What else for 1.0?

Besides stable APIs, solid docs, and more test coverage ... what else should we focus on for a 1.0 release? Also, where can the docs be improved? Where are there questionable API choices?

I'm putting a deadline of Feb 1 on the 1.0 milestone. That gives a timeline constraint. Hopefully we use it enough in that time to know what a solid 1.0 API looks like.
