Agreed. > > 2) This is going to make development significantly harder--having to > think about the compatibility requirements, and having to test > everything with 2.x and 3.x. Yes. What is the status of the buildbots? (I've been really remiss at checking them for a very long time now). Having those would be a great help. > > 3) Most of the interactive backends will be unavailable, correct? The working ones are Qt4Agg (presumably also Pyside, though untested), and Tk. WxPython seems like it's still a long way from supporting Python 3 (though I'm not terribly plugged into that community). Gtk is probably ready to be used, I just haven't done the testing and twiddling for matplotlib yet. > > 4) I hope the 1.1.x branch doesn't have to be maintained too long; or if > it does, it would be good to have a single designated maintainer to take > care of it, backporting from master or applying custom fixes as needed. > I feel like merging in the Python 3 changes is only an improvement in this respect. Right now, I build/install/test three branches on a regular basis. After the merge, we go down to two.
