As you"ve probably already heard, this new version of Counter-Strike adds two new rifles, the Galil and Famas, a new riot shield for Counter-Terrorists, a new map (de_airstrip), updates to old favorites de_inferno and de_aztec, and a whole bunch of other minor tweaks and bug fixes.

Update:
Steam Beta 2.0 Admission Suspended
The Counter-Strike and Team Fortress communities have maxed out the Steam 2.0 beta servers, resulting in the temporarily suspension of admission to the beta as more content servers are put online. The current Steam content servers offer over 500 megabits of bandwidth, all of which the community is consuming right now.
Anyone interested in hosting a Steam content server should email biz@steampowered.com. (Content server requirements can be found at www.steampowered.com.)
Those who have already joined the beta are encouraged to continue their participation and submit their feedback
