When you join or host a game, it will automatically download any patches for the core FAF gameplay or any of the featured mods, which includes the balance testing 'patch'. If the FAF client needs an update, this to is automatic as a prompt will pop up soon after you try running the program.
So to download a patch or any updates, just run FAF and join or host any game. If you want the latest update for any featured mod (Balance Testing, the one for the patch), just host a game with that featured mod. If you do not see any download window, congratulations, you have the latest version.
