How Tesla releases software updates and when you will get an update

By Nuno Cristovao

You may wonder how Tesla releases updates and why there are so many versions. We covered what Tesla software version numbers mean and here we'll talk about Tesla's workflow when developing new features and how they decide what goes into each software update.

Tesla workflow for new features

Master and Develop

There isn't a single codebase. There are two main branches of code and new features and releases are based off of these two branches. The 'master' branch holds Tesla's production code while 'develop' has all of Tesla's latest approved code.

Feature Development

When an engineer or team creates a new feature, they'll start a new branch with the latest develop code. All of their work is isolated in this branch until work is complete.

There are many features being developed concurrently. They'll usually be completely independent and have no knowledge of other features that are currently in development. Once development is completed for a specific feature, it will then be tested and merged into the main develop branch. Other features in active development now become aware of this new feature and it will be merged into their code as well.

New Update

When Tesla is ready to release a new update, they will usually grab the latest code from the develop branch and build a release. QA will test this release code and if any issues are found, fixes will be made directly to this release.

Once the code is deemed ready for production, it will be merged into master and rolled out to a small percentage of the Tesla fleet.

Tesla Introduces Most Affordable Car: Long Range RWD Model 3 with 363-Mile Range for $34,990

Tesla has brought back the Model 3 Long Range Rear-Wheel Drive variant, which starts at $42,490. However, due to the batteries in the Long Range model, it qualifies for the $7,500 federal EV rebate. This makes this new model the cheapest model in Tesla’s lineup after the federal rebate that comes off at the point of sale.

After the federal rebate, this model is $34,990, exactly $4,000 less than the standard RWD model with the smaller LFP battery.

Improved Range

The Long Range RWD variant boasts a range of 363mi (vs 341mi for the AWD, and 272mi for the regular RWD), and a 0-60mph of 4.9sec (vs 4.2sec for the AWD). This makes the new Long Range RWD Model 3 Tesla’s longest-range economic vehicle (Model 3 / Model Y). The Model S AWD boasts an impressive 402-mile EPA estimate.

Other than the lack of a front motor for handling in rough or slippery terrain, or having a faster 0-60, the Long Range RWD is a fantastic option for most people.

It’s worth noting that only the Long Range AWD model can unlock Tesla’s Acceleration Boost, which increases power and reduces the vehicle’s 0-60 times by about half a second.

Tesla FSD V12.5 to Combine City and Highway Stacks, Introduce Vehicle-to-Fleet Communication and More

By Karan Singh

As FSD V12.4.3 continues to get released to more vehicles, Elon Musk has posted that FSD V12.5 is already in testing and will include several key features.

The improvements in v12.5 are supposed to focus on rarer, more complex situations and vehicle-to-fleet communication. Tesla’s Autopilot lead, Ashok Elluswamy, also mentioned that FSD would gain the ability to go in reverse around this time.

Merge City & Highway Stacks

FSD v12 has been a multi-stack setup so far, with a city-streets stack that is end-to-end, and an older highway stack that was carried over from v11. FSD v12.5 will once again merge the city/highway stacks according to Musk, who confirmed the feature yesterday. That means that there will no longer be an implicit highway stack.

This could cause some regressions during highway driving, similar to the ones we experienced when Tesla first merged highway and city stacks back in FSD v11. Ultimately, when the issues were ironed out, we ended up with a smoother and better Autopilot experience on the highway. When FSD v12.5 rolls around, we may see some similar issues but expect FSD v12.5 to do to highways what v12 did for city driving.

Vehicle-to-Fleet Communications

Tesla’s FSD relies heavily upon maps, with the mapping information designating routing and lane changes. When vehicles encounter difficulties, they are unable to communicate that back to the rest of the fleet. This results in every vehicle encountering the same problem. With FSD V12.5, vehicles will be able to communicate road closures or other obstacles back to the rest of the fleet in real-time. This will turn FSD into software that’s constantly improving as the fleet gathers more data, instead of having to wait for a software update.

Cybertruck Finally Gets FSD

In a recent post on X, Musk also confirmed that V12.5 will finally bring FSD to the Cybertruck. Currently, all Cybertrucks only have access to Traffic Aware Cruise Control (TACC). Autopilot and FSD capabilities should arrive alongside all the other features.

Actually Smart Summon

Musk has talked quite a bit about Actually Smart Summon. With FSD 12.5, the new vision-based summon may finally be released. This will introduce Smart Summon capabilities to vision-only cars for the first time. However, it’s expected to be a drastic improvement for all vehicles in similar ways to the new Autopark. The new summon has been tied to the ability to move the vehicle in reverse by Tesla’s Autopilot lead, so expect either both of them to arrive in FSD 12.5, or be held off for a later release.

Release Date

Musk originally mentioned that FSD V12.5 would be released in late June, however, there were several delays with FSD 12.4 and that time frame has now come and gone. FSD 12.4 was initially released in May 2024, but it went through several lengthy revisions before it was introduced to public testers. Going by that time frame, it appears that FSD 12.5 was expected to be released about 4-6 weeks after FSD 12.4. If FSD 12.4.3 is finally got a good spot, we could see FSD 12.5 become available in the next 4-6 weeks or about late August.
