Release 4.7.1 (July 2, 2023) - Fix support for `TypedDict`, `NamedTuple` and `is_protocol` on PyPy-3.7 and PyPy-3.8. Patch by Alex Waygood. Note that PyPy-3.7 and PyPy-3.8 are unsupported by the PyPy project. The next feature release of typing-extensions will drop support for PyPy-3.7 and may also drop support for PyPy-3.8. Release 4.7.0 (June 28, 2023) - This is expected to be the last feature release supporting Python 3.7, which reaches its end of life on June 27, 2023. Version 4.8.0 will support only Python 3.8.0 and up. - Fix bug where a `typing_extensions.Protocol` class that had one or more non-callable members would raise `TypeError` when `issubclass()` was called against it, even if it defined a custom `__subclasshook__` method. The correct behaviour -- which has now been restored -- is not to raise `TypeError` in these situations if a custom `__subclasshook__` method is defined. Patch by Alex Waygood (backporting python/cpython#105976).
