How about something like 'ffly ver 2'? Or maybe put in the year: '2015 ver', or if necessary, '2015 ver 2'.
And, what do you name the 3rd version (& beyond)? A 'more-diff ver'? Or maybe 'differ ver'?
Or, more seriously, 'ver 3'?...
I still think if a database (such as dcm) has only one version, then it's not 'diff'. Maybe it's 'upgraded', or 'replaced', or 'new', or 'improved', or 'now gluten-free', but if it's the only one, it's not different than anything else on the site.
