Release Notes

Released on 2026-10-22.

Bug fixes

• Improve generics solving when an intersection is passed into a generic call to prefer solving the call to a more precise type when it is safe to do so (#29578)
• Fix recursive type materialization (#29532)
• Infer return intersections from correlated call specializations (#28303)
• Preserve Self when checking universal protocols (#29207)
• Fix stack overflows involving recursive descriptor setter types (#29148)
• Preserve the namespace-package fallback in module discovery when the namespace-package fallback is obscured by a partial stub package (#29559)
• Report all missing @override decorators together (#29557)
• Fix false-positive invalid-argument-type diagnostics when inferring constrained type variables from callbacks that return an invariant generic with a gradual type argument (#29577)

Performance improvements

• Compare protocol receiver restrictions before binding (#29443)

LSP server

• Avoid cancelling requests for unrelated file changes (#29604)

Core type checking

• Generics solving: check for unsatisfiable bodies before existentially quantifying (#29504)
• Liskov diagnostics: Check inherited attribute conflicts (#28559)
• Return type inference: eneralize nested types in inferred return types (#29488)
