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.

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

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!

Changes

attr.asdict(retain_collection_types=False) (default) dumps collection-esque keys as tuples.
#646,
#888
__match_args__ are now generated to support Python 3.10's
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
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
The generated __repr__ is significantly faster on Pythons with f-strings.
#819
Attributes transformed via field_transformer are wrapped with AttrsClass again.
#824
Generated source code is now cached more efficiently for identical classes.
#828
Added attrs.converters.to_bool().
#830
attrs.resolve_types() now resolves types of subclasses after the parents are resolved.
#842
#843
Added new validators: lt(val) (< val), le(va) (≤ val), ge(val) (≥ val), gt(val) (> val), and maxlen(n).
#845
attrs classes are now fully compatible with cloudpickle (no need to disable repr anymore).
#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
attrs.validators.matches_re() now accepts pre-compiled regular expressions in addition to pattern strings.
