HTML5 support and a continuation of work begun on IE9 will be key features of Microsoft's next version of Internet Explorer.
Dean Hachamovitch, corporate vice president at Internet Explorer, announced the first Platform Preview 1 for IE10, which is available for download, claiming that IE10 continues on IE9's path, directly using what Windows provides and avoiding abstractions, layers and libraries that slow down users' sites and experience.
He said: “The only native experience of the web and HTML5 today is on Windows 7 with IE9. We released a fast, clean, trusted and interoperable IE9 globally for consumers and businesses four weeks ago with the goal of delivering the best experience of HTML5.
“The best HTML5 is native to the operating system, so websites have the fewest translation layers to pass through. The best HTML5 enables sites to use the same markup, the same HTML, CSS and script across browsers. The best HTML5 respects developers' time and enables same markup by treating site-ready HTML5 differently from unstable technologies.”
He said that development of IE10 began about three weeks ago and based on the progress that has been made, he wanted to start engaging the development community now.
“At the MIX conference, we showed the new browsing engine along with several new browser test drives that anyone on the web can try out. You can run these at www.ietestdrive.com to see emerging standards like CSS3 Multi-column Layout, CSS3 Grid Layout and CSS3 Flexible Box Layout, CSS3 Gradients and ES5 Strict Mode in action. We also demonstrated additional standards support (like CSS3 Transitions) and CSS3 3D Transforms that will be available in subsequent platform previews of IE10, which we will update every 8-12 weeks,” he said.
“Also available are new test drive samples for today's production browsers. For example, Fishbowl is an update to the original FishIE tank that now uses more HTML5 technologies. Paintball is another great demonstration of what fully hardware accelerated HTML5 Canvas delivers.”
Hachamovitch also said that while IE9 includes support for many emerging, but not yet final standards (such as font embedding, performance measurement, and privacy) that are stable enough for same markup to work consistently, other emerging standards such as WebSockets and IndexedDB need to stabilise before developers can expect that.
He said: “Ultimately, the point is advancing the interoperable web and making the web better. Developers want robust HTML5 implementations that they and their sites can rely on, in which the same markup works consistently. Our focus has been on enabling the same markup by delivering native HTML5 to Windows with full hardware acceleration and working closely with the standards bodies and the community.
“IE10 builds on full hardware acceleration and continues our focus on site-ready web standards. This combination enables developers to deliver the best performance for their customers on Windows while using the same, web standard markup across browsers.”
