I’m happy to announce a new release of attrs! attrs is the direct ancestor of – and the inspiration for – dataclasses in the standard library and remains the more powerful toolkit for creating regular classes without getting bogged down with writing repetitive boilerplate code: <https://www.attrs.org/>
My heartfelt thanks go to: - My generous GitHub sponsors <https://github.com/sponsors/hynek>, - companies subscribing to attrs on Tidelift <https://tidelift.com/subscription/pkg/pypi-attrs>, - and people who buy me coffees on <https://ko-fi.com/the_hynek>! ❤️ That's the support that made me maintain attrs since 2015 with no end in sight! ❤️ ------------------------------------------------------------------------ (alternatively, see <https://github.com/python-attrs/attrs/releases> for a richer-formatted version of the following) Highlights The main features of this release are: - The departure of Python 2.7 (enjoy your retirement!), - and the arrival of Python 3.11. We had loftier goals feature-wise, but didn't want to block others embracing Python 3.11. Full Changelog 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 - 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 Changes - Instantiation of frozen slotted classes is now faster. #898 - If an eq key is defined, it is also used before hashing the attribute. #909 - Added attrs.validators.min_len(). #916 - attrs.validators.deep_iterable()'s member_validator argument now also accepts a list of validators and wraps them in an attrs.validators.and_(). #925 - Added missing type stub re-imports for attrs.converters and attrs.filters. #931 - Added missing stub for attr(s).cmp_using(). #949 - attrs.validators._in()'s ValueError is not missing the attribute, expected options, and the value it got anymore. #951 - Python 3.11 is now officially supported. #969 _______________________________________________ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com
