lates OTA update on EQS580

I purchased my EQS580 in February of 2022 so I just passed 1 year. To my knowledge, I have only recently received my first OTA Update and it mentions some graphics and some sort of Google integration but I cannot find any documentation on what was actually updated. Is there any place to find this information? I would love to know what has changed AND has anyone seen their battery life go down after the update? I have lost about 20+ miles after charging to 80% after the update.
