+At the time of <a href="http://localhost:8000/news.html#apache-solrtm-900-available">Solr 9 release</a> on May 12th
+it would pull Ubuntu 20.04 (Focal Fossa), but at the end of May, it was <a href="https://github.com/docker-library/official-images/commit/6d689db4846a3eb4c2ebd0e5d06139c650ef3bbb">auto upgraded</a> to the brand new Ubuntu
+22.04 (Jammy Jellyfish). This was not our desire, and we have learnt that due to this, our image is no longer compatible
+with Docker client versions before 20.10.16. Having a "floating" linux release like this can also break the image in 
+other subtle ways, as well as breaking downstream images using us as a base image.</p>
+<p>We therefore decided to start pinning not only Java release, but also Linux release in our official Docker images.
+This means that Solr 9.0 is once again based on Ubuntu 20.04 Focal, i.e. a downgrade.</p>
+<p>Note that our images will still receive important Linux bug fixes from time to time, but you won't get them unless you
+re-pull the image. When we upgrade to Ubuntu 22.04 in the future, it will be a deliberate decision and not by accident.</p>
