Bug fixes

• Emit a diagnostic if a class decorator is not a callable accepting a type (#​22375)
• Fix exhaustiveness inference for unions that include enums (#​22290)

Core type checking

• Support typing.TypeGuard (#​20974)
• Treat __setattr__ as fallback-only (#​22014)
• Don't expand type aliases via type mappings unless necessary. This means that the displayed signature of a bound methods will no longer eagerly expand type aliases into their aliased types (#​22241)
• Narrow TypedDict unions with not in (#​22349)
• Don't including property in subclasses properties (#​22088)
• Narrow tagged unions of TypedDicts in match statements (#​22299)
• Teach bidirectional inference about subtyping. This allows x to be inferred as list[int] for x: Iterable[int] = [42] (#​21930)
• Support narrowing for tagged unions of tuples where one element of the tuple is a Literal type (#​22303)

LSP server

• Add autocomplete suggestions for keyword arguments in class statements (#​22110)
• Avoid showing misleading inlay hint for unpacked tuple arguments (#​22286)

Other changes

• Sync vendored typeshed stubs (#​22302, #​22321, #​22324). Typeshed diff
