Just received this on my Model 3 (up from 2018.18.2). Release notes are identical to 18.2. Hope this fixes my no-sleep vampire drain. Edit: Nice, looks like I *am* the bleeding edge, first car on TeslaFi to report this firmware. Wish me luck. Edit 2: One day in the vampire drain still going at 1 mi / hr. Car never goes to sleep. Edit 3: After disabling TeslaFi data logging vampire drain seems to not happen anymore. Edit 4: I now have TeslaFi logging on, with Sleep controls enabled and car sleeps with less than 1 mi / night loss. See post #77 for more detail.
