+Git v2.44 Release Notes
+=======================
+
+Backward Compatibility Notes
+
+ * "git chekcout -B <branch>" used to allow switching to a branch that
+ is in use on another worktree, but this was by mistake. The users
+ need to use "--ignore-other-worktrees" option.
+
+
+UI, Workflows & Features
+
+ * "git add" and "git stash" learned to support the ":(attr:...)"
+ magic pathspec.
+
+ * "git rebase --autosquash" is now enabled for non-interactive rebase,
+ but it is still incompatible with the apply backend.
+
+ * Introduce "git replay", a tool meant on the server side without
+ working tree to recreate a history.
+
+ * "git merge-file" learned to take the "--diff-algorithm" option to
+ use algorithm different from the default "myers" diff.
+
+ * Command line completion (in contrib/) learned to complete path
+ arguments to the "add/set" subcommands of "git sparse-checkout"
+ better.
+
+ * "git checkout -B <branch> [<start-point>]" allowed a branch that is
+ in use in another worktree to be updated and checked out, which
+ might be a bit unexpected. The rule has been tightened, which is a
+ breaking change. "--ignore-other-worktrees" option is required to
+ unbreak you, if you are used to the current behaviour that "-B"
+ overrides the safety.
+
+ * The builtin_objectmode attribute is populated for each path
+ without adding anything in .gitattributes files, which would be
+ useful in magic pathspec, e.g., ":(attr:builtin_objectmode=100755)"
+ to limit to executables.
+
+ * "git fetch" learned to pay attention to "fetch.all" configuration
+ variable, which pretends as if "--all" was passed from the command
+ line when no remote parameter was given.
+
+ * In addition to (rather cryptic) Security Identifiers, show username
+ and domain in the error message when we barf on mismatch between
+ the Git directory and the current user on Windows.
+
+ * The error message given when "git branch -d branch" fails due to
+ commits unique to the branch has been split into an error and a new
+ conditional advice message.
+
+ * When given an existing but unreadable file as a configuration file,
+ gitweb behaved as if the file did not exist at all, but now it
+ errors out. This is a change that may break backward compatibility.
+
+ * When $HOME/.gitignore is missing but XDG config file available, we
+ should write into the latter, not former. "git gc" and "git
+ maintenance" wrote into a wrong "global config" file, which have
+ been corrected.
+
+ * Define "special ref" as a very narrow set that consists of
+ FETCH_HEAD and MERGE_HEAD, and clarify everything else that used to
+ be classified as such are actually just pseudorefs.
+
+ * All conditional "advice" messages show how to turn them off, which
+ becomes repetitive. Setting advice.* configuration explicitly on
+ now omits the instruction part.
+
+ * The "disable repository discovery of a bare repository" check,
+ triggered by setting safe.bareRepository configuration variable to
+ 'explicit', has been loosened to exclude the ".git/" directory inside
+ a non-bare repository from the check. So you can do "cd .git &&
+ git cmd" to run a Git command that works on a bare repository without
+ explicitly specifying $GIT_DIR now.
+
+ * The completion script (in contrib/) learned more options that can
+ be used with "git log".
+
+ * The labels on conflict markers for the common ancestor, our version,
+ and the other version are available to custom 3-way merge driver
+ via %S, %X, and %Y placeholders.
+
+ * The write codepath for the reftable data learned to honor
+ core.fsync configuration.
+
+ * The "--fsck-objects" option of "git index-pack" now can take the
+ optional parameter to tweak severity of different fsck errors.
+
+ * The wincred credential backend has been taught to support oauth
+ refresh token the same way as credential-cache and
+ credential-libsecret backends.
+
+ * Command line completion support (in contrib/) has been
+ updated for "git bisect".
+
+ * "git branch" and friends learned to use the formatted text as
+ sorting key, not the underlying timestamp value, when the --sort
+ option is used with author or committer timestamp with a format
+ specifier (e.g., "--sort=creatordate:format:%H:%M:%S").
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Process to add some form of low-level unit tests has started.
+
+ * Add support for GitLab CI.
+
+ * "git for-each-ref --no-sort" still sorted the refs alphabetically
+ which paid non-trivial cost. It has been redefined to show output
+ in an unspecified order, to allow certain optimizations to take
+ advantage of.
+
+ * Simplify API implementation to delete references by eliminating
+ duplication.
+
+ * Subject approxidate() and show_date() machinery to OSS-Fuzz.
+
+ * A new helper to let us pretend that we called lstat() when we know
+ our cache_entry is up-to-date via fsmonitor.
+
+ * The optimization based on fsmonitor in the "diff --cached"
+ codepath is resurrected with the "fake-lstat" introduced earlier.
+
+ * Test balloon to use C99 "bool" type from <stdbool.h> has been
+ added.
+
+ * "git clone" has been prepared to allow cloning a repository with
