IE is the last browser we are supporting at a particular version, see
http://dev.xwiki.org/xwiki/bin/view/Community/BrowserSupportStrategy . For
all the other browsers, we are supporting just the latest release.
We are supporting the latest version of Microsoft Edge since XWiki 9.9,
starting from 24/Oct/17. 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.
We discussed dropping IE11 in the past Oct 6, 2017 (see
https://xwiki.markmail.org/thread/qsrkka6zfrmyxv3d), but the vote failed.
Some updated statistics:
--------------------------------------------------
XWiki.org's 1 year traffic (between Sep 30, 2016 - Sep 30, 2017) compared
to Oct 1, 2017 - May 31, 2018:
- Internet Explorer dropped from (5.84%) to (4.65%)
-- from this percentage, IE 11 usage has increased from (88.43%) to (88.76%)
- Edge increased from (1.56%) to (1.84%).
In terms of Worldwide market share for Desktops, for the past 12 months
(according to
http://gs.statcounter.com/browser-market-share/desktop/ ), we have Sep,
2016 - Sep, 2017 compared to May 2017 - May 2018:
- Internet Explorer dropped from 8.21% to 6.97%
- Edge dropped from 4.3% to 4.15%
In May 2018, Global Market Share Worldwide for All Platforms contains:
- Chrome 58.09%
- Safari 13.78%
- UC Browser 8.16%
- Firefox 5.27%
- Opera 3.68%
- Internet Explorer combined is at 3.08% (with IE 11 having 2.65%. IE11 in
August 2017 had 3.04%)
- Edge combined having 1.91% (Edge combined in August 2017 had 1.8%)
- etc.
--------------------------------------------------
In terms of statistics, IE11 is more used than Microsoft Edge. The only
argument of dropping IE11 is that it's a browser that is deprecated for
about 3 years, and it's limiting the usage of newer specifications (like
CSS Flex, Grid, etc.)
I'm curios about how this period of supporting both IE11 and Edge went, and
if you have other examples of things you wanted to use and are not
supported by IE11.
