Internet Explorer 11 (IE11) is the last version of the Internet Explorer web browser by Microsoft. It was officially released on 17 October 2013 for Windows 8.1 and on 7 November 2013 for Windows 7. The browser was also shipped with Windows 10 on its release on 29 July 2015, but Microsoft Edge is the default browser in this version of Windows. After 12 January 2016 only the most recent version of Internet Explorer to be offered for installation on any given Windows operating system will continue to be supported with security updates, lasting until the end of the support lifecycle for that Windows operating system. On Windows 7, 8.1, and 10, only Internet Explorer 11 will receive security updates for the remainder of those Windows versions' support lifecycles.
IE11 features redesigned developer tools, support for WebGL, enhanced scaling for high DPI screens, prerender and prefetch. IE11 supports SPDY on Windows 8.1 and newer only. In addition, IE11 supports Full Screen and Orientation APIs, CSS border image support, JavaScript enhancements, DOM mutation observers, Web Cryptography API, video text track support, encrypted media support and an improved HTML editor. IE11 uses Transport Layer Security v1.2 as the default protocol for secure connections and deprecates RC4 cipher suite.
Internet Explorer 11 for Windows RT does not support Java and other add-ons.
In one review, IE11 scored better than Google Chrome 30 and Firefox 26 in two of four benchmarks (including WebKit's SunSpider test), tied for fastest in a third benchmark, and was last in Google's V8 performance benchmark. As a result of the speed improvements, the reviewer said "if you switched to Chrome for speed alone, you're now using the wrong browser."
