Bug Fix: Fixed bug that resulted in a false positive error when a generic class used a specialized version of itself parameterized with one of its own type parameters.

Bug Fix: Fixed recent regression where imported symbols that were ultimately resolved with a native library (e.g. a ".pyd" or ".so" file) were incorrectly resolved as a module rather than an Unknown type.

Bug Fix: Fixed a type evaluation regression that caused type arguments to be incorrectly determined when calling a constructor and passing a callable that is generic.

Enhancement: Added broader support for context managers in with statements which swallow exceptions. Thanks to Rik de Graaff for this contribution.

Bug Fix: Added missing error condition for walrus operator used within a type annotation expression.

Bug Fix: Fixed bug in pattern matching type evaluation where bytearray was matched against a sequence pattern even though PEP 634 explicitly excludes this case.

Enhancement: Added support for sequence pattern match type narrowing when the subject type is a simple "object".

Enhancement: Added support for type narrowing of enums when using pattern matching.

Enhancement: Added error reporting for usage of type aliases within class pattern matching statements that generate runtime exceptions.

Behavior Change: Changed the printed type of a ParamSpec signature to avoid the use of synthesized parameter names "__p0", etc. Instead, the parameter names are omitted in the signature consistent with the emerging standard for the improved callable syntax.

Enhancement: Added support for explicit specialization of generic classes that include a ParamSpec. This is defined in PEP 612 but was previously missing.

Bug Fix: Fixed bug in check for generator return type. A diagnostic was meant to be generated if the declared return type was incorrect for a generator.
