Ciphreon Nope. Solus doesn't use beta versions of software unless absolutely necessary (or for some reason gives the users a much better experience).
While in the case of KDE Plasma there often is a testing repository available, even that is never the beta version, just the .0 version (AFAIK)
With GNOME the maintainers usually wait for at least the .1 release before pushing it to the repository.
