No City Trading: Unable to trade cities, cities appear untradable in diplomacy screen
No Map Trading: Maps appear untradable in diplomacy screen
No Wonder resource modifiers: Resources do not affect world wonder or world project construction speeds.
No Immediate Peace (Peace treaty negotiations are only possible after 5 turns)
True AI Diplo: All single player trade items are also available in MP
No war weariness: This deactivates war weariness. Note that all the buildings, tooltips etc. are still active. You just don't accumulate any war weariness.
No score: This fix everybodys score to 1. Therefore no C&D around score is possible.
No unit gifting: You can no longer gift units to other players.
City count tied to espionage: This changes the city count display in the BUG scoreboard. With this it is enabled when you get graphs on other players
Inflation tied to tech: With this Inflation is tied towards tech progess. Inflation still occurs with increasing turn numbers, but in addition if (All techs you discovered / All available techs) * Maximum turn numbers is higher then the current turn, inflation takes the calculated turn from techs as a base for the calculation. This option is mainly ment for games running Advanced Start or Tech Trading.
No Spies: Spies can't be built
No barb cities: No barbarian cities are spawned
No barb water units: No barbarian water units are spawned
Double events: Doubles the propability that an event triggers during each turn.
Quests for everybody: Quests trigger for everybody, who fulfills all the pre-requirements. Keep in mind quests available are still drawn at random at the start of the game.
Changed 'No vassals' option: Colony maintenace is removed from the game
BUG integration
BUG fully integrated
New BUG feature "Grid for graphs"
New BUG feature improved Active advisor screen
New BUG feature show last tick beakers in tooltip
New BUG feature show KTB on tech
Combat log is generated outside the game
Additional bug fixes
Combat log now only writes combats in which you participate
City names can no longer include % in their name. This caused a crash
Fix decay not being reset when decaying to 0 production
Fix decay not counting up, if something is finished this turn
Fix war declaration by third party triggers teleportation of players already in a war
The No Espionage game option now works properly:
GSpy points are converted into Great Merchant points.
Espionage no longer gets converted into culture.
Cultural expansion now happens at normal values.
Spies cannot be built.
Graphs are always visible on contact.
Workboats no longer count as military units for upkeep. They're also no longer considered a military unit so a War Academy will not speed their production.
Trade route turn order bug.
Foreign trade route cities lost permanently when your city using those routes is destroyed (fix is taken from BTS unofficial patch).
Build culture double production.
Build wealth/research/culture + production automation double production.
Proposed trades including cities, where the cities no longer exist to be trades, are not cancelled (note: I consider this a bug because proposed trades are already cancelled if a player lacks the requisite e.g. resources/gold. could be considered not a bug).
Production decay counter on a type of build (e.g. axeman) is not reset after completing one if the next item in the queue is of the same type (fix is taken from BTS unofficial patch).
Feature growth/disappearance rates, and bonus discovery (mine pop) rates, do not scale with game speed.
Diplomacy Pausing: Diplomacy windows do not occur on game login whilst the game is paused.
Autosaves: Autosaves are generated at login and log out; log out saves are saved to a folder specified within the global defines XML file. Default location is C:\temp.
Maximum player number increased to 52
Additional alterations have been made to enable hosting of games on the pitboss server belonging to Zulan. These changes are detailed here
CvCity::init - Building a city on floodplains no longer removes floodplains, they'll still be there if city is destroyed (from Mongoose SDK)

CvCity::setBuildingHealthChange - Fixed several copy/paste and logic bugs affecting bonus building health from events, especially after city conquest (thanks Emperor Fool)
CvCity::setBuildingHappyChange - Fixed several logic bugs affecting bonus building health from events, especially after city conquest
CvCity - Added function getNumActiveWorldWonders()
CvCity::PopOrder - Fixed issue introduced by prior attempt to fix handling of buildings with player limits. Building classes which set iMaxPlayerInstances should now work correctly regardless of what iExtraPlayerInstances is set to. (thanks ztjal)
CvCityAI::AI_yieldValue - Fixed issue causing city governor and AI to heavily weight food when building gold or any other form of commerce. Produced unexpected and poor results for human player, did not help AI either.
CvCityAI::AI_doHurry - Fixed several bugs where AI would incorrectly think it was getting a great deal on a pop/gold rush when it was actually doing the other kind of rush. (thanks Pep)
CvPlayerAI::AI_isFinancialTrouble, CvCityAI::AI_updateBestBuild, and CvPlayerAI::AI_getMinFoundValue - Fixed bug in calculating expenses when AI has negative gold per turn
CvCityAI::AI_cityThreat - Fixed bug when AI is running crush strategy, wrong int was divided
CvCityAI::AI_neededDefenders - Improved efficiency and minor tweaks
CvCityAI::AI_chooseProduction - Fixed bug reducing AI production of workers, and a similar issue for barb players producing too many

