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). There are too many topics marked with "Needs review" label. I can help reviewing some of them myself, but obviously it will not scale. For now, I'll let unreviewed new topics accumulating in the mailing list archive without picking them up in 'seen' to encourage folks help reduce the review backlog. 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.
