We are at -rc2 now.  A few more topics are now in 'next' but it is
not a big deal anyway, as they are not about any regression fixes
and will not go anywhere during the prerelease freeze.

Here are the topics that have been cooking in my tree.  Commits
prefixed with '+' are in 'next' (being in 'next' is a sign that a
topic is stable enough to be used and are candidate to be in a
future release).  Commits prefixed with '-' are only in 'seen',
which means nothing more than that I have found them of interest for
some reason (like "it may have hard-to-resolve conflicts with
another topic already in flight" or "this may turn out to be
useful").  Do not read too much into a topic being in (or not in)
'seen'.  The ones marked with '.' do not appear in any of the
integration branches, but I am still holding onto them.

Copies of the source code to Git live in many repositories, and the
following is a list of the ones I push into or their mirrors.  Some
repositories have only a subset of branches.

With maint, master, next, seen, todo:

	git://git.kernel.org/pub/scm/git/git.git/
	git://repo.or.cz/alt-git.git/
	https://kernel.googlesource.com/pub/scm/git/git/
	https://github.com/git/git/
	https://gitlab.com/git-vcs/git/

With all the integration branches and topics broken out:

	https://github.com/gitster/git/

Even though the preformatted documentation in HTML and man format
are not sources, they are published in these repositories for
convenience (replace "htmldocs" with "manpages" for the manual
pages):

  (merged to 'next' on 2022-01-16 at 1aeeab2aa6)

 the fallback implementation of uncompress2 we ship.

 FreeBSD 13.0 headers have unconditional dependency on C11 language
 features, and adding -std=gnu99 to DEVELOPER_CFLAGS would just
 break the developer build.

 corrected.

 before other args, which has been corrected.

 . http-backend: give a hint that web browser access is not supported

 When the http-backend program, which is the server-side component
 for the smart HTTP transport, sends a "404 Not found" error, we
 deliberately did not say anything to the requesting client.  We now
 send a message back to the browser to tell the user that they do
 not want to visit the URL via their browser, instead of a totally
 blank page.

 + fetch --negotiate-only: do not update submodules
 + fetch: skip tasks related to fetching objects
 + fetch: use goto cleanup in cmd_fetch()

 "git fetch --negotiate-only" is an internal command used by "git
 push" to figure out which part of our history is missing from the
 other side.  It should never recurse into submodules even when
 fetch.recursesubmodules configuration variable is set, nor it
 should trigger "gc".  The code has been tightened up to ensure it
 only does common ancestry discovery and nothing else.

 - refs: demonstrate excessive execution of the reference-transaction hook
 - refs: allow skipping the reference-transaction hook
 - refs: allow passing flags when beginning transactions
 - refs: extract packed_refs_delete_refs() to allow control of transaction

 Because a deletion of ref would need to remove it from both the
 loose ref store and the packed ref store, a delete-ref operation
 that logically removes one ref may end up invoking ref-transaction
 hook twice, which has been corrected.

* ab/grep-patterntype (2022-01-18) 10 commits
 - grep.[ch]: remove GREP_PATTERN_TYPE_UNSPECIFIED
 - grep: simplify config parsing and option parsing
 - grep.c: do "if (bool && memchr())" not "if (memchr() && bool)"
 - grep.h: make "grep_opt.pattern_type_option" use its enum
 - grep API: call grep_config() after grep_init()
 - grep.c: don't pass along NULL callback value
 - built-ins: trust the "prefix" from run_builtin()
 - grep tests: add missing "grep.patternType" config tests

 Some code clean-up in the "git grep" machinery.

 Looking good, except for the last two steps.

* js/use-builtin-add-i (2021-12-01) 2 commits
 - add -i: default to the built-in implementation
 - t2016: require the PERL prereq only when necessary

 "git add -i" was rewritten in C some time ago and has been in
 testing; the reimplementation is now exposed to general public by
 default.

 On hold.
 There are known breakages on macOS.

 The conditional inclusion mechanism of configuration files using
 "[includeIf <condition>]" learns to base its decision on the
 URL of the remote repository the repository interacts with.
