As promised, the version 1.1.0.9 patches for Half-Life and version 1.0.0.4 patches for the retail edition of Counter-Strike are now available for download. This release offers the new Anti-Cheat protection, HLTV changes, integration of Steam technology, a bunch of bug fixes and other changes. You can use the SierraUp utility (from the "Configuration->Update" menu) that was distributed with previous releases, and participants in the public Steam beta test should be able to upgrade around this time as well.
