python-attrs/attrs 24.2.0

on GitHub

Highlights

Big releases always carry the risk of regressions, but never did I expect to break Python 3.14’s CI! On the plus side, attrs runs on 3.14 now.

Full Changelog

Deprecations

• Given the amount of warnings raised in the broader ecosystem, we've decided to only soft-deprecate the hash argument to @define / @attr.s. Please don't use it in new code, but we don't intend to remove it anymore. #1330

Changes

• attrs.converters.pipe() (and its syntactic sugar of passing a list for attrs.field()'s / attr.ib()'s converter argument) works again when passing attrs.setters.convert to on_setattr (which is default for attrs.define). #1328
• Restored support for PEP 649 / 749-implementing Pythons -- currently 3.14-dev. #1329
