Bug Fix: Fixed bug that caused "Type" with no type argument not to be flagged as an error.
Enhancement: Changed pythonPlatform to accept a value of "All" in which case no particular platform will be used over the others.
Bug Fix: Fixed bug that caused improper error when using "self" in a "raise ... from self" statement.
Bug Fix: Fixed bug that caused false negative when using a generic type alias with no type arguments.
Bug Fix: Added cache for logic that determines whether a context manager swallows exceptions (and hence acts like a try/except statement). This cache not only improves performance of code flow walks but also prevents infinite recursion in rare cases.
Behavior Change: Improved handling of unannotated decorator functions. If the decorator returns a function that accepts only *args and **kwargs (which is common), the type checker now assumes that the decorated function or method's signature is unmodified by the decorator. This preserves the original signature and docstring.
Bug Fix: Fixed bug that caused types within a "finally" clause to be evaluated incorrectly in situations where the "try" and all "except" and "else" clauses returned, raised, or broke.
Enhancement: Changed error messages that refer to "named" parameters and arguments to "keyword", which is more standard for Python.
Bug Fix: Fixed bug in declaration provider where the declaration of a member wasn't properly resolved when the LHS of the member access was a call to a function that returns a Type[X].
Bug Fix: Fixed bug that manifest as a problem with enums but was actually a problem in handling the circular dependency between "type" and "object" classes (since "type" is an object and "object" is a type).
Bug Fix: Fixed bug that caused incorrect type evaluation when a class was assigned to a generic protocol that was satisfied by the class's metaclass if the class also derived from a base class that also satisfied the same protocol.
Enhancement: Added code to test for missing annotation in Annotated.
Bug Fix: Fixed false negative where a union type was assigned to a constrained type variable. An error should be generated in this situation.
Enhancement: Added additional validation for TypeVar scoping. If an outer class defines the scope for a type var, functions and variables within an inner class cannot use a TypeVar of the same name.
Bug Fix: Improved handling of "py.typed" for namespace packages and packages with submodules.
Enhancement: Added support for __index__ magic method when used with __getitem__ or __setitem__ magic methods.
Enhancement: Added support for matching modules against protocols as specified by PEP 544.
Bug Fix: Fix for missing docs in completion list due to only checking the setter for docs because its definition comes after the getter.
