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. They 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, it can be resubmitted when new interest arises). The seventh batch of topics have now graduated to the 'master' branch. 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/ Release tarballs are available at: https://www.kernel.org/pub/software/scm/git/ -------------------------------------------------- [New Topics] * jc/remote-insteadof-leakfix (2026年07月25日) 1 commit - remote: plug memory leaks rewrites_release() in 'remote.c' has been updated to free 'struct rewrite' instances and their '.instead_of' arrays, and their contents.
