Patch 1.11 for Command & Conquer: Red Alert 3 was released in June 2009, despite the changelog being mistakenly set to May 2009. This was the final patch that brought extensive changes, as patch 1.12 was merely a hotfix.
The downloadable patch executable includes all the patches that were released before it.

User Interface Enhancements

Made several improvements to the way garrisoned buildings and captured structures are reported through shroud (in game and on the radar).
