After my success running MATE panel on Mir last week, I continued to develop discuss that PR. I’ve nailed down a number of small bugs and edge cases, but there are still more to go. I’ve also exposed a few minor issues in Mir, which I’m working to resolve.
@alan_g has restructured what we publish to the different Mir kiosk snap channels. The edge snap now provides what’s in the devel ppa, beta is from the rc ppa and the candidate channel is the currently released version of Mir.
