in the
+   log message that gets compared.
+
+ * "git rev-parse --show-toplevel" run outside of any working tree did
+   not error out, which has been corrected.
+
+ * A few commands learned to take the pathspec from the standard input
+   or a named file, instead of taking it as the command line
+   arguments, with the "--pathspec-from-file" option.
+
+ * "git submodule" learned a subcommand "set-url".
+
+ * "git log" family learned "--pretty=reference" that gives the name
+   of a commit in the format that is often used to refer to it in log
+   messages.
+
+ * The interaction between "git clone --recurse-submodules" and
+   alternate object store was ill-designed.  The documentation and
+   code have been taught to make more clear recommendations when the
+   users see failures.
+
+ * Management of sparsely checked-out working tree has gained a
+   dedicated "sparse-checkout" command.
+
+ * Miscellaneous small UX improvements on "git-p4".
+
+ * "git sparse-checkout list" subcommand learned to give its output in
+   a more concise form when the "cone" mode is in effect.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Debugging support for lazy cloning has been a bit improved.
+
+ * Move the definition of a set of bitmask constants from 0ctal
+   literal to (1U<<count) notation.
+
+ * Test updates to prepare for SHA-2 transition continues.
+
+ * Crufty code and logic accumulated over time around the object
+   parsing and low-level object access used in "git fsck" have been
+   cleaned up.
+
+ * The implementation of "git log --graph" got refactored and then its
+   output got simplified.
+
+ * Follow recent push to move API docs from Documentation/ to header
+   files and update config.h
+
+ * "git bundle" has been taught to use the parse options API.  "git
+   bundle verify" learned "--quiet" and "git bundle create" learned
+   options to control the progress output.
+
+ * Handling of commit objects that use non UTF-8 encoding during
+   "rebase -i" has been improved.
+
+ * The beginning of rewriting "git add -i" in C.
+
+ * A label used in the todo list that are generated by "git rebase
+   --rebase-merges" is used as a part of a refname; the logic to come
+   up with the label has been tightened to avoid names that cannot be
+   used as such.
+
+ * The logic to avoid duplicate label names generated by "git rebase
+   --rebase-merges" forgot that the machinery itself uses "onto" as a
+   label name, which must be avoided by auto-generated labels, which
+   has been corrected.
+
+ * We have had compatibility fallback macro definitions for "PRIuMAX",
+   "PRIu32", etc. but did not for "PRIdMAX", while the code used the
+   last one apparently without any hiccup reported recently.  The
+   fallback macro definitions for these <inttypes.h> macros that must
+   appear in C99 systems have been removed.
+
+ * Recently we have declared that GIT_TEST_* variables take the
+   usual boolean values (it used to be that some used "non-empty
+   means true" and taking GIT_TEST_VAR=YesPlease as true); make
+   sure we notice and fail when non-bool strings are given to
+   these variables.
+
+ * Users of oneway_merge() (like "reset --hard") learned to take
+   advantage of fsmonitor to avoid unnecessary lstat(2) calls.
+
+ * Performance tweak on "git push" into a repository with many refs
+   that point at objects we have never heard of.
+
+ * PerfTest fix to avoid stale result mixed up with the latest round
+   of test results.
+
+ * Hide lower-level verify_signed-buffer() API as a pure helper to
+   implement the public check_signature() function, in order to
+   encourage new callers to use the correct and more strict
+   validation.
+
+ * Unnecessary reading of state variables back from the disk during
+   sequencer operation has been reduced.
+
+ * The code has been made to avoid gmtime() and localtime() and prefer
+   their reentrant counterparts.
+
+ * In a repository with many packfiles, the cost of the procedure that
+   avoids registering the same packfile twice was unnecessarily high
+   by using an inefficient search algorithm, which has been corrected.
+
+ * Redo "git name-rev" to avoid recursive calls.
+
+ * FreeBSD CI support via Cirrus-CI has been added.
