While the majority Chrome users have been upgraded to Chrome 10, Google is fitting the bugs from Chrome 11 and working on Chrome 12. A recent Chromium build made a significant change: Gears is no longer incorporated in Google Chrome.
Gears is a browser plugin free by Google back in 2007, The initial goal was to add hold up for offline web apps, but the plugin added many other HTML5 features at a time when HTML5 wasn't a main concern for most browsers. Google discontinued Gears last year to center on "bringing all of the Gears capabilities into web standards like HTML5" and to apply them in Google Chrome. Features like geolocation, notifications, web workers, application caches are previously available in Google Chrome, so it's almost certainly the right time to stop bundling the Gears plugin.
"With all this now available in HTML5, it's lastly time to say goodbye to Gears. There will be no new Gears releases, and newer browsers such as Firefox 4 and Internet Explorer 9 will not be supported. We will also be removing Gears from Chrome in Chrome 12," informs Google.
What's astonishing is that important services like Gmail and Google Calendar still use Gears to work offline. Other services like Google Docs and Google Reader dropped offline support last year. Google promised that they will use HTML5 features implemented in browsers like Chrome or Firefox, but that hasn't materialized yet.
