What do Tesla software version numbers mean?

Everyone loves receiving new updates for their Tesla. But do you know what the version numbers mean and why there are so many versions? We take a look at exactly what Tesla version numbers imply and how Tesla creates and branches their code.

How Tesla numbers their versions

What It Means

A recent Tesla update had version number 2021.32.20 1b7f33580a5f. Let's take a look at how Tesla numbers their versions and what it means.

The first portion of the version number, 2021, is the year of the release. The second, 32, is the week number of the year. Since Tesla has a history of releasing a major update every four weeks, you'll almost always see this number in increments of four. After the week number is the revision of the build.

The first build of a release usually does not have a revision and it's simply known as 2021.32. This is the first build and is only rolled out to a very small portion of the Tesla fleet, if at all.

As Tesla gathers fleet data and learns about any issues, they'll make improvements and fixes to the release. The next update will have a revision number, such as '.1'. Revision numbers go by incrementally, although not always by one. The number is often arbitrary, but it should reflect the amount of changes in the release. For example, going from 2021.32.1 to 2021.32.2 would often indicate a smaller change than jumping to 2021.32.20.

The revision number should be looked at as a single number and not as a decimal. For example, version 2021.32.2 is an earlier build of 2021.32.20.

Hash

The seemingly random numbers and letters you'll see at the end of a version number is a unique key called a hash that is used to identify that code. A hash is used every time new code is added to a code base and the ones we see in an update are used to identify that specific release.

Gradual Updates

Tesla will often start with a release such as 2021.32 and they'll gradually roll it out to some vehicles, get data, make fixes and then roll out another release. By the time an update is in wide release, it likely has gone through various revisions and will have a higher revision number.

Tesla releases their updates gradually so that they can minimize any potential issues and keep everyone safe. If there are any major issues with a release, it likely only impacted a smaller portion of the fleet.

Tesla Insurance launches in Arizona and Ohio; now offered in five states

If you've had a Tesla for a few years then you probably remember what it was like getting an insurance quote for the vehicle.

Experiences vary, but it was not uncommon to come across insurers who would not insure a Tesla or who asked for an extremely high premium.

In fact, the problem was so big that Tesla decided to do something about it. They released their own car insurance division.

Tesla launched Tesla Insurance in 2019. Unfortunately, it was only offered in California at the time. Car insurance laws vary by state so Tesla needs to be approved in each state they want to do business in.

Tesla only expanded beyond California in the second half of 2021. In October Tesla expanded to Texas and last month Tesla added on Illinois.

Tesla is now expanding even further. As of today, Tesla is now offering car insurance in Arizona and Ohio as well.

In a tweet last year, Elon talked about the slow regulatory process for offering car insurance and mentioned that Tesla was looking to offer insurance in New York as well.

The regulatory process for approval to offer insurance is extremely slow & complex, varying considerably by state. Tesla is hoping to offer real-time (based on actual driving history) insurance in Texas next month. Probably next year before we get approval in New York.

-Elon Musk

Tesla determines your car insurance rate using their Safety Score algorithm, which is similar to Progressive's Snapshot rewards. Once you approve Tesla to collect driving data, they'll monitor your vehicle for harsh stops, fast turning, and following too closely.

Your insurance rate will then be based on your driving habits and your chances of getting into an accident.

Some drivers report having much lower rates with Tesla Insurance, while others report that their rate was lower with their current insurance company.

If Tesla offers insurance in your state, you may want to consider getting a quote directly on their site to see if you can lower your premium.
