Stardock plans to release a new patch for Galactic Civilizations III on Wednesday along with a new DLC pack called Precursor Worlds for the 4X strategy sequel. They actually don't plan on officially announcing this until Wednesday, but they whet our appetites with a few new details on the DLC and the version 1.5 update:

In v1.5, players will now be able to interact with their friends and foes through new and different dialogues and choices. This update also adds a new “Coercion” ability, a new building that will provide a Planetary Wheel improvement for that world, and enhancements to the multiplayer experience, including being able to invite friends to play directly through Steam.

The new DLC, “Precursor Worlds”, introduces new and dangerous anomalies for the player to discover and explore. They will also have to contend with new colony events as they explore lost and ancient Precursor worlds throughout the galaxy.
