[AD] 4.2.0 release demo

[Evert Glebbeek <eglebbk@xxxxxxxxxx>]

As we're supposed to have this new demo for 4.2.0 and don't want to hold up 
the release for it and I probably won't have time to get it in shape in 
time, does anyone else think it's good form to remove the old demo from 
the 4.2.0 release?
