The benefits are that you will be on a supported release.
Ok, well that doesn't sound like an awful lot of benefit given i'm not in an enterprise environment. Given that every single OMV release-update i've done in the last 10+ years has resulted in needing to rebuild from scratch, I'm not keen on updating for updatings sake. I no longer have the time or the patience to spend days on troubleshooting/rebuilding.
I would have thought that there would be some other improvements/new functionality etc which would justify the new version number.
Thanks for your reply.
