+Git v2.14.6 Release Notes
+=========================
+
+This release addresses the security issues CVE-2019-1348,
+CVE-2019-1349, CVE-2019-1350, CVE-2019-1351, CVE-2019-1352,
+CVE-2019-1353, CVE-2019-1354, and CVE-2019-1387.
+
+Fixes since v2.14.5
+-------------------
+
+ * CVE-2019-1348:
+   The --export-marks option of git fast-import is exposed also via
+   the in-stream command feature export-marks=... and it allows
+   overwriting arbitrary paths.
+
+ * CVE-2019-1349:
+   When submodules are cloned recursively, under certain circumstances
+   Git could be fooled into using the same Git directory twice. We now
+   require the directory to be empty.
+
+ * CVE-2019-1350:
+   Incorrect quoting of command-line arguments allowed remote code
+   execution during a recursive clone in conjunction with SSH URLs.
+
+ * CVE-2019-1351:
+   While the only permitted drive letters for physical drives on
+   Windows are letters of the US-English alphabet, this restriction
+   does not apply to virtual drives assigned via subst <letter>:
+   <path>. Git mistook such paths for relative paths, allowing writing
+   outside of the worktree while cloning.
+
+ * CVE-2019-1352:
+   Git was unaware of NTFS Alternate Data Streams, allowing files
+   inside the .git/ directory to be overwritten during a clone.
+
+ * CVE-2019-1353:
+   When running Git in the Windows Subsystem for Linux (also known as
+   "WSL") while accessing a working directory on a regular Windows
+   drive, none of the NTFS protections were active.
+
+ * CVE-2019-1354:
+   Filenames on Linux/Unix can contain backslashes. On Windows,
+   backslashes are directory separators. Git did not use to refuse to
+   write out tracked files with such filenames.
+
+ * CVE-2019-1387:
+   Recursive clones are currently affected by a vulnerability that is
+   caused by too-lax validation of submodule names, allowing very
+   targeted attacks via remote code execution in recursive clones.
+
+Credit for finding these vulnerabilities goes to Microsoft Security
+Response Center, in particular to Nicolas Joly. The `fast-import`
+fixes were provided by Jeff King, the other fixes by Johannes
+Schindelin with help from Garima Singh.

+=========================
+
+This release is to address a security issue: CVE-2020-11008
+
+Fixes since v2.17.4
+-------------------
+
+ * With a crafted URL that contains a newline or empty host, or lacks
+   a scheme, the credential helper machinery can be fooled into
+   providing credential information that is not appropriate for the
+   protocol in use and host being contacted.
+
+   Unlike the vulnerability CVE-2020-5260 fixed in v2.17.4, the
+   credentials are not for a host of the attacker's choosing; instead,
+   they are for some unspecified host (based on how the configured
+   credential helper handles an absent "host" parameter).
+
+   The attack has been made impossible by refusing to work with
+   under-specified credential patterns.
+
+Credit for finding the vulnerability goes to Carlo Arenas.

+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).

+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).
+

+Git 2.25.1 Release Notes
+========================
+
+Fixes since v2.25
+-----------------
+
+ * "git commit" gives output similar to "git status" when there is
+   nothing to commit, but without honoring the advise.statusHints
+   configuration variable, which has been corrected.
+
+ * has_object_file() said "no" given an object registered to the
+   system via pretend_object_file(), making it inconsistent with
+   read_object_file(), causing lazy fetch to attempt fetching an
+   empty tree from promisor remotes.
+
+ * The code that tries to skip over the entries for the paths in a
+   single directory using the cache-tree was not careful enough
+   against corrupt index file.
+
+ * Complete an update to tutorial that encourages "git switch" over
+   "git checkout" that was done only half-way.
+
+ * Reduce unnecessary round-trip when running "ls-remote" over the
+   stateless RPC mechanism.
