A new version 1.6 of the Weapon Mod for Quake III Arena "new minor additions and changes to the mod are grapple pull speed, drop weapons after being fragged on/off, /drop weapons while playing will spawn up above the player, 3 sec rule is gone, and offhand grapple. players can choose the type of grapple they want using the two client console commands, /onhand and /offhand." There's also a note there about a bug in lightening discharge code in version 1.6 that's been removed, though it's not clear if that means the version 1.6 they have for download has been altered from the first version that was posted.
