I got 2019.8.3 da116a6 on my 2016 pre-facelift 90D. I see the climate control GUI layout changed, and 'dog mode' was added. The bad news is that the web browser is now virtually unusable, as it much much slower. I use the browser mainly for the Chargepoint destination charger app. When I enter my username credentials, it took over 10 minutes for the screen to echo the input from the onscreen keyboard. I rebooted the computers but it did not change he behavior. What a shame. If I had a dog maybe it would be worth it. However, if you do have a dog and leave it in the car, be sure to put a notice in the windshield that the dog is okay, or you might lose a window if an over zealous animal lover calls the cops.
