+Lesser General Public License (LGPL)</a>. This makes it free software

+<p>The expected audience of this website are</p>
+<ul>
+<li>security researches and</li>
+<li>open source package maintainers</li>
+</ul>
+<p>Security researches should be able to inspect the source code of
+older live555 releases, e.g. when they investigate an insecure hardware
+device that ships an out-of-date version of live555 and other
+software.</p>
+<p>When this site provides stable URLs, also package maintainers for
+Linux distributions, like Ubuntu or debian, and maintainers for embedded
+build systems, like <a href="https://openwrt.org/">openwrt</a>, <a
+href="https://buildroot.org/">buildroot</a> or <a
+href="https://www.yoctoproject.org/">Yocto</a>, can use this site. It
+provides stable URLs of all the released tarballs that can be put in
+build scripts and package recipes.</p>

 <p>Not yet. For now the links to the live555 tarballs are direct links
