Patch 1.61 will add a number of new features including; new scenarios and map scripts, unit adjustments and enhancements, and various multiplayer upgrades.  It will also feature a long list of fixes and changes to existing game characteristics.

The new Pitboss Server Application is a dedicated server for online and local games.  It will enable players to log out of a game at any time and log in again to continue their progress from any point.  2K Games hopes this will allow better integration of the epic scope of [i]Civilization IV[/i] into multiplayer gaming.