+
+ * "git restore --staged" did not correctly update the cache-tree
+   structure, resulting in bogus trees to be written afterwards, which
+   has been corrected.
+
+ * The code recently added to move to the entry beyond the ones in the
+   same directory in the index in the sparse-cone mode did not count
+   the number of entries to skip over incorrectly, which has been
+   corrected.
+
+ * Work around test breakages caused by custom regex engine used in
+   libasan, when address sanitizer is used with more recent versions
+   of gcc and clang.
+
+ * "git fetch --refmap=" option has got a better documentation.
+
+ * Corner case bugs in "git clean" that stems from a (necessarily for
+   performance reasons) awkward calling convention in the directory
+   enumeration API has been corrected.
+
+ * "git grep --no-index" should not get affected by the contents of
+   the .gitmodules file but when "--recurse-submodules" is given or
+   the "submodule.recurse" variable is set, it did.  Now these
+   settings are ignored in the "--no-index" mode.
+
+ * Technical details of the bundle format has been documented.
+
+ * Unhelpful warning messages during documentation build have been
+   squelched.
+
+Also contains various documentation updates, code clean-ups and minor fixups.

+Git 2.25.2 Release Notes
+========================
+
+Fixes since v2.25.1
+-------------------
+
+ * Minor bugfixes to "git add -i" that has recently been rewritten in C.
+
+ * An earlier update to show the location of working tree in the error
+   message did not consider the possibility that a git command may be
+   run in a bare repository, which has been corrected.
+
+ * The "--recurse-submodules" option of various subcommands did not
+   work well when run in an alternate worktree, which has been
+   corrected.
+
+ * Running "git rm" on a submodule failed unnecessarily when
+   .gitmodules is only cache-dirty, which has been corrected.
+
+ * "git rebase -i" identifies existing commits in its todo file with
+   their abbreviated object name, which could become ambigous as it
+   goes to create new commits, and has a mechanism to avoid ambiguity
+   in the main part of its execution.  A few other cases however were
+   not covered by the protection against ambiguity, which has been
+   corrected.
+
+ * The index-pack code now diagnoses a bad input packstream that
+   records the same object twice when it is used as delta base; the
+   code used to declare a software bug when encountering such an
+   input, but it is an input error.
+
+ * The code to automatically shrink the fan-out in the notes tree had
+   an off-by-one bug, which has been killed.
+
+ * "git check-ignore" did not work when the given path is explicitly
+   marked as not ignored with a negative entry in the .gitignore file.
+
+ * The merge-recursive machinery failed to refresh the cache entry for
+   a merge result in a couple of places, resulting in an unnecessary
+   merge failure, which has been fixed.
+
+ * Fix for a bug revealed by a recent change to make the protocol v2
+   the default.
+
+ * "git merge signed-tag" while lacking the public key started to say
+   "No signature", which was utterly wrong.  This regression has been
+   reverted.
+
+ * MinGW's poll() emulation has been improved.
+
+ * "git show" and others gave an object name in raw format in its
+   error output, which has been corrected to give it in hex.
+
+ * Both "git ls-remote -h" and "git grep -h" give short usage help,
+   like any other Git subcommand, but it is not unreasonable to expect
+   that the former would behave the same as "git ls-remote --head"
+   (there is no other sensible behaviour for the latter).  The
+   documentation has been updated in an attempt to clarify this.
+
+Also contains various documentation updates, code clean-ups and minor fixups.

+Git 2.26 Release Notes
+======================
+
+Updates since v2.25
+-------------------
+
+Backward compatibility notes
+
+ * "git rebase" uses a different backend that is based on the 'merge'
+   machinery by default.  There are a few known differences in the
+   behaviour from the traditional machinery based on patch+apply.
+
+   If your workflow is negatively affected by this change, please
+   report it to git@vger.kernel.org so that we can take a look into
+   it.  After doing so, you can set the 'rebase.backend' configuration
+   variable to 'apply', in order to use the old default behaviour in
+   the meantime.
