Resurrecting an old thread: this just came up on python-dev in the context of ABI changes between alpha 3 and beta 3, and I've proposed declaring the public ABI locked as part of the upcoming beta 4 release (which is 3 weeks before the planned final release, while there's only a single week planned between the first RC and the final release) to give folks that want to pre-publish Python 3.6 wheel files more of an opportunity to do so.
