FYI: we're making a new release (right now!) with the patch applied, that should go out tomorrow.

If anyone spots anything important in the patch, I still really want to hear about it, but hopefully having something installable means we'll get at least a few days of testing before locking it in.

All my apologies for waiting until the last minute before giving up on the crusade to avoid including the versioned files in Python. The timing is unfortunate, but I'm sure we're going to have the best compatibility story possible right now. So thanks for indulging me, and I hope I haven't put too many people through too much anguish.
