   assembles all relevant Kubernetes resources before anything is applied ([#841]).
 - The RBAC ServiceAccount and RoleBinding are now built with the operator-rs `v2::rbac`
   functions and carry the full set of recommended labels ([#846]).

+- Bump stackable-operator to 0.116.0 ([#855], [#865]).
 - The reconciler now applies resources and derives the cluster status in discrete
   apply and update_status steps ([#856]).
 - All product containers now run with `securityContext.runAsNonRoot` set to `true` to improve security ([#860]).
+- `envOverrides` names are now validated by the shared `EnvVarName` type rather than by
+  operator-specific validation code ([#865]).
+- Environment variable overrides (`envOverrides`) are now applied after all environment
+  variables set by the operator. In particular, `CONTAINERDEBUG_LOG_DIRECTORY` and the
+  authentication-related environment variables can now be overridden, whereas previously the
+  operator's values always took precedence ([#865]).
+- BREAKING: Remove the `app.kubernetes.io/component` and `app.kubernetes.io/role-group` labels
+  from the resources they don't apply to (previously set to `none` or a placeholder value).
+  StatefulSets created by older operator versions cannot be updated in place: after the
+  operator upgrade, delete each broker, coordinator and router StatefulSet so that the operator
+  immediately recreates it with the new labels ([#865]).
