This is a minor firmware update. Updating across minor revisions (e.g., from 2.2.1(0) to this version) will preserve all existing settings and programs. Updating across major revisions (e.g., from 2.1.9 or 2.2.0 to this version) will trigger a factory reset, including WiFi settings. Before updating, please export a copy of your current configurations to ensure you can restore them in case a factory reset is triggered.
