Release Notes

Bug fixes

• Add cycle detection to ty's implementation of disjointness between types, fixing a possible source of stack overflows when analysing recursive types (#19139)
• Don't allow first-party code to shadow the stdlib types module (#19128).
  This fixes another possible source of stack overflows.
• Fix descriptor lookups for most types that overlap with None (#19120).
  This means that e.g. object().__str__() now correctly binds the self argument of the __str__
  method, as the object type overlaps with None.

Server

• Filter a symbol from a stub file in autocomplete suggestions if it is an implementation detail of the stub (#19121)
• Add initial support for semantic tokens (#19108).
  This feature allows editors to apply more advanced syntax highlighting. Currently, the supported tokens are: Namespace, Class, Parameter, SelfParameter,ClsParameter, Variable, Property, Function, Method, Keyword, String, Number, Decorator, BuiltinConstant and TypeParameter.
• Initial support for workspace diagnostics (#18939).
  Enable this feature by setting the ty.diagnosticMode configuration setting to "workspace".
• Use Python syntax highlighting in on-hover content (#19082)

Typing semantics and features

• Understand that calls to functions returning Never / NoReturn are terminal with respect to control flow (#18333)
• Add subtyping between type[] types and Callable types (#19026)
• Support bare ClassVar annotations (#15768)
• Understand that two protocols with equivalent method members are equivalent (#18659)
• Support declared-only instance attributes such as self.x: int (#19048)
• Sync vendored typeshed stubs (#19174): typeshed diff
• Use the inferred type as the declared type for bare Final symbols (#19142)
