Hi, @Farbrook, to update your GX, get into Remote Console and there go to Settings → General → Firmware.
Latest official version at the moment is v3.63.
For details of recent features, see public - Venus OS v3.60 Release - Google Slides.
Try the new UI, also remotely.
In case you have installed modifications (downloaded some add-on from a website somewhere (not Victron) and installed that using a USB stick), then make sure to update or remove those first. See: White page in Classic UI after update from v3.55 to v3.60 or later version? - #3 by DutchSolarFreak.
But most people don’t have add-ons aka modifications.
