<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/pytest-dev/pytest-asyncio/releases">pytest-asyncio's
releases</a>.</em></p>
<blockquote>
<h2>pytest-asyncio v1.4.0</h2>
<h1><a
href="https://github.com/pytest-dev/pytest-asyncio/tree/1.4.0">1.4.0</a>
- 2026-05-26</h1>
<h2>Deprecated</h2>
<ul>
<li>Overriding the <em>event_loop_policy</em> fixture is deprecated. Use
the <code>pytest_asyncio_loop_factories</code> hook instead. (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1419">#1419</a>)</li>
</ul>
<h2>Added</h2>
<ul>
<li>
<p>Added the <code>pytest_asyncio_loop_factories</code> hook to
parametrize asyncio tests with custom event loop factories.</p>
<p>The hook returns a mapping of factory names to loop factories, and
<code>pytest.mark.asyncio(loop_factories=[...])</code> selects a subset
of configured factories per test. When a single factory is configured,
test names are unchanged.</p>
<p>Synchronous <code>@pytest_asyncio.fixture</code> functions now see
the correct event loop when custom loop factories are configured, even
when test code disrupts the current event loop (e.g., via
<code>asyncio.run()</code> or
<code>asyncio.set_event_loop(None)</code>). (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1164">#1164</a>)</p>
</li>
</ul>
<h2>Changed</h2>
<ul>
<li>Improved the readability of the warning message that is displayed
when <code>asyncio_default_fixture_loop_scope</code> is unset (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1298">#1298</a>)</li>
<li>Only import <code>asyncio.AbstractEventLoopPolicy</code> for type
checking to avoid raising
a DeprecationWarning. (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1394">#1394</a>)</li>
<li>Updated minimum supported pytest version to v8.4.0. (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1397">#1397</a>)</li>
</ul>
<h2>Fixed</h2>
<ul>
<li>Fixed a <code>ResourceWarning: unclosed event loop</code> warning
that could occur when a synchronous test called
<code>asyncio.run()</code> or otherwise unset the current event loop
after pytest-asyncio had run an async test or fixture. (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/724">#724</a>)</li>
</ul>
<h2>Notes for Downstream Packagers</h2>
<ul>
<li>Added dependency on <code>sphinx-tabs &gt;= 3.5</code> to organize
documentation examples into tabs. (<a
href="https://redirect.github.com/pytest-dev/pytest-asyncio/issues/1395">#1395</a>)</li>
</ul>
