NS Panel Pro Firmware 3.9

Hi all
I just received my Sonoff NS Panel Pro 120 and want to sideload apps to the device (FullyKiosk). The device is currently on firmware 3.7 and I receive an update notification for firmware 3.9. Should I update to 3.9 before entering dev-mode / ADB to sideload the apps or should I better stay on 3.7?

The Sonoff release notes lists 3.8.0 as the latest version (21st Feb 2025). Version 3.9 is not listed yet.

Thanks
