Subject: What's cooking in git.git (Feb 2023, #03; Tue, 14)

From: Junio C Hamano <[email-masked]>
Date: Tue, 14 Feb 2023 10:05:19 -0800

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.

There are security releases, ranging from 2.30.8 to 2.39.2.  The
fixes in these releases have already been integrated to the 'master'
branch as well.

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:

 setting pull.rebase=true, but these days pull.rebase=merges may be
