After what seems like forever, Tesla appears to have finally released the second half of their holiday software update with the deployment of 2021.4.2 this evening.

UPDATE: False alarm, 2021.4.2 only contains bug fixes and minor improvements.

The first vehicles started receiving the update at around 5:00pm PST.


The Tesla stats and software update tracking service Teslascope reported that 75 vehicles on their platform were downloading the update. Similarly, TeslaFi also reported more than 250 vehicles on their service were receiving the update.


There have been no owners who have reported finished installing the new software. We’ll update this article once we learn more.
