An updated platform preview of IE10 for the Windows Developer Preview is now available for download. This IE10 preview adds even more support for HTML5 technologies, enabling richer Web applications with significantly improved performance. IE10’s hardware acceleration of technologies like SVG, CSS3 transforms and animations delivers faster rendering than other browsers, as highlighted in this short video.
See some of the new HTML5 capabilities, performance improvements in IE10.With this fourth Platform Preview, developers can start working with more site-ready HTML5 technologies. You can read the full list here in the IE10 developer guide. Here are a few highlights:
Building HTML5 Applications
This IE10 preview supports CORS (cross origin resource sharing) to allow developers to use XMLHttpRequest to safely request, share, and move data across applications on different domains. This is a common pattern developers use to bring data and services together from different applications. In this test drive demo, you can see how CORS is used along with XMLHttpRequest, the File API, and HTML5 progress control to deliver a smooth experience for uploading multiple files to a service on another domain.
Having the ability to work with binary data and files enables developers to build new kinds of applications and experiences on the Web. This IE10 preview supports blobBuilder from File API: Writer for working with large binary objects (blobs) and JavaScript typed arrays. In this test drive demo, you can see how different file types, including file types which are not natively supported in the browser like PCX files can be read, rendered, and even have their internal contents displayed.
As developers build more sophisticated applications on the Web, they have more need for precise control over how end-users select parts of the page. With CSS user select support in IE10, developers can specify which elements in their page can be selected by the consumer when using their applications. In this this test drive demo, you can see how selection control is applied in a sample blog application using the user-select property in a CSS rule.
Improving Same Markup for HTML5
We continue to contribute to the test suites under development at the HTML5 standards bodies, submitting 118 new tests to them, to further the goal of interoperability and same markup. You can view them at the IE Test Center as well. We strongly encourage all developers to write for HTML5 standards first by always using the HTML5 doc type <!DOCTYPE html> in your pages.
IE10 Preview 4 introduces an updated quirks mode that is more consistent and interoperable with the way quirks modes works in other browsers like Firefox, Chrome, Safari, and Opera. This updated quirks mode supports quirks for page layout, while allowing use of more up-to-date standards features like HTML5 elements for audio, video, canvas, and more.
You can find a full list of new functionality available to developers in the IE10 developer guide here. Download the Windows 8 developer preview to try this update to IE10. We look forward to continued engagement with the developer community and your feedback on Connect.
