OTA Update for Door Module?

Today I noticed one of my w206s had an OTA update available for the app. Unlike past updates, there is no arrow to tap and read a description of the update. Does anyone know what's changed?

The update is only available on my 2023 and not my 2022.

I got the prompt on the main MBUX screen yesterday morning saying that I needed to install the update.
Instructed to click "Install Now", exit the vehicle and lock the doors.
When I got back to the car, there was a message saying the update had installed successfully.

The only explanation is that it will optimize the behavior of the control unit when the car is parked.
I have no idea what the control unit is or what is changed.
I only hope that it prevents the occasional notification that I get when the car is in the garage saying that the 12V battery is critically low.

I had this update carried out directly at the dealership late last year. It relates to the door modules not going to sleep and causing the 12V battery to drain.

Exactly what I was hoping for.

Thanks!

I had the battery drainage problem, and it was solved with a dealer installed update, not OTA

I've included the snip below from my service report which details what was upgraded at the dealership. Hopefully this update is what's being pushed OTA, but I'm not sure if there's an easy way to confirm.