+
+
+Fixes since v2.24
+-----------------
+
+ * "rebase -i" ceased to run post-commit hook by mistake in an earlier
+   update, which has been corrected.
+
+ * "git notes copy $original" ought to copy the notes attached to the
+   original object to HEAD, but a mistaken tightening to command line
+   parameter validation made earlier disabled that feature by mistake.
+
+ * When all files from some subdirectory were renamed to the root
+   directory, the directory rename heuristics would fail to detect that
+   as a rename/merge of the subdirectory to the root directory, which has
+   been corrected.
+
+ * Code clean-up and a bugfix in the logic used to tell worktree local
+   and repository global refs apart.
+   (merge f45f88b2e4 sg/dir-trie-fixes later to maint).
+
+ * "git stash save" in a working tree that is sparsely checked out
+   mistakenly removed paths that are outside the area of interest.
+   (merge 4a58c3d7f7 js/update-index-ignore-removal-for-skip-worktree later to maint).
+
+ * "git rev-parse --git-path HEAD.lock" did not give the right path
+   when run in a secondary worktree.
+   (merge 76a53d640f js/git-path-head-dot-lock-fix later to maint).
+
+ * "git merge --no-commit" needs "--no-ff" if you do not want to move
+   HEAD, which has been corrected in the manual page for "git bisect".
+   (merge 8dd327b246 ma/bisect-doc-sample-update later to maint).
+
+ * "git worktree add" internally calls "reset --hard" that should not
+   descend into submodules, even when submodule.recurse configuration
+   is set, but it was affected.  This has been corrected.
+   (merge 4782cf2ab6 pb/no-recursive-reset-hard-in-worktree-add later to maint).
+
+ * Messages from die() etc. can be mixed up from multiple processes
+   without even line buffering on Windows, which has been worked
+   around.
+   (merge 116d1fa6c6 js/vreportf-wo-buffering later to maint).
+
+ * HTTP transport had possible allocator/deallocator mismatch, which
+   has been corrected.
+
+ * The watchman integration for fsmonitor was racy, which has been
+   corrected to be more conservative.
+   (merge dd0b61f577 kw/fsmonitor-watchman-fix later to maint).
+
+ * Fetching from multiple remotes into the same repository in parallel
+   had a bad interaction with the recent change to (optionally) update
+   the commit-graph after a fetch job finishes, as these parallel
+   fetches compete with each other.  Which has been corrected.
+
+ * Recent update to "git stash pop" made the command empty the index
+   when run with the "--quiet" option, which has been corrected.
+
+ * "git fetch" codepath had a big "do not lazily fetch missing objects
+   when I ask if something exists" switch.  This has been corrected by
+   marking the "does this thing exist?" calls with "if not please do not
+   lazily fetch it" flag.
+
+ * Test update to avoid wasted cycles.
+   (merge e0316695ec sg/skip-skipped-prereq later to maint).
+
+ * Error handling after "git push" finishes sending the packdata and
+   waits for the response to the remote side has been improved.
+   (merge ad7a403268 jk/send-pack-remote-failure later to maint).
+
+ * Some codepaths in "gitweb" that forgot to escape URLs generated
+   based on end-user input have been corrected.
+   (merge a376e37b2c jk/gitweb-anti-xss later to maint).
+
+ * CI jobs for macOS has been made less chatty when updating perforce
+   package used during testing.
+   (merge 0dbc4a0edf jc/azure-ci-osx-fix-fix later to maint).
+
+ * "git unpack-objects" used to show progress based only on the number
+   of received and unpacked objects, which stalled when it has to
+   handle an unusually large object.  It now shows the throughput as
+   well.
+   (merge bae60ba7e9 sg/unpack-progress-throughput later to maint).
+
+ * The sequencer machinery compared the HEAD and the state it is
+   attempting to commit to decide if the result would be a no-op
+   commit, even when amending a commit, which was incorrect, and
+   has been corrected.
+
+ * The code to parse GPG output used to assume incorrectly that the
+   finterprint for the primary key would always be present for a valid
+   signature, which has been corrected.
