Backwards-incompatible Changes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Python 2.7 is not supported anymore.

Dealing with Python 2.7 tooling has become too difficult for a volunteer-run project.

We have supported Python 2 more than 2 years after it was officially discontinued and feel that we have paid our dues. All version up to 21.4.0 from December 2021 remain fully functional, of course. #936 <https://github.com/python-attrs/attrs/issues/936>_
The deprecated cmp attribute of attrs.Attribute has been removed. This does not affect the cmp argument to attr.s that can be used as a shortcut to set eq and order at the same time. #939 <https://github.com/python-attrs/attrs/issues/939>_

Changes ^^^^^^^

Instantiation of frozen slotted classes is now faster. #898 <https://github.com/python-attrs/attrs/issues/898>_
If an eq key is defined, it is also used before hashing the attribute. #909 <https://github.com/python-attrs/attrs/issues/909>_
Added attrs.validators.min_len(). #916 <https://github.com/python-attrs/attrs/issues/916>_
attrs.validators.deep_iterable()'s member_validator argument now also accepts a list of validators and wraps them in an attrs.validators.and_(). #925 <https://github.com/python-attrs/attrs/issues/925>_
Added missing type stub re-imports for attrs.converters and attrs.filters. #931 <https://github.com/python-attrs/attrs/issues/931>_
Added missing stub for attr(s).cmp_using(). #949 <https://github.com/python-attrs/attrs/issues/949>_
attrs.validators._in()'s ValueError is not missing the attribute, expected options, and the value it got anymore. #951 <https://github.com/python-attrs/attrs/issues/951>_
Python 3.11 is now officially supported. #969 <https://github.com/python-attrs/attrs/issues/969>_

`v21.4.0`

Compare Source

Changes ^^^^^^^

Fixed the test suite on PyPy3.8 where cloudpickle does not work. #892 <https://github.com/python-attrs/attrs/issues/892>_
Fixed coverage report for projects that use attrs and don't set a --source. #895 <https://github.com/python-attrs/attrs/issues/895>*, #896 <https://github.com/python-attrs/attrs/issues/896>*

`v21.3.0`

Compare Source

Backward-incompatible Changes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When using @define, converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is on_setattr=[attrs.setters.convert, attrs.setters.validate].

This is unfortunately a breaking change, but it was an oversight, impossible to raise a DeprecationWarning about, and it's better to fix it now while the APIs are very fresh with few users. #835 <https://github.com/python-attrs/attrs/issues/835>*, #886 <https://github.com/python-attrs/attrs/issues/886>*
import attrs has finally landed! As of this release, you can finally import attrs using its proper name.

Not all names from the attr namespace have been transferred; most notably attr.s and attr.ib are missing. See attrs.define and attrs.field if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found On The Core API Names <https://www.attrs.org/en/latest/names.html>_

This feature is at least for one release provisional. We don't plan on changing anything, but such a big change is unlikely to go perfectly on the first strike.

The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have not moved -- or even removed -- anything from attr!

Please do report any bugs or documentation inconsistencies! #887 <https://github.com/python-attrs/attrs/issues/887>_

Changes ^^^^^^^

attr.asdict(retain_collection_types=False) (default) dumps collection-esque keys as tuples. #646 <https://github.com/python-attrs/attrs/issues/646>*, #888 <https://github.com/python-attrs/attrs/issues/888>*
__match_args__ are now generated to support Python 3.10's Structural Pattern Matching <https://docs.python.org/3.10/whatsnew/3.10.html#pep-634-structural-pattern-matching>*. This can be controlled by the match_args argument to the class decorators on Python 3.10 and later. On older versions, it is never added and the argument is ignored. #815 <https://github.com/python-attrs/attrs/issues/815>*
If the class-level on_setattr is set to attrs.setters.validate (default in @define and @mutable) but no field defines a validator, pretend that it's not set. #817 <https://github.com/python-attrs/attrs/issues/817>_
The generated __repr__ is significantly faster on Pythons with f-strings. #819 <https://github.com/python-attrs/attrs/issues/819>_
Attributes transformed via field_transformer are wrapped with AttrsClass again. #824 <https://github.com/python-attrs/attrs/issues/824>_
Generated source code is now cached more efficiently for identical classes. #828 <https://github.com/python-attrs/attrs/issues/828>_
Added attrs.converters.to_bool(). #830 <https://github.com/python-attrs/attrs/issues/830>_
attrs.resolve_types() now resolves types of subclasses after the parents are resolved. #842 <https://github.com/python-attrs/attrs/issues/842>_ #843 <https://github.com/python-attrs/attrs/issues/843>_
Added new validators: lt(val) (< val), le(va) (≤ val), ge(val) (≥ val), gt(val) (> val), and maxlen(n). #845 <https://github.com/python-attrs/attrs/issues/845>_
attrs classes are now fully compatible with cloudpickle <https://github.com/cloudpipe/cloudpickle>_ (no need to disable repr anymore). #857 <https://github.com/python-attrs/attrs/issues/857>_
Added new context manager attrs.validators.disabled() and functions attrs.validators.(set|get)_disabled(). They deprecate attrs.(set|get)_run_validators(). All functions are interoperable and modify the same internal state. They are not – and never were – thread-safe, though. #859 <https://github.com/python-attrs/attrs/issues/859>_
attrs.validators.matches_re() now accepts pre-compiled regular expressions in addition to pattern strings. #877 <https://github.com/python-attrs/attrs/issues/877>_

