Bug Fix: Fixed bug in declaration provider that caused declaration not to be found when it referred to a metadata method.
Bug Fix: Fixed bug that resulted in a false when evaluating nested lambdas (i.e. a lambda that returns a lambda).
Enhancement: Added support for bidirectional type inference for assignment expressions where the LHS is an index expression that indexes into a TypedDict instance.
Enhancement: Added support for new type narrowing pattern for discriminating among tuples. The pattern is V[I] == L or V[I] != L where I is an integer literal, L is another literal value, V is a tuple with a known length and a type at index I that is declared as a literal type.
Enhancement: Improved logging for import failures. The previous code was printing the same log message for both stub and non-stub package resolution attempts which resulted in seemingly redundant messages.
Enhancement: Added heuristic to allow proper inference of list expressions when used as the RHS operand in an expression of the form my_list + [x].
Bug Fix: Fixed a bug that was masking some error messages when multiple errors were reported for the same range and their message started with the same 25 characters.
Enhancement: Changed method and attribute override compatibility checks to check for inappropriate overrides of all base classes in the multi-inheritance case. Previously, this check used MRO, so some override mismatches were left unreported if they were obscured by another base class. The change also affects @final checks.
Enhancement: Added support for descriptor protocols defined on metaclasses.
Bug Fix: Fixed a bug that caused methods in generic classes to be specialized twice when accessed through a member access expression.
Bug Fix: Fixed false positive error when accessing __name__ instance variable in a class that derives from type.
Enhancement: Updated typeshed stubs to the latest version.
