The x.org website doesn't say anything about a new release, so it seems the
commit log is even wrong. Which means the relevant code might cause
anything from slow preview-rendering to completely broken previews when
using any of the X11 open source drivers on a default X11 installation
(i.e. without EXA enabled).
