The zip file you download contains all the files for the release. If you've cuxtomized templates or created players and games then you'll want to upgrade rather then just unzip this release into a directory.
You should take the AutoTroll.exe, AutoTroll.chm, AutoTroll.hlp and AutoTroll.cnt from the zip file and place them in the root of your existing AT directory installation. You won't get any new templates that might become available - but you can see a list of thosein the Release Notes.
