Changed:
* Names of the difficulty levels now fit what they feel like for new players instead of what they felt like before the AI improvements.
* New easy AI can now once again declare war on the player. But they will not consider other players relations and they will never declare war on the player when he already is at war.
* New medium AI no longer has dramatically reduced chance to declare war on the player. But they will not consider other players relations and they have dramatically reduced chance to declare war on the player when he already is at war.
* The diplomatic penalty for capturing cities has been normalized to be relative to the average population rather than the population of the previous city owner. This will reduce the likelyhood of a dogpile against the one who got the last city.
* AI will consider habitat provided by suburbs as slightly less valuable and expand a little more.
* AI will now consider the alien aggression settings of the game when considering when to expand. They expand earlier on settings below "very high".
* AI will now build colonizers and formers when at war but their military power is strong compared to that of their enemies.
* When AI has a storage of food and doesn't need to farm, it will now assume an average yield of 3 to prevent it from building useless farms in that period.
* AI will now build more aircraft units in inland cities when there are a lot of coastal cities.
* AI no longer considers standings and war status of other factions when deciding its diplomatic actions.
* AI will be far less aggressive towards weak players they like and more aggressive towards players they dislike, even if those are really dangerous.

Fixed:
* Fixed an issue that allowed the the AI to know whether a city was undefended or not without having vision.
* Fixed incorrect difficulty level description texts for dutch, french, german and italian.
* Fixed an issue where it was possible for the AI to sign contracts or ask for tribute in the same turn that it would declare war.
* Fixed an issue where AI would not determine the coastal to inland city ratio properly and thus underproduce naval forces on archipelago maps.
* Fixed an issue where AI would never attack cities when they didn't have access to artillery units yet.
