Nominating for 1.0-beta milestone.

Stability requests from users are on a discuss thread.

[alexcrichton]

I'm going to try to keep track of all requests from the discuss thread in a gist

This is subsumed by the new beta stabilization tracker, which includes the last changes prior to alpha2: #22500

Closing!