+   (merge 67a6ea6300 hi/gpg-optional-pkfp-fix later to maint).
+
+ * "git submodule status" and "git submodule status --cached" show
+   different things, but the documentation did not cover them
+   correctly, which has been corrected.
+   (merge 8d483c8408 mg/doc-submodule-status-cached later to maint).
+
+ * "git reset --patch $object" without any pathspec should allow a
+   tree object to be given, but incorrectly required a committish,
+   which has been corrected.
+
+ * "git submodule status" that is run from a subdirectory of the
+   superproject did not work well, which has been corrected.
+   (merge 1f3aea22c7 mg/submodule-status-from-a-subdirectory later to maint).
+
+ * The revision walking machinery uses resources like per-object flag
+   bits that need to be reset before a new iteration of walking
+   begins, but the resources related to topological walk were not
+   cleared correctly, which has been corrected.
+   (merge 0aa0c2b2ec mh/clear-topo-walk-upon-reset later to maint).
+
+ * TravisCI update.
+   (merge 176441bfb5 sg/osx-force-gcc-9 later to maint).
+
+ * While running "revert" or "cherry-pick --edit" for multiple
+   commits, a recent regression incorrectly detected "nothing to
+   commit, working tree clean", instead of replaying the commits,
+   which has been corrected.
+   (merge befd4f6a81 sg/assume-no-todo-update-in-cherry-pick later to maint).
+
+ * Work around a issue where a FD that is left open when spawning a
+   child process and is kept open in the child can interfere with the
+   operation in the parent process on Windows.
+
+ * One kind of progress messages were always given during commit-graph
+   generation, instead of following the "if it takes more than two
+   seconds, show progress" pattern, which has been corrected.
+
+ * "git rebase" did not work well when format.useAutoBase
+   configuration variable is set, which has been corrected.
+
+ * The "diff" machinery learned not to lose added/removed blank lines
+   in the context when --ignore-blank-lines and --function-context are
+   used at the same time.
+   (merge 0bb313a552 rs/xdiff-ignore-ws-w-func-context later to maint).
+
+ * The test on "fast-import" used to get stuck when "fast-import" died
+   in the middle.
+   (merge 0d9b0d7885 sg/t9300-robustify later to maint).
+
+ * "git format-patch" can take a set of configured format.notes values
+   to specify which notes refs to use in the log message part of the
+   output.  The behaviour of this was not consistent with multiple
+   --notes command line options, which has been corrected.
+   (merge e0f9095aaa dl/format-patch-notes-config-fixup later to maint).
+
+ * "git p4" used to ignore lfs.storage configuration variable, which
+   has been corrected.
+   (merge ea94b16fb8 rb/p4-lfs later to maint).
+
+ * Assorted fixes to the directory traversal API.
+   (merge 6836d2fe06 en/fill-directory-fixes later to maint).
+
+ * Forbid pathnames that the platform's filesystem cannot represent on
+   MinGW.
+   (merge 4dc42c6c18 js/mingw-reserved-filenames later to maint).
+
+ * "git rebase --signoff" stopped working when the command was written
+   in C, which has been corrected.
+   (merge 4fe7e43c53 en/rebase-signoff-fix later to maint).
+
+ * An earlier update to Git for Windows declared that a tree object is
+   invalid if it has a path component with backslash in it, which was
+   overly strict, which has been corrected.  The only protection the
+   Windows users need is to prevent such path (or any path that their
+   filesystem cannot check out) from entering the index.
+   (merge 224c7d70fa js/mingw-loosen-overstrict-tree-entry-checks later to maint).
+
+ * The code to write split commit-graph file(s) upon fetching computed
+   bogus value for the parameter used in splitting the resulting
+   files, which has been corrected.
+   (merge 63020f175f ds/commit-graph-set-size-mult later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.
+   (merge 80736d7c5e jc/am-show-current-patch-docfix later to maint).
+   (merge 8b656572ca sg/commit-graph-usage-fix later to maint).
