<https://github.com/pytest-dev/pytest-xdist/issues/1071>`\_: Add

[`v3.6.0`](https://togithub.com/pytest-dev/pytest-xdist/blob/HEAD/CHANGELOG.rst#pytest-xdist-360-2024-04-19)

[Compare

\===============================

This release was YANKED due to a regression fixed in 3.6.1.

## Features

- `#&#8203;1027
<https://github.com/pytest-dev/pytest-xdist/pull/1027>`\_:`pytest-xdist`
workers now always execute the tests in the main thread.
Previously some tests might end up executing in a separate thread other
than `main` in the workers, due to some internal ` execnet`` details.
This can cause problems specially with async frameworks where the event
loop is running in the ``main`` thread (for example
`[#&#8203;620](https://togithub.com/pytest-dev/pytest-xdist/issues/620)
[#&#8203;620](https://togithub.com/pytest-dev/pytest-xdist/issues/620)\`\__).

## Bug Fixes

- `#&#8203;1024
<https://github.com/pytest-dev/pytest-xdist/issues/1024>`\_: Added
proper handling of `shouldstop` (such as set by `--max-fail`) and
`shouldfail` conditions in workers.
Previously, a worker might have continued executing further tests before
the controller could terminate the session.

- `#&#8203;1028
<https://github.com/pytest-dev/pytest-xdist/issues/1028>`\_: Fixed
compatibility issue between `looponfail` and editable installs.

- `#&#8203;620
<https://github.com/pytest-dev/pytest-xdist/issues/620>`\_: Use the new
`main_thread_only` `execnet` "execmodel" so that code which expects to
only run in the main thread will now work as expected.

- `#&#8203;937
<https://github.com/pytest-dev/pytest-xdist/issues/937>`\_: Fixed a bug
where plugin would raise an incompatibility error with `--pdb` despite
using `-n0`.

## Removals

- `#&#8203;1053
<https://github.com/pytest-dev/pytest-xdist/issues/1053>`\_: Dropped
support for Python 3.7.

- `#&#8203;1057
<https://github.com/pytest-dev/pytest-xdist/issues/1057>`\_:
pytest>=7.0.0 is now required.

    execnet>=2.1.0 is now required.

## Trivial Changes

- `#&#8203;1020
<https://github.com/pytest-dev/pytest-xdist/issues/1020>`\_:
pytest-xdist's `setup.py` file is removed.

If you relied on this file, e.g. to install pytest using `setup.py
install`,
please see `Why you shouldn't invoke setup.py directly
<https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary>`\_
for alternatives.

- `#&#8203;1057
<https://github.com/pytest-dev/pytest-xdist/issues/1057>`\_: The
internals of pytest-xdist are now fully typed. The typing is not exposed
yet.

- `#&#8203;996
<https://github.com/pytest-dev/pytest-xdist/issues/996>`\_: Adjusted
license file format and content to ensure security scanners will
identity the license.
