+Git v2.17.6 Release Notes
+=========================
+
+This release addresses the security issues CVE-2021-21300.
+
+Fixes since v2.17.5
+-------------------
+
+ * CVE-2021-21300:
+   On case-insensitive file systems with support for symbolic links,
+   if Git is configured globally to apply delay-capable clean/smudge
+   filters (such as Git LFS), Git could be fooled into running
+   remote code during a clone.
+
+Credit for finding and fixing this vulnerability goes to Matheus
+Tavares, helped by Johannes Schindelin.

+Git v2.30.1 Release Notes
+=========================
+
+This release is primarily to merge fixes accumulated on the 'master'
+front to prepare for 2.31 release that are still relevant to 2.30.x
+maintenance track.
+
+Fixes since v2.30
+-----------------
+
+ * "git fetch --recurse-submodules" failed to update a submodule
+   when it has an uninitialized (hence of no interest to the user)
+   sub-submodule, which has been corrected.
+
+ * Command line error of "git rebase" are diagnosed earlier.
+
+ * "git stash" did not work well in a sparsely checked out working
+   tree.
+
+ * Some tests expect that "ls -l" output has either '-' or 'x' for
+   group executable bit, but setgid bit can be inherited from parent
+   directory and make these fields 'S' or 's' instead, causing test
+   failures.
+
+ * "git for-each-repo --config=<var> <cmd>" should not run <cmd> for
+   any repository when the configuration variable <var> is not defined
+   even once.
+
+ * "git mergetool --tool-help" was broken in 2.29 and failed to list
+   all the available tools.
+
+ * Fix for procedure to building CI test environment for mac.
+
+ * Newline characters in the host and path part of git:// URL are
+   now forbidden.
+
+ * When more than one commit with the same patch ID appears on one
+   side, "git log --cherry-pick A...B" did not exclude them all when a
+   commit with the same patch ID appears on the other side.  Now it
+   does.
+
+ * Documentation for "git fsck" lost stale bits that has become
+   incorrect.
+
+ * Doc for packfile URI feature has been clarified.
+
+ * The implementation of "git branch --sort" wrt the detached HEAD
+   display has always been hacky, which has been cleaned up.
+
+ * Our setting of GitHub CI test jobs were a bit too eager to give up
+   once there is even one failure found.  Tweak the knob to allow
+   other jobs keep running even when we see a failure, so that we can
+   find more failures in a single run.
+
+Also contains minor documentation updates and code clean-ups.

+Git 2.31 Release Notes
+======================
+
+Updates since v2.30
+-------------------
+
+Backward incompatible and other important changes
+
+ * The "pack-redundant" command, which has been left stale with almost
+   unusable performance issues, now warns loudly when it gets used, as
+   we no longer want to recommend its use (instead just "repack -d"
+   instead).
+
+ * The development community has adopted Contributor Covenant v2.0 to
+   update from v1.4 that we have been using.
+
+ * The support for deprecated PCRE1 library has been dropped.
+
+ * Fixes for CVE-2021-21300 in Git 2.30.2 (and earlier) is included.
+
+
+UI, Workflows & Features
+
+ * The "--format=%(trailers)" mechanism gets enhanced to make it
+   easier to design output for machine consumption.
+
+ * When a user does not tell "git pull" to use rebase or merge, the
+   command gives a loud message telling a user to choose between
+   rebase or merge but creates a merge anyway, forcing users who would
+   want to rebase to redo the operation.  Fix an early part of this
+   problem by tightening the condition to give the message---there is
+   no reason to stop or force the user to choose between rebase or
+   merge if the history fast-forwards.
+
+ * The configuration variable 'core.abbrev' can be set to 'no' to
+   force no abbreviation regardless of the hash algorithm.
+
+ * "git rev-parse" can be explicitly told to give output as absolute
+   or relative path with the `--path-format=(absolute|relative)` option.
+
+ * Bash completion (in contrib/) update to make it easier for
+   end-users to add completion for their custom "git" subcommands.
+
+ * "git maintenance" learned to drive scheduled maintenance on
+   platforms whose native scheduling methods are not 'cron'.
+
+ * After expiring a reflog and making a single commit, the reflog for
+   the branch would record a single entry that knows both @{0} and
+   @{1}, but we failed to answer "what commit were we on?", i.e. @{1}
+
+ * "git bundle" learns "--stdin" option to read its refs from the
+   standard input.  Also, it now does not lose refs whey they point
+   at the same object.
