Internet Explorer 11 is the latest incarnation of Microsoft's browser for Windows 7 users (it's already built into Windows 8.1).

The new release places a major focus on performance. JPEG decoding and text rendering is now done on the GPU; HTML 5 prefetching and pre-rendering helps to get pages ready before you even click the link; Chakra, IE's JavaScript engine, is 4% faster than previously (and it was already very fast before).

New or enhanced support for a host of web standards will help to extend the browser's capabilities. WebGL can create interactive 2D and 3D environments, for instance; Media Source Extensions (MSE) allows IE to automatically switch video bitrates depending on network conditions, delivering smoother playback (although only on Windows 8.1 at the moment); the browser can now download video without caching it to disk, extending battery life; and support for the HTML Full Screen API means videos can now fill the screen.

Elsewhere, extended support for more HTML5 and CSS properties will make web pages look better than ever; the developer tools have been redesigned; and there are various other smaller fixes and tweaks (Microsoft says IE11 "includes extensive improvements to the built-in text editor", for instance, although we're not sure exactly what they are).

There's nothing revolutionary here, but IE11 does include some welcome performance enhancements
