Tesla's 2023.26 update, which is now available on most vehicles, arrived with several exciting features, including a Spotify player refresh, support for Bluetooth controllers on the Model 3/Y and the rumored Charge on Solar feature for Tesla Solar and Powerwall owners.

The update also included smaller enhancements, such as the multi-cam view in the Tesla app, the ability to automatic turn on the headlights when the wipers are in use (available in select regions) and more.

For the new Model S and Model X, the update also added some features that were previously available on the Model 3 and Model Y, such as the customizable scroll wheel and the ability to reposition the Blind Spot Camera on the center display.

However, most Tesla updates also include smaller improvements not mentioned in the release notes. Owners slowly discover these changes over time, and we've outlined them here.
