The evolution of IE from Internet Explorer 7 to Internet Explorer 8 spans from the graphical user interface on the surface of the browser to the underlying rendering engine. Among the various improvements delivered to Internet Explorer, enhancing AJAX in the browser is an illustrative example of Microsoft's efforts to take its proprietary browser to the next level. In this regard, Sunava Dutta, IE Program Manager, revealed that the Redmond giant focused on improving AJAX for IE8, on top of what was made available with the Beta 1 release in March. The AJAX updates are already available as of the release of IE8 Beta 2.
         “The good news is our team has been working since Beta 1 to tweak and update our implementations based on feedback from developers and ongoing updates to the W3C standards drafts on which most of these implementations are based or have been submitted for consideration. Not content with doing just that, we also added a few new features for developers. The AJAX updates we’ve chosen for Beta 2 focus on maintaining cross-browser compatibility and the feature sets that developers have thought would be the most useful,” Dutta explained.
