Release Notes

python-attrs/attrs (attrs)

v26.1.0

Compare Source

Backwards-incompatible Changes

• Field aliases are now resolved before calling field_transformer, so transformers receive fully populated Attribute objects with usable alias values instead of None.
  The new Attribute.alias_is_default flag indicates whether the alias was auto-generated (True) or explicitly set by the user (False).
  #​1509

Changes

• Fix type annotations for attrs.validators.optional(), so it no longer rejects tuples with more than one validator.
  #​1496
• The attrs.validators.disabled() contextmanager can now be nested.
  #​1513
• Frozen classes can set on_setattr=attrs.setters.NO_OP in addition to None.
  #​1515
• It's now possible to pass attrs instances in addition to attrs classes to attrs.fields().
  #​1529

v25.4.0

Compare Source

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.
  #​1457

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.
  #​1474

v25.3.0

Compare Source

Changes

• Restore support for generator-based field_transformers.
  #​1417

v25.2.0

Compare Source

Changes

• Checking mandatory vs non-mandatory attribute order is now performed after the field transformer, since the field transformer may change attributes and/or their order.
  #​1147
• attrs.make_class() now allows for Unicode class names.
  #​1406
• Speed up class creation by 30%-50% by compiling methods only once and using a variety of other techniques.
  #​1407
• The error message if an attribute has both an annotation and a type argument will now disclose what attribute seems to be the problem.
  #​1410

v25.1.0

Compare Source

Changes

• This release only ensures correct PyPI licensing metadata.
  #​1386

v24.3.0

Compare Source

Backwards-incompatible Changes

• Python 3.7 has been dropped.
  #​1340

Changes

• Introduce attrs.NothingType, for annotating types consistent with attrs.NOTHING.
  #​1358
• Allow mutating __suppress_context__ and __notes__ on frozen exceptions.
  #​1365
• attrs.converters.optional() works again when taking attrs.converters.pipe() or another Converter as its argument.
  #​1372
• attrs instances now support copy.replace().
  #​1383
• attrs.validators.instance_of()'s type hints now allow for union types.
  For example: instance_of(str | int)
  #​1385

v24.2.0

Compare Source

Deprecations

• Given the amount of warnings raised in the broader ecosystem, we've decided to only soft-deprecate the hash argument to @define / @attr.s.
  Please don't use it in new code, but we don't intend to remove it anymore.
  #​1330

Changes

• attrs.converters.pipe() (and its syntactic sugar of passing a list for attrs.field()'s / attr.ib()'s converter argument) works again when passing attrs.setters.convert to on_setattr (which is default for attrs.define).
  #​1328
• Restored support for PEP 649 / 749-implementing Pythons -- currently 3.14-dev.
  #​1329

v24.1.0

Compare Source

Backwards-incompatible Changes

• attrs.evolve() doesn't accept the inst argument as a keyword argument anymore.
  Pass it as the first positional argument instead.
  #​1264

• attrs.validators.provides() has been removed.
  The removed code is available as a gist for convenient copy and pasting.
  #​1265

• All packaging metadata except from __version__ and __version_info__ has been removed from the attr and attrs modules (for example, attrs.__url__).

  Please use importlib.metadata or importlib-metadata instead.
  #​1268

• The generated __eq__ methods have been sped up significantly by generating a chain of attribute comparisons instead of constructing and comparing tuples.
  This change arguably makes the behavior more correct,
  but changes it if an attribute compares equal by identity but not value, like float('nan').
  #​1310

Deprecations

• The repr_ns argument to attr.s is now deprecated.
  It was a workaround for nested classes in Python 2 and is pointless in Python 3.
  #​1263
• The hash argument to @attr.s, @attrs.define, and make_class() is now deprecated in favor of unsafe_hash, as defined by PEP 681.
  #​1323

Changes

• Allow original slotted functools.cached_property classes to be cleaned by garbage collection.
  Allow super() calls in slotted cached properties.
  #​1221

• Our type stubs now use modern type notation and are organized such that VS Code's quick-fix prefers the attrs namespace.
  #​1234

• Preserve AttributeError raised by properties of slotted classes with functools.cached_properties.
  #​1253

• It is now possible to wrap a converter into an attrs.Converter and get the current instance and/or the current field definition passed into the converter callable.

  Note that this is not supported by any type checker, yet.
  #​1267

• attrs.make_class() now populates the __annotations__ dict of the generated class, so that attrs.resolve_types() can resolve them.
  #​1285

• Added the attrs.validators.or_() validator.
  #​1303

• The combination of a __attrs_pre_init__ that takes arguments, a kw-only field, and a default on that field does not crash anymore.
  #​1319

• attrs.validators.in_() now transforms certain unhashable options to tuples to keep the field hashable.

  This allows fields that use this validator to be used with, for example, attrs.filters.include().
  #​1320

• If a class has an inherited method called __attrs_init_subclass__, it is now called once the class is done assembling.

  This is a replacement for Python's __init_subclass__ and useful for registering classes, and similar.
  #​1321
