===============================

Bug Fixes

• #&#8203;907 <https://github.com/pytest-dev/pytest-xdist/issues/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#&#8203;96 <https://github.com/pytest-dev/execnet/issues/96>__).
