  Type/class unification and new-style classes
  
+ - New-style classes are now dynamic by default.  Previous, they were
+   static (meaning class attributes could not be assigned to) and
+   dynamic classes had to be requested by adding __dynamic__ = 1 to the
+   body of the class or to the module.  Static classes are faster than
+   dynamic classes, but dynamic classes are now at most 50% slower than
+   static classes; previously, they could be up to 10x slower.  (This
+   was accomplished by making dynamic classes faster, not by making
+   static classes slower. :-)  Note that according to one benchmark,
+   static classes are about the same speed as classic classes.
+ 
  - C.__doc__ now works as expected for new-style classes (in 2.2a4 it
    always returned None, even when there was a class docstring).
