Chrome 4 opens the door to third-party extensions
Google Chrome 4.0 went from beta to stable yesterday, bringing its support for extension (aka add-on) into the mainstream. As of now, there are more than 1,500 extensions available for power Windows users to add new capabilities to their browser. This is an important capability, and one of the key reasons why Mozilla Firefox attained its market share behind Internet Explorer.
In addition, the latest stable iteration of Google Chrome comes with 1,500 new features compared to the previous version. Bookmark sync with other Chrome browsers is now built-in, as well as a number of APIs and support relating to HTML5 and WebSockets, among other web standards.
Existing users should find themselves upgraded over the week, though they can also check for updates manually. In the meantime, new users can also download Google Chrome here. Unfortunately for Mac OS X and Linux users though, the stable release is only available for Windows--for now.
