 ## [1.11.0] - 2026-06-30
 
 ### Added
-- `node.zone` Helm value for the node DaemonSet. **Required** with `--mode=node` to pass `--zone` to the CSI plugin
+- `clusterZone` value for both controller and node. Setting it avoids an API call on the controller startup, since it's needed for the DaemonSet already.
 
 ### Changed
-- Node DaemonSet runs `--mode=node` instead of `--mode=monolith`. UpCloud API credentials are no longer deployed to every cluster node, reducing credential blast radius
+- Node DaemonSet runs `--mode=node` now instead of `--mode=monolith`. UpCloud API credentials are no longer deployed to every cluster node, reducing credential blast radius
+- Controller StatefulSet and Node DaemonSet use `clusterZone` for the `--zone` flag
