I just upgraded to 1.21.2.1 and noticed a "feature change" that defies logic. I have a 2016 SGS, and can no longer view the air temp, oil pressue, etc. when the power is "off" on the radio.
Before the upgrade I could hit the info button on the right handgrip and get the display with the radio on or off.
I'm a software guy, been writing user interfaces since 1985. I cannot imagine what the software designer was thinking when he or she decided to change the software to remove this capability. Beyond dumb, and I sure hope that everyone complains enough to get the feature restored in the next update.