+ non-default hash function into a repository that uses the reftable
+ backend.
+
+ * Streaming spans of packfile data used to be done only from a
+ single, primary, pack in a repository with multiple packfiles. It
+ has been extended to allow reuse from other packfiles, too.
+
+ * Comment updates to help developers not to attempt to modify
+ messages from plumbing commands that must stay constant.
+
+ It might make sense to reassess the plumbing needs every few years,
+ but that should be done as a separate effort.
+
+ * Move test-ctype helper to the unit-test framework.
+
+ * Instead of manually creating refs/ hierarchy on disk upon a
+ creation of a secondary worktree, which is only usable via the
+ files backend, use the refs API to populate it.
+
+ * CI for GitLab learned to drive macOS jobs.
+
+ * A few tests to "git commit -o <pathspec>" and "git commit -i
+ <pathspec>" has been added.
+
+ * Tests on ref API are moved around to prepare for reftable.
+
+ * The Makefile often had to say "-L$(path) -R$(path)" that repeats
+ the path to the same library directory for link time and runtime.
+ A Makefile template is used to reduce such repetition.
+
+ * The priority queue test has been migrated to the unit testing
+ framework.
+
+ * Setting `feature.experimental` opts the user into multi-pack reuse
+ experiment
+
+ * Squelch node.js 16 deprecation warnings from GitHub Actions CI
+ by updating actions/github-script and actions/checkout that use
+ node.js 20.
+
+ * The mechanism to report the filename in the source code, used by
+ the unit-test machinery, assumed that the compiler expanded __FILE__
+ to the path to the source given to the $(CC), but some compilers
+ give full path, breaking the output. This has been corrected.
+
+
+Fixes since v2.43
+-----------------
+
+ * The way CI testing used "prove" could lead to running the test
+ suite twice needlessly, which has been corrected.
+
+ * Update ref-related tests.
+
+ * "git format-patch --encode-email-headers" ignored the option when
+ preparing the cover letter, which has been corrected.
+
+ * Newer versions of Getopt::Long started giving warnings against our
+ (ab)use of it in "git send-email". Bump the minimum version
+ requirement for Perl to 5.8.1 (from September 2002) to allow
+ simplifying our implementation.
+
+ * Earlier we stopped relying on commit-graph that (still) records
+ information about commits that are lost from the object store,
+ which has negative performance implications. The default has been
+ flipped to disable this pessimization.
+
+ * Stale URLs have been updated to their current counterparts (or
+ archive.org) and HTTP links are replaced with working HTTPS links.
+
+ * trace2 streams used to record the URLs that potentially embed
+ authentication material, which has been corrected.
+
+ * The sample pre-commit hook that tries to catch introduction of new
+ paths that use potentially non-portable characters did not notice
+ an existing path getting renamed to such a problematic path, when
+ rename detection was enabled.
+
+ * The command line parser for the "log" family of commands was too
+ loose when parsing certain numbers, e.g., silently ignoring the
+ extra 'q' in "git log -n 1q" without complaining, which has been
+ tightened up.
+
+ * "git $cmd --end-of-options --rev -- --path" for some $cmd failed
+ to interpret "--rev" as a rev, and "--path" as a path. This was
+ fixed for many programs like "reset" and "checkout".
+
+ * "git bisect reset" has been taught to clean up state files and refs
+ even when BISECT_START file is gone.
+
+ * Some codepaths did not correctly parse configuration variables
+ specified with valueless "true", which has been corrected.
+
+ * Code clean-up for sanity checking of command line options for "git
+ show-ref".
+
+ * The code to parse the From e-mail header has been updated to avoid
+ recursion.
+
+ * "git fetch --atomic" issued an unnecessary empty error message,
+ which has been corrected.
+
+ * Command line completion script (in contrib/) learned to work better
+ with the reftable backend.
+
+ * "git status" is taught to show both the branch being bisected and
+ being rebased when both are in effect at the same time.
+
+ * "git archive --list extra garbage" silently ignored excess command
+ line parameters, which has been corrected.
+
+ * "git sparse-checkout set" added default patterns even when the
+ patterns are being fed from the standard input, which has been
+ corrected.
+
+ * "git sparse-checkout (add|set) --[no-]cone --end-of-options" did
+ not handle "--end-of-options" correctly after a recent update.
+
+ * Unlike other environment variables that took the usual
+ true/false/yes/no as well as 0/1, GIT_FLUSH only understood 0/1,
+ which has been corrected.
+
+ * Clearing in-core repository (happens during e.g., "git fetch
+ --recurse-submodules" with commit graph enabled) made in-core
+ commit object in an inconsistent state by discarding the necessary
+ data from commit-graph too early, which has been corrected.
+
+ * Update to a new feature recently added, "git show-ref --exists".

