IE8 to pass Acid2 test in default configuration

I am pleased to report that Microsoft has confirmed that IE8 will use "Standards Mode" (and pass the Acid2 test) by default.

Dean Hachamovitch, General Manager for Internet Explorer, has written about the change on the IEBlog.

We’ve decided that IE8 will, by default, interpret web content in the most standards compliant way it can. This decision is a change from what we’ve posted previously.

Why Change?

Microsoft recently published a set of Interoperability Principles. Thinking about IE8’s behavior with these principles in mind, interpreting web content in the most standards compliant way possible is a better thing to do.

We think that acting in accordance with principles is important, and IE8’s default is a demonstration of the interoperability principles in action. While we do not believe any current legal requirements would dictate which rendering mode a browser must use, this step clearly removes this question as a potential legal and regulatory issue. As stated above, we think it’s the better choice.

The rest of this blog post provides context around the different modes, the technical challenge, and what it means going forward.

News.com call out In their coverage a quote from Brad Smith

Microsoft noted that there are some legal reasons for changing course. "While we do not believe there are currently any legal requirements that would dictate which rendering mode must be chosen as the default for a given browser, this step clearly removes this question as a potential legal and regulatory issue," Microsoft General Counsel Brad Smith said in a statement.

I expect that there'll be more IE8 news later this week when Hachamovitch gives one of the keynotes at Mix08.
