It's also worth noting that it's barely doing any 2018.18 -> 2018.18.2 replacements. Most of the people being offered this update are on .14.2 or before.
That doesn't make it feel like a wide release. I'm guessing all of this is working up to a 2018.20 or something with more substantial changes.
FWIW, at least on 2018.18, AP2, I've been pretty happy with radar braking so far. I've not noticed any phantom braking on common locations with phantom braking from last year when they first attempted to enable this feature.
At least you folks are getting updates. I’m still on 10.4 and have been for over two months. This is the longest I’ve gone between updates since I have been tracking my updates on EV-FW in 2015.
Based upon the EV-FW numbers, I suspect there are a substantial number of owners in the same condition.
