really not all that much but they did update the graphics and added a calculator window that has different sections to calculate numerous things during a brew day. I.E. tons of different Mash calculations for sparging rates, infusion rates, strike temps, infusion rates, and a ton of other preset calculations. Added shopping list might be helpful to some. And overall better organization of recipes. To me I am happy with the update and can't complain Beer Tools Pro has always been pretty much dead on with the numbers it sets for my setups (once you calibrate your vessels and heating sources).
