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
^^^^^^^

`898 <https://github.com/python-attrs/attrs/issues/898>`_

- Added ``attrs.validators.min_len()``.
`916 <https://github.com/python-attrs/attrs/issues/916>`_

- Added missing type stub re-imports for ``attrs.converters`` and ``attrs.filters``.
`931 <https://github.com/python-attrs/attrs/issues/931>`_

`949 <https://github.com/python-attrs/attrs/issues/949>`_
