What's cooking in git.git (Jan 2023, #06; Sun, 22)
--------------------------------------------------

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', and aren't
considered "accepted" at all.  A topic without enough support may be
discarded after a long period of no activity.

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):

	git://git.kernel.org/pub/scm/git/git-htmldocs.git/
	https://github.com/gitster/git-htmldocs.git/

Release tarballs are available at:

 - rebase: put rebase_options initialization in single place
 - rebase: fix formatting of rebase --reapply-cherry-picks option in docs
 - rebase: clarify the OPT_CMDMODE incompatibilities

 - rebase: remove --allow-empty-message from incompatible opts
 - rebase: flag --apply and --merge as incompatible
 - rebase: mark --update-refs as requiring the merge backend

 The "--update-refs" feature of "git rebase" requires the use of the
 merge backend, while "--whitespace=fix" feature does not work with
 the said backend.  Notice the combination and error out, instead of
 silently ignoring one of the features requested.

 retain the old behaviour.
