We generally support Netplan versions that are being used by the latest Ubuntu LTS and newer. Please see Launchpad.net for the specific version numbers.

Netplan is a system component that is supposed to be driven as root. Its configuration might contain secret information such as WiFi passwords or VPN credentials, so it's recommended to keep the file permissions for Netplan's configuration very tight, as described in our threat model.
