Microsoft announced that it is now configuring the settings in Internet Explorer 8, the upcoming version of its browser, to render content, by default, using methods that give top priority to Web standards interoperability.

Internet Explorer 8 has been designed to include three rendering modes – one which reflects Microsoft’s implementation of current Web standards, a second mode reflecting Microsoft’s implementation of Web standards at the time of the release of IE 7 in 2006, and a third mode based on rendering methods dating back to the early Web. The newest rendering mode is preferred by Web designers, while the other modes are present to provide compatibility with the myriad sites across the Web that are currently optimised for previous versions of Internet Explorer.

"IE8 has been significantly enhanced, and was designed with great support for current Internet standards. This is evidenced by the fact that even in its first Beta, IE8 correctly renders the popular test known as ‘Acid2’ which was created by the Web community to promote real-world interoperability ,” said Ray Ozzie, Microsoft chief software architect. “Our initial plan had been to use IE7-compatible behaviour as the default setting for IE8, so as to minimise potential impact on the world’s existing Web sites. We have now decided to make our most current standards-based mode the default in IE8.”

"This is obviously a complex issue, with important considerations on both sides,” said Ozzie. “On one hand, there are literally billions of Web pages designed to render on previous browser versions, including many sites that are no longer actively managed. On the other hand, there is a concrete benefit to Web designers if all vendors give priority to interoperability around commonly-accepted standards as they evolve. After weighing these very legitimate concerns, we have decided to give top priority to support for these new Web standards. In keeping with the commitment we made in our Interoperability Principles of being even more transparent in how we support standards in our products, we will work with content publishers to ensure they fully understand the steps we are taking and will encourage them to use this Beta period to update their sites so as to transition to the more current Web standards supported by IE8.”
