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.
What It Means
A recent Tesla update had version number 2021.32.201b7f33580a5f. 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 has begun rolling out some map updates, including a brand new geographic area. These updates include two regional map updates, with one confirming Tesla’s entry into India and the other improving the maps in Europe.
Indian Launch
The biggest addition is a new map region for India, which was discovered by Tesla hacker Greentheonly. This move, while seemingly minor, is a prerequisite for Tesla launching vehicles in the region.
For years, discussions about Tesla’s arrival in India have focused on manufacturing plans, import duties, and retail store plans. However, the vehicles themselves must all be technically ready for the region.
This is more than just data entry; it involves integrating local points of interest, Tesla’s internal routing logic, and displaying regional road information correctly. In past market entries, Tesla has activated the necessary navigation regions in its software shortly before officially launching in a country, and just this morning, news broke that Tesla will open its first showroom in India.
On July 15th, Tesla will open its first showroom in Mumbai, marking its entry into the Indian market.
For those who have imported Tesla vehicles in advance of the official market entry, this means they will finally receive official maps and navigation support, and will likely begin receiving official software updates in the near future.
European Maps Update
In addition to the India map update, Tesla has also starting roll out a map update for Europe. The new map update for Europe is version EU-2025.14, bringing users up from EU-2025.2.
You’ll need to connect to WiFi in order to download map updates and similar to software updats, Tesla will roll them out gradually. If you want to learn more about map updates, be sure to check out our Tesla maps and navigaiton guide.
This map update will likely be fairly minor, but it should include newer roads, speed limits and more details. It could also include additional information that’s required for launching FSD in Europe.
While map updates aren’t as exciting as FSD updates or major software updates like the upcoming Grok AI update, they’re especially useful for Tesla owners who travel on new roads that may not be in Tesla’s current map version.
Tesla has officially scheduled its 2025 Annual Shareholder Meeting for Thursday, November 6, 2025. The date was confirmed in an 8-K form filed with the US Securities and Exchange Commission this week. Shareholders can expect to begin receiving official notifications by email or letter this week.
While we don’t know what, if anything, is up for vote this year, shareholders should ensure their investment accounts are linked up at ir.tesla.com if they plan to vote on upcoming proposals.
While these meetings cover standard corporate governance, they’ve also become a key venue for Tesla to share updates on its future projects.
Let’s take a look back at Tesla’s 2024 shareholder meeting to see what we can expect for 2025.
A Look Back: Shareholder Meeting 2024
The 2024 Shareholder Meeting was packed with news and updates. Some of the highlights included details on Cybercab, the first mentions of AI5, and the move of Tesla’s incorporation to Texas following the re-ratification of Elon’s 2018 compensation plan.
The 2025 meeting may provide progress updates on several key items.
First up is the final status of Elon Musk’s pay package. While it was successfully re-ratified following the 2024 Meeting, the Court of Delaware ruled against it, creating a legal situation that resulted in Tesla amending its letter of incorporation and moving to Texas.
While the messy legal situation hasn’t been completely sorted out yet, there’s a chance we could see more on this at the 2025 Meeting.
Next up is a status update on the Robotaxi Network pilot, as well as progress for Tesla’s Cybercab program. We’ve seen early prototype castings for the Cybercab outside Giga Texas, and they recently provided an updated timeline in their 2024 Impact Report. This is going to be the next big step for Tesla’s growth as it starts its Robotaxi service business.
The Tesla Semi and Tesla Energy are also two massive programs undergoing upgrades and revamps. The volume production of Semi is supposed to begin by the end of 2025, and Tesla is constantly working on expanding Tesla Energy’s manufacturing footprint to meet the never-ending demand for Megapack and Powerwall. We’re anticipating some major updates here, along with some updates on Tesla’s next-generation battery tech, including the Gen 3 Cybercell that includes dry-cathode manufacturing.
There’s a lot to be excited about - and November 6th is the day we may find out a lot about Tesla’s future products. The meeting will be a big event that we’ll cover in detail, so don’t worry, even if you miss it. We’ll have a full set of recap notes and longer in-depth articles following the event, as usual.
