Bug Fix: Fixed a bug in assertNever internal function that resulted in a crash when attempting to stringify a recursive data structure. This shows up occasionally in the crash telemetry.

Bug Fix: Fixed an infinite recursion bug in the type printer that shows up occasionally in the crash telemetry.

Bug Fix: Fixed a bug that resulted in infinite recursion when a global statement is used within the global scope of a module.

Enhancement: Added new check for an attempt to instantiate Dict, Set, List, or Tuple from typing module. This generates a runtime exception.

Bug Fix: Fixed recent regression that resulted in a false positive error when defining a variable in a class body and using its own field name as a type annotation.

Bug Fix: Fixed bug that results in incorrect narrowing for sequence patterns in a match statement in the negative (fall-through) case when the subject type is a tuple of known length but with elements of type Any.

Enhancement: Added support for quoted TypeAlias type annotation.

Bug Fix: Fixed a bug that resulted in incorrect type evaluation when narrowing types for class patterns in a match statement when the matched class is a generic subclass of the subject type.

Bug Fix: Fixed bug that resulted in incorrect type evaluation when an isinstance type guard results in an intersection type and one of the sources of the intersection is a conditional type.

Bug Fix: Fixed a bug that resulted in a transient false positive error in certain cases where a member access expression was used within a quoted type annotation.
