What to do if Tesla update release notes are blank

November 10, 2019

It's been a while since, every time there's a new software update, I get blank release notes. I've seen quite a few people asking about this on social media, so I wanted to share how I do it to see the release notes after a software update.

What's in Tesla's software update 2019.36.1

November 5, 2019

During this past week, Tesla has started rolling out the software update 36.1. We’re not amongst the lucky ones who got it and it seems like now they’ve stopped distributing it. My guess is that they have found a bug and that we’ll see a .2 or .3 version being released in the next few days. 36.1 introduces some very attractive updates...

5 things to know before buying a Tesla

October 23, 2019

When I took delivery of my Model S, the very friendly and knowledgeable person who walked us through the ins and outs of the car told us 'Remember, a Tesla is still a car'. Every time I talk to someone new to Tesla I use that piece of advice. This post is about things that are fundamentally different in a Tesla car from any other car. Things about both the car and the experience of buying one.

2019.12 - Updated browser, software on demand, new games and more

2019.12 has been released to a few cars - surprisingly 2018.8.X is still releasing - and it brings a tesla browser, more Atari games, and the highly expected feature to download new software on demand. Honestly, reading the release notes we can’t tell if going forward we are going to be able to ask our car to download the newest software or if it would need Tesla to stage it as they do now. If is the later, I guess this is useful for folks not always on wifi or to know if something is wrong with your car and you should call your SC, but if is the former, we are really looking forward to it!

2019.16 is scheduled to be pushed on today (Thursday May 16th)

According to a support representative, 2019.16.1 should start releasing by the time you get this newsletter. Thanks to our great verygreen we know what is coming with 2019.16.1, and while it brings a lot of good stuff, it’s introducing some limitations for Tesla owners in Europe. According to the release notes:

  • Due to new local regulations, the limit of how far the steering wheel can turn while Autosteer is active has been adjusted. This may reduce Autosteer’s ability to complete sharp turns.
  • To initiate Auto Lane Change, the turn signal must be engaged to the first detent (held partially up or down) and the lane change must start within 5 seconds of engaging the turn signal.
  • Your phone must be actively connected to your car via Bluetooth while using Summon.

You can release the rest of the release notes here. Honestly, if I were in Europe I would wait to see what great things 2019.16.1 brings before updating.

2019.16 release notes

The release includes several goodies, I would recommend you to read the whole thing, but here are a few highlights:

  • Sentry mode has a new setting to keep it always on and exclude places
  • Set your software update preference and let Tesla know that you want them to send new software updates to your car as soon as they become available for your car and region
  • Conditional Speed Limits are now displayed - if they apply to your current road - under the regular speed limit sign. I assume this still doesn’t include cameras recognizing the speed limits but who knows

2020.16.2.1 and Pedestrian animations

The latest software update 2020.16.2.1 brings some UI changes to the Tesla Toybox and filters for charging but it also brings pedestrian animations. @blktsla shows us it all in his new video.

DragTimes has tested the new Cheetah Launch Mode with a Raven Model S and shared their impressions in this video: «Easier to engage launch mode and stays on longer before disengaging (~10seconds vs ~5seconds previously); can do more 14 mile consecutive runs before it starts to have overheating issues». See it in action!

Acceleration Boost Upgrade

Want faster acceleration 0-60 mph? No problem. Tesla has confirmed that all AWD Model 3s with version 2019.40.2 or newer can now upgrade to improve their acceleration from 4.4 to 3.9 seconds. Just wow.

Apple announces support for EV routing in Maps & new Car Key NFC unlock feature in iOS 14

Apple just announced a couple of interesting features for EV cars at the WWDC20, good to see Apple moving in this direction. The first one is support for EV routing in Apple Maps. The second one is Car Key, which will allow to wirelessly unlock your car with your iPhone and iWatch. The feature is part of the newly revealed iOS 14 and it will work over NFC. The advantage is that it would allow NFC car unlock up to 5 hours after your phone battery dies. Great backup to using Bluetooth as a primary key. No news about if Tesla is going to integrate with it or not, since they have their own system to use as your Tesla Key.

