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.
