| The hash of :class:`BuiltinMethodType` instances (methods of built-in classes) | |
| now depends on the hash of the identity of *__self__* instead of its value. | |
| The hash and equality of :class:`ModuleType` and :class:`MethodWrapperType` | |
| instances (methods of user-defined classes and some methods of built-in classes | |
| like ``str.__add__``) now depend on the hash and equality of the identity | |
| of *__self__* instead of its value. :class:`MethodWrapperType` instances no | |
| longer support ordering. |
