Release notes

Sourced from typing-extensions's releases.

4.16.0

No changes since 4.16.0rc2.

Changes since 4.15.0:

• Make typing_extensions.TypeAliasType's __module__ attribute writable. Backport of CPython PR #149172.
• Fix setting of __required_keys__ and __optional_keys__ when inheriting keys with the same name.
• Add support for AsyncIterator, io.Reader, io.Writer and os.PathLike protocols as bases for other protocols.
• Fix incorrect behaviour on Python 3.9 and Python 3.10 that meant that calling isinstance with typing_extensions.Concatenate[...] or typing_extensions.Unpack[...] as the first argument could have a different result in some situations depending on whether or not a profiling function had been set using sys.setprofile. This affected both CPython and PyPy implementations. Patch by Brian Schubert.
• Fix __init_subclass__() behavior in the presence of multiple inheritance involving an @deprecated-decorated base class. Backport of CPython PR #138210 by Brian Schubert.
• Raise TypeError when attempting to subclass typing_extensions.ParamSpec on Python 3.9. The typing implementation has always raised an error, and the typing_extensions implementation has raised an error on Python 3.10+ since typing_extensions v4.6.0. Patch by Brian Schubert.
• Add the bound, covariant, contravariant, and infer_variance parameters to TypeVarTuple.
• Officially support the bound, covariant, contravariant and infer_variance parameters to ParamSpec. Improve the validation of these parameters at runtime.
• Rename typing_extensions.Sentinel to typing_extensions.sentinel, following the name that has been adopted for builtins.sentinel on Python 3.15. typing_extensions.Sentinel is retained as a soft-deprecated alias for backwards compatibility.
• Add support for pickling sentinels.
• Sentinels now preserve their identity when copied or deep-copied.
• Deprecate passing name as a keyword argument or repr as a positional argument to the sentinel constructor.
• The default repr of a sentinel X = sentinel("X") is now X rather than <X>.
• Deprecate arbitrary attribute assignments to sentinels.
• Deprecate subclassing sentinels.
• Add support for Python 3.15.
• Avoid a DeprecationWarning when deprecated is applied to a coroutine function on Python 3.14.0.

4.16.0rc2

• Avoid a DeprecationWarning when deprecated is applied to a coroutine function on Python 3.14.0.

Footnotes

1. 86 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on 3.15 (091ce7b) during the generation of this report, so 2f885c8 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
