attrs v21.2.0 Release Notes

Release Date: 2021-05-07 // almost 3 years ago

  • Backward-incompatible Changes

    • ⏪ We had to revert the recursive feature for attr.evolve() because it broke some use-cases -- sorry! #806 <https://github.com/python-attrs/attrs/issues/806>_
    • 📇 Python 3.4 is now blocked using packaging metadata because attrs can't be imported on it anymore. To ensure that 3.4 users can keep installing attrs easily, we will yank <https://pypi.org/help/#yanked>_ 21.1.0 from PyPI. This has no consequences if you pin attrs to 21.1.0. #807 <https://github.com/python-attrs/attrs/issues/807>_
