[dependabot]

Updates the requirements on typing-extensions to permit the latest version.

Changelog

Sourced from typing-extensions's changelog.

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.

Release 4.6.0 (May 22, 2023)

• typing_extensions is now documented at https://typing-extensions.readthedocs.io/en/latest/. Patch by Jelle Zijlstra.

• 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 typing_extensions version does not suffer from the bug that was fixed in python/cpython#29334. (The CPython bugfix was backported to CPython 3.10.1 and 3.9.8, but no earlier.)

• Backport CPython PR 26067 (originally by Yurii Karabas), ensuring that isinstance() calls on protocols raise TypeError when the protocol is not decorated with @runtime_checkable. Patch by Alex Waygood.

• Backport several significant performance improvements to runtime-checkable protocols that have been made in Python 3.12 (see python/cpython#74690 for details). Patch by Alex Waygood.

  A side effect of one of the performance improvements is that the members of a runtime-checkable protocol are now considered “frozen” at runtime as soon as the class has been created. Monkey-patching attributes onto a runtime-checkable protocol will still work, but will have no impact on
