<blockquote>
<h2>Version 7.9.1 — 2025-06-13</h2>
<ul>
<li>
<p>The &quot;no-ctracer&quot; warning is not issued for Python
pre-release versions.
Coverage doesn't ship compiled wheels for those versions, so this was
far too
noisy.</p>
</li>
<li>
<p>On Python 3.14+, the &quot;sysmon&quot; core is now the default if
it's supported for
your configuration. Plugins and dynamic contexts are still not supported
with it.</p>
</li>
</ul>
