You heard it somewhere else first: IE8 reportedly passes the Acid2 test. I’ve seen many reports of this, but none of them have read between the lines and translated it into an implicit set of new features for IE8’s HTML and CSS support: proper object support with content fallback, min- and max-height and width, CSS tables, and generated content. It also implies bug fixes for collapsing margins. These are the things tested by Acid2 which would’ve failed in IE7. If we get as much on the JavaScript side as we’ve apparently received on the HTML/CSS side, this will be the largest step forward the web has seen in a decade.