Definitely feel the boost with the 'acceleration upgrade'

Folks who have already purchased the ‘acceleration upgrade’ seem to be happy with it. ‘Chill’ and ‘Standard’ modes are now ‘Chill’ and ‘Sport’. A few owners are saying they wish they’d be an option in the middle (like chill, standard, sport) since ‘Chill’ is just too slow.

Do you need wi-fi for downloading new firmware?

There are a bunch of theories about what is necessary and what is not to download new software. Thanks to dennis_d and XXX - who have root access to their cars - we got some insights about how downloading new firmware works. Here are some of the details:

  • Tesla pushes a job ‘ firmware update’ to your car, the job says that it needs to wait for wifi to start the download process, the job usually says for how long it needs to wait for the wifi to start the download. After that date, the firmware can download over LTE.
  • If ‘Energy Saving Mode’ is enabled the car needs to be charging - maybe plugged does the trick? - or it would only download data 1 hour at the time, we assume to let the car sleep in between downloads.

Note: Map updates are different, they require wifi.

Future feature: WiFi garage door opening

A few months ago, Tesla stopped including Homelink in all their cars and made it available to purchase after delivery. Just this week, Elon said on Twitter that soon the car will be able to open a WiFi garage door- obviously for ‘smart’ garage doors. This seems great given that Homelink costs $300 on the Tesla store. WiFi remote openers sell for about $40 and full on WiFi garage door openers for $200.

How many miles have you driven in AP?

Another Twitter promise, this time about a section to know how many miles have you driven with AP. It would be even cooler if they expose this via their API, I’m sure some folks would do cool things with that info!

How to tell your car to check if there’s an update available

Some people say it’s a coincidence, but hundreds of people have reported this tip from Zack to actually work. If you want to help your car checking if there is a pending update, just tap a few times on the ‘Advanced’ button in the software menu. This only checks if the update is there, which in theory the car should be checking anyway. However, I’ve seen that not being really accurate, instead Tesla has to have approved your car configuration and region to get the update.

New in 2019.8.3 - Autosteer stop light warning

Although no one seems to have been able to trigger that and record it into a video, it is in the release notes. Thanks Earl for sharing it!

From issue #52

New Software Update 2018.28.1

The release notes don’t include anything exciting but according to dennis_d - who is famous for seeing release notes that people can’t see - it includes the AP trial that Elon mentioned a couple of months ago, fixes traffic rendering on MCU1 as well, and seems to be unlocking the new navigation for all remaning MCU1 cars.

We assume Tesla is keeping the big guns for v9 we don’t expect the versions between now and the release of v9 to have many big improvements but even the small updates are welcome!

New update 2020.16 with ability to format a USB drive in the car, new Toy Box UI, and more

Tesla has started rolling a out a new version, 2020.16. This is not the update of the Traffic lights and stop sign detection, but a newer one which has barely started getting to people just yet. The main changes introduced in this version are:

  • Dashcam Viewer improvements: ability to format a USB drive in the car
  • Redesigned UI of the toy box (see video below)
  • Ability to filter charging stations by power
  • Improvements to Backgammon Game

A new software update is rolling out and it brings Model 3/Y owners (and everyone else with MCU2) a new videogame to play in your car: Fallout Shelter. 2020.20.1 also brings Theater and TRAX improvements (let your creativity run wild!).

We installed 2020.20.1 earlier this week and, unfortunately, for our Model S with MCU1 and AP2.5, it does not bring any new features 😢

We haven’t had a chance of trying the Dashcam Viewer ourselves but we have spoken with owners who installed the update- thank you @CodingMark- and it looks very neat. One thing we discovered is you can actually watch any movie/video from your USB drive or storage device in your Tesla’s screen now 🤯

Tesla started (and already stopped) releasing 2019.36.1.
