The Savage 2: A Tortured Soul Website has word on a new version 1.5.1 patch that's now available for S2 Games' action/strategy sequel. The new version includes "a ton of polish and bug fixes, as well as some key balance changes," all outlined in this Change Log, which makes it clear this patch does not incorporate recently promised performance improvements (story). They also announce that next week will be a free-to-play week in the game:

For the week of July 21-28, we are lifting all restrictions on demo accounts. Savage 2 will be completely free to play for the full week with no restrictions.
