Now Tesla has released a new software update that allows those vehicles with the new design to charge at peak 250kW rates at their V3 Superchargers.

At the time of the announcement by Musk, it wasn’t clear when exactly the change occurred, but thanks to this software update and Tesla hacker @greentheonly, we now know it is for Model S and Model X vehicles with -H and -G 100kW battery packs that were manufactured from June onwards.

The update also includes the recent Passenger Face Vent improvement, that disables the passenger vent if no passenger is detected in the seat.

Tesla Arcade has also been removed from some vehicles based on their location, but it is not known yet which regions are affected.

Update: It looks like only Tesla owners in Hong Kong have had the Tesla Arcade removed.

 

Update #2: This 2020.28.5 update also includes the ability to go 5mph (10km/h) over the speed limied when Traffic Light and Stop Sign Control (TLSSC) is enabled.

Here are the full release notes according to Teslascope.

Sirius XM Improvements

In this release, we have made improvements to the interface of Sirius XM to allow easier usability and discovery of stations, enhanced categorization of content, and improved the overall navigation experience.

Please note: You must have an active subscription to listen to Sirius XM. Please see Subscription Tab for details.

Traffic Light and Stop Sign Control (Beta)

When Traffic Light and Stop Sign Control is enabled, the Autosteer cruising set speed on residential roads can now be increased up to +5 mph (10 km/h) over the speed limit.

Supercharger Improvements

Your car is now able to charge at V3 Superchargers at up to 250kW peak rates. As usual, when you navigate to a Supercharger, your car will condition its battery during the drive, so it can charge faster.

Range Display

Your car will now display a slightly higher range to more accurately reflect the capacity of the battery.

Passenger Face Vent

Your car will automatically disable the passenger face vents when no passenger is detected, lowering energy consumption in hot weather. This vent can be manually enabled by tapping where you’d like the passenger face vent to direct air within the climate control panel.

Suspension Improvements

For improved ride comfort, the maximum allowed speed and ground clearance in HIGH and VERY HIGH have been reduced. Please refer to the Owner’s Manual to find more details.

New Language Support

You can now select Polish as your language. To update your language setting, tap Controls > Display and select the desired option from the Language drop down menu.

Note: Your vehicle must be in PARK to change languages.

Tesla Arcade

Due to local regulations, the Tesla Arcade has been removed from your car.

This release contains minor improvements and bug fixes.
