Bug Fix: Fixed recent regression that resulted in a crash (stack overflow) in the code flow engine.
Bug Fix: Fixed a bug that resulted in unknown types in member access expressions to go unreported with reportUnknownMemberType was enabled. This occurred when the member access expression was located within a subscript of an index expression.
Performance: Changed the logic that infers a NoReturn type to avoid inferring symbol types. This was causing a bunch of extra work to be performed in complex unannotated code bases like sklearn.
Performance: Fixed performance issue in parser for deeply-nested parenthesized expressions.
Bug Fix: Fixed bug in callable type compatibility logic. It was not properly handling some edge cases where a keyword parameter in the source and destination had an incompatible type if one or both of the types were specialized.
Bug Fix: Fixed a bug that resulted in false positives when specializing a callback protocol with a TypeVarTuple when the callback protocol also contained one or more keyword parameters that were generic.
Bug Fix: Fixed a bug in the protocol invariance checking logic. It wasn't properly handling protocols that used a TypeVarTuple as a type parameter that wasn't last (right-most) in the type parameter list.
Behavior Change: Changed import resolution order to more closely match PEP 561. Typeshed stdlib type stubs are now resolved later in the import resolution process, after all local modules and modules within the python environment.
