<blockquote>
<h2>Version 7.3.0 — 2023-08-12</h2>
<ul>
<li>
<p>Added a :meth:<code>.Coverage.collect</code> context manager to start
and stop coverage
data collection.</p>
</li>
<li>
<p>Dropped support for Python 3.7.</p>
</li>
<li>
<p>Fix: in unusual circumstances, SQLite cannot be set to asynchronous
mode.
Coverage.py would fail with the error <code>Safety level may not be
changed inside a transaction.</code> This is now avoided, closing
<code>issue 1646</code>_. Thanks
to Michael Bell for the detailed bug report.</p>
</li>
<li>
<p>Docs: examples of configuration files now include separate examples
for the
different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and
tox.ini.</p>
</li>
<li>
<p>Fix: added <code>nosemgrep</code> comments to our JavaScript code so
that
semgrep-based SAST security checks won't raise false alarms about
security
problems that aren't problems.</p>
</li>
<li>
<p>Added a CITATION.cff file, thanks to <code>Ken Schackart &lt;pull
1641_&gt;</code>_.</p>
</li>
