Release Notes
python-attrs/attrs (attrs)
v24.2.0
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 forattrs.field()
's /attr.ib()
's converter argument) works again when passingattrs.setters.convert
to on_setattr (which is default forattrs.define
). #1328 - Restored support for PEP 649 / 749-implementing Pythons -- currently 3.14-dev. #1329
v24.1.0
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 theattr
andattrs
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, likefloat('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
, andmake_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. Allowsuper()
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 withfunctools.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 thatattrs.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
