Core
+- The type/class unification (PEP 252-253) was integrated into the
+ trunk and is not so tentative any more (the exact specification of
+ some features is still tentative). A lot of work has done on fixing
+ bugs and adding robustness and features (performance still has to
+ come a long way).

now use the Python warning framework (which makes it possible to
write filters for these warnings).
