+The release notes for **Cumulocity IoT Edge release 10.18.0** contain important information about all the changes, including new features, enhancements, and fixes, that have been made to both **Cumulocity IoT Edge Appliance VM** and **Cumulocity IoT Edge on Kubernetes**. 
+
+
+You can find the corresponding documentation for **Cumulocity IoT Edge Appliance VM** at https://cumulocity.com/docs/edge/edge-introduction/ and for **Cumulocity IoT Edge on Kubernetes** at https://cumulocity.com/docs/edge-kubernetes/k8-edge-introduction/.
+
+
+### Cumulocity IoT Edge Appliance VM
+There have not been any significant improvements or fixes related to this component since the last Maintenance release.
+
+### Cumulocity IoT Edge on Kubernetes
+Cumulocity IoT Edge on Kubernetes has reached General Availability (GA) and is now ready for deployment in production environments.
+
+#### Offline installation
+
+Edge installation on Kubernetes now offers support for installation in an offline or air-gapped environment. This ensures that the required software, Helm charts and Docker images, are available in the disconnected environment through an [Open Container Initiative](https://opencontainers.org/) (OCI) compliant private registry.

+For more information, refer to [Installing the Edge operator (offline)](https://cumulocity.com/docs/edge-kubernetes/installing-edge-on-k8/#install-operator-offline).
+
+#### Metrics monitoring port
+
+The Edge operator's Prometheus-compatible metrics port has been changed from 8443 to 3443 due to a conflict with another core component.
