* Remove ``_use_broken_old_ctypes_structure_semantics_`` flag
from :mod:`ctypes` module.
(Contributed by Nikita Sobolev in :gh:`99285`.)

* Remove the old private, undocumented and untested ``_PyGC_FINALIZED()`` macro
which was kept for backward compatibility with Python 3.8 and older: use
:c:func:`PyObject_GC_IsFinalized()` instead. The `pythoncapi-compat project
<https://github.com/python/pythoncapi-compat/>`_ can be used to get this
function on Python 3.8 and older.
