attr.define(), attr.frozen(), attr.mutable(), and attr.field() remain provisional.
This release does not change change anything about them and they are already used widely in production though.
If you wish to use them together with mypy, you can simply drop this plugin 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. #668
Changes
attr.s() now has a field_transformer hook that is called for all Attributes and returns a (modified or updated) list of Attribute instances. attr.asdict() has a value_serializer hook that can change the way values are converted. Both hooks are meant to help with data (de-)serialization workflows. #653
raise from now works on frozen classes on PyPy. #703, #712
attr.asdict() and attr.astuple() now treat frozensets like sets with regards to the retain_collection_types argument. #704
The type stubs for attr.s() and attr.make_class() are not missing the collect_by_mro argument anymore. #711
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.

Changes
attr.define() et al now correct detect __eq__ and __ne__. #671
attr.define() et al's hybrid behavior now also works correctly when arguments are passed. #675
It's possible to define custom __setattr__ methods on slotted classes again. #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.
attr.define(), attr.frozen(), attr.mutable(), and attr.field() remain provisional.
