Release Notes
Released on 2025-12-03.
Bug fixes
- Fix exhaustiveness checking for match statements over unions of generic instance types (#21726)
- Don't introduce invalid syntax when autofixing override-of-final-method (#21699)
- Suppress false positives when dataclasses.dataclass(...)(cls) is called imperatively (#21729)
- Fix false positives for class F(Generic[*Ts]): ... (#21723)
- Don't confuse multiple occurrences of typing.Self when binding bound methods (#21754)
- Fix subtyping between type[T] and a union type, where T is a type variable in scope (#21740)
- Fix subtyping between type[T] and U, where T is a type variable in scope and U is a type variable not in scope (#21766)
- Fix false positives for type[tuple[...]] (#21652)
Memory usage improvements
- Significantly reduce memory usage (especially when ty is used as an LSP server) by enabling least-recently-used (LRU) cache eviction for module ASTs (#21749)
LSP server
- Add code action to ignore diagnostic on the current line (#21595)
- Exclude typing_extensions from autocomplete suggestions unless it's really available (#21731)
- Fix auto-import code action to handle pre-existing imports (#21733)
- Fix "find all references" for types defined in stub files (#21732)
- Fix "find all references" for symbols defined via aliased imports (#21736)
Improvements to handling of type aliases
- Default-specialize generic type aliases when they appear unspecialized in type expressions (#21765)
- Infer a type alias as being a generic type alias if it includes a type variable in its definition, even in cases where the value subscripted with the type variable is inferred as having a dynamic type such as Any or Unknown (#21730)
New NamedTuple diagnostics
- Detect NamedTuple classes that have field names starting with underscores, which is banned at runtime (#21697)
- Add a diagnostic detecting overrides of prohibited NamedTuple attributes (#21717)
- Detect illegal uses of super() in methods of NamedTuple classes (#21700)
Improvements to existing diagnostics
- Improve diagnostics for unsupported comparison operations (#21737)
- For invalid-type-arguments diagnostics, show the user where the type variable was defined (#21727)
- Extend invalid-explicit-override to also cover properties decorated with @override that do not override anything (#21756)
- Improve @override, @final and Liskov checks in cases where there are multiple reachable definitions (#21767)
