And you use letters for bug fixes, i've always liked that idea of version releasing.
Like
1.05g
1 = First major update
.05 = 5 minor updates
g = a,b,c,d,e,f,g = 7 bug fixes.
Looks confusing but makes sense, if this was using Badspots method it would be version 13, and it piles up after a while and you get like version 807656, and that's just moar confusing.
