EDIT: NEWS FROM MULTIPLAY:
CSS moves to the Orangbox Engine
Jun 23 2010 21:04:07 by ShiningFalcon
Following the BETA period valve have now moved CSS to the Orangbox engine.
Due to the size and complexities of this change we are unable to sort this update tonight.
It will be worked on first thing tomorrow morning. In the mean time if you don't update your game, you will be able to use your servers as normal.
Please note that due to the game changing to a new engine, custom maps and addons may no longer work correctly.
