Discontinuing support for browsers older than Internet Explorer 11

Based on this Microsoft post, browsers older than IE 11 on Windows 7 and later OSes will be discontinued after January 12, 2016: http://blogs.msdn.com/b/ie/archive/2014/08/07/stay-up-to-date-with-internet-explorer.aspx?utm_medium=email&utm_source=eloqua&utm_campaign=dt-ajax-lightweight&elq_n=DT_Ajax%20Lightweight-Email_Q3.Email%201

Windows 8.1 and Windows 10 already ship with Microsoft Internet Explorer 11, so there will be no need to upgrade.