CvPlayer and CvDLLWidgetData - Fixed bug where you could acquire unlimited free techs from Oracle or Liberalism (thanks Emperor Fool)
isPotentialEnemy in CvGameCoreUtils - Fixed bug leading to AI launching invasions when unable to declare war, troops eventually got bounced when war was declared
CvGameTextMgr::setBuildingHelp - Fixed issue in mods with display of exposing spies text for buildings which lower espionage defense (thanks Afforess)
CvGameTextMgr (many places) - Fixed issues where unhappiness and unhealthiness from civics or buildings would incorrectly show up as -(unhappy face) instead of +(unhappy face) in several circumstances. (Thanks EmporerFool, Grave, Afforess)
CvGameTextMgr - Game will now properly display info for buildings which generate unhappiness in an area or globally, or produce state religion unhappiness (should these ever come up in mods)
CvPlayer::canFound - Changed handling of founding on water tiles so that Python callback has final say if it is turned on
CvPlayer::removeBuildingClass - Fixed issue with removing buildings when building class was maxed out for some mods (thanks EF)
CvPlayer::canTradeItem - You can now ask AI members of your own team to change religion or civics (thanks denev)
CvPlayerAI::AI_civicValue - Fixed crash bug in multi-player simultaneous turns games created by necessary re-timing of AI_doSplit (thanks to TheOnlyDJCat for debugging help)
CvPlayerAI::AI_conquerCity - Fixed bug where cityAcquiredAndKept event reported wrong player in some circumstances (thanks Maniac)
CvPlayerAI::AI_targetGold - Fixed bug causing AI to not bother with budgeting for expenses for first 40 turns of scenarios and advanced start games
CvPlayerAI::AI_foundValue - Added missing division for iClaimThrehsold (thanks denev)
CvPlayerAI::AI_unitValue - Stealth boats do not make good escorts since they often don't defend, so AI is now very unlikely to use them as escorts for transports.
CvPlayerAI::AI_getHealthWeight - Fixed bug for mods where civics with negative iExtraHealth were evaluated incorrectly (thanks phungus420)
CvPlayerAI::AI_getHappinessWeight - Fixed bug for mods where civics with negative happiness effects from troops, largest cities, or war weariness were evaluated incorrectly
CvPlayerAI::AI_bestPlotEspionage - relevant weights are 0, +- 50, +- 100, so comparison for Agg AI should be < 51 instead of < 50
CvPlayerAI::AI_changePeacetimeTradeValue and CvPlayerAI::AI_changePeacetimeGrantValue - AIs you haven't met yet will no longer get angry at you for trading with their worst enemy (thanks Sephi)
CvPlayerAI::AI_doDiplo - Fixed issue where team is sneak attack ready but hasn't declared war, AI would still demand tribute. If other team accepted, it blocked war declaration for 10 turns but AI still launched invasion and was then bounced when it could eventually declare.
CvPlayerAI::AI_getStrategyHash - Fixed incorrect counting of destroyers as mobile anti-air
CvPlayerAI::AI_getTotalFloatingDefendersNeeded - Fixed poor decision by AI if it has captured one or two cities on someone else's continent, it would minimally defend its new cities
CvPlayerAI::AI_getStrategyHash - Fixed several bugs where player ID was used where team ID was intended
CvPlayerAI::AI_targetCityValue - Fixed issues with valuation of cities with inactive world wonders, multi-holy-cities
CvPlayerAI::AI_commerceWeight - Improved valuation of generating culture in human player cities when culture bar is > 50% (ie, player probably going for cultural victory)
CvPlayerAI::AI_bestTech - Fixed potential rare crash bug in mods where units with no transport capacity can upgrade to units with transport capacity (thanks Afforess)
CvPlayerAI::AI_missionaryValue - Fixed copy and past bug causing overvaluation of missionaries for AIs going for cultural victory early in the game.
CvPlayerAI::AI_unitValue - Fixed potential crash bug in looking up AI_unitValue for UNITAI_MISSIONARY units without passing a valid CvArea*

CvTeam::shareCounters - Fixed bug causing inappropriate overflow research and effectively free techs when forming a Permanent Alliance
CvTeam::addTeam - Fixed bug where, if civs A and B join in a permanent alliance, they get the max of A and B's espionage points against C but C just keeps its point against A and loses its points to B if that's higher
CvTeam::shareCounters - Fixed bug in permanent alliances when No Tech Brokering is turned on, where a civ would often become unable to trade a tech they had researched after entering a permanent alliance.
CvTeamAI::AI_doWar - use bFinancesProLimitedWar for limited war calc instead of max war version
CvTeamAI::AI_calculateAreaAIType - Fixed incorrect index usage (thanks cephalo)
CvUnit::convert - Fixed potential issue in mods where units with transport capacity might upgrade to units without (from Mongoose SDK)
CvUnit::shouldLoadOnMove - Fixed issue with all terrain land units moving onto water tiles with transports in them (from Mongoose SDK)
CvUnit::canMoveInto - Removed strange behavior where setting a unit to be unable to enter a terrain type would be overridden by features (forrest, fallout) (thanks TC01)
CvUnit::isIntruding - Kept 3.17 unofficial patch feature that vassal spies are never caught in master's territory
CvUnit::canAirDefend - Land units which are on transports can no longer defend against air attacks (from Mongoose SDK)
CvUnit::collateralCombat - Kept 3.17 unofficial patch feature which allows mods to enables barrage promotions for collateral damage units

CvUnit::canRangeStrikeAt - Added check for whether target plot is visible (thanks God-Emperor)
CvUnitAI::AI_spreadReligionAirlift and CvUnitAI::AI_spreadCorporationAirlift - AI will no longer airlift multiple of the same kind of missionary or executive to the same target spread city on the same turn
CvUnitAI::AI_paradrop - fixed bug with valuation of terrain bonuses causing paradrops to avoid bonuses in some circumstances when intention is clearly to encourage landing on bonuses and pillaging
