Enhancements:

• Added support in dataclass_transform for custom field specifiers that have default arguments for their init or kw_only parameters.
• Implemented check for inconsistent use of @staticmethod and @classmethod in overloads.
• Added support for accessing members of a TypeAliasType object.
• Added an error check for a PEP 695 type statement within a function body. Type alias definitions are not allowed within this scope.
• Added support for *args: *Ts parameter that captures a callable with an indeterminate number of positional parameters because some of them have default arguments.
• (Contribution from @jbarrachinab) Improved a few error messages in the Spanish localization.
• Enhanced support for TypeVarTuple capture of a callable to support literal arguments.
• Added a few optimizations that help improve perf somewhat when large unions are involved.
• Added support for doc strings when using the PEP 695 type statement.

Behavior Changes:

• Added a new typeCheckingMode called "standard". It's a subset of "strict" but a superset of "basic". It is the new default mode, and it should cover all of the required checks for conformance with the Python typing standard.
• Changed behavior of check for unimplemented methods in a class that explicitly derives from a protocol. If the class also explicitly derives from abc.ABC, it is exempted from this check. This is useful for mixin classes.
• Changed behavior of reportUnknownMemberType (and other checks in the reportUnknown... family) to not report a partially-unknown type if it refers to an unspecialized class.
• Moved checks for Required/NotRequired and ReadOnly overrides from reportGeneralTypeIssue to reportIncompatibleVariableOverride for consistency. Added checks for Required/NotRequired and Readonly incompatibilities in the multiple inheritance case.
• Changed behavior of two-argument form of super when it is used outside of an attribute access expression. It now employs a heuristic whereby it evaluates to the next base class of the bound type.
• Changed the type printer logic to avoid emitting truncated Literal string and bytes values when it is asked to enforce Python syntax. This mode is used for inlay hints and the stub generator (for inferred return type comments).

Published 1.1.338

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 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.

Published 1.1.337

Bug Fixes:

• Fixed a bug that resulted in a false positive error when using a walrus operator in a call expression that targets an overloaded function.
• Fixed bug that led to a hang (infinite loop) in the language server when opening a document whose URI wasn't a "file". This occurred in some language servers that used an "untitled" (or similar) URI type for new documents.
• Modified recent bug fix in isinstance and issubclass type narrowing logic so it better handles type variables with bounds that are unions.
• Fixed a bug that resulted in a false positive error when a higher-order generic function is passed another generic function as an argument along with another argument that dictates the type of the first argument's type variable(s). This shouldn't depend on the order in which the arguments are passed.
• Fixed a bug that resulted in a false positive error when a higher-order generic function is passed another generic function as an argument along with another argument that dictates the type of the first argument's type variable(s). This shouldn't depend on the order in which the arguments are passed.
• Fixed a recent regression that resulted in a false positive error when a parent class defines a property with a getter and a child class extends the property with a setter.
• Fixed bug that led to an incorrect type evaluation when a list comprehension expression is used with bidirectional type inference and the expected type includes a type variable.
• Fixed bug that led to a false positive error when a __getitem__ returns Self.
• Fixed a bug that led to a false positive when determining the type compatibility of two TypedDict definitions whose keys were typed with unions that included two other (compatible) TypedDict definitions.

• Enhanced reportInvalidTypeVarUsage diagnostic message to include a recommended fix.
• Added check for the use of a bare Literal (with no type arguments) in places where it's not allowed.

Behavior Change:

• Adjusted heuristic for reportInvalidTypeVarUse so it doesn't emit a warning when an unbound TypeVar is used within a subscript.

Published 1.1.336

Bug Fixes:

• Fixed bug that results in an incorrect type evaluation when functools.partial is used with a constructor where type[Self] is passed as the first argument.
• Fixed bug that resulted in a crash during type analysis.
• Fixed bug that results in false positive when indexing an enum class.
• Fixed a bug that led to a false positive error when calling the same generic function multiple times in a call expression. This bug specifically affected the case where the generic function used PEP 695 syntax.

• Fixed bug in the import resolver that allowed typeshed stubs and stub files within installed third-party libraries to take precedence over local modules.
• Fixed a bug that leads an incorrect type evaluation when binding a magic method (like __add__) to self when the magic method returns Self.

• Fixed a bug that leads to a false positive reportPrivateUsage diagnostic when importing a public symbol from a "py.typed" library if that symbol is imported from a private symbol (and re-exported publicly) within the library.
• Fixed a bug that led to incorrect type evaluation when an inferred method return type includes a union where the subtypes are conditioned on constraints of a constrained TypeVar that parameterizes the class. In this case, one or more of these subtypes should be eliminated when a specialized class is bound to the method.
• Add support non english works in docstring arguments.
• Fix bug in the contravariant return type check where a contravariant used in a union was not reported.

Behavior Changes:

• Changed behavior when converting a class to a callable. If the class has no __init__ or __new__ method in its class hierarchy (other than those provided by object), pyright previously converted the constructor to a signature of (*args: Any, **kwargs: Any). It now converts it to a signature of () (i.e. no params) unless it's a type[T] or a protocol class.
• Modified the isinstance type narrowing logic to retain a TypeVar when narrowing in the positive case and the value is not a constrained TypeVar.

