Hey guys! So the mate-desktop stack recently updated, requiring an update of the deps of the control panel and the panel switcher. With these updates, I'd recommend removing the two packages mentioned above, updating, and reinstalling after the update is done.
Also, recent changes in pamac made it so pamac itself handles aur packages, not yaourt or pacaur, so pamac-pacaur is gone
On top of that, I added plex-media-server, updated pamac, chrome-dev, chromium-widevine, and pepper-flash. Have a great day and let us know about any issues you guys are having either on G+ or in the forum,
