Love the new and long-due features, but am totally disgusted by losing all my years of configuration changes (smart home, profiles, calendars, etc.). Just want to chuck the thing in the trash at this point.
I highly suggest putting a huge warning at the beginning (not end) of any FW update notification email and FW update description if an update will overwrite a current configuration. Better yet, pop up a dialog box that warns the user and offers to make a backup of the configuration BEFORE any FW update.
