Tesla's latest FSD Beta, version 11.4.6 is currently undergoing testing with Tesla employees. The software is not yet available to the public, but if testing goes well we may see a release in the near future.
However, it's also possible that this beta never leaves internal testing, much like FSD Beta 11.4.5, if major issues are discovered.
The latest FSD Beta available to consumers is beta 11.4.4, although many have expressed disappointment with this version and think it's a step backward. Many other owners are on FSD Beta 11.3.6.
Improvements to Automatic Emergency Braking
FSD Beta 11.4.6 shares the same release notes as its predecessors, 11.4.5 and 11.4.4, except for one notable addition. With this beta, Tesla has introduced "automatic emergency braking for general obstacles as detected by their occupancy network." This appears to indicate that automatic emergency braking will now activate for obstacles besides vehicles and pedestrians.
Tesla's occupancy network can identify objects, even if it can't recognize the entity, so Tesla may now have higher confidence in this object detection that it allows automatic emergency braking to activate in these circumstances.
Tesla recently made massive improvements to automatic emergency braking by allowing it to activate while the vehicle is traveling in reverse and for vehicles that are traveling perpendicularly to your car, such as if someone runs a red light at an intersection. Automatic emergency braking will now also activate at speeds over 120 mph, whereas before it maxed out at 90 mph.
Reducing Unnecessary Slowdowns
Although the only notable improvement in the release notes is to automatic emergency braking, Elon Musk chimed in on Twitter to reveal another improvement in this release. Musk says this beta will also "reduce unnecessary slowdowns." This is a common occurrence with FSD Beta in general, where it slows down for seemingly unknown reasons. Any improvements to this area will be welcomed.
As Tesla employees continue to test this latest version of FSD Beta, we may find out additional details of what other improvements may be under the hood. If testing goes smoothly it's possible we'll see a public release, although the timing can be anywhere from a few days to several weeks.
