Release Notes

Released on 2026-01-05.

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
