-ctypes
-------
-
-* The layout of :ref:`bit fields <ctypes-bit-fields-in-structures-unions>`
- in :class:`~ctypes.Structure` and :class:`~ctypes.Union`
- now matches platform defaults (GCC/Clang or MVSC) more closely.
- In particular, fields no longer overlap.
- (Contributed by Matthias Görgens in :gh:`97702`.)
-
-* The :attr:`.Structure._layout_` class attribute can now be set
- to help match a non-default ABI.