+
+ * "git log" learned a new "--diff-merges=<how>" option.
+
+ * "git ls-files" can and does show multiple entries when the index is
+   unmerged, which is a source for confusion unless -s/-u option is in
+   use.  A new option --deduplicate has been introduced.
+
+ * `git worktree list` now annotates worktrees as prunable, shows
+   locked and prunable attributes in --porcelain mode, and gained
+   a --verbose option.
+
+ * "git clone" tries to locally check out the branch pointed at by
+   HEAD of the remote repository after it is done, but the protocol
+   did not convey the information necessary to do so when copying an
+   empty repository.  The protocol v2 learned how to do so.
+
+ * There are other ways than ".." for a single token to denote a
+   "commit range", namely "<rev>^!" and "<rev>^-<n>", but "git
+   range-diff" did not understand them.
+
+ * The "git range-diff" command learned "--(left|right)-only" option
+   to show only one side of the compared range.
+
+ * "git mergetool" feeds three versions (base, local and remote) of
+   a conflicted path unmodified.  The command learned to optionally
+   prepare these files with unconflicted parts already resolved.
+
+ * The .mailmap is documented to be read only from the root level of a
+   working tree, but a stray file in a bare repository also was read
+   by accident, which has been corrected.
+
+ * "git maintenance" tool learned a new "pack-refs" maintenance task.
+
+ * The error message given when a configuration variable that is
+   expected to have a boolean value has been improved.
+
+ * Signed commits and tags now allow verification of objects, whose
+   two object names (one in SHA-1, the other in SHA-256) are both
+   signed.
+
+ * "git rev-list" command learned "--disk-usage" option.
+
+ * "git {diff,log} --{skip,rotate}-to=<path>" allows the user to
+   discard diff output for early paths or move them to the end of the
+   output.
+
+ * "git difftool" learned "--skip-to=<path>" option to restart an
+   interrupted session from an arbitrary path.
+
+ * "git grep" has been tweaked to be limited to the sparse checkout
+   paths.
+
+ * "git rebase --[no-]fork-point" gained a configuration variable
+   rebase.forkPoint so that users do not have to keep specifying a
+   non-default setting.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * A 3-year old test that was not testing anything useful has been
+   corrected.
+
+ * Retire more names with "sha1" in it.
+
+ * The topological walk codepath is covered by new trace2 stats.
+
+ * Update the Code-of-conduct to version 2.0 from the upstream (we've
+   been using version 1.4).
+
+ * "git mktag" validates its input using its own rules before writing
+   a tag object---it has been updated to share the logic with "git
+   fsck".
+
+ * Two new ways to feed configuration variable-value pairs via
+   environment variables have been introduced, and the way
+   GIT_CONFIG_PARAMETERS encodes variable/value pairs has been tweaked
+   to make it more robust.
+
+ * Tests have been updated so that they do not to get affected by the
+   name of the default branch "git init" creates.
+
+ * "git fetch" learns to treat ref updates atomically in all-or-none
+   fashion, just like "git push" does, with the new "--atomic" option.
+
+ * The peel_ref() API has been replaced with peel_iterated_oid().
+
+ * The .use_shell flag in struct child_process that is passed to
+   run_command() API has been clarified with a bit more documentation.
+
+ * Document, clean-up and optimize the code around the cache-tree
+   extension in the index.
+
+ * The ls-refs protocol operation has been optimized to narrow the
+   sub-hierarchy of refs/ it walks to produce response.
+
+ * When removing many branches and tags, the code used to do so one
+   ref at a time.  There is another API it can use to delete multiple
+   refs, and it makes quite a lot of performance difference when the
+   refs are packed.
+
+ * The "pack-objects" command needs to iterate over all the tags when
+   automatic tag following is enabled, but it actually iterated over
+   all refs and then discarded everything outside "refs/tags/"
+   hierarchy, which was quite wasteful.
+
+ * A perf script was made more portable.
+
+ * Our setting of GitHub CI test jobs were a bit too eager to give up
+   once there is even one failure found.  Tweak the knob to allow
+   other jobs keep running even when we see a failure, so that we can
+   find more failures in a single run.
