• Changed default T-Rex spawn to 1. This is controlled by a console variable. Server admins, if you want to add more T-Rexs change "sv_trex_spawn_count" to whatever number you want.
  
• No MG42 hints for Trigger or the Stygimoloch.
  
• Slight nerf for the Desmatosuchus (tank dinosaur). Splash damage has a smaller radius now.
  
• Desmatosuchus can no longer shoot through walls.
  
• Desmatosuchus can no longer do splash damage through spawn doors.
  
• Auto-glow for medics (when teammates are hurt) now goes on when the teammate is below 50% health. It was 25% before.
  
• Glow outlines on player's no longer display when players leave PVS. This addressed "ghost" outlines that hung around sometimes.
  
• Eliminated bugs related to the T-Rex spawn which screwed up the camera.
  
• Trigger and the Stygimoloch can no longer toss teammates with their melee attack.
  
• T-Rex's no longer get healed by Area of Effect healthkits.

• PIAT rounds no longer collide with teammates right after they're fired.
  
• Fixed bug where capture message stayed up across level loads.
  
• Raptors can now be shot off of teammates after a pounce. To balance, the raptor does more damage on the initial pounce.
  
• T-Rex bite revamped which should greatly improve the ability to eat downed players.
  
• Overhauled the Medic heal function. Now, the heal function is connected to the medkit itself. Medkits can be thrown out with a left-click. But if you go up to a player and right click a heal effect will be "applied" instantaneously.

• Updated the default "Slinger-style" WASD controls to make the character move relative to the isometric perspective.
  Note: In the previous update, this required using a commandline parameter "-isomovement", which is no longer necessary. To restore the original setting, use the new commandline parameter "-orthomovement".
  
• In-game menus now respond to right-clicking as well as left-clicking.
  
• Added support for resolutions greater than 1920x1080, at which visual issues with the background visuals could occur.
  
• Fixed several issues that were causing the game to crash for some players.
  
• Fixed an issue in Burstone Quarry that could cause players to get locked out of the level's final area.

• Fixed an issue causing the opening splash screens to overlap when running the game using the "-nofixedstep" commandline parameter, which unlocks the frame rate.
  
• Fixed a rare issue where weapon slots at the Arsenal could become unselectable.
