So far so good!
All the lighting effects seem to be working correctly (I've tried Static, Reactive, Arrow Flow, Wave and Ripple).
One thing I've noticed, is the colour control slider is a bit buggy and the stops don't move all the way to the left or right.
Overall though, dramatic improvement over the previous firmware
If I notice any other oddities I will post them here.
EDIT: Recording a macro crashes the software and doesn't pick up any keys
