@@ -4,6 +4,16 @@ Release date: 28-Sep-2100 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). |
