so to basically fund continued development of my filters, the way I structure things is that full version bumps are paid major updates/overhauls (ie people who bought any 1.X version didn't get 2.X versions for free).
but any .X updates are free, with .5 updates being big freebies.
more to the point though, it's definitely not a bad time to get it or anything. i don't really have the time to do a 3.0 and all my ideas for it are really complex and will take ages to develop. But I do have a couple bugfixes for a 2.8
