The latest build of Tesla’s Full Self-Driving (FSD) Beta software is on its way to reaching customer cars, currently being tested by employees. This version of FSD Beta is v11.4.6 which has a build number of 2023.7.26.
We now have release notes for the build thanks to Dan, who received the software update on his vehicle in the past 24hrs, before most of the software tracking websites like TeslaFi and TeslaScope even listed the release.
Interestingly the previous public release was v11.4.4 and if you’re wondering what happened to the v11.4.5 release, it made it as far as employee cars, but was not released to the public. It appears Tesla saw a bug or issue that prevented them from rolling that build to customers, showing how important that step is in the process.
Below is a history of the FSD Beta releases, which unfortunately is still not yet available in Australia, although with the recent hires of ADAS testers, may not be too far away.
- October 2020: Tesla began rolling out FSD Beta to a small group of early access testers.
- April 2022: Musk said that there were 100,000 FSD Beta testers.
- September 2022: Tesla said in its Q3 2022 shareholder deck that there were approximately 160,000 FSD Beta testers in North America.
- September 2022: Musk announced that Tesla would be expanding the FSD Beta program to an additional 60,000 owners in the United States and Canada.
- December 2022: Musk said that there were now 285,000 FSD Beta testers in North America.
- January 2023: Musk said that Tesla would be expanding the FSD Beta program to all North American owners who purchased the option.
- March 2023: Musk said that there were now 400,000 FSD Beta testers in the United States and Canada.
This week Tesla held their Q2 2023 earnings call and released the latest shareholder slide deck. While they don’t provide an updated figure on the number of vehicles with FSD Beta, page 8 shows the cumulative total for miles driven on FSD Beta has reached 325 Million miles. With more Tesla vehicles on the road and the software becoming more useful, the number of FSD Beta miles is likely to accelerate rapidly.
FSD Beta v11.4.6 Release Notes
The release notes for this version are the same as FSD Beta 11.4.5, which was never released to the public, and FSD Beta 11.4.4, with the exception of the last bullet point.
- Improved short-deadline lane changes, to avoid going off-route, through better modeling of target lane vehicles to improve gap selection assertiveness.
- Improved offset consistency when controlling for static obstacles. Also improved smoothness when changing offset direction by adjusting speed more comfortably.
- Improved handling of oncoming cars on narrow unmarked roads by improving prediction of oncoming car’s trajectory and leaving enough room for them to pass before re-centering.
- Improved Occupancy Flow prediction from the Occupancy Network for arbitrary moving obstacles by 8%.
- Expanded usage of the new object ground truth autolabeler for the NonVRU detection model, improving distant vehicle recall and geometry precision for semi-trucks, trailers, and exotic vehicles.
- Improved VRU control by expanding planning scope to control gently for low-confidence detections that may interfere with ego’s path.
- Improved handling for VRUs near crosswalks by predicting their future intent more accurately. This was done by leveraging more kinematic data to improve association between crosswalks and VRUs.
- Improved ego’s behavior near VRUs by tuning their assumed kinematic properties and utilizing available semantic information to classify more accurately their probability of intersecting ego’s path.
- Improved Automatic Emergency Braking recall in response to cut-in vehicles and vehicles behind ego while reversing.
- Introduced Automatic Emergency Braking on general obstacles detected by Occupancy Network.
- In this update Tesla is introducing Automatic Emergency Braking for objects detected by their Occupancy Network.