+
+
+UI, Workflows & Features
+
+ * Sample credential helper for using .netrc has been updated to work
+   out of the box.
+
+ * gpg.minTrustLevel configuration variable has been introduced to
+   tell various signature verification codepaths the required minimum
+   trust level.
+
+ * The command line completion (in contrib/) learned to complete
+   subcommands and arguments to "git worktree".
+
+ * Disambiguation logic to tell revisions and pathspec apart has been
+   tweaked so that backslash-escaped glob special characters do not
+   count in the "wildcards are pathspec" rule.
+
+ * One effect of specifying where the GIT_DIR is (either with the
+   environment variable, or with the "git --git-dir=<where> cmd"
+   option) is to disable the repository discovery.  This has been
+   placed a bit more stress in the documentation, as new users often
+   get confused.
+
+ * Two help messages given when "git add" notices the user gave it
+   nothing to add have been updated to use advise() API.
+
+ * A new version of fsmonitor-watchman hook has been introduced, to
+   avoid races.
+
+ * "git config" learned to show in which "scope", in addition to in
+   which file, each config setting comes from.
+
+ * The basic 7 colors learned the brighter counterparts
+   (e.g. "brightred").
+
+ * "git sparse-checkout" learned a new "add" subcommand.
+
+ * A configuration element used for credential subsystem can now use
+   wildcard pattern to specify for which set of URLs the entry
+   applies.
+
+ * "git clone --recurse-submodules --single-branch" now uses the same
+   single-branch option when cloning the submodules.
+
+ * "git rm" and "git stash" learns the new "--pathspec-from-file"
+   option.
+
+ * "git am --show-current-patch" is a way to show the piece of e-mail
+   for the stopped step, which is not suitable to directly feed "git
+   apply" (it is designed to be a good "git am" input).  It learned a
+   new option to show only the patch part.
+
+ * Handling of conflicting renames in merge-recursive have further
+   been made consistent with how existing codepaths try to mimic what
+   is done to add/add conflicts.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Tell .editorconfig that in this project, *.txt files are indented
+   with tabs.
+
+ * The test-lint machinery knew to check "VAR=VAL shell_function"
+   construct, but did not check "VAR= shell_function", which has been
+   corrected.
+
+ * Replace "git config --bool" calls with "git config --type=bool" in
+   sample templates.
+
+ * The effort to move "git-add--interactive" to C continues.
+
+ * Improve error message generation for "git submodule add".
+
+ * Preparation of test scripts for the day when the object names will
+   use SHA-256 continues.
+
+ * Warn programmers about pretend_object_file() that allows the code
+   to tentatively use in-core objects.
+
+ * The way "git pack-objects" reuses objects stored in existing pack
+   to generate its result has been improved.
+
+ * The transport protocol version 2 becomes the default one.
+
+ * Traditionally, we avoided threaded grep while searching in objects
+   (as opposed to files in the working tree) as accesses to the object
+   layer is not thread-safe.  This limitation is getting lifted.
+
+ * "git rebase -i" (and friends) used to unnecessarily check out the
+   tip of the branch to be rebased, which has been corrected.
+
+ * A low-level API function get_oid(), that accepts various ways to
+   name an object, used to issue end-user facing error messages
+   without l10n, which has been updated to be translatable.
+
+ * Unneeded connectivity check is now disabled in a partial clone when
+   fetching into it.
+
+ * Some rough edges in the sparse-checkout feature, especially around
+   the cone mode, have been cleaned up.
+
+ * The diff-* plumbing family of subcommands now pay attention to the
+   diff.wsErrorHighlight configuration, which has been ignored before;
+   this allows "git add -p" to also show the whitespace problems to
+   the end user.
+
+ * Some codepaths were given a repository instance as a parameter to
+   work in the repository, but passed the_repository instance to its
+   callees, which has been cleaned up (somewhat).
+
+ * Memory footprint and performance of "git name-rev" has been
+   improved.
