Bug Fix: Fixed a bug that resulted in a false positive "reportMissingParameterType" error when using an old-style double underscore parameter name to indicate position-only parameter.

Bug Fix: Handled the special case where an Any expression is bound to a ParamSpec giving it default parameters.

Bug Fix: Fixed bug that resulted in a false positive error when using a dictionary unpack operator ** with an instance of a class that satisfied the SupportsKeysAndGetItem protocol but did not directly derive from Mapping.

Enhancement: Added new diagnostic check reportUnusedExpression to catch bugs like a == 4 when a = 4 was intended.

Enhancement: Added special-case logic for a Type[T] (where T is an unbound TypeVar) that is instantiated through a call to its constructor. It should evaluate to T rather than Any.

Bug Fix: Fixed bug in pattern exhaustive match logic that failed to detect exhaustive match when the subject expression was a unnarrowable expression form.

Bug Fix: Improved the heuristics in the alias resolution logic to prefer declarations that are in non-exception paths even if the exception path has a typed decl and the non-exception decl must be inferred.

Bug Fix: Fixed two bugs that generated false positive errors when using PEP 604 union syntax in an implicit type alias. The first bug affected the case where the union started with None. The second affected the case where a TypeVar was included in the union.

Enhancement: Updated typeshed stubs to the latest.

Bug Fix: Fixed bug that resulted in false positive reportIncompatibleVariableOverride error when one base class defined a symbol as a property and another base class defined a symbol as Any.

Enhancement: Added support for the use of Concatenate as a type argument for a generic type alias that accepts a ParamSpec.
