Bug Fix: Reverted a recent update to the TOML parser that resulted in a regression. This reversion means that some TOML 1.0 features will not be handled correctly.
Bug Fix: Fixed a bug that resulted in incorrect handling of literals in the TypeVar constraint solver. This involved a pretty significant change to the constraint solver logic — one that eliminated some heuristics and special cases.
Bug Fix: Fixed a bug that caused target expressions within a chained assignment to be evaluated in the wrong order (right to left instead of left to right). This resulted in false positives and negatives in some cases where one target referred to another target. This change also makes it illegal to use a Python 2-style type comment on a line containing a chained assignment statement, reflecting the fact that Python 3-style variable type annotations are not legal here either.
Enhancement: Improved handling of TypeVarTuple constraint solving. Previously, if a TypeVarTuple appeared more than once, the corresponding tuple types needed to be identical. The constraint solver now supports the same sort of narrowing/widening within the tuple entries to find the best solution.
Bug Fix: Fixed a bug that led to a false negative during protocol matching if the protocol class refers to itself within an invariant type argument.
Enhancement: Improved handling of generic functions passed as arguments to generic higher-order functions. Pyright is now able to solve the type variables for both the generic callback and the called function.
Enhancement: Updated typeshed stubs to the latest version.
Enhancement: Improved handling of generic functions passed as arguments to generic higher-order functions that use a ParamSpec. Pyright is now able to solve the type variables for both the generic callback and the called function.
Bug Fix: Fixed a bug in the code flow engine that resulted in incorrect type evaluation in some cases involving double nested loops.
Bug Fix: Improved the method override consistency checks to detect the case where an override uses an *args parameter that is not type compatible with the overridden method's parameter types. Thanks to @mehdigmira for this contribution.
Enhancement: Improved handling of TypeVars that appear only within a Callable within a return type annotation for a function. By a strict reading of PEP 484, these should be bound to the function's scope, but practically, they are bound to the Callable. This allows a function to return a generic callable type. When TypeVars are rescoped in this manner, the TypeVar cannot be referenced within the function body because it is no longer in scope in that context.
Enhancement: Improved error handling for NewType calls
Enhancement: Completed initial implementation of PEP 696. Added support for default TypeVar types that refer to other TypeVars.
