Hi Neon devs, xkbcommon did a new release 0.7 and KWin will soon start to depend on it. The new release contains new API which was requested by KWin developers. See https://lists.freedesktop.org/archives/wayland-devel/2016-November/031544.html
Since https://commits.kde.org/kwin/d1fdb9a02fb823fe22faef0678bb69963d385d05 KWin requires the new xkbcommon version. It's already part of Debian testing, so hopefully easy to bring into neon.
