[xwiki-devs] [VOTE] Drop support for Internet Explorer 10/11 + Adding support for Edge

Hi devs, This mail is about: A. Dropping support for IE10 B. Dropping support for IE11 C. Adding support for Microsoft Edge --- If you read our Browser Support Strategy ( http://dev.xwiki.org/xwiki/bin/view/Community/BrowserSupportStrategy ) we are still supporting Internet Explorer 10. We started its support since Jun 17, 2015. In practice we don't perform full tests on IE10, focusing mostly on IE11. The last performed tests for IE10 where in Jan 2017, for XWiki 8.4.4 ( http://test.xwiki.org/xwiki/bin/view/QA/XWiki%208.4.4#|t=qa&p=1&l=1… ). On another note, Microsoft Edge replaced Internet Explorer as the default web browser since the release of Windows 10 (launched Jul 2015). Internet Explorer 11 is maintained on Windows 10 for compatibility purposes, but is deprecated in favor of Edge and is no longer actively developed. Instead of supporting "Internet Explorer 10.x-Latest" + "We support IE browsers, starting with version 10." we actually should say (in case the vote is passing) "Internet Explorer 11 + Microsoft Edge". We might even considered dropping support for IE 11 and just keep Microsoft Edge, since that's the latest version of Windows supported browser. Although, IE11 currently still has a better usage than Microsoft Edge. I could not found any performed tests for Microsoft Edge on our test wiki. --- In terms of xwiki.org website usage for the past 12 months, we have: - 5.46% sessions for Internet Explorer -- IE11: 91.50% -- IE10: 2.80% - 1.43% sessions for Edge (multiple versions) In terms of worldwide market share for the past 12 months (according to http://gs.statcounter.com/browser-market-share/desktop/ ), for desktops, we have: - 8.21% IE - 4.3% Edge Usage example for August 2017: - 7.1% for IE11 - 2.26% for Edge 15 - 1.37% for Edge 14 - 0.2% for Edge 13 --- So my votes are: A. Dropping support for IE10 +1 B. Dropping support for IE11 -0, because of bigger usage compared to Microsoft Edge. Still, I don't think we have the man-power to support tests on both browsers types. C. Adding support for Microsoft Edge +1, because this is the latest supported browser for Windows Thanks, Caty
