Bug Fix: Fixed a bug that resulted in incorrect type evaluation for a callable attribute within a TypedDict or dataclass. If the attribute has no type annotation, it should be treated as a class variable, not an instance variable.

Bug Fix: Fixed a bug that causes incorrect interpretation of a large integer literal value — one that doesn't fit within a 53-bit mantissa.

Bug Fix: Fixed a bug in the truthy/falsy type guard logic when using self (or another bound TypeVar) where the bound class implements a __bool__ method.

Bug Fix (from pylance): Fixed a bug in vscode-languageserver client that caused bogus cancellation assertion.

Bug Fix: Fixed bug in dataclass_transform logic for frozen_default. If the frozen_default is set to True, it wasn't possible to override it with False explicitly.

Bug Fix: Fixed bug that resulted in a false positive error when using the | operator to combine two set objects.

Bug Fix: Fixed a bug that resulted in an infinite loop when tuple addition was used within a loop construct.

Bug Fix: Fixed bug that led to a false positive when using method-scoped type variables in a type annotation for a cls parameter in a classmethod.

Enhancement: Added a new check for a TypeGuard or StrictTypeGuard function that does not have at least one input parameter.

Bug Fix: Fixed a bug that resulted in a false negative when bidirectional type inference was used for a list expression and a list entry with an incompatible type is present.

Enhancement: Updated typeshed stubs to the latest version.

Enhancement: Added support for x[K] is V and x[K] is not V type narrowing forms.

Enhancement: Added support for the tentatively-accepted PEP 649 (deferred evaluation of annotations) in Python 3.12.

Bug Fix: Fixed a bug that resulted in a crash within the document symbol provider when a "naked" decorator is present.

Enhancement: Added provisional support for draft PEP 702 (marking deprecations using the type system).
