 ## [Unreleased]
 
+### Added
+
+- The operator can now run on Kubernetes clusters using a non-default cluster domain. It should automatically detect the
+  correct domain to use, but you can also use the env var `KUBERNETES_CLUSTER_DOMAIN` to set the domain explicitly
+  or use the helm-chart property `kubernetesClusterDomain` ([#290]).
+
 ### Changed
 
 - BREAKING: Bump `stackable-operator` to 0.78.0 which includes a new `AuthenticationClassProvider` member for Kerberos. This will need to be considered when validating authentication providers ([#285]).
