Moving from 3.3.xx to 3.4.0 is huge! For those of you who make sure your iPhone apps are up to date, note how many apps have to be updated when Apple updates at that level. Most app developers make changes to their apps to take advantage of the software improvements made in the iOS. In a (generally) closed app environment such as the Gravity, an update to the OS requires an update to the internal apps (HVAC, DDP, SSP - heck, even the app that moves the seats!)
This is a really big update and if this doesn't remove a huge percentage of the operational bugs, we're in real trouble. My vehicle is in service, so I can only rely on this forum for feedback, but I'm hopeful that this update changes everything they've found so far, so the next iterations can begin working on the features and not on the basics.
Cheers to Lucid Software engineering - I truly wish you well!
