Community Manager Nevalistis posted a list of hotfixes that went live a few days ago. Nothing in the classes department (Mostly Witch Doctor stuff), but general, items and monster bugs that needed to be addressed. The one hotfix that benefits everyone is the random issue with the Greater Rift timer and the BlizzCon 2014 transmog issue.
