Bug Fixes:

  • Fixed bug that results in a false positive error under certain circumstances involving a call to a higher-order generic function with another function that involves a class with a contravariant type variable.
  • Fixed bug that results in a confusing error message when stub generation fails.
  • Fixed bug that results in false positive when evaluating the call to a generic function that involves a type variable used in both a covariant and contravariant (or invariant) position and both literal and non-literal types are involved.
  • Fixed bug that results in a false negative when solving a type variable that involves an invariant context.
  • Fixed a bug that can result in incorrect type inference for a subexpression that is part of an assignment expression if executed with an inference context (bidirectional type inference).
  • Fixed bug in x is E type narrowing pattern where E is an enum literal and x is a supertype of E like object.

Behavior Changes:

  • Changed behavior of constructor call evaluation when __new__ evaluation results in type evaluation errors. Previously, pyright skipped the __init__ evaluation in this case. It now proceeds to evaluate __init__, potentially generating redundant errors.
  • Removed support for inlined TypedDict annotations. This was an experimental feature that never gained enough support to make it into a PEP.
  • Changed behavior of pyright to match the latest typing spec when it encounters an attribute with a type annotation within an Enum class body in a stub. These are now treated as non-member attributes rather than members. Typeshed stubs have been updated to conform to the new standard.
  • Added diagnostic check for an enum member with a type annotation. The typing spec says that this should be considered a typing error.

Enhancements:

  • Updated typeshed stubs to the latest version.
