The only thing I can complain about with this is that it doesn't have the new stuff added to the Tau codex, but as the only really new thing I actually use is the Fireblade, it's a minor issue.

EDIT: Ah, Battlescribe, it's like Army Builder without the hilariously bad price tag. I got pretty much my entire club hooked on Battlescribe after getting the store owner to endorse it. I hope the guy working on a file set specifically for our club gets it done soon as the files most of us are using right now have a lot of redundancy and errors.
