    Has anyone with a new MCU (Model S/X) received firmware 2018.12 yet? Wondering if this is another release in the 2018.10.4 "branch" that won't be coming to the newest cars, as I'm not seeing it yet on my MS 75D with new MCU.

    I wouldn't worry about not seeing it yet. Judging by the stats, only 5-10% of vehicles are reporting 2018.12 so far. That said it looks like it's hitting all known vehicles, including pre-AP, HW1, and HW2. So chances are good that you'll get it. But releases usually stagger out over a period of days or even weeks.

    Not sure 2018.12 is for MCU2. Every other release (lol, two of them?) we had different numbers. So there may be a 12.1? for MCU2.

    Just saying that 2018.12 could be only for S/X MCU1.

    So I picked up my X75D, have the MCU2, but apparently got the 2018.12. For most part, its working but connectivity is a big issue. I've got LTE signal 5 bars but no connectivity and cannot connect to wifi either. Frustrating part is I'm unable to reboot by any technique (2 finger scroll, 4 finger scroll & top buttons, power off in settings or brake and all above)
    Tesla states they are working on a bug, is there a way to go back to a previous version ? It seems 2018.10.4 is working fine on MCU2

    I have 2018.12 + New Navigation on my MS100D March Build with New MCU.

    If MCU1 and MCU2 are both running 2018.12, could someone with MCU1 check what browser they are running? Because up until now at least they have been running on different browser versions.... if they are now on the same browser people with MCU1 might be seing better speeds???

    According to Tesla Firmware Upgrade Tracker you will need 2018.14 to get the "MCU1-New Browser". Interesting today I just downloaded 2018.12, which does not include the new browser but does include support for the App update that allows control of trunk and frunk open / close, like available on Model 3.

    I asked for the firmware to be pushed today, and 2018.12 came out.
    Was hoping for 2018.14.
    I've got MCU1.
    Dang.
