Sourced from pyright's releases.

Bug Fix: Fixed bug that resulted in incorrect type evaluation when referencing a descriptor object that is stored as an instance variable.

Bug Fix: Fixed a bug that resulted in incorrect import resolution in a library that you are debugging locally if that library is also installed in the current Python environment and the library includes stub (".pyi") files.

Bug Fix: Fixed a bug that resulted in false positive errors during protocol matching when a generic protocol derives from another generic protocol.

Bug Fix: Fixed a long-standing bug in protocol matching where results were evaluation-order-dependent in cases where a generic source class included a method with an inferred return type that was dependent on one or more TypeVars. If the return type was not inferred and cached prior to protocol matching, it was improperly specialized.

Enhancement: Added check for illegal use of ClassVar within a TypeAlias declaration.

Bug Fix: Fixed a bug that resulted in a false positive error when performing protocol matching with a property whose getter included a custom type annotation for its self parameter.

Bug Fix: Fixed a recent regression that broke list and dictionary inference in cases where bidirectional type inference was used with an expected type that included a TypeVar that was bound to a literal type or a union of literals.

Bug Fix: Fixed bug that resulted in incorrect type evaluation when function return type inference resulted in various recursive cases.

Bug Fix: Fixed long-standing bug that resulted in incorrect code flow analysis and type evaluation when handling some forms of NoReturn calls. There are still some limitations though; for example, it doesn't handle overloaded functions that return NoReturn for some argument lists.

Published 1.1.242

Performance: Improved performance of import cycle check by adding caching.

Enhancement: Removed limitation that Literal must be imported directly from typing or typing_extensions. It can now be re-exported from another library, although analysis performance will suffer a bit in that case.

Enhancement: Improved error message for CLI version of pyright when it is passed a file that is not a Python source file.

Bug Fix: Fixed bug that resulted in infinite recursion and a crash in rare circumstances involving a self parameter annotation that referred to its own class.

Bug Fix: Fixed a bug that resulted in inconsistent type evaluation depending on evaluation ordering when a parameter or return type annotation involved a | (union) operator.

Bug Fix: Fixed bug that resulted in wrong ordering of type parameters in a generic protocol if Protocol[...] was meant to specify an explicit ordering, similar to the way Generic[...] specify an explicit ordering.

Bug Fix: Fixed bug that led to inconsistent type evaluation results when the code flow engine determined that an expression was unreachable. The results differed depending on whether there was a branch between the expression and point of the graph that was unreachable.

Bug Fix: Fixed bug in stub generator that resulted in code that was syntactically incorrect when an index subscript contained an extra "hanging" comma.

Bug Fix: Fixed a bug in the stub generator logic that produced syntactically incorrect code when the source file contained a function with a position-only separator in its signature.

Bug Fix: Fixed a bug that led to a false positive "reportOverlappingOverload" error when the return type of two overlapping overloads both used a generic return type.

Enhancement: Extended type guard for discriminated literal fields to support properties.

Bug Fix: Fixed bug in expression printer for lambda expressions. It was not properly printing a position-only separator.

Bug Fix: Fixed bug that resulted in incorrect type evaluation when using a generic type alias with an instantiable class (as opposed to a class instance) when the TypeVar used within that type alias was bound to a type[x].

Enhancement: Updated typeshed stubs to the latest version.
