Bump attrs from 20.1.0 to 20.2.0

[dependabot-preview]

Bumps attrs from 20.1.0 to 20.2.0.

Release notes

Sourced from attrs's releases.

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 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.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.

  Therefore the inherited attribute will now be ignored when hashing and comparing instances of attr.Attribute. #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

• 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
