## Breaking Changes
- **`ephemeralStorage` renamed to `diskSize`**: The `nodeGroups[name].ephemeralStorage` field has been renamed to `nodeGroups[name].diskSize` to better reflect its purpose (persistent disk for kubelet and containerd data). There is no backward-compatibility fallback; users MUST update their configurations to use `diskSize` instead of `ephemeralStorage`. Existing VMs will be automatically rolling-updated via CAPI when the new values are applied.
