v4.15.0

Compare Source

No user-facing changes since 4.15.0rc1.

v4.14.1

Compare Source

• Fix usage of typing_extensions.TypedDict nested inside other types
  (e.g., typing.Type[typing_extensions.TypedDict]). This is not allowed by the
  type system but worked on older versions, so we maintain support.

v4.14.0

Compare Source

Changes since 4.14.0rc1:

• Remove __or__ and __ror__ methods from typing_extensions.Sentinel
  on Python versions <3.10. PEP 604 was introduced in Python 3.10, and
  typing_extensions does not generally attempt to backport PEP-604 methods
  to prior versions.
• Further update typing_extensions.evaluate_forward_ref with changes in Python 3.14.

v4.13.2

Compare Source

• Fix TypeError when taking the union of typing_extensions.TypeAliasType and a
  typing.TypeAliasType on Python 3.12 and 3.13.
  Patch by Joren Hammudoglu.
• Backport from CPython PR #​132160
  to avoid having user arguments shadowed in generated __new__ by
  @typing_extensions.deprecated.
  Patch by Victorien Plot.

v4.13.1

Compare Source

Bugfixes:

• Fix regression in 4.13.0 on Python 3.10.2 causing a TypeError when using Concatenate.
  Patch by Daraan.
• Fix TypeError when using evaluate_forward_ref on Python 3.10.1-2 and 3.9.8-10.
  Patch by Daraan.

v4.13.0

No user-facing changes since 4.13.0rc1.

v4.12.2

Compare Source

• Fix regression in v4.12.0 where specialization of certain
  generics with an overridden __eq__ method would raise errors.
  Patch by Jelle Zijlstra.
• Fix tests so they pass on 3.13.0b2

v4.12.1

Compare Source

• Preliminary changes for compatibility with the draft implementation
  of PEP 649 in Python 3.14. Patch by Jelle Zijlstra.
• Fix regression in v4.12.0 where nested Annotated types would cause
  TypeError to be raised if the nested Annotated type had unhashable
  metadata. Patch by Alex Waygood.

v4.12.0

Compare Source

This release is mostly the same as 4.12.0rc1 but fixes one more
longstanding bug.

• Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and
  3.9 that meant that
  isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a
  different result in some situations depending on whether or not a profiling
  function had been set using sys.setprofile. Patch by Alex Waygood.
