Ford just released 3 new System versions. Two MY19 3.3 labelled 3.3.19016 and 3.3.19052 and a new MY20 3.4 version labelled 3.4.19050.
F8 maps for MY18.5+ APIM are now available too, as Ford started install them in their factory on some new cars.
There is a bad news too... the /etc/shadow file, containing the root password has been removed, at least on the latest 3.4 build. So it's no longer possible to login on the system wthout additional modifications.
