Enhancement (from pylance): Added completion support for class variables inherited from a parent class.
Bug Fix: Fixed a bug that resulted in a stack overflow in rare cases where an unannotated decorator was used on hundreds of functions or methods within the same file.
Enhancement (from pylance): Improved completion suggestions for dict key names within an fstring expression. Double or single quotes are now chosen to avoid conflicting with the outer fstring quote type.
Bug Fix: Fixed bug that resulted in false positive error when using a member access expression within a list of base classes in a class declaration statement.
Behavior Change: Changed the heuristics in the TypeVar constraint solver to preserve literals when solving for a TypeVar in a Callable return type in cases where the source function has a declared return type with a literal annotation in it. It doesn't apply in cases involving an inferred return type or generic types that are specialized with literals.
Bug Fix: Fixed a bug in the reportUninitializedInstanceVariable check that results in a false positive when used with a dataclass or dataclass-like class. Seemingly-uninitialized class variables are implicitly overwritten by the synthesized __init__ method in a dataclass.
Performance: Fixed performance issue that occurred in certain situations involving deeply nested loops and many unannotated variables that are dependent on each other.
Enhancement: Added support for generic TypedDict classes.
