I guess the difference is "steam build" and "retail build" then and nothing in the game itself that is updated, would need a trainer compatible with either though but the command console has worked pretty well so far though if it's needed I can provide the exe for 18.104.22.168 albeit I do not know if my version (From their website, thus digital retail.) differs from the disc version and what other differences there are.
EDIT: Then again since they can patch every time you launch the game it might also be better to wait a while until the early hotfixes and such are out of the way.

EDIT: Well here's the exe anyway, might as well provide it since I can. Link (Zippyshare, as usual with me.)
