- Added Trophy Case awards category.

- Changed Courtyard Conundrum - qzctf10 The plasmagun and lightninggun have swapped locations.
- Changed Hidden Fortress- qzdm20 Team Deathmatch now only has one powerup - quad, instead of both quad and haste. Free For All now has quad damage and regeneration instead of quad and haste.
- Added cg_deadBodyDarken <0|1> (default = 0) Toggling this cvar on will darken "bright" players as soon as they become corpses.

- Added cg_deadBodyColor <0xRRGGBBFF> (default = 0x101010FF) Altering this cvar allows you to customize the color applied to dead bright bodies when cg_deadBodyDarken is enabled.
- Changed shotgun pattern to use 20 pellets in a diffused 3 ring pattern, each dealing 5 damage for a total of 100 damage.
- Added cg_smokeRadius_NG <0-16> (default = 16) Lowering the value of this cvar will scale the radius of the smoke puffs drawn in the nailgun trails. A value of 0 will entirely disable the smoke trails.
- Added cg_bubbleTrail <0|1> (default = 1) Toggling this cvar off disables the underwater bubble trails drawn behind many bullets and projectiles while underwater.
- Removed cg_noProjectileTrails due to the addition of the cg_smokeRadius_NG and cg_bubbleTrails.
- Added cg_waterWarp <0|1> (default = 1) Toggling this cvar off disables the minor under-water warping effected that exists when submerged underwater. The effect has little impact on gameplay but can be induce disorientation in some players.
- Added cg_zoomScaling <0|1> (default = 1) Toggling this cvar off disables the zooming in / zooming out scaling effect that is used as a transition between your cg_fov and cg_zoomfov; causing the +zoom to act as a quick snap to and from the zoomed fov.
- Added cg_zoomToggle <0|1> (default = 0) Toggling this cvar on alters the behavior of +zoom such that a single key press will enable zooming and a repeated keystroke disables zooming, no longer requiring players to hold the key down while zooming.
- Added cg_zoomSensitivity <float> (default = 1) The value of this cvar is multiplied to our current zoom sensitivity, allowing the user to increase or decrease their sensitivity while zoomed. A value of 0 will revert the zoomSensitivity code to the Q3 legacy code that was previously available in QuakeLive.
- Added cg_drawFragMessages <0|1> (default = 1) Toggling this cvar off disables the "You Fragged So-and-So" centerprint message from drawing on your screen. The shorthand obituary will still print to the HUD to make note of any kills.
- Added cg_buzzerSound <0|1> (default = 1) Toggling this cvar off disables the end-game buzzer sound in all gametypes.
- Changed cg_allowTaunt <0|1> (default = 1) to now also disable gesture events clientside in addition to disabling Team Arena style VO taunts when this cvar is disabled.
- Added cg_lightningStyle <1|2|3|4> (default = 1) Altering this cvar will cycle through various lightning stream effects: Default Q3/QL, QuakeWorld inspired, Team Arena shaft, and thin shaft options.
- Renamed cg_oldRail <0|1> (default = 1) to cg_railStyle <1|2> (default = 1). The new naming structure fits in line with the cg_lightningStyle and the old convention made little sense, as the reference "old" is lost between iterations of the game.
- Renamed cg_oldRocket <0|1> (default = 1) to cg_rocketStyle <1|2> (default = 1). The new naming structure fits in line with the cg_lightningStyle and the old convention made little sense, as the reference "old" is lost between iterations of the game.
- Renamed cg_oldPlasma <0|1> (default = 1) to cg_plasmaStyle <1|2> (default = 1). The new naming structure fits in line with the cg_lightningStyle and the old convention made little sense, as the reference "old" is lost between iterations of the game.
- Fixed "Falling Damage Received when Landing Crouched from Jumppads"
- Optimized cg_drawGun 0 by disabling the weapon sway/position calculations when the weapon is not being drawn.
- Changed cl_mouseAccel, cl_mouseAccelStyle, cl_mouseAccelOffset and cl_maxPackets to now replicate (save to config in database).
- Added cg_newWeaponBar 2 and cg_newWeaponBar 3 options for right and center aligned weapon ammo bars.
