The first UT3 patch is being beta tested for release and the changelog is sure to bring a smile to many a face. Here are the highlights.

    * loaded/saved from the specified subdirectory of Game\Config\
    * - Added QueryPort configuration and command line option.
    * - Added an "AdminChangeOption [option] [value]" console command for server
    * admins. This allows changing most simple .ini values (e.g. GoalScore) from the
    * client. This command will not override URL options. The change will take
    * effect after the next map change.
    * - Added an "AdminPublishMapList" console command for server admins. This
    * overrides the server's map list for the current game type with the one on the
    * client that used the command.
    * - Uses GameReplicationInfo.ServerName if set for the name of the server on the
    * server browser.

Campaign/Co-op:
    * - Fixed a bug that could cause too many bots to be added to co-op matches in
    * some cases.

    * travel. This fixes single player breaking if the host selects the next mission
    * before the clients have finished travelling to the mission selection level
    * - Fixed extra copy of a character when a human player leaves a co-op game at
    * the right time.
    * - Changed network loss during single player to result in player signed in
    * locally.

Modding:
    * - Added a SupportedGameTypes field to UTUIDataProvider_Mutator. If some
    * entries are in this array, the mutator will only be visible in the menus if
    * the selected gametype is found in the array.
    * - Fixed custom gametype midgame menus not being used correctly.
    * - Shipping script compiler now allows localized/config defaultproperties
    * because otherwise autodownloaded mods have no way for their localized/config
    * variables to work.
    * - Added Get/SetSpecialValue() stubs to Object to allow mods to expose values
    * that can be modified without creating a dependancy.
