i just finished the yest file it has all of the wyeast, white labs, and all of the most common dry yeasts. the hops file is very updated with lots of new hops and the malt update is something that i found online but is very good and complete.
to install the yeast or hops file open program files, then open promash find the yeast or hop dat. file and move it to a new folder (incase you dont like the updates) then replace the files with the new ones.
to install the malt update open promash go to the grain tab then go to import and find the malt file and import it.
here are the downloads let me know if i missed anything.
