• Servers can now force the client to match the server's files, by becoming a pure server. When a server enables sv_pure, clients who connect and play on the server cannot gain an advantage by modifying the game content. For more information about Pure Servers, click here.

• In-game server browser only shows human players in the player counts column. Bots column now shows number of bots instead of a "some bots" or "no bots" icon
  
• Fixed servers with bots reporting incorrect number of bots when sv_master_legacy_mode is set to 0
  
• Fixed a server performance problem with queued packets
  
• Increased the maximum rate to 1 megabyte
  
• Added a findflags console command, which can list all cvars with a specified flag. For example: 'findflags server_can_execute' will find all console variables and commands marked with FCVAR_SERVER_CAN_EXECUTE
  
• Cheat protected many cvars and commands
  
• Removed cl_restrict_server_commands to prevent clients from being redirected
  
• Fixed user names reported as "unconnected" when greater than 32k players had connected to the server
  
• Fixed a client crash during authentication
  
• Fixed a crash when mashing the ~ key on disconnect
  
• Fixed a bug with sv_minrate and sv_maxrate not applying properly on the client
  
• Fixed the free roaming camera in SourceTV demos
  
• Fixed cl_language archiving itself and not updating correctly when the language changed
