Replace the builtin :mod:`hashlib` implementations of SHA2-224 and SHA2-256
|
|
originally from LibTomCrypt with formally verified, side-channel resistant
|
|
code from the `HACL* <https://github.com/hacl-star/hacl-star/>`_ project.
|

The builtins remain a fallback only used when OpenSSL does not provide them.

In accordance with :PEP:`699`, the ``ma_version_tag`` field in
|
|
:c:type:`PyDictObject` is deprecated for extension modules. Accessing this
|
|
field will generate a compiler warning at compile time. This field will be
|
|
removed in Python 3.14.

a GCC-only flag.

The ``py.exe`` launcher now correctly filters when only a single runtime is
|
|
installed. It also correctly handles prefix matches on tags so that ``-3.1``
|
|
does not match ``3.11``, but would still match ``3.1-32``.
