Release Notes

pytest-dev/pytest-xdist

### [`v3.3.1`](https://togithub.com/pytest-dev/pytest-xdist/blob/HEAD/CHANGELOG.rst#pytest-xdist-331-2023-05-19) [Compare Source](https://togithub.com/pytest-dev/pytest-xdist/compare/v3.3.0...v3.3.1) \=============================== ## Bug Fixes - `#​907 `\_: Avoid remote calls during startup as `execnet` by default does not ensure remote affinity with the main thread and might accidentally schedule the pytest worker into a non-main thread, which breaks numerous frameworks, for example `asyncio`, `anyio`, `PyQt/PySide`, etc. A more safe correction will require thread affinity in `execnet` (`pytest-dev/execnet#​96 `\__).
