Check it out here http://www.pgmusic.com/ When I first started using BIAB on the Mac in the late 80's there was only 1 update per year and sometimes only every other year with a few style updates between and no changes to the app itself but I guess they are like all of the other software companies times are hard so they are releasing single point incremental upgrades that in years past were free.
As far as I could tell just skimming over the update info all they've done is add some more real instruments/styles. Maybe there's more than that but it sure seems like a ploy to get some Christmas cash
