<blockquote>
<h1>pytest-xdist 3.5.0 (2023-11-21)</h1>
<h2>Features</h2>
<ul>
<li><code>[#632](https://github.com/pytest-dev/pytest-xdist/issues/632)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/632&gt;</code>_:
<code>--dist=loadscope</code> now sorts scopes by number of tests to
assign largest scopes early -- in many cases this should improve overall
test session running time, as there is less chance of a large scope
being left to be processed near the end of the session, leaving other
workers idle.</li>
</ul>
<h1>pytest-xdist 3.4.0 (2023-11-11)</h1>
<h2>Features</h2>
<ul>
<li>
<p><code>[#963](https://github.com/pytest-dev/pytest-xdist/issues/963)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/963&gt;</code>_:
Wait for workers to finish reporting when test run stops early.</p>
<p>This makes sure that the results of in-progress tests are displayed.
Previously these reports were being discarded, losing information about
the
test run.</p>
</li>
<li>
<p><code>[#965](https://github.com/pytest-dev/pytest-xdist/issues/965)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/965&gt;</code>_:
Added support for Python 3.12.</p>
</li>
</ul>
<h1>pytest-xdist 3.3.1 (2023-05-19)</h1>
<h2>Bug Fixes</h2>
<ul>
<li>
<p><code>[#907](https://github.com/pytest-dev/pytest-xdist/issues/907)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/907&gt;</code>_:
Avoid remote calls during startup as <code>execnet</code> 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 <code>asyncio</code>, <code>anyio</code>,
<code>PyQt/PySide</code>, etc.</p>
<p>A more safe correction will require thread affinity in
<code>execnet</code> (<code>pytest-dev/execnet#96
&lt;https://github.com/pytest-dev/execnet/issues/96&gt;</code>__).</p>
</li>
</ul>
<h1>pytest-xdist 3.3.0 (2023-05-12)</h1>
<h2>Features</h2>
<ul>
<li><code>[#555](https://github.com/pytest-dev/pytest-xdist/issues/555)
&lt;https://github.com/pytest-dev/pytest-xdist/issues/555&gt;</code>_:
Improved progress output when collecting nodes to be less verbose.</li>
</ul>
<h1>pytest-xdist 3.2.1 (2023-03-12)</h1>
