| Pending removal in Python 3.19 |
| ------------------------------ |
| |
| * :mod:`ctypes`: |
| |
| * Implicitly switching to the MSVC-compatible struct layout by setting |
| :attr:`~ctypes.Structure._pack_` but not :attr:`~ctypes.Structure._layout_` |
| on non-Windows platforms. |
| |
| * :mod:`hashlib`: |
| |
| - In hash function constructors such as :func:`~hashlib.new` or the |
| direct hash-named constructors such as :func:`~hashlib.md5` and |
| :func:`~hashlib.sha256`, their optional initial data parameter could |
| also be passed a keyword argument named ``data=`` or ``string=`` in |
| various :mod:`!hashlib` implementations. |
| |
| Support for the ``string`` keyword argument name is now deprecated |
| and slated for removal in Python 3.19. |
| |
| Before Python 3.13, the ``string`` keyword parameter was not correctly |
| supported depending on the backend implementation of hash functions. |
| Prefer passing the initial data as a positional argument for maximum |
| backwards compatibility. |
