18.12 Release Notes:

Model 3:
Steering wheel button updates
For your convenience, we've updated the functions of the scroll buttons on the steering wheel.
The right scroll button now lets you quickly adjust Traffic-Aware Cruise Control settings. To increase or decrease the set cruising speed, roll the right button up or down. To adjust the follow distance between you and the vehicle ahead, press the right button to the left or right. You can still adjust these settings from the touchscreen and press down on the button to activate voice commands.

The left scroll button now lets you adjust your Model 3 side mirrors and steering wheel. Start by tapping the Controls icon on the bottom left corner of the touchscreen and then tap Quick Controls > Adjustments

To adjust the mirrors, tap Mirrors and select the LEFT or RIGHT mirror icon. Then, scroll the left button up or down, or press it left or right.

To adjust the steering wheel, tap Steering Wheel and scroll the left button up or down, or press it left or right.


Model S/X: North America Only
Introducing new Navigation (Beta)

Whether you’re on your daily commute or heading out to a new destination, you can rely on Navigation to give you the fastest route and provide more accurate estimated arrival times. It will route you around traffic jams and guide you through complex maneuvers when required.

If traffic conditions change and there’s an alternate route that will save time, Navigation will automatically reroute you. As with the previous system, you can control how aggressively Navigation does this: just indicate how much time an alternate route should save by adjusting the setting in CONTROLS > Settings > Apps > Maps > Navigation > RE-ROUTE IF IT SAVES MORE THAN

Navigation prevents you from missing turns by giving you a clearer view of upcoming maneuvers. More responsive guidance prepares you for complicated intersections or multi-lane interchanges. Each turn and highway exit that you should take is clearly labeled in blue, whereas cross-streets or highway exits that you will pass are labeled in black, to help you monitor your progress along the way. In addition, guidance and labels match real-world road and highway signs wherever possible.

As you get closer to a maneuver, the instrument panel view will zoom in to provide greater clarity and, if necessary, will highlight the lane (or lanes) that you should be using. This makes it easier to see how close you are to the turn, the cross streets that you’ll pass, and which direction to take.

We welcome feedback about the new Navigation Send email to [email protected], or press the voice commands button on the right side of the steering wheel and say "Note," followed by your comments.

That should make some Model 3 people very happy - the awkward methods of adjusting AP settings were one of the bigger complaints I've seen.
 
Drove this AM with 2018.12, I did not notice any difference with Navigation.
It's possible they can just flip a switch/bit on Sunday and enable it for everyone who has downloaded 2018.12. Both versions could exist in the code and they would just enable one and disable the other. If there are any issues, they could instantly flip you back to the previous version while fixing things. Then in a future version, they can remove the old navigation.

We already saw the new maps were available last August and it's a simple change to enable them or disable them and revert to the current non-vector maps.

I got the update yesterday, maps are the same but the engine is definitely improved. Much snappier zoom, the load time for a route is about half the time. Tiles refresh much quicker too. I still have 3G and it is a noticeable upgrade.

I don't remember ever seeing lane recommendations, like Google Maps, but they are there now. As stated in previous posts, this probably updated the backend and Tesla will monitor bugs. If and when they feel comfortable they will push map and more features out.

It would be a disaster to push an entirely new UI and to have it fail due to bugs.
 
Moderator note: Merged two 2018.12 threads together.

Not targeting anyone in particular with this next comment: These firmware threads tend to get a little chatty with messages of the form "I got something, I'll you know what it is when I install it". These don't really add much value to the discussion (partially because at that point in the update cycle there's no way of knowing what version is to be installed!). Once you've actually applied the update in your car, that would be a good time to share anything useful you've found (e.g. release notes).

Thanks,

Bruce.
Thanks for the heads up but I for one appreciate the "chattiness" whenever a new release appears.
I get info from what the other users have experienced and I have uncovered a few tidbits of palm slapping.
Saves on my forehead :)
 
Okay, so 2014 P85D with AP1... UI, definitely more responsive. It's not as fast as the new MCU in the 3 but it's definitely no longer an issue for me. (It used to be an issue for me because it was too laggy--now it's good.)

AP... It's hard to tell if it is better. My drive on surface streets, highway and freeway into work today felt better, more smooth, it seems to better handle lane changes with a lot of traffic. It felt smoother overall and quicker at identifying lane markings. It also took a hill with a turn like champ today, though it's done that before but rarely. Maybe it will keep doing it.

Chattiness about a given firmware revision is fine. I think that's what you mean.

My (main) point was that if (say) I've just got a notification on my phone for a new software update, I probably shouldn't post anything about it before I've actually installed it.

The update took 25mins on my car. (From when I started the installation on the screen until I recived the "update finished" notification on my phone). So doesn't seem to be any extraordinary update size wise.

It may install faster outside North America because it's not updating the navigation system.

Those release notes strongly make it sound like this version consolidates all cars, including Model 3 and possibly MCU2 as well. That could explain the larger filesize.

I doubt they can have one unified update at this point. The new and old MCUs for the S/X are different processors which have different instruction sets. The code has to be compiled differently for the two processors and it would make the download twice as large to have one download for all. Half the download would be discarded on every install.

I believe the core MCU is the same on the Model 3 and the new S/X MCU, so there is a possibility for a lot of overlap there, though the two systems have very different peripherals.
