What's New in Python 2.2b2?
! Release date: 16-Nov-2001
===========================
Type/class unification and new-style classes
+
+ - Restrictions on multiple inheritance from classes with different
+ metatypes have been relaxed. The only builtin metatypes are one for
+ classic classes a second for new-style classes, so the primary
+ visible effect is that this works now:
+
+ class Classic: pass
+ class Mixed(Classic, object): now
+
+ The MRO (method resolution order) for each base class is respected
+ according to its kind, but the MRO for the derived class is computed
+ using new-style MRO rules if any base clase is a new-style class.
+ This needs to be documented.
