If your existing system is working well without any problems then no need to update.
If you are installing a new system, then it is a good idea update to the latest version.

If you need features from xxxx2yy (like some assistants) then change to that version.
If you do not need features from xxxx2yy the stay with xxxx1yy.

Hi, it’s a secondhand to be build in yet. But basically you are saying don’t upgrade except if needed ?

It will be a new installation, so then it is a good idea to upgrade to the latest version.