`v21.2.0`

Compare Source

Backward-incompatible Changes ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

We had to revert the recursive feature for attr.evolve() because it broke some use-cases -- sorry! #806 <https://github.com/python-attrs/attrs/issues/806>_
Python 3.4 is now blocked using packaging metadata because attrs can't be imported on it anymore. To ensure that 3.4 users can keep installing attrs easily, we will yank <https://pypi.org/help/#yanked>_ 21.1.0 from PyPI. This has no consequences if you pin attrs to 21.1.0. #807 <https://github.com/python-attrs/attrs/issues/807>_

`v21.1.0`

Compare Source

Deprecations ^^^^^^^^^^^^

The long-awaited, much-talked-about, little-delivered import attrs is finally upon us!

Since the NG APIs have now been proclaimed stable, the next release of attrs will allow you to actually import attrs. We're taking this opportunity to replace some defaults in our APIs that made sense in 2015, but don't in 2021.

So please, if you have any pet peeves about defaults in attrs's APIs, now is the time to air your grievances in #487! We're not gonna get such a chance for a second time, without breaking our backward-compatibility guarantees, or long deprecation cycles. Therefore, speak now or forever hold you peace! #487 <https://github.com/python-attrs/attrs/issues/487>_
The cmp argument to attr.s() and attr.ib() has been undeprecated It will continue to be supported as syntactic sugar to set eq and order in one go.

I'm terribly sorry for the hassle around this argument! The reason we're bringing it back is it's usefulness regarding customization of equality/ordering.

The cmp attribute and argument on attr.Attribute remains deprecated and will be removed later this year. #773 <https://github.com/python-attrs/attrs/issues/773>_

Changes ^^^^^^^

It's now possible to customize the behavior of eq and order by passing in a callable. #435 <https://github.com/python-attrs/attrs/issues/435>*, #627 <https://github.com/python-attrs/attrs/issues/627>*
The instant favorite next-generation APIs are not provisional anymore!

They are also officially supported by Mypy as of their 0.800 release <https://mypy-lang.blogspot.com/2021/01/mypy-0800-released.html>_.

We hope the next release will already contain an (additional) importable package called attrs. #668 <https://github.com/python-attrs/attrs/issues/668>*, #786 <https://github.com/python-attrs/attrs/issues/786>*
If an attribute defines a converter, the type of its parameter is used as type annotation for its corresponding __init__ parameter.

If an attr.converters.pipe is used, the first one's is used. #710 <https://github.com/python-attrs/attrs/issues/710>_
Fixed the creation of an extra slot for an attr.ib when the parent class already has a slot with the same name. #718 <https://github.com/python-attrs/attrs/issues/718>_
__attrs__init__() will now be injected if init=False, or if auto_detect=True and a user-defined __init__() exists.

This enables users to do "pre-init" work in their __init__() (such as super().__init__()).

__init__() can then delegate constructor argument processing to self.__attrs_init__(*args, **kwargs). #731 <https://github.com/python-attrs/attrs/issues/731>_
bool(attr.NOTHING) is now False. #732 <https://github.com/python-attrs/attrs/issues/732>_
It's now possible to use super() inside of properties of slotted classes. #747 <https://github.com/python-attrs/attrs/issues/747>_
Allow for a __attrs_pre_init__() method that -- if defined -- will get called at the beginning of the attrs-generated __init__() method. #750 <https://github.com/python-attrs/attrs/issues/750>_
Added forgotten attr.Attribute.evolve() to type stubs. #752 <https://github.com/python-attrs/attrs/issues/752>_
attrs.evolve() now works recursively with nested attrs classes. #759 <https://github.com/python-attrs/attrs/issues/759>_
Python 3.10 is now officially supported. #763 <https://github.com/python-attrs/attrs/issues/763>_
attr.resolve_types() now takes an optional attrib argument to work inside a field_transformer. #774 <https://github.com/python-attrs/attrs/issues/774>_
ClassVar\ s are now also detected if they come from typing-extensions <https://pypi.org/project/typing-extensions/>*. #782 <https://github.com/python-attrs/attrs/issues/782>*
To make it easier to customize attribute comparison (#435), we have added the attr.cmp_with() helper.

See the new docs on comparison <https://www.attrs.org/en/stable/comparison.html>_ for more details. #787 <https://github.com/python-attrs/attrs/issues/787>_
Added provisional support for static typing in pyright via the dataclass_transforms specification <https://github.com/microsoft/pyright/blob/main/specs/dataclass_transforms.md>_. Both the pyright specification and attrs implementation may change in future versions of both projects.

Your constructive feedback is welcome in both attrs#795 <https://github.com/python-attrs/attrs/issues/795>_ and pyright#1782 <https://github.com/microsoft/pyright/discussions/1782>*. #796 <https://github.com/python-attrs/attrs/issues/796>*
