Once again, lol: *You will always be on the lastest version/season regardless of whatever version of the installer you used.*

Forward.5 is the most current season and that's the season you'll be on if you were to start playing right now regardless of what installer you used. On April 17 your game will automatically update to Frontier G. Being on the latest version is not optional.
