<blockquote>
<h2>Version 7.2.6 — 2023-05-23</h2>
<ul>
<li>
<p>Fix: the <code>lcov</code> command could raise an IndexError
exception if a file is
translated to Python but then executed under its own name. Jinja2 does
this
when rendering templates.  Fixes <code>issue 1553</code>_.</p>
</li>
<li>
<p>Python 3.12 beta 1 now inlines comprehensions. Previously they were
compiled
as invisible functions and coverage.py would warn you if they weren't
completely executed.  This no longer happens under Python 3.12.</p>
</li>
<li>
<p>Fix: the <code>coverage debug sys</code> command includes some
environment variables
in its output. This could have included sensitive data. Those values are
now hidden with asterisks, closing <code>issue 1628</code>_.</p>
</li>
</ul>
