Can anyone explain channels?

Edge was introduced for experimenting with a more up to date software foundation (Unity, Mir, libhybris, etc).
You could call it a glimpse at the future but it will be unstable und potentialy risky to use.
These are nightly builds.

Thanks fot claryfying this doelf. Have you got any idea how the stable version relates to development version? Fot example I use UBPorts (stable) version 4, while I can see that under development section there is U Ports version 111 available. I just wonder if the stable 4 equals to former dev 4 with all bugs removed, or is stable 4  being for example dev 25 or something like that?
