Code Issues Activity

Renamed SteamStub variant 2.0 to 2.1. This is a major change due to a file being presented that looks to be an earlier version of the 2.x variant. This new (older) file presents like 2.x however, it predates some more common features such as the XTEA encryption seen in 2.1 and newer. This version seems less feature-rich and thus I feel it's actually 2.0.
