Bug Fix: Fixed a bug that resulted in a false positive error when accessing __required_keys__ and __optional_keys__ class variables from a TypedDict class.
Enhancement: Added support for type guard forms x is ..., x is not ..., x == ... and x != .... Support for these were recently added to mypy.
Enhancement: Added support for NoneType to be used in an isinstance type guard or match statement.
Bug Fix: Fixed a bug that resulted in a false positive when using heavily-nested call expressions that target overloads. The speculative type cache was not storing information about whether the type evaluation resulted in errors, so incorrect overloads were being chosen in the cached path.
Bug Fix: Fixed a recent regression that led to a false positive in certain cases when a call to a generic function was made within a loop.
Bug Fix: Fixed a bug that resulted in a false positive error in certain cases when using PEP 695 type parameter syntax.
Bug Fix: Fixed a bug that resulted in an incorrect type evaluation when calling a constructor on a class that uses new PEP 696 TypeVar defaults and provides an __init__ but no __new__.
Bug Fix: Fixed a bug that led to a false negative when comparing a function without a *args to a callable type with a *args.
Bug Fix: Fixed a bug in PEP 696 (TypeVar defaults) logic that resulted in a false positive error when a Self type was used within a generic method that also used a TypeVar with a default type.
Bug Fix: Fixed a bug that resulted in incorrect isinstance type narrowing in certain cases when found within a loop construct.
Bug Fix: Fixed a bug that resulted in a false positive error when a generic class used a contravariant type variable and defined a __new__ method that uses cls: type[Self] as a parameter.
Published 1.1.287
Bug Fix: Fixed false positive error in parser when an assignment expression (walrus operator) is used in a subscript list without parentheses. This was a syntax error in Python 3.8 and 3.9 but is allowed in 3.10 and newer.
Bug Fix: Fixed regression that caused an incorrect type evaluation in the presence of a doubly-nested loop.
Bug Fix: Fixed bug that sometimes resulted in incorrect type evaluation of tuple expressions used within a loop.
Bug Fix: Fixed a bug in the import cycle detection logic that led to some false negatives.
Enhancement: Addressed type evaluation performance issue by eliminating separate "incomplete type cache" and combining it with the primary type cache.
Enhancement: Improved error reporting for type mismatch involving a return type that is a TypedDict.
Bug Fix: Fixed a bug that resulted in a false positive error when resolving nested overloaded function calls where the correct overload match depends on bidirectional type inference.
Published 1.1.286
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.
