| 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. | |
| * :mod:`http.cookies`: | |
| * :meth:`http.cookies.Morsel.js_output` is deprecated and will be | |
| removed in Python 3.19. | |
| * :meth:`http.cookies.BaseCookie.js_output` is deprecated and will be | |
| removed in Python 3.19. | |
| * :mod:`imaplib`: | |
| * Altering :attr:`IMAP4.file <imaplib.IMAP4.file>` is now deprecated | |
| and slated for removal in Python 3.19. This property is now unused | |
| and changing its value does not automatically close the current file. | |
| Before Python 3.14, this property was used to implement the corresponding | |
| ``read()`` and ``readline()`` methods for :class:`~imaplib.IMAP4` but this | |
| is no longer the case since then. |
