Last month's beta version of Chrome has become the new stable build, bringing a large JavaScript performance improvement to hundreds of millions of Chrome users. While it's a bit meaningless at this stage, this means the stable channel is now version 10, which first appeared at the end of 2010.

The main addition to this version is Crankshaft, a new version of the V8 JavaScript engine that results in 66% faster JavaScript performance -- as measured by Google's own V8 benchmark, anyway. Amongst other changes is the new-look tabbed settings page, sandboxed Adobe Flash for better security, and passwords are now synced with Chrome Sync. For complete release notes, check the Google Chrome Releases blog.

To update to the latest stable version of Chrome, simply close your browser and re-open it -- the update should be applied automatically. Alternatively, click the wrench icon and then About Google Chrome, which will check for the the latest update.
