On Github, it looks like all the firmware releases after 2.1.2 are marked as pre-release. Is there a specific reason? Should I be wary of updating to the 3.x.x versions for production usage?
Yes, our update mechanism in the app autoupdates firmware to the latest release. Marking as pre-release doesn’t trigger the autoupdate in the app. We will be removing the pre-release from 3.X release soon.
