The :mod:`ssl` module sets more secure cipher suites defaults. Ciphers
|
|
without forward secrecy and with SHA-1 MAC are disabled by default. Security

level 2 prohibits weak RSA, DH, and ECC keys with less than 112 bits of
|
|
security. :class:`~ssl.SSLContext` defaults to minimum protocol version TLS
|
|
1.2. Settings are based on Hynek Schlawack's research.

:mod:`ipaddress` module no longer accepts any leading zeros in IPv4 address
|
|
strings. Leading zeros are ambiguous and interpreted as octal notation by
|
|
some libraries. For example the legacy function :func:`socket.inet_aton`
|

treats leading zeros as octal notation. glibc implementation of modern
|
|
:func:`~socket.inet_pton` does not accept any leading zeros. For a while the

[Enum] Deprecate ``TypeError`` when non-member is used in a containment
|
|
check; In 3.12 ``True`` or ``False`` will be returned instead, and
|

containment will return ``True`` if the value is either a member of that
|
|
enum or one of its members' value.

:func:`typing.get_type_hints` will search through the global then local

defined on an object. It works around the quirks of accessing the

annotations from various types of objects, and makes very few assumptions

Fix check for macOS SDK paths when building Python. Narrow search to match
|
|
contents of SDKs, namely only files in ``/System/Library``,
|
|
``/System/IOSSupport``, and ``/usr`` other than ``/usr/local``. Previously,
|
|
anything under ``/System`` was assumed to be in an SDK which causes problems
|
|
with the new file system layout in 10.15+ where user file systems may appear
|
|
to be mounted under ``/System``. Paths in ``/Library`` were also
|
|
incorrectly treated as SDK locations.

allocators are now installed by default if Python is built in debug mode (if

test if an object is, respectively, the ``None`` singleton, the ``True``
