Microsoft has confirmed that it is working on a new version of Internet Explorer. Among the features in development are the Media Capture API, that lets Web content manipulate audio and video streams from microphones and webcams, the HTTP/2 protocol, currently being developed by IETF, and Web Audio, an API that lets JavaScript process and synthesize audio. The company also plans to implement a JavaScript feature called Promises that should streamline development of asynchronous scripts.
These features and others are listed on the newly updated status.modern.ie site, on which Microsoft lists a whole bunch of up-and-coming Web standards and its attitude towards them.
