Microsoft has just released a new Internet Explorer Platform Preview that is available for download at the Internet Explorer 9 website. Microsoft has also added a testdrive site that contains a new set of developer samples and information about the upcoming Internet Explorer 9 web browser.
The Acid3 score of Internet Explorer 9 went up to 68 out of 100. Not a perfect score by all means but the developers promise better compatibility in later releases. They do mention that the Acid3 test needs some revamping in their opinion.
A new user string is introduced as well as the capability to change the user agent string in the preview version of IE9.
IE9â€™s default UA string
There are four changes to IE8â€™s UA string that site developers need to be aware of:
Application version is incremented from â€˜Mozilla/4.0â€™ to â€˜Mozilla/5.0â€™ to match other browsers (explained well in the great History of the user-agent string post). This change signals that IE9 is an interoperable browser.
Version token is incremented from â€˜MSIE 8.0â€™ to â€˜MSIE 9.0â€™.
Trident token is incremented from â€˜Trident/4.0â€™ to â€˜Trident/5.0â€™.
IE9 will send the following short UA string without additions made by other software installed on the machine:
Internet Explorer 9 Platform preview installs side by side with Internet Explorer 8. It is not suited yet for general purpose browsing as it is missing many major components including UI elements but also security protections.
The complete list of changes is listed in the release notes in the What’s new section.
