    <#docker-images-updated>Docker Images Updated

The Docker images
<https://github.com/opennms-forge/docker-horizon-core-web/> have
recently been updated to have a couple of new features:

  * Craig recently extended the Docker image to have support for Newts
    in Cassandra
    <https://github.com/opennms-forge/docker-horizon-core-web/blob/master/README.md#running-on-cassandra-with-newts>.
    There is also an example stack with just one Cassandra node to try
    it out.
  * Before starting or updating, the configuration files are now always
    checked with the config-tester.

Environment variables and more details can be found in the README
<https://github.com/opennms-forge/docker-horizon-core-web/blob/master/README.md#running-on-cassandra-with-newts>.
The changes are applied to images with tags |bleeding|, |drift| and
|21.0.4-1| (and higher).
