It wasn’t that long ago that an early version of Internet Explorer 9 – we called it Platform Preview 1 – was announced at MIX10 Conference back in mid-March. If you missed it, here’s MIX10’s Day 2 keynote session, in which the Internet Explorer team’s supreme Kahuna, Dean Hachamovitch, made the announcement (it’s the first part of the keynote, so you don’t have to watch or scan through the entire two hours):
As I wrote back then, IE9 showed a lot of improvements. In addition to the improvements, IE9 came with a commitment made to updating the preview about every eight weeks.
The time has come to announce the release of IE9 Platform Preview 2! The whole story’s over at the latest post to IEBlog, but I thought I’d cover a couple of things I felt were worth noting.
While the Acid3 test isn’t the holy grail – some of its tests don’t mesh with the HTML5 standard as it is right now, others are still “under construction” – more compliance with HTML5 typically means a higher Acid3 score. IE9 Platform Preview 2 currently scores 68 out of a possible 100, which is an improvement over Platform Preview 1’s score of 55, and leaps and bounds ahead of IE8’s scores for 20.
People Issue #1: Standards
Another part of the “Same Markup” approach is working within the various standards groups defining the web experience. Among other things, we’ve been doing things like:
- Co-chairing the W3C HTML Working Group
- Leading the HTML5 Working Group’s testing task force
- Submitting 88 new HTML5 new tests for a grand total of 192
- Joining the SVG working group
- Working with Mozilla on Indexed DB local storage
- Working on the draft for DOM Level 3 events
People Issue #2: Developers
That was a fairly packed room, but that ain’t nuthin’ compared to Todd Anglin’s afternoon session, The Rich Standard: Getting Familiar with HTML5, which went beyond “standing room only” and into the “any place I can park myself” zone:
Take IE9 Platform Preview 2 for a Spin!
You can download Internet Explorer 9 Platform Preview 2 right now. As with Platform Preview 1, it coexists with Internet Explorer 8, and it’s a very thin wrapper around the engine, meaning that it’s really for developer and designer testing rather than general browsing. The UI elements you’d expect in a browser, such as the address bar (you open sites using File –> Open…), nor are the security features such as Protected Mode, SmartScreen filter and XSS scripting filter.
Platform Preview 2 installs right over Platform Preview 1; you don’t have to uninstall Platform Preview 1 before installing Platform Preview 2.
Take it for a spin and send us feedback!
