ctypes ------
* As a consequence of necessary internal refactoring, initialization of internal metaclasses now happens in ``__init__`` rather than in ``__new__``. This affects projects that subclass these internal metaclasses to provide custom initialization. Generally:
- Custom logic that was done in ``__new__`` after calling ``super().__new__`` should be moved to ``__init__``. - To create a class, call the metaclass, not only the metaclass's ``__new__`` method.
See :gh:`124520` for discussion and links to changes in some affected projects.
