The CAL sponsored by the CPL (Who works in cooperation with Valve) has posted word on Counter-Strike v1.2 that is due for release this month. We can probably expect changes as usual. The CAL page also has word on a new anti-cheat measure that is included in v1.2

Upon release of Counter-Strike 1.2 this month, the Cyberathlete Amateur League will require all match servers to be in the new "pure" mode during official matches. I wanted give everyone a nice advance notice so you can get used to playing with all the default player skins, weapon models and crosshairs.

Pure servers settings. That should cut down on at least some of the hacks. A pure server setting generally speaking will compare all the files on your drive to the server and if you're running any different models or skins it gives ya the boot. Keep in mind this doesnt have any impact on the wall-hack video drivers. (Unless of course the phrase 'pure server' also encompasses something other than how Q3 works)  Hopefully Valve has something in mind for the wall-hack too.

Speaking of cheats, CAL recently booted a team from their top league for cheating and banned a couple of the guilty player from ever playing in future events. Cheaters = suck.
