Backwards-incompatible Changes

• Class-level kw_only=True behavior is now consistent with dataclasses.

  Previously, a class that sets kw_only=True makes all attributes keyword-only, including those from base classes.
  If an attribute sets kw_only=False, that setting is ignored, and it is still made keyword-only.

  Now, only the attributes defined in that class that doesn't explicitly set kw_only=False are made keyword-only.

  This shouldn't be a problem for most users, unless you have a pattern like this:

  @​attrs.define(kw_only=True)
  class Base:
      a: int
      b: int = attrs.field(default=1, kw_only=False)
  
  @​attrs.define
  class Subclass(Base):
      c: int

  Here, we have a kw_only=True attrs class (Base) with an attribute that sets kw_only=False and has a default (Base.b), and then create a subclass (Subclass) with required arguments (Subclass.c).
  Previously this would work, since it would make Base.b keyword-only, but now this fails since Base.b is positional, and we have a required positional argument (Subclass.c) following another argument with defaults.

Changes

• Values passed to the __init__() method of attrs classes are now correctly passed to __attrs_pre_init__() instead of their default values (in cases where kw_only was not specified).
  #​1427

• Added support for Python 3.14 and PEP 749.
  #​1446,
  #​1451

• attrs.validators.deep_mapping() now allows to leave out either key_validator xor value_validator.
  #​1448

• attrs.validators.deep_iterator() and attrs.validators.deep_mapping() now accept lists and tuples for all validators and wrap them into a attrs.validators.and_().
  #​1449

• Added a new experimental way to inspect classes:

  attrs.inspect(cls) returns the effective class-wide parameters that were used by attrs to construct the class.

  The returned class is the same data structure that attrs uses internally to decide how to construct the final class.
  #​1454

• Fixed annotations for attrs.field(converter=...).
  Previously, a tuple of converters was only accepted if it had exactly one element.
  #​1461

• The performance of attrs.asdict() has been improved by 45–260%.
  #​1463

• The performance of attrs.astuple() has been improved by 49–270%.
  #​1469

• The type annotation for attrs.validators.or_() now allows for different types of validators.

  This was only an issue on Pyright.
