We have released a Beta update for Half-Life and associated games.
Changes in this update are:

• Added support for a crcclientdll key in liblist.gam to turn client.dll crc checking back on, useful for 3rd party mods
  
• Make sure the Close button has keyboard focus when you see the disconnection dialog
  
• Made the play command obey speak_enabled cvar
  
• Door movement sound fixes, make sure you stop playing the moving sound if you get disrupted
  
• Fixed crash if you hit retry while in control of a func_tank
  
• Fixed sprays not loading from the correct path causing them not to update
  
• Fixed a crash if you started a local multiplayer game, disconnected and then loaded a save game
