It's a dead/abandoned project imho. I have one, and I can't use it anymore as the iOS app it's totally bugged. I can't edit Variax params as it crash, and the app it's just very unstable, crashing randomly.
I contacted L6 support, they said they know it's bugged, but they don't know when there'll be an upgrade.
As for the firmware, again, I think there'll be no changes as it's a pretty much abandoned device. If isn't Helix, everything else doesn't last that much at L6 these days.
Said that, I wish they stop doing devices with editing OS dependent, since that's creating an obsolete device as soon as the OS changes and makes the editing app obsolete and/or not running anymore. I'm sick of that honestly.
