Does anyone know what source git locations do the Neon releases (user, dev-stable and dev-unstable) use to build?

I'm mostly looking for the difference between dev-stable and dev-unstable.

I believe the user edition builds off KDE published release source packages and not off git?

dev-unstable: git "master" branch (or equivalently unstable)

dev-stable: git branch from which the next stable release will be derived. this can be the same as unstable (e.g. kde frameworks only maintains a master branch) or a different branch if stable releases happen from a different branch (e.g. for plasma it is Plasma/5.6 right now and Plasma/5.7 after)

user: not built from git at all but from final released tarballs
