Current firmware EQE SUV

Hello together, two weeks ago I picked up my EQE SUV 350 4matic. It is a storage vehicle. I just checked the firmware level, which is RL_NTG7_E330.602_23063AC3. Now I have already read some articles here on MT, in which higher SW stands are reported. My question is therefore, which is the current version and how outdated is mine? Is an update worth it or is there only a problem with it? Is there an overview of the changes in e have moved in with the individual versions? Unfortunately my dealer is relatively far away – I would have to go to a nearby workshop for an update, then I would certainly have to give a valid reason for the update, right? Thank you for your help.
