This post has details on update 3 for Master of Orion, which has just gone live in the early access version of the 4X space strategy game. The new version adds espionage gameplay, the Darlok and Silicoid races, a new economic victory condition, support for Linux, and more. They also warn that the large number of changes mean save games from early access version 2 may no longer work, so they are offering the previous Windows and OS X build separately to allow players to continue. Here's word: "After a lot of work we are proud to present this massive update. As you will see this version is packed with important new features, new playable races and several improvements. We want to thank you all for your amazing feedback that is helping us improve the game."
