<h2>v4.7.0 (2023-08-08)</h2>
<p>Features - 4.7.0</p>
<pre><code>- Make --hashseed default to PYTHONHASHSEED, if defined - by
:user:`paravoid`.
The main motivation for this is to able to set the hash seed when
building the
documentation with &quot;tox -e docs&quot;, and thus avoid embedding a
random value in
the tox documentation for --help. This caused documentation builds to
fail to
  build reproducibly. (:issue:`2942`)
<p>Bugfixes - 4.7.0
</code></pre></p>
<ul>
<li>Update a regular expression in tests to match the exception message
in both Python 3.12 and older. (:issue:<code>3065</code>)</li>
</ul>
<p>Improved Documentation - 4.7.0</p>
<pre><code>- Fix broken links - by :user:`gaborbernat`. (:issue:`3072`)
