Yeah, we do the thing asked for wrt support - as in, 10 will still get another update, our documentation is a bit overzealous right now. Which is fine, ppl should upgrade sooner rather than later…
We don’t really describe what release is in what channel as it changes all the time.
Generally, you’ll see ‘stable’ go to the next release once it is out gradually, with us stopping the roll-out if a bad bug is found.
we DID find a problem, it’s a buggy third party client problem but we want to try and work around that. So 12 isn’t available for all 11.0.x users. It will come quickly after 12.0.1 is out (end of the month) though.
Production will come a while after, 12.0.2 maybe but possibly sooner if 12.0.1 proves to not have any more serious issues.
