I believe there was general consensus to do more maintenance releases, as witnessed in the other thread.
There have been discussions on what should go into 2.x.1, 2.x.2, etc., but I don't think we have a clear proposal. It would be nice to put that together, so committers know where all to commit patches to. Otherwise, release managers will have to look through branch-2 and pull in the fixes. Either approach is fine by me, but would be nice to start a [DISCUSS] thread on how to go about this. Any takers?
