All WaypointIDs from previous * savegames are invalid. Use STATION_INVALID instead of WAYPOINT_INVALID * \li AIWaypointList constructor now needs a WaypointType similar to AIStationList, * it can also handle buoys. * \li AIVehicleList_Station now also works for waypoints * \li Stations can be build over rail without signals that is in the right * direction for the to-be built station. It will also convert the rail if * the station's rail type supports the old type. * \li GetAPIVersion() was added as function to info.nut. If it does not exist * API version 0.7 is assumed. This function should return the major and * minor number of the stable version of the API the AI is written against. * For 0.7.2 that would be 0.7, for 1.1.3 it would be 1.1, etc. * \li The subsidy logic has changed. Subsidy is now awarded when cargo * originating from subsidy source is delivered to station that has subsidy * destination it its catchment area. One industry tile or one town house * is enough as long as station accepts the cargo. Awarded subsidies are no * longer bound to stations used for first delivery, any station can be * used for loading and unloading as long as cargo is transferred from * source to destination. * \li Make AIEngine:CanRefitCargo() not report refittability to mail by * default for aircraft. It is not necessarily true. This means that even * if the aircraft can carry mail (as secondary cargo) it does not return * true if the aircraft cannot carry it as its only cargo. * \li Improve behaviour of AIEngine::GetCargoType(), AIEventEnginePreview::GetCargoType() * and AIEngine::CanRefitCargo() for articulated vehicles. For * CanRefitCargo true is returned if at least one part can be refitted. * For GetCargoType the first most used cargo type is returned. * \li AIIndustryType::GetConstructionCost() now returns -1 if the industry is * neither buildable nor prospectable. * \li AIEngine::IsValidEngine will now return true if you have at least one * vehicle of that type in your company, regardless if it's still buildable * or not. AIEngine::IsBuildable returns only true when you can actually * build an engine. * \li AITile::GetCargoProduction will now return the number of producers, * including houses instead the number of producing tiles. This means that * also industries that do not have a tile within the radius, but where * the search bounding box and the industry's bounding box intersect, are * counted. Previously these industries (and their cargoes), although they * produced cargo for a station at the given location, were not returned. * \li AIRail::BuildRail will now fail completely if there is an obstacle * between the begin and end, instead of building up to the obstacle and * returning that everything went okay. * \li Orders for buoys are now waypoint orders, i.e. instead of using the * station orders for buoys one has to use waypoint orders. * \li Autoreplaces can now also be set for the default group via AIGroup. * * \b 0.7.5 - 0.7.4 * * No changes * * \b 0.7.3 * * API additions: * \li AIAbstractList::SORT_ASCENDING * \li AIAbstractList::SORT_DESCENDING * \li AIAirport::IsAirportInformationAvailable * \li AICompany::GetPresidentGender * \li AICompany::SetPresidentGender * \li AIEngine::GetDesignDate * \li AIStation::GetConstructionDate * * Other changes: * \li AIs are now killed when they execute a DoCommand or Sleep at a time * they are not allowed to do so. * \li When the API requests a string as parameter you can give every squirrel * type and it will be converted to a string * \li AIs can create subclasses of API classes and use API constants as part * of their own constants * * \b 0.7.2 * * API additions: * \li AIVehicle::GetReliability * * Other changes: * \li DoCommands and sleeps in call, acall, pcall and valuators are disallowed * * \b 0.7.1 * * API additions: * \li AIAirport::GetPrice * \li AIController::GetVersion * \li AIOrder::AIOF_DEPOT_FLAGS * \li AIOrder::AIOF_STOP_IN_DEPOT * \li AIOrder::IsCurrentOrderPartOfOrderList * \li AIOrder::IsGotoDepotOrder * \li AIOrder::IsGotoStationOrder * \li AIOrder::IsGotoWaypointOrder * \li AISignList * \li AITile::CORNER_[WSEN] * \li AITile::ERR_AREA_ALREADY_FLAT * \li AITile::ERR_EXCAVATION_WOULD_DAMAGE * \li AITile::GetCornerHeight * \li AITile::GetMaxHeight * \li AITile::GetMinHeight * \li AIVehicle::SendVehicleToDepotForServicing * * Other changes: * \li GetURL() was added as optional function to info.nut * \li UseAsRandomAI() was added as optional function to info.nut * \li A limit was introduced on the time the AI spends in the constructor and Load function * * \b 0.7.0 * \li First stable release with the NoAI framework. */
