Bug Fixes:
- Fixed a bug that causes
warnings.deprecatednot to work if the python version is 3.13. This was caused by recent changes to typeshed stubs. - Fixed bug that results in inconsistent diagnostics when surrounding an argument expression with parentheses.
- Fixed bug that causes a "bare"
type(with no type argument) ortype[Any]to be treated as a possible descriptor object. - Fixed regression that results in an internal assertion (and crash) related to TypeVar variance inference.
- Fixed a bug in the "type printer" (the component responsible for translating a type into its textual form) for type aliases defined using PEP 695 syntax.
- Fixed bug that resulted in the incorrect synthesis of
__dataclass_fields__for named tuples. - (Contributed by @insync) Fixed
stubPath's default value in configuration schema. - Fixed bug in pattern matching for
Callable()in the negative (fall-through) case. - Fixed bug that results in unions consisting of different specialized forms of a generic TypedDict to "lose" all but one of these subtypes.
Behavior Changes:
- Changed inference behavior for generator functions with no reachable
yieldoryield fromstatements. The "yield type" (the first type argument toGenerator) is now inferred asNeverin this case rather thanNone. - Changed the behavior of double underscored symbols that are part of a module's namespace when that module is not a stub or in a "py.typed" package. Such symbols are no longer ignored, although they are considered private.
- Changed the way that PEP 695 type aliases are displayed when hovering over a reference to the type alias. Previously, the symbol was displayed as
TypeAliasTyperather than the expanded type alias type.
Enhancements:
- Added support for
deprecatedobjects that are instantiated prior to being used as a decorator. This allows for a factory usage pattern. - Added check for illegal use of
Protocoltype argument that is not a type parameter. The runtime generates an exception for this condition.
