v3.0.0

Breaking changes

• The plugin is now more strict about detecting special typing symbols like cast and Annotated, which means re-exports from a different module no longer work without using the new setting type-checking-typing-modules. Refer to the README for usage instructions.
• Drop Python 3.8 support. Add Python 3.13 support. #197

What's New

• Add support for singledispatch/singledispatchmethod. #196
• Add new setting to enforce future imports for all annotations. #200

Bug fixes

• typing.Annotated should be special-cased like typing.Literal. #193
• Make sure to visit returns not just the argument annotations. #198
• Avoid false negatives for TC001-003 related to typing.cast. #199
• Injector plugin requires all annotations in the injected function. #201

v2.6.0

What's Changed

#174 (by @Daverball) refactors the internals of the plugin to get better awareness of scopes.

This:

• Fixes scoping edge-case issues (#131)
• Fixes some false positive TC100/TC101 cases
• Fixes some rare cases where both a TC004/TC009 and a TC100/TC200 were emitted for the same symbol

---

Secondly, the PR adds support for PEP695 and adds a new plugin error code:

TC009 Move declaration out of type-checking block. Variable is used for more than type hinting

This error code is distinct from the existing, similarly sounding TC004 error, and is used to flag issues related to TypeVar definitions.

v2.5.1

What's Changed

• fix: Avoid potentially harmful TC201 false positives by @Daverball in #173

Full Changelog: v2.5.0...v2.5.1

v2.5.0

What's Changed

This release adds two new error codes:

• TC007: Type alias needs to be made into a string literal
• TC008: Type alias does not need to be a string literal

which will make the plugin handle TypeAliases, and corresponding imports, correctly.

The same PR also fixed false positive TC201 errors. Kudos to @Daverball for making it happen 👏
