Bug Fix: Fixed bug that resulted in a false positive error within type checker when a constrained TypeVar was used in a lambda callback.
Bug Fix: Fixed bug in type variable constraint solver that resulted in false positive error in certain cases involving bidirectional type inference with unknown (or missing) type arguments.
Enhancement: Reduced memory consumption of tokenizer for string literal tokens.
Enhancement: Improved performance of type analyzer in cases where certain type checking diagnostic rules are disabled.
Enhancement: Improved startup time of pyright by eliminating redundant calls to Python interpreter to retrieve import resolution paths.
Behavior Change: Automatically mark parameters as accessed (so they don't appear as "grayed out") in the following circumstances: 1) it is a self parameter in an instance method, 2) it is a cls parameter in a class method, 3) it is a parameter in a method marked abstract, 4) it is a parameter in a method that is part of a protocol class, 5) it is a parameter in an overload signature.
Bug Fix: Fixed incompatibility with pypy when retrieving import resolution paths from the configured Python interpreter.
Enhancement: Added diagnostic for __init__ method that does not have a return type of None.
Enhancement: Configuration settings can now be stored in a pyproject.toml file. If both pyproject.toml and pyrightconfig.json are both present, the latter takes precedent.
