The notification reads: > Please note: Your current RLN image version is no longer supported. Update your node to the latest version. ### Steps 1. **Click the Upgrade button** — Navigate to the node page where the notification block appears and click **Update** to trigger the upgrade process. This initiates an upgrade to the latest RLN image. 2. **Wait for the upgrade to complete** — The process may take a few minutes. During this time, the node will be **locked** and unavailable. 3. **Unlock the node** — Once the upgrade is complete, the node remains locked. To resume using it: * Navigate to the Node Page for that node. * Click the **Unlock** button. * The node will be fully operational on the updated image. ## Automatic Bulk Upgrade (Scale or Wallet Plan) For users on the Scale or Wallet Plan, the system provides automatic bulk upgrades. ### How It Works When a new RLN image version is released, all user nodes are **automatically upgraded** to the latest version. Manual triggering is not required. ### Post-Upgrade: Unlock Nodes After an automatic bulk upgrade, all upgraded nodes are locked. To continue using each node: 1. Navigate to the Node Page for the respective node. 2. Click the **Unlock** button. Automatic upgrades ensure all nodes stay up-to-date without user intervention. However, **manual unlocking is required for each upgraded node** to resume functionality. ## Upgrade via API You can also check node version status and trigger upgrades programmatically using the Cloud API. Refer to the [RGB Lightning Node API](/cloud/rgb-lightning-node-api) reference for the relevant endpoints.
