My Pebble Steel is still on firmware v2.9. Is firmware update supported? Or is the Android way currently the only way?

QML is great tho, it's the nicest way of doing GUI-stuff I know. Not that I know much. But still, it was the first time I actually enjoyed making a GUI. I'm not much help here tho, as I'm procrastinating my own little QML project for over a year now
