IE9 started from the premise that the modern web will deliver HTML5 experiences that feel more like native applications than sites. Building on hardware-accelerated SVG, canvas, video, audio, and text, developers will use the power of the whole PC to achieve great performance. On the modern web, developers will use the same markup across different HTML5 browsers.
With IE9, we have worked much more closely with the developer community. Developers have had an earlier (and more frequently updated) look at the platform. With that early engagement, developer feedback has had a bigger impact than before. People have downloaded IE9 Platform Previews over 2.5 million times. The samples on the IE Test Drive site have had over 20 million visitors. We appreciate the positive feedback and all the specific issues logged in Connect. They’ve helped us make demonstrable improvements that the community has noticed.
Fully Hardware-Accelerated HTML5
The performance benefits of hardware acceleration are clear from running different sample sites side by side in IE9 and other browsers. Browsers that implement partial hardware acceleration – for example, text-only, or video-playback only, or image-only acceleration – offer inconsistent and possibly unpredictable platform experiences to developers and end-users.
With Platform Preview 4, we’re excited to show highly-interactive and integrated, or modern, SVG. Typically, developers think of SVG as the graphics format for static engineering diagrams and images. With HTML5 and hardware acceleration, SVG is an excellent choice for a new class of interactive, animated scenarios.
Same Markup, and Tests
To assess the quality and completeness of a browser’s standards support, we look to the official standards bodies. Their open, consensus-based process is the best way to bring the community of browser vendors and web developer and design professionals together in building a test suite.
With Platform Preview 4, we’re contributing 519 new tests to the standards bodies. Based on community feedback, we’ve also updated five of the previously submitted tests. This brings the total number of tests we’ve contributed during IE9 development to 2,138.
