Modified behavior of overload matching when unpacked argument is present and the unpacked iterator is a type that doesn't provide any length information. In this case, overload matching will prefer an overload that includes a *args parameter rather than individual positional parameters.

Modified behavior for assignment-based type narrowing when the target of the assignment references an "asymmetric" descriptor or property, one where the setter accepts a different value type than the getter returns. When this is detected, assignment-based type narrowing is no longer applied.

Improved isinstance type narrowing when the original type is a generic class with a TypeVar as a type argument and the second argument to isinstance is a generic subclass of the original type. The type argument is now properly retained.

Implemented support for type guards that are based on a local variable that is assigned an expression that narrows the type of the assigned expression. Some limitations apply. For details, refer to https://github.com/microsoft/pyright/blob/main/docs/type-concepts.md#narrowing-based-on-local-variable .

Fixed a bug whereby an explicit TypeAlias definition that includes a generic type with no explicit type arguments was not assuming Unknown for those type arguments. For example, A: TypeAlias = list should assume that A is equivalent to list[Unknown].

Added a missing diagnostic for an attempt to specialize a class that has already been specialized. This can occur in the case of a type alias, such as `A = list[int], A[int]`.
