+Git 2.22.1 Release Notes
+========================
+
+Fixes since v2.22
+-----------------
+
+ * A relative pathname given to "git init --template=<path> <repo>"
+   ought to be relative to the directory "git init" gets invoked in,
+   but it instead was made relative to the repository, which has been
+   corrected.
+
+ * "git worktree add" used to fail when another worktree connected to
+   the same repository was corrupt, which has been corrected.
+
+ * The ownership rule for the file descriptor to fast-import remote
+   backend was mixed up, leading to unrelated file descriptor getting
+   closed, which has been fixed.
+
+ * "git update-server-info" used to leave stale packfiles in its
+   output, which has been corrected.
+
+ * The server side support for "git fetch" used to show incorrect
+   value for the HEAD symbolic ref when the namespace feature is in
+   use, which has been corrected.
+
+ * "git am -i --resolved" segfaulted after trying to see a commit as
+   if it were a tree, which has been corrected.
+
+ * "git bundle verify" needs to see if prerequisite objects exist in
+   the receiving repository, but the command did not check if we are
+   in a repository upfront, which has been corrected.
+
+ * "git merge --squash" is designed to update the working tree and the
+   index without creating the commit, and this cannot be countermanded
+   by adding the "--commit" option; the command now refuses to work
+   when both options are given.
+
+ * The data collected by fsmonitor was not properly written back to
+   the on-disk index file, breaking t7519 tests occasionally, which
+   has been corrected.
+
+ * Update to Unicode 12.1 width table.
+
+ * The command line to invoke a "git cat-file" command from inside
+   "git p4" was not properly quoted to protect a caret and running a
+   broken command on Windows, which has been corrected.
+
+ * "git request-pull" learned to warn when the ref we ask them to pull
+   from in the local repository and in the published repository are
+   different.
+
+ * When creating a partial clone, the object filtering criteria is
+   recorded for the origin of the clone, but this incorrectly used a
+   hardcoded name "origin" to name that remote; it has been corrected
+   to honor the "--origin <name>" option.
+
+ * "git fetch" into a lazy clone forgot to fetch base objects that are
+   necessary to complete delta in a thin packfile, which has been
+   corrected.
+
+ * The filter_data used in the list-objects-filter (which manages a
+   lazily sparse clone repository) did not use the dynamic array API
+   correctly---'nr' is supposed to point at one past the last element
+   of the array in use.  This has been corrected.
+
+ * The description about slashes in gitignore patterns (used to
+   indicate things like "anchored to this level only" and "only
+   matches directories") has been revamped.
+
+ * The URL decoding code has been updated to avoid going past the end
+   of the string while parsing %-<hex>-<hex> sequence.
+
+ * The list of for-each like macros used by clang-format has been
+   updated.
+
+ * "git push --atomic" that goes over the transport-helper (namely,
+   the smart http transport) failed to prevent refs to be pushed when
+   it can locally tell that one of the ref update will fail without
+   having to consult the other end, which has been corrected.
+
+ * "git clean" silently skipped a path when it cannot lstat() it; now
+   it gives a warning.
+
+ * A codepath that reads from GPG for signed object verification read
+   past the end of allocated buffer, which has been fixed.
+
+ * "git rm" to resolve a conflicted path leaked an internal message
+   "needs merge" before actually removing the path, which was
+   confusing.  This has been corrected.
+
+ * The "git clone" documentation refers to command line options in its
+   description in the short form; they have been replaced with long
+   forms to make them more recognisable.
+
+ * The configuration variable rebase.rescheduleFailedExec should be
+   effective only while running an interactive rebase and should not
+   affect anything when running a non-interactive one, which was not
+   the case.  This has been corrected.
+
+ * "git submodule foreach" did not protect command line options passed
+   to the command to be run in each submodule correctly, when the
+   "--recursive" option was in use.
+
+ * Use "Erase in Line" CSI sequence that is already used in the editor
+   support to clear cruft in the progress output.
+
+ * The codepath to compute delta islands used to spew progress output
+   without giving the callers any way to squelch it, which has been
+   fixed.
+
+ * The code to parse scaled numbers out of configuration files has
+   been made more robust and also easier to follow.
+
+ * An incorrect list of options was cached after command line
+   completion failed (e.g. trying to complete a command that requires
+   a repository outside one), which has been corrected.
+
+ * "git rebase --abort" used to leave refs/rewritten/ when concluding
+   "git rebase -r", which has been corrected.
+
+ * "git stash show 23" used to work, but no more after getting
+   rewritten in C; this regression has been corrected.
+
+ * "git interpret-trailers" always treated '#' as the comment
+   character, regardless of core.commentChar setting, which has been
+   corrected.
+
+ * Code clean-up to avoid signed integer overlaps during binary search.
+
+ * "git checkout -p" needs to selectively apply a patch in reverse,
+   which did not work well.
+
+ * The commit-graph file is now part of the "files that the runtime
+   may keep open file descriptors on, all of which would need to be
+   closed when done with the object store", and the file descriptor to
+   an existing commit-graph file now is closed before "gc" finalizes a
+   new instance to replace it.
+
+ * Code restructuring during 2.20 period broke fetching tags via
+   "import" based transports.
+
+ * We have been trying out a few language features outside c89; the
+   coding guidelines document did not talk about them and instead had
+   a blanket ban against them.
+
+ * The internal diff machinery can be made to read out of bounds while
+   looking for --funcion-context line in a corner case, which has been
+   corrected.
+
+Also contains various documentation updates, code clean-ups and minor fixups.
