I found, and managed to get this working on Fedora 27, and I would love to know if it is still being maintained. I could try to reverse engineer the java version I have, to keep it current for the next expansion. I would love to do away with windows completely, and if this works well, I may be able to. Recent changes to wine have increased the fps in WoW to a point close to native windows. This addon updater is a good replacement, since twitch has never come with anything that runs on linux, so I hope someone updates this, or at least points me to the original source code, to let me try to build it on linux.
