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.

  CodingGuidelines: spell out post-C89 rules

+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.
+
+Also contains various documentation updates and code clean-ups.
