For those HL owners using CS Mod, make sure to use the HL auto update utility (you can get it here on MG). I used this tool myself and it works very well - especially if you're not sure which patch you need.
Keep in mind that there will be no CS mod 1.2, it will go right to 1.3. CS Mod 1.3 and CS Retail 22.214.171.124 will be out in a few weeks, if not longer. Remember that these are the patches that will incorporate Valve's new Voice Communication technology and multicast spectator.
