Consider dropping IE8 in May 2017

[ebruchez]

According to Windows lifecycle fact sheet, Windows Vista extended support will end on April 11, 2017. That's the only OS where IE8 was supported.

After that, the oldest supported Windows OS would be Windows 7 Service Pack 1, which comes with IE10.

This is not quite right due to Microsoft's new policy. With that, "Support for older versions of Internet Explorer ended on January 12th, 2016".

That means IE 11 is the only supported browser, if I read that well, and "Internet Explorer 11 will be supported for the life of Windows 7, Windows 8.1, and Windows 10".

According to this graph from https://www.netmarketshare.com/, there is still about 8% of IE8 on the desktop.

Code which can be removed once IE10 is the baseline:

• JavaScript placeholder support

As of 2017-01-10, IE8 market share has gone down to 3.12%. So this is nicely going down.

IE9 has not moved much, around 5-6%. Maybe because some users migrated to it as well as from it?

We can consider officially dropping IE8 in Orbeon Forms 2017.2 (even 2017.1 might not be unreasonable). Or maybe we should be marking IE8 support as deprecated first, for example in Orbeon Forms 2017.1, to give users a heads-up.

[ebruchez]

According to https://www.netmarketshare.com/, IE9 is back down to ~3% in February.

[ebruchez]

RESOLUTION: We drop support for IE8 for 2017.1. No code is immediately affected, but it means we do not test with IE8 at all anymore.

So closing this.
