I have just upgraded to V3beta4 and noticed some strange behaviours that were not there in V2.2
1) When trying to add a probe, if you click on "type", the box drops and closes again immediately so you can't select anything.
2) Device tree doesn't nest correctly
3) Strange behaviours in the Device menu. If you click between the different options eventually the Dude client hangs and you have to crash the application
Apart from that seems good, syslog feature is great
