[NOTES]
* Pacing has received a large amount of work. Expect to have more of a challenge managing your empire at higher difficulty levels than you did before. Consider dropping a difficulty level if you have problems.
* Existing saves will work correctly. However, the balance pass may make your existing happiness lower than expected when loading into your existing save post-patch.
[UI]
* Civilopedia now available in the Main Menu (under “Other”)
* Replay is now available at the end of the game, and through the main menu. You can choose Map, Graphs, and turn-by-turn. Only games played post-patch will apply.
* Great People progress UI addition (upper-left Info Corner UI).
* Combat preview for Aircraft UI addition.
* Fixed aircraft UI issue causing the aircraft selection UI to duplicate itself when rebasing aircraft.
* When loading save game files, you can now order the list by name, or last modified.
* Fix aircraft UI bug that was causing Nuclear Missiles and Atomic Bombers to leave behind container UI after it’s destroyed.
* Removed dead players from Demographics UI.
[DIPLOMACY]
* Made backstab routine more transparent (the dialog will clearly state that they are backstabbing you).
* AI now remembers when it has been nuked, for a permanent diplomatic penalty.
* AI now recognizes a player that captured their capital for a permanent diplomatic penalty.
* End declaration of friendship as soon as war is declared (so can't later get a notification that it has expired).
* AI remembers if you satisfied one of their requests (positive modifier, decays over time, based on value of items granted).
* AI remembers if you fought against a common foe (positive modifier, decays over time, based on damage done to the common foe).
* Track trades between players and allow that to positively influence relationships (the better the deal for the AI, the stronger the modifier). Particularly useful for bribing a hostile AI.
[AI]
* Rebalanced AI flavors and strategies for unit training to improve AI army composition and build choices.

* Victory adjustments to AI behaviors, including alternate victory paths as “back-ups” (for example, building the Apollo Program, even if they are not going for a Spaceship victory).
* Revise code calculating recommended army size (using smaller armies if the threat is low).
* Correct issue that was causing late-game continent-bound AI’s to over-build units intending to invade, and never properly execute the amphibious invasion.
* Scale recommended army sizes based on difficulty level.
