Chrome developers are working on several different branches of Chrome, with version 8.0.552.215 yesterday being upgraded to the stable version. Since Chrome has three development channels – stable, beta and developer preview – Chrome 8 will (for now) also populate the beta channel, and the 9.x branch will be the experimental version of the browser.
