The kde-next repo is re-opened for the next major update of Qt.
Qt 5.15.0RC is up, along with a full rebuild of Frameworks 5.70.0.
Further needed rebuilds are ongoing, but it is safe to update, since the rebuilds for the Plasma desktop are done.
Not a full Plasma 5.18 rebuild, since [kde-next] will also be used for the upcoming Plasma 5.19RC this coming Monday/Tuesday.
As always, make sure kde-next is the very first repo in your pacman.conf and DO NOT use kde-next if you do not know how to add repo's. This is not for regular user, expect issues & breakage.
