Today we’re excited to announce the release of the Internet Explorer Developer Channel, a fully functioning browser designed to give Web developers and early adopters a sneak peek at the Web platform features we’re working on. The Developer Channel is available for download today for both Windows 8.1 and Windows 7 SP1 customers running Internet Explorer 11.Source : IEBlog
IE Developer Channel can run alongside and independently of IE11, and has all of the browser features that you love in IE11, as well as the latest platform features we’re working on. As you test drive these features, make sure to give us feedback through @IEDevChat or Connect.