+
+ * We've carried compatibility codepaths for compilers without
+   variadic macros for quite some time, but the world may be ready for
+   them to be removed.  Force compilation failure on exotic platforms
+   where variadic macros are not available to find out who screams in
+   such a way that we can easily revert if it turns out that the world
+   is not yet ready.
+
+ * Code clean-up to ensure our use of hashtables using object names as
+   keys use the "struct object_id" objects, not the raw hash values.
+
+ * Lose the debugging aid that may have been useful in the past, but
+   no longer is, in the "grep" codepaths.
+
+ * Some pretty-format specifiers do not need the data in commit object
+   (e.g. "%H"), but we were over-eager to load and parse it, which has
+   been made even lazier.
+
+ * Get rid of "GETTEXT_POISON" support altogether, which may or may
+   not be controversial.
+
+ * Introduce an on-disk file to record revindex for packdata, which
+   traditionally was always created on the fly and only in-core.
+
+ * The commit-graph learned to use corrected commit dates instead of
+   the generation number to help topological revision traversal.
+
+ * Piecemeal of rewrite of "git bisect" in C continues.
+
+ * When a pager spawned by us exited, the trace log did not record its
+   exit status correctly, which has been corrected.
+
+ * Removal of GIT_TEST_GETTEXT_POISON continues.
+
+ * The code to implement "git merge-base --independent" was poorly
+   done and was kept from the very beginning of the feature.
+
+ * Preliminary changes to fsmonitor integration.
+
+ * Performance improvements for rename detection.
+
+ * The common code to deal with "chunked file format" that is shared
+   by the multi-pack-index and commit-graph files have been factored
+   out, to help codepaths for both filetypes to become more robust.
+
+ * The approach to "fsck" the incoming objects in "index-pack" is
+   attractive for performance reasons (we have them already in core,
+   inflated and ready to be inspected), but fundamentally cannot be
+   applied fully when we receive more than one pack stream, as a tree
+   object in one pack may refer to a blob object in another pack as
+   ".gitmodules", when we want to inspect blobs that are used as
+   ".gitmodules" file, for example.  Teach "index-pack" to emit
+   objects that must be inspected later and check them in the calling
+   "fetch-pack" process.
+
+ * The logic to handle "trailer" related placeholders in the
+   "--format=" mechanisms in the "log" family and "for-each-ref"
+   family is getting unified.
+
+ * Raise the buffer size used when writing the index file out from
+   (obviously too small) 8kB to (clearly sufficiently large) 128kB.
+
+ * It is reported that open() on some platforms (e.g. macOS Big Sur)
+   can return EINTR even though our timers are set up with SA_RESTART.
+   A workaround has been implemented and enabled for macOS to rerun
+   open() transparently from the caller when this happens.
+
+
+Fixes since v2.30
+-----------------
+
+ * Diagnose command line error of "git rebase" early.
+
+ * Clean up option descriptions in "git cmd --help".
+
+ * "git stash" did not work well in a sparsely checked out working
+   tree.
+
+ * Some tests expect that "ls -l" output has either '-' or 'x' for
+   group executable bit, but setgid bit can be inherited from parent
+   directory and make these fields 'S' or 's' instead, causing test
+   failures.
+
+ * "git for-each-repo --config=<var> <cmd>" should not run <cmd> for
+   any repository when the configuration variable <var> is not defined
+   even once.
+
+ * Fix 2.29 regression where "git mergetool --tool-help" fails to list
+   all the available tools.
+
+ * Fix for procedure to building CI test environment for mac.
+
+ * The implementation of "git branch --sort" wrt the detached HEAD
+   display has always been hacky, which has been cleaned up.
+
+ * Newline characters in the host and path part of git:// URL are
+   now forbidden.
+
+ * "git diff" showed a submodule working tree with untracked cruft as
+   "Submodule commit <objectname>-dirty", but a natural expectation is
+   that the "-dirty" indicator would align with "git describe --dirty",
+   which does not consider having untracked files in the working tree
+   as source of dirtiness.  The inconsistency has been fixed.
+
+ * When more than one commit with the same patch ID appears on one
+   side, "git log --cherry-pick A...B" did not exclude them all when a
+   commit with the same patch ID appears on the other side.  Now it
+   does.
+
+ * Documentation for "git fsck" lost stale bits that has become
+   incorrect.
+
+ * Doc fix for packfile URI feature.
