Fix a regression introduced in v4.6.0 in the implementation of
runtime-checkable protocols. The regression meant
that doing class Foo(X, typing_extensions.Protocol), where X was a class that
had abc.ABCMeta as its metaclass, would then cause subsequent
isinstance(1, X) calls to erroneously raise TypeError. Patch by
Alex Waygood (backporting the CPython PR
python/cpython#105152).
Sync the repository's LICENSE file with that of CPython.

Skip a problematic test on Python 3.12.0b1. The test fails on 3.12.0b1 due to
a bug in CPython, which will be fixed in 3.12.0b2. The
typing_extensions test suite now passes on 3.12.0b1.
Release 4.6.2 (May 25, 2023)
Fix use of @deprecated on classes with __new__ but no __init__.
Patch by Jelle Zijlstra.
Fix regression in version 4.6.1 where comparing a generic class against a
runtime-checkable protocol using isinstance() would cause AttributeError
to be raised if using Python 3.7.
Release 4.6.1 (May 23, 2023)
Change deprecated @runtime to formal API @runtime_checkable in the error
message. Patch by Xuehai Pan.
Fix regression in 4.6.0 where attempting to define a Protocol that was
generic over a ParamSpec or a TypeVarTuple would cause TypeError to be
raised. Patch by Alex Waygood.
Add typing_extensions.Buffer, a marker class for buffer types, as proposed
by PEP 688. Equivalent to collections.abc.Buffer in Python 3.12. Patch by
Jelle Zijlstra.
Backport two CPython PRs fixing various issues with typing.Literal:
python/cpython#23294 and
python/cpython#23383. Both CPython PRs were
originally by Yurii Karabas, and both were backported to Python >=3.9.1, but
no earlier. Patch by Alex Waygood.
A side effect of one of the changes is that equality comparisons of Literal
objects will now raise a TypeError if one of the Literal objects being
compared has a mutable parameter. (Using mutable parameters with Literal is
not supported by PEP 586 or by any major static type checkers.)
Literal is now reimplemented on all Python versions <= 3.10.0. The
