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.
Bug Fix: Changed the evaluated type of an exception group from ExceptionGroup
to BaseExceptionGroup
.
Bug Fix: Improved type inference for unpacking of tuples that include unpacked tuples whose lengths are unknown.
Bug Fix: Fixed a bug that led to a false positive error when calling a constructor using bidirectional type inference on a generic class that defines a __new__
method but no __init__
method.
Bug Fix: Fixed bug that resulted in a false negative when Never
is used as a type argument for an invariant type parameter.
Bug Fix: Fixed a bug that led to a false positive error when applying bidirectional type inference to a call expression that invokes a generic function where the return type includes a generic class with multiple type arguments, some of which are supplied by the expected type and some of which are not.
Bug Fix: Fixed bug that resulted in incorrect type narrowing in the negative (fall-through) case for certain value patterns in a match
statement.
Enhancement: Updated typeshed stubs to the latest version.
