The v2.3 patch is already out and brings a number of improvements to both the base game of Galactic Civilizations III and Stardock's Crusade expansion. That Crusade expansion is seeing new missions, AI improvements and some game balancing, as well as bug fixes. For the base game, the patch brings improved diplomacy, planetary improvement balance, some tweaks to default settings, with additional performance and AI optimizations. Galactic Civilizations was originally released over 4 years ago and it's great to see continued support for one of the better 4x games out there.
From the press release, for Crusade:
New Content: New missions for galactic exploration and a new "Mogul" promotion have been added.
AI Improvements: The AI is substantially better at managing domestic affairs (improvements, economy, etc.), as well as issues abroad (waging war, exploration, etc.).
Game Balance: Many adjustments to the game's balance through changes to missions, bonuses, ideology, and more.
Bug Fixes: These corrections adjust bugs and crashes that have been reported by the Stardock community.
And for the base game:
Diplomacy: The AI is much better at bargaining with players and makes more intelligent trade offers.
Balance: A balance pass on planetary improvements now gives them an increased effect on gameplay, though it has also made them more expensive. Adjustments have also been made to the cost of specialty vessels such as constructors or colony ships.
Galaxy Setup: More anomalies are available to explore early on in the game than there were before. The number of planets, stars, and habitable planets have also been substantially increased.
Performance: Some of the optimizations for Crusade have been ported over to create faster turn times and improve the general framerate.
AI: The AI has been improved to be able to play more intelligently, especially during times of war
