Internet Explorer 11


Internet Explorer 11 is the eleventh and final version of the Internet Explorer web browser by Microsoft. It was officially released on October 17, 2013 along with Windows 8.1 and on November 7, 2013 for Windows 7. Windows Vista and earlier are not supported. The browser was also shipped with Windows 10 on its release on July 29, 2015, but Microsoft Edge is the default browser in this version of Windows. It is the default browser shipped with Windows Server 2016 and Windows Server 2019.
Since January 12, 2016, only the most recent version of Internet Explorer offered for installation on any given Windows operating system is supported with security updates, lasting until the end of the support lifecycle for that Windows operating system. On Windows 7 and 8.1, only Internet Explorer 11 will receive security updates for the remainder of those Windows versions' support lifecycles. Internet Explorer 11 was made available for Windows Server 2012 and Windows Embedded 8 Standard in April 2019. It is the only supported version of Internet Explorer on these operating systems since January 31, 2020.

Changes

IE11 features redesigned developer tools, support for WebGL, enhanced scaling for high DPI screens, prerender and prefetch. After launch IE11 got support for HTTP/2. 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.

Removed features

In a November 2013 review by SitePoint, IE11 scored better than Google Chrome 30 and Firefox 26 in WebKit's SunSpider test and Google's WebGL test. It tied with Chrome for fastest in Microsoft's "fish aquarium" benchmark for WebGL and came 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." IE11 was also observed to use less memory with multiple tabs open than contemporary versions of Chrome and Firefox.
In August 2015, SitePoint again benchmarked IE11 in its review for Microsoft Edge, where Edge 12, Chrome 44 and Firefox 39 were also present. IE11 came last in Apple's JetStream test and Google's Octane test but it came second in Microsoft's "fish aquarium" test, after Edge.

History

Though an internal build of IE11 was leaked on March 25, 2013, its first preview version was not formally released until June 2013, during the Build 2013 conference, along with the preview release of Windows Server 2012 R2 and Windows 8.1. On July 25, 2013, Microsoft released the developer preview of Internet Explorer 11 for Windows 7 and Windows Server 2008 R2.
