Sins of a Solar Empire Trinity/Diplomacy has just received a giant patch with a few dozen changes included. The patch brings the game up to Version 1.3 and while most of the changes are for gameplay and balancing, there are a few tweaks to the game's graphics, interface and AI.
Perhaps the biggest change has to do with compatibility. By patching your game to version 1.3 you'll lose access to any previous replays and game saves. That means you'll want to finish off any games you may have in progress before applying the update.
