This article, like everything I've read so far, does not say if MS fixed the problem with SP 2013 not working in IE11 without Compat Mode. And then the next question is whether they support the Edge browser yet.
There is nothing more irritating than a company releasing a new version and wanting to talk about all this goofy stuff like hybrid search or unified code base with online. How about just making the darn thing work with your latest (and recommended) browser first? They should be embarrased SP 2013 works in Chrome but not their own product. And no, putting browser in Compat Mode doesn't count for "works". You know how irritating that is in an enterprise environment, trying to explain to biz users about Compat Mode? I finally gave up and had Corp guys just modify Group Policy to force it for our local biz unit site.
