Changelog

52.0.0

-------


Breaking Changes
^^^^^^^^^^^^^^^^
* 2537: Remove fallback support for fetch_build_eggs using easy_install. Now pip is required for setup_requires to succeed.
* 2544: Removed 'easy_install' top-level model (runpy entry point) and 'easy_install' console script.
* 2545: Removed support for eggsecutables.

Changes
^^^^^^^
* 2459: Tests now run in parallel via pytest-xdist, completing in about half the time. Special thanks to :user:`webknjaz` for hard work implementing test isolation. To run without parallelization, disable the plugin with ``tox -- -p no:xdist``.