+
+ * When "git rebase -i" processes "fixup" insn, there is no reason to
+   clean up the commit log message, but we did the usual stripspace
+   processing.  This has been corrected.
+   (merge f7d42ceec5 js/rebase-i-commit-cleanup-fix later to maint).
+
+ * Fix in passing custom args from "git clone" to "upload-pack" on the
+   other side.
+   (merge ad6b5fefbd jv/upload-pack-filter-spec-quotefix later to maint).
+
+ * The command line completion (in contrib/) completed "git branch -d"
+   with branch names, but "git branch -D" offered tagnames in addition,
+   which has been corrected.  "git branch -M" had the same problem.
+   (merge 27dc071b9a jk/complete-branch-force-delete later to maint).
+
+ * When commands are started from a subdirectory, they may have to
+   compare the path to the subdirectory (called prefix and found out
+   from $(pwd)) with the tracked paths.  On macOS, $(pwd) and
+   readdir() yield decomposed path, while the tracked paths are
+   usually normalized to the precomposed form, causing mismatch.  This
+   has been fixed by taking the same approach used to normalize the
+   command line arguments.
+   (merge 5c327502db tb/precompose-prefix-too later to maint).
+
+ * Even though invocations of "die()" were logged to the trace2
+   system, "BUG()"s were not, which has been corrected.
+   (merge 0a9dde4a04 jt/trace2-BUG later to maint).
+
+ * "git grep --untracked" is meant to be "let's ALSO find in these
+   files on the filesystem" when looking for matches in the working
+   tree files, and does not make any sense if the primary search is
+   done against the index, or the tree objects.  The "--cached" and
+   "--untracked" options have been marked as mutually incompatible.
+   (merge 0c5d83b248 mt/grep-cached-untracked later to maint).
+
+ * Fix "git fsck --name-objects" which apparently has not been used by
+   anybody who is motivated enough to report breakage.
+   (merge e89f89361c js/fsck-name-objects-fix later to maint).
+
+ * Avoid individual tests in t5411 from getting affected by each other
+   by forcing them to use separate output files during the test.
+   (merge 822ee894f6 jx/t5411-unique-filenames later to maint).
+
+ * Test to make sure "git rev-parse one-thing one-thing" gives
+   the same thing twice (when one-thing is --since=X).
+   (merge a5cdca4520 ew/rev-parse-since-test later to maint).
+
+ * When certain features (e.g. grafts) used in the repository are
+   incompatible with the use of the commit-graph, we used to silently
+   turned commit-graph off; we now tell the user what we are doing.
+   (merge c85eec7fc3 js/commit-graph-warning later to maint).
+
+ * Objects that lost references can be pruned away, even when they
+   have notes attached to it (and these notes will become dangling,
+   which in turn can be pruned with "git notes prune").  This has been
+   clarified in the documentation.
+   (merge fa9ab027ba mz/doc-notes-are-not-anchors later to maint).
+
+ * The error codepath around the "--temp/--prefix" feature of "git
+   checkout-index" has been improved.
+   (merge 3f7ba60350 mt/checkout-index-corner-cases later to maint).
+
+ * The "git maintenance register" command had trouble registering bare
+   repositories, which had been corrected.
+
+ * A handful of multi-word configuration variable names in
+   documentation that are spelled in all lowercase have been corrected
+   to use the more canonical camelCase.
+   (merge 7dd0eaa39c dl/doc-config-camelcase later to maint).
+
+ * "git push $there --delete ''" should have been diagnosed as an
+   error, but instead turned into a matching push, which has been
+   corrected.
+   (merge 20e416409f jc/push-delete-nothing later to maint).
+
+ * Test script modernization.
+   (merge 488acf15df sv/t7001-modernize later to maint).
+
+ * An under-allocation for the untracked cache data has been corrected.
+   (merge 6347d649bc jh/untracked-cache-fix later to maint).
+
+ * Other code cleanup, docfix, build fix, etc.
+   (merge e3f5da7e60 sg/t7800-difftool-robustify later to maint).
+   (merge 9d336655ba js/doc-proto-v2-response-end later to maint).
+   (merge 1b5b8cf072 jc/maint-column-doc-typofix later to maint).
+   (merge 3a837b58e3 cw/pack-config-doc later to maint).
+   (merge 01168a9d89 ug/doc-commit-approxidate later to maint).
+   (merge b865734760 js/params-vs-args later to maint).
