Full Self-Driving (Beta) (part of 2023.12.10)
Autopilot Improvements
You can enable Full Self-Driving (Beta) by tapping 'Controls' > 'Autopilot' > 'Full Self-Driving (Beta)' and following the instructions.
Full Self-Driving is in early limited access Beta and must be used with additional caution. It may do the wrong thing at the worst time, so you must always keep your hands on the wheel and pay extra attention to the road. Do not become complacent. When Full Self-Driving is enabled your vehicle will make lane changes off highway, select forks to follow your navigation route, navigate around other vehicles and objects, and make left and right turns. Use Full Self-Driving in limited Beta only if you will pay constant attention to the road, and be prepared to act immediately, especially around blind corners, crossing intersections, and in narrow driving situations.
Your vehicle is running on Tesla Vision! Note that Tesla Vision also includes some temporary limitations, follow distance is limited to 2-7 and Autopilot top speed is 85 mph.

FSD Beta v11.3.6 (part of 2023.12.10)
Autopilot Improvements
- Enabled FSD Beta on highway. This unifies the vision and planning stack on and off-highway and replaces the legacy highway stack, which is over four years old. The legacy highway stack still relies on several single-camera and single-frame networks, and was setup to handle simple lane-specific maneuvers. FSD Beta's multi-camera video networks and next-gen planner, that allows for more complex agent interactions with less reliance on lanes, make way for adding more intelligent behaviors, smoother control and better decision making.
- Improved recall for close-by cut-in cases by 15%, particularly for large trucks and high-yaw rate scenarios, through an additional 30k auto-labeled clips mined from the fleet. Additionally, expanded and tuned dedicated speed control for cut-in objects.
- Improved the position of ego in wide lanes, by biasing in the direction of the upcoming turn to allow other cars to maneuver around ego.
- Improved handling during scenarios with high curvature or large trucks by offsetting in lane to maintain safe distances to other vehicles on the road and increase comfort.
- Improved behavior for path blockage lane changes in dense traffic. Ego will now maintain more headway in blocked lanes to hedge for possible gaps in dense traffic.
- Improved lane changes in dense traffic scenarios by allowing higher acceleration during the alignment phase. This results in more natural gap selection to overtake adjacent lane vehicles very close to ego.
- Made turns smoother by improving the detection consistency between lanes, lines and road edge predictions. This was accomplished by integrating the latest version of the lane-guidance module into the road edge and lines network.
- Improved accuracy for detecting other vehicles' moving semantics. Improved precision by 23% for cases where other vehicles transition to driving and reduced error by 12% for cases where Autopilot incorrectly detects its lead vehicle as parked. These were achieved by increasing video context in the network, adding more data of these scenarios, and increasing the loss penalty for control-relevant vehicles.
- Extended maximum trajectory optimization horizon, resulting in smoother control for high curvature roads and far away vehicles when driving at highway speeds.
- Improved driving behavior next to row of parked cars in narrow lanes, preferring to offset and staying within lane instead of unnecessarily lane changing away or slowing down.
- Improved back-to-back lane change maneuvers through better fusion between vision-based localization and coarse map lane counts.
- Added text blurbs in the user interface to communicate upcoming maneuvers that FSD Beta plans to make. Also improved the visualization of upcoming slowdowns along the vehicle’s path. Chevrons render at varying opacity and speed to indicate the slowdown intensity, and a solid line appears at locations where the car will come to a stop.
- Improved the recall and precision of object detection, notably reducing the position error of semi-trucks by 10%, increasing the recall and precision of crossing vehicles over 100m away by 3% and 7%, respectively, and increasing the recall of motorbikes by 5%. This was accomplished by implementing additional quality checks in our two million video clip autolabeled dataset.
- Reduced false offsetting around objects in wide lanes and near intersections by improving object kinematics modeling in low speed scenarios.
- Adjusted position of Automatic Blind Spot Camera when FSD Beta is active to prioritize the Autopilot visualization. Drag the camera to save custom positions.

Full Self-Driving (Beta) Suspension (part of 2023.12.10)
Autopilot Improvements
For maximum safety and accountability, use of Full Self-Driving (Beta) will be suspended if improper usage is detected. Improper usage is when you, or another driver of your vehicle, receive five ‘Forced Autopilot Disengagements’. A disengagement is when the Autopilot system disengages for the remainder of a trip after the driver receives several audio and visual warnings for inattentiveness. Driver-initiated disengagements do not count as improper usage and are expected from the driver. Keep your hands on the wheel and remain attentive at all times. Use of any hand-held devices while using Autopilot is not allowed.
The FSD Beta feature can only be removed per this suspension method and it will be unavailable for approximately two weeks.

