 - Support objectOverrides using `.spec.objectOverrides`.
   See [objectOverrides concepts page](https://docs.stackable.tech/home/nightly/concepts/overrides/#object-overrides) for details ([#831]).
+- Enable the [restart-controller](https://docs.stackable.tech/home/nightly/commons-operator/restarter/), so that the Pods are automatically restarted on config changes ([#833]).
 
 ### Changed
 
 - Pin k8s-openapi to `0.26.0` ([#831]).