+
+ * The object reachability bitmap machinery and the partial cloning
+   machinery were not prepared to work well together, because some
+   object-filtering criteria that partial clones use inherently rely
+   on object traversal, but the bitmap machinery is an optimization
+   to bypass that object traversal.  There however are some cases
+   where they can work together, and they were taught about them.
+
+ * "git rebase" has learned to use the merge backend (i.e. the
+   machinery that drives "rebase -i") by default, while allowing
+   "--apply" option to use the "apply" backend (e.g. the moral
+   equivalent of "format-patch piped to am").  The rebase.backend
+   configuration variable can be set to customize.
+
+ * Underlying machinery of "git bisect--helper" is being refactored
+   into pieces that are more easily reused.
+
+
+Fixes since v2.25
+-----------------
+
+ * "git commit" gives output similar to "git status" when there is
+   nothing to commit, but without honoring the advise.statusHints
+   configuration variable, which has been corrected.
+
+ * has_object_file() said "no" given an object registered to the
+   system via pretend_object_file(), making it inconsistent with
+   read_object_file(), causing lazy fetch to attempt fetching an
+   empty tree from promisor remotes.
+
+ * Complete an update to tutorial that encourages "git switch" over
+   "git checkout" that was done only half-way.
+
+ * C pedantry ;-) fix.
+
+ * The code that tries to skip over the entries for the paths in a
+   single directory using the cache-tree was not careful enough
+   against corrupt index file.
+
+ * Reduce unnecessary round-trip when running "ls-remote" over the
+   stateless RPC mechanism.
+
+ * "git restore --staged" did not correctly update the cache-tree
+   structure, resulting in bogus trees to be written afterwards, which
+   has been corrected.
+
+ * The code recently added to move to the entry beyond the ones in the
+   same directory in the index in the sparse-cone mode did not count
+   the number of entries to skip over incorrectly, which has been
+   corrected.
+
+ * Rendering by "git log --graph" of ancestry lines leading to a merge
+   commit were made suboptimal to waste vertical space a bit with a
+   recent update, which has been corrected.
+
+ * Work around test breakages caused by custom regex engine used in
+   libasan, when address sanitizer is used with more recent versions
+   of gcc and clang.
+
+ * Minor bugfixes to "git add -i" that has recently been rewritten in C.
+
+ * "git fetch --refmap=" option has got a better documentation.
+
+ * "git checkout X" did not correctly fail when X is not a local
+   branch but could name more than one remote-tracking branches
+   (i.e. to be dwimmed as the starting point to create a corresponding
+   local branch), which has been corrected.
+   (merge fa74180d08 am/checkout-file-and-ref-ref-ambiguity later to maint).
+
+ * Corner case bugs in "git clean" that stems from a (necessarily for
+   performance reasons) awkward calling convention in the directory
+   enumeration API has been corrected.
+
+ * A fetch that is told to recursively fetch updates in submodules
+   inevitably produces reams of output, and it becomes hard to spot
+   error messages.  The command has been taught to enumerate
+   submodules that had errors at the end of the operation.
+   (merge 0222540827 es/fetch-show-failed-submodules-atend later to maint).
+
+ * The "--recurse-submodules" option of various subcommands did not
+   work well when run in an alternate worktree, which has been
+   corrected.
+
+ * Futureproofing a test not to depend on the current implementation
+   detail.
+
+ * Running "git rm" on a submodule failed unnecessarily when
+   .gitmodules is only cache-dirty, which has been corrected.
+
+ * C pedantry ;-) fix.
+
+ * "git grep --no-index" should not get affected by the contents of
+   the .gitmodules file but when "--recurse-submodules" is given or
+   the "submodule.recurse" variable is set, it did.  Now these
+   settings are ignored in the "--no-index" mode.
+
+ * Technical details of the bundle format has been documented.
+
+ * Unhelpful warning messages during documentation build have been squelched.
