The first quick patch today adds some extra features:
Rebindable Keys: the key commands in the game can now be rebound in the options menu to whichever keys the user selects.
Active Pause: there is now an active pause feature so you can pause the game any time when not viewing a cutscene, and you can give orders while paused. The default key mapping for this is the spacebar.
You can now also move the camera with the keyboard (the default is set to the arrow keys, see the options menu for the full list of controls) although since this is an RTS it's advisable to stick with the standard RTS style of using the mouse to drag, edge scroll, or click on the minimap.
Finally, there was one potential bug fix relating to music in the campaign menu.
