What's cooking in git.git (May 2024, #03; Mon, 6)
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 and may be annotated with an URL to a message that raises issues but they are no means exhaustive. A topic without enough support may be discarded after a long period of no activity (of course they can be resubmit 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/

Release tarballs are available at:

. builtin/shortlog: don't set up revisions without repo
. builtin/diff: explicitly set hash algo when there is no repo . builtin/bundle: abort "verify" early when there is no repository . builtin/blame: don't access potentially unitialized the_hash_algo . builtin/rev-parse: allow shortening to more than 40 hex characters . remote-curl: fix parsing of detached SHA256 heads

Before discovering the repository details, We used to assume SHA-1 as the "default" hash function, which has been corrected. Hopefully this will smoke out codepaths that rely on such an unwarranted assumptions.
