[dependabot]

Bumps typing-extensions from 4.12.2 to 4.15.0.

Release notes

Sourced from typing-extensions's releases.

4.15.0

No user-facing changes since 4.15.0rc1.

New features since 4.14.1:

• Add the @typing_extensions.disjoint_base decorator, as specified in PEP 800. Patch by Jelle Zijlstra.
• Add typing_extensions.type_repr, a backport of annotationlib.type_repr, introduced in Python 3.14 (CPython PR #124551, originally by Jelle Zijlstra). Patch by Semyon Moroz.
• Fix behavior of type params in typing_extensions.evaluate_forward_ref. Backport of CPython PR #137227 by Jelle Zijlstra.

4.15.0rc1

• Add the @typing_extensions.disjoint_base decorator, as specified in PEP 800. Patch by Jelle Zijlstra.
• Add typing_extensions.type_repr, a backport of annotationlib.type_repr, introduced in Python 3.14 (CPython PR #124551, originally by Jelle Zijlstra). Patch by Semyon Moroz.
• Fix behavior of type params in typing_extensions.evaluate_forward_ref. Backport of CPython PR #137227 by Jelle Zijlstra.

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

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
