The kde-next repo is in use gain, this time to get ready for KDE Applications 16.08
The first beta is uploaded (minus kdepim, still building).
As always, to use kde-next you will need to have the build repo enabled too.
Place kde-next first in your pacman.conf, followed by build then the rest.
If you do not know how to edit your pacman.conf, then please do not use kde-next, editing is by far the easiest part of helping in kde-next.
