LXQt 0.9

LXQt 0.9, the lightweight desktop environment (merge between LXDE and Razor-qt), was released this Sunday. The new release drops Qt4 and now requires Qt5.

Besides enforcing Qt5, LXQt 0.9 comes a new LXQt Frost theme, lots of UI and internal polishing and several new features. See the official release note.
