The pytest team is proud to announce the 4.0.0 release! This version is near identical to 3.10 feature-wise, except now pytest's own deprecated features generate errors, but they can be turned back into warnings as a stop gap measure until 4.1. Users are *strongly* encouraged to take a look at the CHANGELOG for instructions and rationale about the deprecated functionality: https://docs.pytest.org/en/latest/changelog.html For complete documentation, please visit: https://docs.pytest.org/en/latest/ As usual, you can upgrade from PyPI via: pip install -U pytest Thanks to all who contributed to this release! Happy testing, The Pytest Development Team
