Update v20180424:
AI
Improved AI's economic balance between buildings and army
AI will keep a minimum army size
Improved unit diversity in AI recruitment
Improved AI movement of armies
AI can build naval units
Custom Games
Added ability to set starting era in custom games. All the tech from previous era's is available, and some edicts are already issued.
Ability to have random AI controlled factions. The player still controls whichever faction he selects.
Multiplayer
Added ability to assign factions randomly in MP. All players, including the host, are assigned a faction at random.
Added hidden humans ability in MP. If this is selected, then the UI is adjusted so that no indication is given of which factions are human and which AI controlled. Diplomacy with AI factions has a delay, and functions the same as with human players. Random factions must be selected by the host in the initial faction selection screen for the hidden humans option to be available.
Diplomacy
Reduced offensive alliance diplomatic spam. AI won't ask for alliances against those enemies it can't reach
Can't declare war on vassals if you have a peace accord or fraternal harmony pact with their overlord
Less 1 coin diplomacy
Fixed a serious bug that was stopping inter AI diplomacy working correctly.
Misc
Reduced effectiveness of land troops against naval. Previous fix accidentally doubled it :(.
Fixed a bug that stopped naval units moving adjacent to large land stacks
Buildings can't be deleted if existing or queued building depends on them
Fixed issue with city list not being scrolled correctly in city list view
