Here is a summary:
* The difficulty levels have been adjusted as new gamers were finding it far too difficult. After 6 months of playing Spartan we decided the beta testers were no longer the best source of feedback for how hard the game should be!
* The AI no longer starts with many more resources than the player & no longer rushes player at the start of the game
* The AI maintains production of units into the later game & reacts more quickly to the situation presented by the player & other AI sides.
* The starting positions of some nations adjusted to make them more playable - most notably Sparta/Lacedaimon
* The AI's research choices are now much more balanced allowing the AI to compete with the player on a much more even footing.
* The Persian & Roman invasions are more powerful * A bug where the buy prices for generals & maintenance was incorrect has been fixed
* The AI will no longer attack you without cause. The AI will now only attack its enemies, so careful attention to diplomacy now really pays off.
* Friendly fire casualties have been reduced
* A bug where relationships were not effected by naval battles has been fixed
* The UI & list box behaviour have been improved to work more like Windows
* The AI deployment logic has been improved
* A bug where you were offered the wrong battle resolution options when the AI attacked one of your fleets has been fixed.
* A bug in the diplomacy order descriptions has been fixed
* The formula used for Auto resolved combats has been improved
