 - Add custom `hbase.rest.endpoint` property to the restserver `hbase-site.xml` ([#708], [#716]).
   - The custom `hbase.rest.hostname` and native `hbase.rest.port` properties cannot be used for
     discovery advertisement, as these should remain stable regardless of listener class used to expose the REST service.
+- Support objectOverrides using `.spec.objectOverrides`.
+  See [objectOverrides concepts page](https://docs.stackable.tech/home/nightly/concepts/overrides/#object-overrides) for details ([#725]).
