Behavior Change: This change may require changes to your configuration. Changed the default of the useLibraryCodeForTypes from false to true to bring pylance and pyright into alignment. Also deprecated the "--lib" command-line option, which was previously used to enable useLibraryCodeForTypes from the command line. If your project relies on the old default value, you will need to explicitly set useLibraryCodeForTypes to false in your project’s configuration file.
Behavior Change: Changed reportImportCycles so it is not on by default in "strict" type checking mode. It is highly opinionated and should be used only in cases where the developer opts into it.
Enhancement: Improved the synthesized __init__ method of a TypedDict class so it accepts another instance of the same TypedDict (or another TypedDict that is type compatible) as an argument. This makes pyright compatible with mypy in this regard.
Bug Fix: Added the ability for any callable to conform to a protocol that includes attributes and methods defined in the pseudo-class builtins.function.
Bug Fix: Fixed a bug that resulted in incorrect type evaluation when a partially-specialized generic method (with method-scoped type variables) is passed multiple times to a function that accepts generic callables.
Behavior Change: Reverted recent change that validated that explicitly-annotated self and cls in overloaded methods was a subtype of the class that contains them. This change made pyright consistent with mypy, but feedback from pyright users indicated that it was not desired. There are legitimate use cases for this in the overload case.
Bug Fix: Fixed bug that led to incorrect type narrowing for mapping patters in a case statement if the type included a recursive type alias.
Bug Fix: Fixed bug that potentially resulted in internally corrupted state when a class or def statement appears within a conditional block that is determined by the binder to be unreachable.
Bug Fix: Fixed a bug that resulted in a false positive error when assigning a function that has one or more tuple parameters to a generic callable that also accepts tuple parameters.
Bug Fix: Fixed a bug that led to a false positive error when combining a generic callback argument with a second argument that is an empty dict expression.
Bug Fix: Fixed bug in typePrinter that caused syntactically-incorrect output when using the "PythonSyntax" flag and passing a callable type that has a ParamSpec but no additional concatenated parameters.
Performance: Improved internal type caching mechanism used in cases where evaluation needs to be done speculatively (e.g. when evaluating argument expressions for an overloaded function). The previous code consumed significant memory and CPU cycles in certain circumstances.
Published 1.1.302
Bug Fix: Fixed bug that resulted in a false positive "partially unknown" error when using an augmented assignment targeting a subscripted expression within a loop.
Bug Fix: Fixed regression in CLI version that caused the default stubsPath value to stop working. This regression didn't affect the language server code paths.
Bug Fix: Fixed a bug that caused an overload function with a missing return type annotation (and a placeholder body) to have an inferred return type of None when it should be Unknown.
Enhancement: Added support for negative (fall-through) type narrowing for mapping patterns used in a case statement when the subject type includes a TypedDict with a discriminated field type (i.e. a field whose value is limited to a particular literal value).
Bug Fix: Fixed bug in constraint solver that results in incorrect code being emitted when overriding a method that includes multiple keyword-only parameters.
Bug Fix: Fixed bug that led to inconsistent behaviors when attempting to assign callable with a tuple parameter where the tuple was of indeterminate length. Previously, this generated an error if the source type parameter was a tuple with zero elements.
Enhancement: Added support for type guards of the form x[I] is B and x[I] is not B where x is a tuple and B is a boolean literal True or False or an enum literal.
Enhancement: Implemented PEP 698 (@override) support for methods decorated with @property decorator.
Bug Fix: Fixed a bug that resulted in a false negative when a self or cls parameter has an incorrect type annotation (not a subtype of the containing class) in an overloaded method.
Bug Fix: Fixed a bug that led to a false positive error when evaluating a call expression that accepts multiple generic callables, at least one of which is parameterized by a ParamSpec, where the generic types of the callables interact when being solved.
Performance: Fixed an issue that resulted in an unnecessary use of memory when transforming certain types that include TypeVars.
Bug Fix: Fixed a bug that led to a false positive when a generic function was passed as an argument to another generic function multiple times. In such a case, the second (and subsequent) instances of the function must be given unique type parameters so they are distinguished from other instances of the same function.
