At the moment ie8 is totally broken. I don't want to spend a heap of time making it perfect, but I would like it to be functional.
As far as I can tell, these are the primary issues:
I mean no disrespect, but IE < 11 has been EOL'd beginning Jan 12th 2016. So why go through this effort when its vendor will not even supply security patches anymore?
Because we still have almost 5000 users per month on ie8 (primarily in China). I expect this will decline, but it still a large enough number to justify spending a couple of hours debugging.
JS is not working because jQuery 2.x only supports IE 9+: http://jquery.com/browser-support/
Given that jQuery doesn't work on IE8 nor does l20n.js does it make sense to try and support this still? We're using jQuery to do a "client side include" of content like the login/logout/current-user indicator on each page so that the main content can be cached once for all users, but that additional content can be added post-cache. So unless we come up with a IE8 compliant solution to that, they're not going to be able to access any logged in areas of Warehouse.
Ok, given this complexity, let's drop this for now and respond should we have any significant negative community feedback.
