Anyone Know What Improvement are in 2018.12.1 b39b759 ?
- Thread starter barjohn

With the level of release notes recently, we may never know. It may be the usual ‘performance increases and bug fixes’ 
I suspect with the slow rate that 2018.12 was rolling out, it may be a fine tuning. But hard to say. 10.4 should have been ‘nothing much’ and was a whole new AP.
The other problem is you can’t even tell now if it’s 3 only or for everyone. 12 was for all three lines. I guess we assume that’s the norm now?
As of right now still only that one car on ev-fw.com or TeslaFi.

Just installed this release on our Model 3. I think release notes are same as for 2018.12 - steering wheel button updates (right scroll button adjusts TACC cruising speed and follow distance, left button adjusts steering wheel and both outside mirrors), automatic emergency braking speed increase from 50 mph to 90 mph, phone key unlocks when you pull the door handles, trunk when you push trunk switch (instead of just proximity), rearranged touchscreen icons.
So probably minor bug fix.
Or a new AP .

Sounds like 2018.12 for Model 3s. I wonder when we will get to generic all model updates again?
ED. TeslaFi shows 4 3s with 2018.12, so maybe not.

Do we have a list of Elon-promises and expected updates to any or all three Model line operating systems? Maybe it’s somewhere else on the forum but I haven’t made an extensive search.
Right, 2018.12 appears to be the first release on all car lines. Now to see if any of the rest of us get 12.1!

Wonder if the people who put that they got 2018.12 on their Model 3 actually had 2018.12.1 and only saw the S/X version on the site and assumed that was the one they should register. This is the first update round I am going to experience as my 10.5 arrived on the drive home on 3/25. Sure, this could be the first unified release, but from the history of updates so far there has always been a separate release for the Model 3's.

With Tesla-Fi, it automatically enters the information for you and so does the Tesla firmware tracker after your initial entry. The latter assumes you set up an account. Anyway, only two showing and one person in a thread said he got this update at the SC today.
Ev-fw.com can do manual entry if you want and we have see screwups recently but there are at least three Model 3s with 2018.12. One looks like it loaded it twice (same VIN prefix and mileage).
So yeah no idea what’s up here. Was this an experiment in consolidated software and now back to a separate version for the 3?

I'm not liking the call out to Traffic Aware cruise control, I want speed up/down on plain vanilla cruise as well.
My car has 2018.10.5 and I have the heated seats and key management etc mentioned, but no right-scroll-wheel changes.

I got 2018.12.1 yesterday. Every once in a while my TACC becomes available. So far, my auto steering has not been available. I have been having issues previously. I suspect there is a problem with my Autopilot firmware.

Pretty sure 12.1 is just the Model 3 version of 2018.12, but yeah, my 10.5 (the Model 3 version of 10.4) has the rear seat heat, phone key update, icons update, manual on setting screen... I guess they have all the old changes listed because people don't read what's new with EVERY release. When is the last time you read the release notes on the apps you downloaded onto your phone?

As was said, several 3’s have the same version of 2018.12 as the S and X. Verified by TeslaFi.
We all read all the release notes. And yes they do repeat the notes but normally there is no real content and none for AP. Phone apps often have ‘Increasing performance and bug fixes.’

Right, the previous notes are useful. But when they repeat the ‘current’ ones is when things can get confusing.
12.1 is a bug fix. I was one of those first 3 Model 3s with 3018.12 and my install failed twice causing me to have to take it to the service center. 12.1 was the fix that corrected the installation problem. The first time it failed, it disabled autopilot. The second time, autopilot worked but the log still showed that the installation failed. While charging afterwards, I was getting a Radick charging for your messages on the app and when I went back to my car, the stereo was blasting at 100% while it was charging. Weird and I hope that that is all now resolvedAll those changes (scroll wheel functions) were in 12. As usual, we don’t know what’s in 12.1.
Also, for what it is worth, the loaner P90D Model S that I’m driving right now just updated this morning to 2018.12 too. It is a 2016 with AP1 hardware.
As a follow up, I am driving on a freeway right now and have confirmed that the Autopilot nag time has been reduced to every 1 minute now:-( Not a big deal, but in comparison to every 2 mins in the Model S with AP1, I would prefer the extra time. I would imagine this is the result of changes to the Autopilot code?
