+1 (wish * could say +sys.maxint).
- We want people to update to bug fix releases quickly. For people
to do that, they need to know the risk of breakage is low. Reducing the
scope of the release is important for that.
- Python has gotten much better at this than it used to be. I remember the
days when major features in 3rd-dot releases caused major headaches for us.
I think that made Python look bad.
