Subject: What's cooking in git.git (Mar 2026, #08)

From: Junio C Hamano <[email-masked]>
Date: Sat, 21 Mar 2026 23:46:59 -0700

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 is a candidate to be in a
future release).  Commits prefixed with '-' are only in 'seen', and
aren't considered "accepted" at all and may be annotated with a URL
to a message that raises issues but they are by no means exhaustive.
A topic without enough support may be discarded after a long period
of no activity (of course they can be resubmitted when new interests
arise).

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-scm/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/

 - sideband: delay sanitizing by default to Git v3.0
 - Merge branch 'jc/neuter-sideband-fixup' into jc/neuter-sideband-post-3.0
 (this branch uses jc/neuter-sideband-fixup.)

 The final step, split from earlier attempt by Dscho, to loosen the
 sideband restriction for now and tighten later at Git v3.0 boundary.

 On hold, until jc/neuter-sideband-fixup cooks long enough in 'next'.

 was not propagated properly to child "git fetch" processes, which
 has been corrected.

 configuration variable.

 user asks for help, ensuring that scripts using the recommended `eval`
