* A new server administration menu made by Dusk, enabling RCON
users to change server settings within the menus and without
needing to use the console.
* A new private chat mode so that players can send private
messages to each other (or the server), using "sayto" or
"sayto_idx". The server can decide on whether or not private
messages are allowed with the CVar "sv_allowprivatechat".
* Various netcode improvements, especially with the unlagged.
* An option for players to send up to 3 backup copies of older
move or weapon select commands using "cl_backupcommands".
Particularly useful for players suffering from bad packet loss
on a server.

"sv_country" instead of launchers always relying on GeoIP to
determine their location.

SetGameModeLimit, SetPlayerClass, SetPlayerChasecam,
GetPlayerChasecam, SetPlayerScore, GetPlayerScore, InDemoMode,
ExecuteClientScript, NamedExecuteClientScript,

GetMapRotationSize, and GetMapRotationInfo.
* New ACS EVENT script types: GAMEEVENT_CHAT,
GAMEEVENT_PLAYERCONNECT, GAMEEVENT_ACTOR_SPAWNED,
GAMEEEVENT_ACTOR_DAMAGED, and GAMEEVENT_ACTOR_ARMORDAMAGED.
* New SBARINFO commands: IfSpectator [not] [dead] and
