+# Unreleased
+
+- Speedup `issubclass()` checks against simple runtime-checkable protocols by
+ around 6% (backporting https://github.com/python/cpython/pull/112717, by Alex
+ Waygood).
+- Fix a regression in the implementation of protocols where `typing.Protocol`
+ classes that were not marked as `@runtime-checkable` would be unnecessarily
+ introspected, potentially causing exceptions to be raised if the protocol had
+ problematic members. Patch by Alex Waygood, backporting
+ https://github.com/python/cpython/pull/113401.

# Release 4.9.0 (December 9, 2023)
This feature release adds `typing_extensions.ReadOnly`, as specified

# fix test_generic_protocols_special_from_protocol with latest Python

BuildArch: noarch
BuildRequires: python3-devel

%global _description %{expand:
The typing_extensions module serves two related purposes:
Enable use of new type system features on older Python versions.
For example, typing.TypeGuard is new in Python 3.10, but typing_extensions
allows users on previous Python versions to use it too.
Enable experimentation with new type system PEPs before they are accepted and
added to the typing module.
typing_extensions is treated specially by static type checkers such as mypy and
pyright. Objects defined in typing_extensions are treated the same way as
equivalent forms in typing.
typing_extensions uses Semantic Versioning. The major version will be
incremented only for backwards-incompatible changes. Therefore, it's safe to
depend on typing_extensions like this: typing_extensions >=x.y, <(x+1),
where x.y is the first version that includes all features you need.}
