Just finished installing what I think is the latest software update, 7.1 (2.14.66), and doing a line by line comparison of its release notes to that of the previous version I'd installed, 7.1 (2.13.120). No changes as far as I can tell. Also put about 30 km on the car since the update and did not notice any changes. BTW, checking the Tesla Firmware Upgrade Tracker (Tesla Firmware Upgrade Tracker Web App) it looks like a lot of people are receiving an update today. Anyone notice any changes in the way their S's drive with the new update?
