Exactly correct - no way I'm changing software right before a 1000-mile (each way) trip.
I think Dynon did this release now, just before OSH, for the exact same reason the FAA started issuing LODA's when requested - so that both of them could stand up and say "We've already fixed that - see, look here..." when questions start flying at the KOSH meetings.
I updated to 16.0.4 yesterday after saying a Rosery! I have two 10" classics. It's all working fine. I had missed the update before and didn't realize this one was just released!