Cabin Camera (part of 2023.12.10)
Analytics
The cabin camera above your rearview mirror can now determine driver inattentiveness and provide you with audible alerts, to remind you to keep your eyes on the road when Autopilot is engaged. Camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing. To change your data settings, tap Controls > Software > Data Sharing on your car's touchscreen.

Extras (part of 2023.12.1)
The release is one of the biggest user interface updates since the controversial v11 at the end of 2021 and where a number of changes were slowly reversed or reimplemented. In addition to the published release notes, a number of extra features have been spotted:
- The charging screen has been updated making it easier to move the battery level slider
- On a similar theme, the audio track slider has been updated and shows the track time when scrubbing.
- The small sub menu that pops up when certain features are activated, like wipers, can be controlled via the scroll wheel. This is an extension of the new dynamic nature of the scroll wheels and the ability to mute and end calls.
- The app draw (accessible by clicking the three dots) has been updated and provides more options and quick controls, although it otherwise looks very similar.
- The hidden service mode has had a few more tweaks including the ability to see the camera pitch details. In general, we advise against using the hidden service menu unless you are confident of the consequences.
- The Tesla app is also being updated. One undocumented feature is the ability to enter a destination and send it to the car. You've been able to send destinations to the car for many years, the only notable difference here is the car will show you potnetial charge stops if the route is long. We wouldnt really class is as a route planner like some have suggested given its very limited feature set.
- If you enter a text box such as enter detination in the car, and then use the voice controls, the car will insert the spoken text into the search box.
Reboot after an update
Lot's of people have random issues after a software install, many of them curing themselves after a reboot. As a general rule, we'd suggest always doing a scroll wheel reboot after a software update, simply press the two steering wheel scroll wheels until the screen turns off and then let go. The screen will come back within a minute or so, depending on hardware. It's certainly worth doing this is you notice any unusual behaviour, but prevention is better than cure. There's a second reset option which is to change the car configuration slightly, either the language, or wheel type. This also causes the car to do a soft reset and this has returned missing features such as Tidal. Our Guide to rebooting your Tesla provides more details.
How to get the latest Tesla Software Update?
In a word, you can't really force it yourself although you can help the car to download the update once it's been allocated to have an update. To do so, connect the car to WiFi, and maybe even consider a wireless hotspot when in use. Car's not connected to WiFi generally do not receive updates quickly.
If you visit the software screen and see the car hasn't checked for a few days, perform a scroll wheel reset. The car typically checks as soon as it reboots and we've had a software update immediately afterwards as a result.
You may find the car sticks at 50% for a while. We've seen reports that keeping the car awake will help speed past past this point as the car will try and sleep and halt the process. Even keeping the mobile phone app open may help to prevent the car sleeping.
Why do I not get some of the features or changes mentioned?
There are a number of reasons why a particular feature or change may not be included when your car upgrades. These include regional restrictions, hardware specific features, model specific updates and some changes are linked to software options purchased such as EAP or FSD. There are also times when software release notes are provided but only Tesla test engineers get the updates.
Not having a listed feature or update for a particular car is therefore quite normal. Some websites try to detail which cars get which features but this is often inaccurate, such as the blended braking update that came out with 2022.16 and the alternate routes option in 2022.28.
Against each release note we now list the car models and countries where a particular release note has been seen.
I thought I already had a listed feature?
Just as a feature may not land in every car, the feature may be mentioned in later releases when your car already has it. The release notes in the car are tuned to your car so, and while in general the car will only report a new feature once, that is not a rule that always holds true. Some websites say the feature is not available in your country whereas the reality is the feature has been there for some time
I'm on the FSD City Streets Beta
The FSD City Streets Beta is usually 2 to 3 releases behind the general software releases. This is normal.
Numbering convention
Release notes are numbered roughly using the a year.family.major.minor format. The year is self explanatory, the family release typically increments in 4's and is roughly the week of the year when the release family is launched, although these tend to slip over the course of the year. The major and minor release numbers of much debated, we personally believe these rarely contain new features not included in the family, and if there are differences it is linked to hardware specific versions.
When reviewing release notes, you may be interested in how a feature has evolved. To enable this we have also included a keyword search where you can search for a word or phrase and we will filter the results accordingly.
