Enhancement: Improved precision of error handling for tuple, list and set expressions.

Bug Fix: Fixed a bug that resulted in incorrect type narrowing for literal patterns in a match statement when the target expression type includes an instance of a class that derives from the literal's class (e.g. a subclass of str).

Bug Fix: Fixed a bug that led to the incorrect inferred return type for a super().__new__(cls) call.

Bug Fix: Added support for TypeVarTuple to capture an unpacked tuple with unbounded length.

Bug Fix: Fixed a bug that resulted in unpacked arguments to a class definition going unevaluated, which means that any symbols they referenced were not marked accessed.

Enhancement: Expanded reportUnusedExpression check to detect unused tuple, dictionary, list and set expressions if they don't contain comprehensions.

Bug Fix: Fixed a bug that resulted in a false positive when passing a generic function to an overloaded function that requires union expansion to resolve.

Bug Fix: Fixed type evaluation bug that led to a false positive error when assigning a type conditioned on a bound TypeVar to that same TypeVar in an invariant context.

Bug Fix (contribution by @timsu92): Fixed incorrect description of reportUndefinedVariable.

Bug Fix: Fixed bug in type evaluator that caused a false negative in some circumstances when constructing an instance of a generic class within that class implementation.

Bug Fix: Fixed a bug that resulted in a false negative when an annotated variable was assigned an expression that included the variable's name and the variable was undefined prior to the assignment.

Enhancement: Updated typeshed stubs to the latest version.

Bug Fix: Fixed a bug in the type checker that led it to conclude that two types were the same even though they were declared in separate modules. This occurred when the types had the same (local) name and both modules were located within project directories that contained characters that are invalid for module paths in an import statement (e.g. "-").

Enhancement: Updated PEP 695 functionality to reflect the latest changes in the spec.
