Version 2018.50.5 c9323af, same as everyone else I believe. Nothing extra in the release notes. I'm not making any grand claims, just reporting interesting observations. As a software RnD director, I can tell you we don't put everything in the release notes.
Also, that whole conversation about degradation and car-to-car deviation is a bit oblique, the car only has 1052 miles right now. Most MR are probably similar. We're on the efficient frontier, man. Besides this is not a comparison of cars, but a comparison of before and after of one car.
