On Tuesday, January 12th Microsoft is ending support for Internet Explorer 8, 9 and 10.
According to Microsoft, this means that only Internet Explorer 11 will continue to get updates, as it is the most recent (and last) version of Internet Explorer. IE11 is supported on Windows 7, 8.1 and 10 so if you are using those operating systems, you should definitely upgrade to IE 11.
Note: Apparently Microsoft will still support IE 9 on Vista SP2, should you still be using it.
If you are still using an older version of Windows with an older version of IE, now is the time to stop. I’d recommend you upgrade to Windows 10 as soon as you can; it really is quite nice. As is the new Edge browser.
We are not yet making any changes to our web browser support, so Xojo web apps (as of 2015r4) continue to be supported on Internet Explorer 9+.
