Major Updates

Mouse Wheel Support: While Opera and Explorer were already providing mouse wheel support, Chrome was lagging on this part till now. Personally i would never want to do the cumbersome task of using horizontal scroll bars, especially if the webpage is too lengthy. 

Better View: Now with this version users can browse in full screen mode and zoom the pages to the full extent. It could make the user distract free browsing and make it enjoyable.

Interface Improvements:  This version introduced auto form filling, which is very much useful to cut down the repetitive task of filling your personal information in registering with websites, which ask just too much details to get access to some blocked resources.

Faster Performance: This is the major improvement as this version provided 35% faster executing JavaScripts and the benchmark was tested on SunSpider.
