The reason for the lighting not following the deck is the XZ uses external mixer mode, and I'm sure you've come across the forum post where this was discussed, along with potential work-around options until our rekordbox team implements a MIDI control for it. (Currently the solution is a keyboard shortcut, and then use an app to turn MIDI commands into keyboard inputs.)
And yes, there have been other DMX updates - in fact, rekordbox 6 includes several:
- 3 manual DMX panels
- custom interlude scenes
- pan/tilt restrictions
It's not discontinued, there's lots more to come!