+
+ * oss-fuzz tests are built and run in CI.
+ (merge c4a9cf1df3 js/oss-fuzz-build-in-ci later to maint).
+

+ incomplete line.

+
+ * GitHub CI update.

+
+ * "git diff --no-rename A B" did not disable rename detection but did
+ not trigger an error from the command line parser.
- (merge 85a9a63c92 jk/diff-external-with-no-index later to maint).
+
+ * "git archive --remote=<remote>" learned to talk over the smart
+ http (aka stateless) transport.
+ (merge 176cd68634 jx/remote-archive-over-smart-http later to maint).
+
+ * Fetching via protocol v0 over Smart HTTP transport sometimes failed
+ to correctly auto-follow tags.
+ (merge fba732c462 jk/fetch-auto-tag-following-fix later to maint).
+
+ * The documentation for the --exclude-per-directory option marked it
+ as deprecated, which confused readers into thinking there may be a
+ plan to remove it in the future, which was not our intention.
+ (merge 0009542cab jc/ls-files-doc-update later to maint).
+
+ * "git diff --no-index file1 file2" segfaulted while invoking the
+ external diff driver, which has been corrected.
- (merge de65079d7b jc/comment-style-fixes later to maint).

- (merge 6931049c32 jc/sign-buffer-failure-propagation-fix later to maint).
+
+ * Cirrus CI jobs started breaking because we specified version of
+ FreeBSD that is no longer available, which has been corrected.
+ (merge 81fffb66d3 cb/use-freebsd-13-2-at-cirrus-ci later to maint).
+
+ * A caller called index_file_exists() that takes a string expressed
+ as <ptr, length> with a wrong length, which has been corrected.
+ (merge 156e28b36d jh/sparse-index-expand-to-path-fix later to maint).
+
+ * A failed "git tag -s" did not necessarily result in an error
+ depending on the crypto backend, which has been corrected.
- (merge d2058cb2f0 ps/report-failure-from-git-stash later to maint).
+
+ * "git stash" sometimes was silent even when it failed due to
+ unwritable index file, which has been corrected.
- (merge b40ba17e44 cp/git-flush-is-an-env-bool later to maint).
+
+ * "git show-ref --verify" did not show things like "CHERRY_PICK_HEAD",
+ which has been corrected.
+
+ * Recent conversion to allow more than 0/1 in GIT_FLUSH broke the
+ mechanism by flipping what yes/no means by mistake, which has been
+ corrected.
- (merge 8f50984cf4 ne/doc-filter-blob-limit-fix later to maint).