Enhancements:

• Added "metacls" as an allowed name for the "cls" parameter in a metaclass __new__ method.
• Improved pyright's enforcement of keyword arguments passed within a class statement when the class has no custom metaclass or __init_subclass__ in its hierarchy. In this case, the object.__init_subclass__ method applies, and it accepts no additional keyword arguments. Also improved the error reporting for __init_subclass__ in general.
• Improved handling of + operator when both operands are tuples. It now produces a more accurate type when one (but not both) of the two tuples is of indeterminate length.
• Updated typeshed stubs to the latest version.
• Added code to CLI to verify file specs passed on the command line. If they don't exist, emit an error and a non-zero exit code.
• Improved check for second argument to isinstance and issubclass so non-runtime-checkable protocol classes are rejected.
• Added special-case handling x in y narrowing logic for the case where x is a dict or Mapping and y is an iterable of TypedDicts.
• Added check for the use of contravariant TypeVars in an inferred return type.

Published 1.1.335

• Fixed bug that led to a false positive when assigning a lambda with *args to a callable type that doesn't contain *args.
• Fixed a few places where union order resulted in different type evaluation behaviors.
• Fixed a bug that led to a false positive error when specializing a type alias consisting of a callable parameterized by a TypeVarTuple.
• Fixed bug that causes a false positive MRO error when creating a subclass of a generic TypedDict and another TypedDict.
• Fixed a bug that results in incorrect type evaluation of a call expression when the callee is a function parameterized by a TypeVarTuple that has been specialized with a concatenation form.
• Fixed several bugs in the signature help provider when handling **kwargs parameters typed with an unpacked TypeDict (PEP 692).
• Added missing check described in PEP 692 where fields within an unpacked TypedDict used for **kwargs cannot overlap other keyword parameters in the same signature.
• Fixed a false positive reportIncompatibleMethodOverride error under certain circumstances where an overloaded method overrides another overloaded method.
• Fixed a bug that resulted in incorrect type evaluation when using a TypeVarTuple within a nested Callable type (i.e. a Callable that takes a Callable as a parameter).
• Fixed bug that resulted in false positive reportIncompatibleMethodOverload error under certain circumstances.
• Fixed a bug that causes a false positive reportUnnecessaryContains error when self is used on the LHS of the in operator within an enum class.
• Fixed bug that led to a false negative when assigning type Class to Self@Class.
• (Contribution by @JelleZijlstra) Fix missing space after "not" unary operator for expressions printed in output of reveal_type.
• Fixed bug in completion provider that resulted in an attempt to tokenize and parse a binary (native) library file. This led to a crash in some cases.
• Fixed a bug that results in a false positive error when a __new__ method returns Self for a generic class and the type variable is invariant.
• Fixed a bug that led to incorrect type narrowing for the x is None in the negative (else) case when x is a bound TypeVar (or Self).

Enhancements:

• Improved error message for descriptor accesses where binding or type validation fails for the __get__, __set__ or __delete__ methods.
• Added missing error check for zero-argument form of super() when used within a static method.
• Improved error message for member accesses.
• Improved diagnostic message for method overrides based on keyword/position-only parameter mismatch.
• Enhanced the handling of zero-argument form of super() to support the case where the containing method's self or cls parameter is annotated using a protocol. This can be used to handle mixin methods that call super().
• Added support for boolean values in diagnosticSeverityOverrides language server setting.

Other Changes:

• Updated heuristics for constructor evaluation to accommodate a wider range of types returned by the __new__ method. Previously, if the __new__ return type was anything other than a class instance, the heuristics assumed it wasn't intended and assumed that __new__ returned an instance of its class, as is usually the case.
• Restored previous behavior (prior to 1.1.334) where an instance of a class that derives from Any will not be considered type compatible with None.
• Significant rewrite of code that handles member accesses on class objects and class instances. This should improve internal consistency and fix many edge-case bugs. Due to the extent of this change, some regressions may result.

Bug Fix: Fixed bug that led to false negative when evaluating a call to a function with a recursive ParamSpec.

Bug Fix: Fixed a bug in the type guard logic for simple truthy/falsy checks. If the type is an instance of object or a TypeVar with no bound (which is treated like an object), the logic should not assume that it will always evaluate to truthy.

Published 1.1.333

Bug Fix: Fixed a bug that resulted in a false negative when assigning one TypedDict to another TypedDict. Field types should be treated as invariant rather than covariant because they are mutable (unless marked readonly).

Bug Fix: Fixed a recent regression that led to a false positive error when a class uses a custom metaclass that supplies a __setattr__ method.

Enhancement: Improved type narrowing in the negative case for isinstance when the filter type (the second argument) is type[T] (where T is a type variable) and the first argument is of type T. In this case, we can eliminate (filter) T in the negative case.

Bug Fix: Fixed a recent regression in the overload matching behavior that broke two tests in the pandas-stubs test suite.

Bug Fix: Fixed a bug that resulted in a false positive in certain circumstances where a lambda included simple math operations with integer literals. The fix requires disabling literal math within lambdas, since they are often used as callbacks that are called repeatedly in a loop.

Bug Fix: Reverted a portion of the recent changes designed to differentiate between a float that is really a float or a float that can also be an int. This resulted in false positives when inferring types using float literals.

Bug Fix: Fixed a false positive due to incorrect type narrowing logic when a del statement targets a specific element within a list (e.g. del my_list[1]).

Behavior Change: Changed the default Python version (the version that is assumed by pyright if it has no other context) from 3.11 to 3.12 now that 3.12 is final.

Enhancement: Improved diagnostic for the situation where overload matching fails to find any applicable overloads.

Bug Fix: Fixed a bug that resulted in incorrect type evaluation when an async function with an inferred return type is decorated with a class or function that uses a ParamSpec (such as functools.wraps).

Bug Fix: Fixed a bug that led to a false positive error when using a single-quote form of a format string that uses a format specifier expression. This is also a bug in the Python 3.12 interpreter that is being fixed.
