 to report new features

Wow, I think this might be the first time I've gotten to witness someone bump
the DRM driver version! I think this is a fine reason to do so though.

One change we should do though: we're going from 1.3.1 to 1.4.1 even though
there's no 1.4.0. So, I think using 1.4.0 would probably be a better version
(unless there's some explicit reason for the .1 that I'm not seeing here).
