Sourced from pyright's releases.

Published 1.1.391

Bug Fixes:

• Fixed a bug that results in a crash under certain circumstances when Self is errantly specialized.
• Fixed bug that leads to incorrect evaluations when a ClassVar and Final qualifier are both used on the same dataclass attribute.
• Fixed bug that leads to a hang when returning a tuple from a lambda argument expression in certain circumstances.
• Fixed bug that results in incorrect evaluation of a generic dataclass entry when the entry is defined by a generic subclass.
• Fixed bug that leads to a false positive error when --verifytypes is used and a subclass overrides an attribute that is generic in the base class.
• Fixed bug that results in the command-line version of pyright not handling long file lists provided via stdin.
• Fixed bug that results in spurious type evaluation error when an operator overload method like __add__ is implemented with a descriptor object.
• Fixed bug that results in confusing error messages when using --verifytypes while targeting a submodule within a package and that submodule is a single-file module.
• Fixed recent regression in isinstance type narrowing logic that affects the case where the filter type is a metaclass.
• Fixed bug that results in order-dependent type errors under certain circumstances involving converter functions in a dataclass.

Enhancements:

• Improved error message for incorrect exception type in an except clause.
• Added exemption to the reportUnnecessaryComparison rule for simple wildcard patterns in a case clause.

Published 1.1.390

Bug Fixes:

• Fixed recent regression that results in incorrect narrowed type when using the x in y pattern where y is a container type whose element type is Unknown or Any.
• Fixed bug that causes a false positive overlapping overload error when the overload accepts a Callable[..., T] form.
• Fixed a bug that results in a hang under certain circumstances when using a recursive type alias.
• Fixed a bug that leads to a false positive when a function is decorated and has no explicit return type annotation and the body references the decorated function in a loop.
• Fixed a bug that leads to incorrect type evaluation when __getitem__ is set to a callable object.
• Fixed bug that results in confusing error message when there is a partially-unknown metaclass type detected by the --verifytypes command.

Enhancements:

• Updated typeshed stubs to the latest version.
• Added check for \u and \N escapes within bytes literals, which are illegal.
• Added support for a "bare" Final annotation in a dataclass entry that has a default value assigned to it.
• Improved dataclass converters to support generic types.
• Added check for importing a Final variable from another module and then attempting to overwrite it.
• Added check for an attempt to assign to a module-local variable if it is shadowing a Final variable declared by the builtins module or some other chained file.
• Added support for evaluating the slice class type arguments for slice expressions.
• Added check for invalid use of ClassVar qualifier within a NamedTuple or TypedDict attribute annotation.

Behavior Changes:

• Changed inference logic for exception groups to more closely match the runtime. If a non-base exception is targeted, the inferred type is now ExceptionGroup rather than BaseExceptionGroup.

Published 1.1.389

Bug Fixes:

• Fixed bug that results in a false negative if a | union operator creates a union of generic types. These types should be specialized with default type arguments.
• Fixed bug that results in false negative when raising a value of type None.
• Fixed bug that results in an incorrect type evaluation when a match statement uses a pattern with a target expression that overwrites the subject expression.
• Fixed bug that results in a missing reportUnknownArgumentType error if the argument is an expression involving an __init__ parameter in an unannotated (pseudo-generic) class.
• Fixed bugs that resulted in false positive errors when using an expression of the form type(A) as a base class or a metaclass in a class definition.
• Fixed bug that leads to false positive when a method is overridden by a polymorphic method.
• Fixed bug that affects pyproject.toml files with an emoji character by switching to a different toml parser.
• Fixed a bug that results in a false negative when a class is used in a type annotation for a method parameter and both the class and the method are generic and use PEP 695 syntax.
• Fixed a bug that results in a false positive "--verifytypes" error when using an explicit TypeAliasType call to create a public symbol in a "py.typed" library.
