Maplists
- The old maplist system has been replaced with an entirely new one, which is configured through UTMapLists.ini, this allows mods using
custom .ini files to have map cycles setup from the ingame menus
- To recover the old server maplist settings, you need to open UTGame.ini and go to the [UTGame.UTGame] section, then for each
'GameSpecificMapCycles' entry you need to find (or create) an entry in 'GameProfiles' under [UTGame.UTMapListManager]
in UTMapLists.ini, which has a 'GameClass' value that matches the 'GameClassName' value in 'GameSpecificMapCycles'.

Then you need to find the maplist in UTMapLists.ini which is specified by 'MapListName' value in the 'GameProfiles' entry,
(e.g: [DMMapList UTMapList]), and then you must manually transfer each map name in 'GameSpecificMapCycles' to the maplist
in UTMapLists.ini.

For example, Maps=("DM-Arsenal","DM-Biohazard") in 'GameSpecificMapCycles' would become:
[DMMapList UTMapList]
Maps=(Map="DM-Arsenal")
Maps=(Map="DM-Biohazard")

- Configuration options for [UTGame.UTMapListManager]:
- GameProfiles: This is a list which is used to define custom game type settings (mainly for game voting), options include:
- GameClass: The FULL class name of the gametype, including package name as well as class name (e.g. "UTGame.UTDeathMatch")
- GameName: The name that is displayed on the vote menu when selecting a gametype (e.g. "Deathmatch", "Warfare - No Orbs")
- MapListName: The name of the maplist that this game profile will use (e.g. "WARMapList")
- Options: Additional URL options which are used when switching to this gametype (e.g. "?WarmupTime=60")
- Mutators: Mutators to be loaded for this gametype (e.g. "UTGame.UTMutator_LowGrav,UTGame.UTMutator_Instagi b")
- ExcludedMuts: Mutators which are disallowed for this gametype (e.g. "UTMutator_Instagib,UTMutator_Slomo")
- bIsTeamGame: Specifies whether or not the current gametype is a team game (used internally for game voting)

- MapReplayLimit: The number of matches which must pass before any one map can be played again
- ActiveGameProfileName: The 'GameProfiles' entry which is currently active; mainly used by the game during runtime
- PlayIndex: A value used for keeping track of when maps were last played, represents the total number of games played
- AutoStripOptions: A list of URL options which are automatically removed upon map change (e.g. "LinkSetup")
- AutoEmptyOptions: The same as 'AutoStripOptions', except these options are given an empty value on the URL (e.g. "GoalScore,TimeLimit")

- Configuration options for [UTGame.UTMapList]:
- Maps: The list of maps used by the maplist, options:
- Map: The filename of the map (minus the file extension)
- ExtraData: An array of arbitrary data which can be associated with each maplist entry; mainly used by the game at runtime
- AutoLoadPrefixes: Maps with the prefixes defined here will be automatically added to the maplist (e.g. AutoLoadPrefixes=CTF,VCTF)
- LastActiveMapIndex: The index into the 'Maps' list which was last active; mainly used by the game during runtime

Voting
- Added support for midgame voting for maps, game types, and mutators.

- All vote related variables have been moved to UTVote.ini
- To recover the old vote configuration values, you need to open UTGame.ini and go to the [UTGame.UTGame] section, then manually
transfer the vote configuration values to the [UTGame.VoteCollector] section in UTVote.ini; the affected values are:
'bAllowMapVoting', 'VoteDuration' (now 'MapVoteDuration' and 'GameVoteDuration'), 'bMidGameMapVoting' (now 'bMidGameVoting'),
'MapVotePercentage' (now 'MidGameVotePercentage'), 'MinMapVotes' (now 'MinMidGameVotes'), and 'InitialVoteDelay'.

- Added new configuration options 'InitialVoteTransferTime' and 'RushVoteTransferTime'; the first slows down the speed at which vote related
data (e.g. maps, game info) is transferred, to spread out bandwidth usage and prevent lag; the second speeds up the remaining
transfers, for when the client opens the vote menu

- Added gametype voting, allowing players to vote in a different game type before voting for a map (if map voting is enabled). Gametype
configuration is setup in UTMapLists.ini, through 'GameProfiles' under [UTGame.UTMapListManager]; configuration options in UTVote.ini:
- bAllowGameVoting: Enable/Disable gametype voting

- Added mutator voting, allowing players to decide which mutators get enabled/disabled in the next match; configuration options:
- bAllowMutatorVoting: Enable/Disable mutator voting
- VotableMutators: The list used to determine which mutators should be votable, options include:
- MutClass: The FULL class name of the mutator, include package name as well as class name (e.g. "UTGame.UTMutator_Slomo")
- MutName: The name that is displayed on the vote menu for this mutator (e.g. "Instagib", "Low Gravity")
N.B. When left blank, the game will attempt to set this automatically
- MutatorVotePercentage: The percentage of votes required to enable or disable a mutator; percentages are only checked at endgame

- Added kick voting; configuration options:
- bAllowKickVoting: Enable/Disable kick voting
- bAnonymousKickVoting: If true, then the voters name is not shown when performing a kick vote (except to admins)
- MinKickVotes: The minimum number of votes required in order to kick a player
- KickVotePercentage: The percentage of votes required in order to kick a player
