Bug Fixes:

• Fixed a bug that results in a false positive error in the reportUnknownMemberType check when abc.Callable (without any type arguments) is used in the second argument to an isinstance call.
• Fixed bug in literal pattern matching that resulted in incorrect narrowing when the subject was typed with a constrained TypeVar.
• Fixed bug that led to incorrect conversion from a class constructor to a function when it involves a __new__ method that returns Self.
• Fixed bug that resulted in crash under certain obscure circumstances where a class with multiple type parameters is explicitly specialized with only a subset of required type arguments.
• Eliminated some differences between the treatment of type and Type. These should be treated the same under all circumstances.
• Fixed recent regression that resulted in a false positive when accessing a class property from a class instance.
• Fixed a bug that can result in spurious false positive errors when using deeply-nested or recursive type definitions such as _NestedSequence in numpy.
• Fixed bug that led to a false negative when Never is used as an explicit type argument for a generic class or type alias if the corresponding type parameter is a constrained TypeVar.
• Fixed bug that produces a false negative when attempting to assign a method to a Callable type where the first parameter of the method is typed as Self, but the callback requires the class itself.
• (from Pylance) Fixed bug that led to false positive errors related to import resolution when a partial stub is used and its directory structure doesn't match that of the library.

Enhancements:

• Improved error handling for failures when explicitly specializing a generic type alias. Improved diagnostic message for assert_type failures when printed types look the same when not using the full name of the type.
• Added support for bidirectional type inference for chained assignment expressions.
• Updated typeshed stubs to the latest version.
• Added deprecation message for class properties, which were deprecated in Python 3.11 and are going away in Python 3.13.
• Added support for parameter type inference for lambdas whose parameters include default arguments. This is analogous to the logic used for unannotated function parameters with default arguments.

Behavior Changes:

• Changed the behavior for empty dict or list expressions. Previously, a variable initialized with {} or [] was not flagged as "partially unknown" by the reportUnknownArgument check when used as an argument to a call. This resulted in a small type hole.
• Changed type evaluation logic for member access expressions for type[Any] where the target attribute is not explicitly declared in the type or object class. Previously, pyright emitted an error in this case.
