Internet Explorer 8 public beta 1 was released March 5th 2008.
Microsoft has annonced that Internet Explorer 8 will interpret web pages according to strict W3C standards by default.
Previously, Microsoft announced that IE 8 would use the "IE7 standard" as default, and that interpreting web pages according to strict W3C standard would be a secondary option. This created strong reactions in the web developer community, as the "IE 7 standard" does not completely conform to W3C.
However, Microsoft have now reversed this decision, and it looks like Internet Explorer 8 will be truly standards-compliant.
IE 8 has full support for CSS 2.1. In addition, it fixes "many cross-browser inconsistencies such as get/set/removeAttribute, default attributes, Attribute object and the < Q > tag.
New features:
Activities provide quick access web services. Users can look up and send information from the Web. On a restaurant web site, for example, the user can click within the page to get maps, news, and information about the restaurant, blog about it, or share it on Facebook.
WebSlices is an RSS-like feature that allows users to subscribe to content directly within a page.
