Bug Fixes:

  • Fixed bug that results in a crash under certain circumstances when a ParamSpec without a scope is used illegally to specialize a class.
  • Fixed a bug that results in a false positive error when assigning a TypeGuard[T] or TypeIs[T] to a supertype of bool (like int).
  • Fixed a bug that leads to a crash when --pythonversion and --threads CLI options are used together.
  • Fixed a bug that leads to incorrect type evaluation in certain specific conditions involving a function decorator with an return type inferred from an inner function parameterized by a ParamSpec.
  • Fixed bug that results in a false positive error under very specific conditions involving a recursive type alias that is defined in terms of another type alias.

Enhancements:

  • Changed type checking logic to retain a reference to default expressions in function signatures, including synthesized signatures (such as __init__ methods in dataclasses). This allows the original default value expression to be printed in error messages and language server strings.
  • Updated typeshed stubs to the latest version.
  • Added unreachable code reporting for case statements that are never matched based on type analysis.
