Just got this update the other day and am confused somewhat, as to the architecture of the update numbers? I thought the first four were the year of version 9, followed by the week and day with other minor modifications following. Obviously, we are in 2019, so why would the update not show 2019? I show the first car to receive this update received it on 1/22/2019..........so why would the update not show the nomenclature of 2019.4.3 being year 2019, 4th week of the year, 3rd day?
