Changelog
### 20.2.0
```
-------------------
Backward-incompatible Changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- ``attr.define()``, ``attr.frozen()``, ``attr.mutable()``, and ``attr.field()`` remain **provisional**.
This release fixes a bunch of bugs and ergonomics but they remain mostly unchanged.
If you wish to use them together with mypy, you can simply drop `this plugin <https://gist.github.com/hynek/1e3844d0c99e479e716169034b5fa963file-attrs_ng_plugin-py>`_ into your project.
Feel free to provide feedback to them in the linked issue 668.
We will release the ``attrs`` namespace once we have the feeling that the APIs have properly settled.

Changes
^^^^^^^
- ``attr.define()`` et al now correct detect ``__eq__`` and ``__ne__``.
`671 <https://github.com/python-attrs/attrs/issues/671>`_
- ``attr.define()`` et al's hybrid behavior now also works correctly when arguments are passed.
`675 <https://github.com/python-attrs/attrs/issues/675>`_
- It's possible to define custom ``__setattr__`` methods on slotted classes again.
`681 <https://github.com/python-attrs/attrs/issues/681>`_
- In 20.1.0 we introduced the ``inherited`` attribute on the ``attr.Attribute`` class to differentiate attributes that have been inherited and those that have been defined directly on the class.
It has shown to be problematic to involve that attribute when comparing instances of ``attr.Attribute`` though, because when sub-classing, attributes from base classes are suddenly not equal to themselves in a super class.
Therefore the ``inherited`` attribute will now be ignored when hashing and comparing instances of ``attr.Attribute``.
`684 <https://github.com/python-attrs/attrs/issues/684>`_
- ``zope.interface`` is now a "soft dependency" when running the test suite; if ``zope.interface`` is not installed when running the test suite, the interface-related tests will be automatically skipped.
`685 <https://github.com/python-attrs/attrs/issues/685>`_
- The ergonomics of creating frozen classes using ``define(frozen=True)`` and sub-classing frozen classes has been improved:
you don't have to set ``on_setattr=None`` anymore.
`687 <https://github.com/python-attrs/attrs/issues/687>`_