+
+ * "git rebase -i" identifies existing commits in its todo file with
+   their abbreviated object name, which could become ambiguous as it
+   goes to create new commits, and has a mechanism to avoid ambiguity
+   in the main part of its execution.  A few other cases however were
+   not covered by the protection against ambiguity, which has been
+   corrected.
+
+ * Allow the rebase.missingCommitsCheck configuration to kick in when
+   "rebase --edit-todo" and "rebase --continue" restarts the procedure.
+   (merge 5a5445d878 ag/edit-todo-drop-check later to maint).
+
+ * The way "git submodule status" reports an initialized but not yet
+   populated submodule has not been reimplemented correctly when a
+   part of the "git submodule" command was rewritten in C, which has
+   been corrected.
+   (merge f38c92452d pk/status-of-uncloned-submodule later to maint).
+
+ * The code to automatically shrink the fan-out in the notes tree had
+   an off-by-one bug, which has been killed.
+
+ * The index-pack code now diagnoses a bad input packstream that
+   records the same object twice when it is used as delta base; the
+   code used to declare a software bug when encountering such an
+   input, but it is an input error.
+
+
+ * The code to compute the commit-graph has been taught to use a more
+   robust way to tell if two object directories refer to the same
+   thing.
+   (merge a7df60cac8 tb/commit-graph-object-dir later to maint).
+
+ * "git remote rename X Y" needs to adjust configuration variables
+   (e.g. branch.<name>.remote) whose value used to be X to Y.
+   branch.<name>.pushRemote is now also updated.
+
+ * Update to doc-diff.
+
+ * Doc markup fix.
+
+ * "git check-ignore" did not work when the given path is explicitly
+   marked as not ignored with a negative entry in the .gitignore file.
+
+ * The merge-recursive machinery failed to refresh the cache entry for
+   a merge result in a couple of places, resulting in an unnecessary
+   merge failure, which has been fixed.
+
+ * Fix for a bug revealed by a recent change to make the protocol v2
+   the default.
+
+ * In rare cases "git worktree add <path>" could think that <path>
+   was already a registered worktree even when it wasn't and refuse
+   to add the new worktree. This has been corrected.
+   (merge bb69b3b009 es/worktree-avoid-duplication-fix later to maint).
+
+ * "git push" should stop from updating a branch that is checked out
+   when receive.denyCurrentBranch configuration is set, but it failed
+   to pay attention to checkouts in secondary worktrees.  This has
+   been corrected.
+   (merge 4d864895a2 hv/receive-denycurrent-everywhere later to maint).
+
+ * "git rebase BASE BRANCH" rebased/updated the tip of BRANCH and
+   checked it out, even when the BRANCH is checked out in a different
+   worktree.  This has been corrected.
+   (merge b5cabb4a96 es/do-not-let-rebase-switch-to-protected-branch later to maint).
+
+ * "git describe" in a repository with multiple root commits sometimes
+   gave up looking for the best tag to describe a given commit with
+   too early, which has been adjusted.
+
+ * "git merge signed-tag" while lacking the public key started to say
+   "No signature", which was utterly wrong.  This regression has been
+   reverted.
+
+ * MinGW's poll() emulation has been improved.
+
+ * "git show" and others gave an object name in raw format in its
+   error output, which has been corrected to give it in hex.
+
+ * "git fetch" over HTTP walker protocol did not show any progress
+   output.  We inherently do not know how much work remains, but still
+   we can show something not to bore users.
+   (merge 7655b4119d rs/show-progress-in-dumb-http-fetch later to maint).
+
+ * Both "git ls-remote -h" and "git grep -h" give short usage help,
+   like any other Git subcommand, but it is not unreasonable to expect
+   that the former would behave the same as "git ls-remote --head"
+   (there is no other sensible behaviour for the latter).  The
+   documentation has been updated in an attempt to clarify this.
+
+ * Other code cleanup, docfix, build fix, etc.
