4.4.1

• Dropped Python 3.8 support
• Changed the signature of typeguard_ignore() to be compatible with typing.no_type_check() (PR by @jolaf)
• Avoid creating reference cycles when type checking uniontypes and classes
• Fixed checking of variable assignments involving tuple unpacking (#486)
• Fixed TypeError when checking a class against type[Self] (#481)
• Fixed checking of protocols on the class level (against type[SomeProtocol]) (#498)

• Fixed explicit checks of PEP 604 unions against types.UnionType (#467)

4.4.0

• Added proper checking for method signatures in protocol checks (#465)
• Fixed basic support for intersection protocols (#490; PR by @antonagestam)
• Fixed protocol checks running against the class of an instance and not the instance itself (this produced wrong results for non-method member checks)

4.3.0

• Added support for checking against static protocols
• Fixed some compatibility problems when running on Python 3.13 (#460; PR by @JelleZijlstra)
• Fixed test suite incompatibility with pytest 8.2 (#461)
• Fixed pytest plugin crashing on pytest version older than v7.0.0 (even if it's just present) (#343)

4.2.1

• Fixed missing typing_extensions dependency for Python 3.12 (#444)
• Fixed deprecation warning in the test suite on Python 3.13 (#444)

4.2.0

• Added support for specifying options for the pytest plugin via pytest config files (#440)
• Avoid creating reference cycles when type checking unions (PR by Shantanu)
• Fixed Optional[...] being removed from the AST if it was located within a subscript (#442)
• Fixed TypedDict from typing_extensions not being recognized as one (#443)
• Fixed typing types (dict[str, int], List[str], etc.) not passing checks against type or Type (#432, PR by Yongxin Wang)
• Fixed detection of optional fields (NotRequired[...]) in TypedDict when using forward references (#424)
• Fixed mapping checks against Django's MultiValueDict (#419)

4.1.5

• Fixed Callable erroneously rejecting a callable that has the requested amount of positional arguments but they have defaults (#400)
• Fixed a regression introduced in v4.1.4 where the elements of Literal got quotes removed from them by the AST transformer (#399)

4.1.4

• Fixed AttributeError where the transformer removed elements from a PEP 604 union (#384)
• Fixed AttributeError: 'Subscript' object has no attribute 'slice' when encountering an annotation with a subscript containing an ignored type (imported within an if TYPE_CHECKING: block) (#397)
• Fixed type checking not being skipped when the target is a union (PEP 604 or typing.Union) where one of the elements is an ignored type (shadowed by an argument, variable assignment or an if TYPE_CHECKING import) (#394, #395)
• Fixed type checking of class instances created in __new__() in cases such as enums where this method is already invoked before the class has finished initializing (#398)
