- Update to 23.1.0:
# Backwards-incompatible Changes
* Python 3.6 has been dropped and packaging switched to static
package data using Hatch. #993
# Deprecations
* The support for zope-interface via the attrs.validators.provides
validator is now deprecated and will be removed in, or after,
April 2024.
* The presence of a C-based package in our developement dependencies
has caused headaches and we're not under the impression it's used
a lot.
* Let us know if you're using it and we might publish it as a
separate package. #1120
# Changes
* attrs.filters.exclude() and attrs.filters.include() now support
the passing of attribute names as strings. #1068
* attrs.has() and attrs.fields() now handle generic classes
correctly. #1079
* Fix frozen exception classes when raised within e.g.
contextlib.contextmanager, which mutates their __traceback__
attributes. #1081
* @frozen now works with type checkers that implement PEP-681 (ex.
pyright). #1084
* Restored ability to unpickle instances pickled before 22.2.0.
#1085
* attrs.asdict()'s and attrs.astuple()'s type stubs now accept the
attrs.AttrsInstance protocol. #1090
* Fix slots class cellvar updating closure in CPython 3.8+ even when
__code__ introspection is unavailable. #1092
* attrs.resolve_types() can now pass include_extras to
typing.get_type_hints() on Python 3.9+, and does so by default.
#1099
* Added instructions for pull request workflow to CONTRIBUTING.md.
#1105
* Added type parameter to attrs.field() function for use with
attrs.make_class().
* Please note that type checkers ignore type metadata passed into
make_class(), but it can be useful if you're wrapping attrs. #1107
* It is now possible for attrs.evolve() (and attr.evolve()) to
change fields named inst if the instance is passed as a positional
argument.
* Passing the instance using the inst keyword argument is now
deprecated and will be removed in, or after, April 2024. #1117
* attrs.validators.optional() now also accepts a tuple of validators
(in addition to lists of validators). #1122
