I got a big red banner when I logged in to my Cube Cart installation a few days ago. It told me that my current version 1.1.0 was outdated and I should upgrade to 1.1.1
I read the release and thought, Great I'll update now.
So I went to Maintenance | Upgrade
And The system says "Your store is currently using the latest version. Please click force upgrade to restore to the default code for this version."
So I tried a "Force Upgrade" and I'm still running 6.1.0
