At Google Chrome's first birthday just two weeks ago, we looked forward to an action-packed year for the browser and the web. Thanks to a full year of great feedback from our users, we're kicking off our second year of Google Chrome with a brand new stable release. This release comes hot on the heels of 51 developer, 21 beta and 15 stable updates and 3,505 bugfixes in the past year.
