Add backward compatibility for deadlock issue with the
<code>execnet</code> new <code>main_thread_only</code>
&quot;execmodel&quot; triggered when pytest-cov accesses rinfo.</li>
</ul>
<h1>pytest-xdist 3.6.0 (2024-04-19)</h1>
<p>This release was YANKED due to a regression fixed in 3.6.1.</p>

<ul>

<li><code>[#1027](pytest-dev/pytest-xdist#1027)
&lt;https://github.com/pytest-dev/pytest-xdist/pull/1027&gt;</code>_:<code>pytest-xdist</code>
workers now always execute the tests in the main thread.
Previously some tests might end up executing in a separate thread other

&lt;https://github.com/pytest-dev/pytest-xdist/issues/1024&gt;</code>_:
Added proper handling of <code>shouldstop</code> (such as set by

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

<li>
<p><code>[#937](pytest-dev/pytest-xdist#937)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/937&gt;</code>_:

pytest-xdist's <code>setup.py</code> file is removed.</p>
<p>If you relied on this file, e.g. to install pytest using
<code>setup.py install</code>,
please see <code>Why you shouldn't invoke setup.py directly
&lt;https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary&gt;</code>_
