Couple of small changes I haven't seen reported:
--When TACC is turned on for the first time since the car was started, the following distance index (1..7) displays momentarily. Previously if I wanted to know the index I had to momentarily change it to get it to display.
--After I exit the car in my garage and plug in the UMC for charging, with 7.1 it showed the scheduled charge start time on the instrument panel. Now, electrical metrics placeholders and the new see-through cartoon car with the big battery show, with no indication of charging start time.
