Bug Fix: Fixed bug in parser that resulted in the opening parenthesis ("(") in a parenthesized expression or tuple not being included in the parse node range.

Bug Fix: Fixed bug that could result in "unaccessed variable" error for variables that were referenced in argument expressions if there were other errors related to the call expression.

Bug Fix: Fixed bug in logic dealing with comment-style function annotations that resulted in spurious errors if "self" was used within an instance method that was so annotated.

Bug Fix: Fixed bug that caused errors when a hierarchy of dataclass classes used generic types for one or more dataclass members.

Bug Fix: Fixed bug in type checker where it allowed invariant type parameters to violate invariance if the destination was an "object" instance.

Bug Fix: Fixed off-by-one error in fstring parsing with debug variables that resulted in errors if the "=" was not preceded by a space.

Bug Fix: Fixed bug in logic that validates the assignment of a callable type to a generic callable when one of the parameters is another callable.

Bug Fix: Fixed bug that affected generic type aliases that included callable types.

Bug Fix: Fixed bug in bidirectional type inference logic when RHS includes call that returns a generic type. The old logic was prepopulating the type associated with that TypeVar but prevented the type from being further narrowed. This resulted in incorrect errors with argument expressions in some cases.

Enhancement: Added PEP 604 support for unions passed as the second argument to isinstance and issubclass.

Enhancement: Improved error messages for binary operations that involve a TypeVar for one of the operands.

Enhancement: Updated the reportMissingTypeArgument diagnostic check to apply to bound types in TypeVar declarations.
