 Starting from version 0.39.0, the chart implements enhanced security by default:
 
-- **Removed Permissions**: The default ClusterRole has been changed from `cluster-admin` to `''`.
+- **Removed Permissions**: The default ClusterRoleBinding creation has been disabled (`create: false`), removing the previous `cluster-admin` binding.
 
 **Automatic Migration**: When `clusterRoleBinding.create` is enabled, a pre-upgrade hook removes the old `headlamp-admin` ClusterRoleBinding during upgrades to help migrate to the new security configuration. If you have disabled this option or manage ClusterRoleBindings manually, you must remove any existing `headlamp-admin` ClusterRoleBinding yourself.
