Sourced from pyright's releases.

Published 1.1.355

Bug Fixes:

• Fixed a bug that results in incorrect type evaluation if a list expression includes a generator expression.
• Fixed bug that results in a false negative when a TypeAliasType object is used in a class pattern.
• Fixed bug that results in false positive when implicitly specializing a class parameterized by a TypeVarTuple when there is no default.
• Fixed bug that results in false positive when a list or set expression is evaluated using bidirectional type inference when the expected type is MutableSet or MutableSequence.
• Fixed bug that results in a false negative when overriding a method that has keyword parameters with a method that has a *args parameter.
• Fixed a bug that results in a false positive error in certain circumstances involving a TypeVarTuple used within an overload.
• Fixed bug that results in a false positive error when a base class defines a writable property and a subclass writes to the property.
• Fixed bug that results in a false positive "overload implementation does not match overloads" diagnostic when positional-only and keyword-only parameters are involved.
• Fixed a bug that results in a false positive in a complex situation that involves generic protocols, properties, and mix-in classes.
• Fixed bug that results in false positive error when a __new__ method in a metaclass uses PEP 692 (unpacked TypeDict) to annotate its **kwargs parameter.

Enhancements:

• Updated typeshed stubs to the latest. This version of typeshed replaces the older-style positional-only parameters with PEP 570 syntax.
• Improved validation for except and except* statements to catch some previously-undetected invalid cases.
• Expanded handling of python versions to handle more than just major/minor version numbers. Pyright now handles micro, releaseLevel, and serial numbers as well.

Published 1.1.354

Bug Fixes:

• Fixed a bug that resulted in an incorrect type evaluation when an augmented assignment is used within an inner-scoped function to add a constant to a variable. Literal math should not be used in this case.
• Fixed two bugs that resulted in false negatives when redefining a constant variable with a non-variable symbol and when redefining a Final variable with a non-variable symbol.
• Fixed bug that results in false positive when a generic class or type alias uses a TypeVarTuple followed by one or more ParamSpecs that have default values.
• Fixed bug that resulted in false negative when narrowing a constrained or bound TypeVar with a complex() or float() class pattern.
• Fixed bug that results in a false positive under certain circumstances when a constrained TypeVar is used as the default for another constrained TypeVar.
• Fixed a bug that results in a false positive under certain circumstances when defining a type alias using the old typing.TypeAlias annotation.
• Fixed a bug that results in a false negative when a class explicitly inherits from a protocol that defines an instance variable but the child re-declares as a ClassVar without an explicit type.
• Fixed a bug that made locale overrides through environment variables no longer work on node 21.

Enhancements:

• Enhanced handling of type function when it is passed a class. Pyright previously evaluated this as Any, but now it returns the class' metaclass.
• Added check for generic classes and type aliases that include a TypeVarTuple followed by a TypeVar that has a default value. This is illegal according to PEP 696.
• Changed the behavior when accessing a class attribute from a generic class that is not specialized. The class is now automatically specialized in the case using default type parameter values (from PEP 696) or Unknown. This change is required for conformance with PEP 696.
• (From pylance) Added some optimizations to the tokenizer to reduce memory usage.
• Added new reportUnhashable diagnostic rule.
