New update on Teslafi: 2019.32.12.3

This site may earn commission on affiliate links.
12.3 looked to be aimed at MCU1 cars (No-AP,AP1, AP2.0 and very small set of AP2.5)
12.4 looked to be aimed at MCU2 cars (AP2.5 and AP3.)
12.8 seems to be MCU1 cars again.

I don't think the upgrade path is 12.3 -> 12.4 -12.8. I think its split
MCU1 12.2 -> 12.3 -> 12.8
MCU2 12.2 ->12.4 -> ???

I thought someone had mentioned in another post that 12.4 was to patch a sensor beeping problem after HW3 retrofit
 
This morning I received 2019.32.12.7 I looked back on what I had installed and count that I've had 9 different versions of 2019.32 installed and 4 different versions of 2019.32.12 installed so far. I guess the "advanced" option is doing something here after all, though we still don't have 2019.36.x in Australia.
