4.14.1

Release 4.14.1 (July 4, 2025)

• 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.

4.14.0

This release adds several new features, including experimental support for inline typed dictionaries (PEP 764) and sentinels (PEP 661), and support for changes in Python 3.14. In addition, Python 3.8 is no longer supported.

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.

Changes included in 4.14.0rc1:

• Drop support for Python 3.8 (including PyPy-3.8). Patch by Victorien Plot.
• Do not attempt to re-export names that have been removed from typing, anticipating the removal of typing.no_type_check_decorator in Python 3.15. Patch by Jelle Zijlstra.
• Update typing_extensions.Format, typing_extensions.evaluate_forward_ref, and typing_extensions.TypedDict to align with changes in Python 3.14. Patches by Jelle Zijlstra.
• Fix tests for Python 3.14 and 3.15. Patches by Jelle Zijlstra.

New features:

• Add support for inline typed dictionaries (PEP 764). Patch by Victorien Plot.
• Add typing_extensions.Reader and typing_extensions.Writer. Patch by Sebastian Rittau.
• Add support for sentinels (PEP 661). Patch by Victorien Plot.
