Google released Chrome 7, which adds support for installing web apps and for synchronizing web apps. For some reason, Google's blog posts that announce Chrome 7's release don't mention these features:
"In this stable release, we've focused primarily on hundreds of bug fixes. We’ve also included a few other things that may be of interest to developers, such as full AppleScript support on Mac OS X for UI automation and implementation of the HTML5 parsing algorithm, the File API, and directory upload."
{ Thanks, Sterling. }
