Perhaps (un)related, is the release schedule for
3.5.3 set yet? (I'm holding off putting a new version of
typing.py on typeshed until that's out.)
Not set in stone, but I have a rough plan. I want the dust to
settle around 3.6 first. So, have an RC1 in January, and then the
final release two weeks later. I'm traveling the second week of
January (#DSDad) so the RC would be either before or after that.
