After this second Beta, there will be two Release Candidates, one on the 10th and the other on the 31st of January. All these releases are **not** final, they are for testing and should not be used in production...
Hmm, if you count something based on Ubuntu as being Debian based (some people do, some people don't) then I believe that is exactly what KDE Neon is supposed to be!
Hmm.. does it have any telemetry? I'm worried about user data collection. I know Ubuntu has that. It's fairly easy to remove but I'd rather not have it to begin with.
That I'm not sure of unfortunately. From the Plasma side of things I know telemetry has always been specifically opt-in, but I don't know whether KDE Neon has the canonical telemetry disabled out of the box (my gut instinct says it would be disabled, but I have zero proof of this).
