Valve are releasing the patches this week (which I *think* will be on Wednesday)..
New client and server updates for Half-Life and Counter-Strike (Half-Life 18.104.22.168 and C.S. 1.5) will be released this week. Both updates include the Ricochet Mod, phase two of the recently introduced anti-cheat technology, a new Counter-Strike map (de_piranesi), as well as various fixes and tweaks. Server files will be released to the public Tuesday evening. Client files will be released for download Wednesday morning at 11:00 a.m. PST, at which point Steam clients will be updated automatically. Those interested in mirroring any of the files, please contact: firstname.lastname@example.org.
