An IL-2 Sturmovik forum post announces the release of a new patch for IL-2 Sturmovik: Battle of Stalingrad, updating the World War II combat flight simulator to version 1.011 (thanks Olaf). The new version includes a new aircraft and a new map, and also adds the ability to transfer the license for the game to Steam.
