- Installing on Mac for 3.0 is fixed.
- test_multiprocessing hangs have been fixed.
- gettext has gotten a different API.
- Tracebacks now display their causes and contexts. See exception chaining.
- Antoine Pitrou got commit access. Yeah!
Even now, the planned final release date in October looms, so we need lots of people to test their application and libraries with the beta release and file bug reports.
