3.28.5 - September 21, 2018 =========================== This release is intended to fix video playback on YouTube. We believe that YouTube began requiring media source extensions to play WebM videos on Tuesday of this week, so we have enabled it. You are strongly encouraged to update to WebKitGTK+ 2.22.2 and the forthcoming GStreamer 1.14.4 to minimize video playback disruptions. It's not really reliable enough to be enabled yet, but it's a whole lot better than no YouTube.
