<p>[!WARNING]</p>
<p><strong>Material for MkDocs is approaching end of life</strong></p>
<p>Material for MkDocs is scheduled to reach end of life on November 5,
2026. Until then, maintenance is limited to critical bug fixes and
security updates. After this date, the project will remain available on
PyPI and GitHub, but no further maintenance is planned except in
exceptional circumstances.</p>
<p>For users looking for a long-term, actively developed successor,
we're building <a href="https://zensical.org">Zensical</a> – a
next-generation static site generator designed for technical
documentation. If you're planning a new documentation project or
evaluating your long-term options, we invite you to take a look.</p>
<p>Organizations requiring support beyond this date are welcome to get
in touch to discuss available options.</p>
