I guess I'll soon be seeing how well this works with Canary these days, even though I'm in Dev. Dev has been moved up to the same level as Canary (26052). Canary will stay on the same track as Dev for a while (giving people a chance to easily change channels to Dev if they wish) before it shoots ahead to a higher series in some unspecified future week (I would guess at least a couple weeks from now).
Update: What we've seen be a sticking point in the past is the vertical toolbar, but that is not a problem. I initially thought it might be, since it was switched to horizontal (even after I thought I clicked Enable, as usual, post build update), but I went into Control Panel to enable it there, and once the shell restarted it was fine.
