Just got my 2018 Bentayga and it has "_S2573 1221" installed. Does the 1221 at the end mean it's Dec 2021? Is there anything newer since? If so, does anyone know what's different about it and if it's worth my going into the Bentley dealer and paying to have the software updated?

Thanks in advance!

 

it is not like open source to get new versions with release notes listed

always is good to get newer version, with fixes, with some level of risk they will broke what was working earlier...

anyway i would update if there are updates.
