I also noticed the new "pause" feature when printing.
I like that now for the UM2 - unlike pause in UM1 - the head moves up and out of the way before pausing.
Some questions/issues on pause:
1) When pausing it seems it takes a while (buffered?) before it actually pauses. Is there a way to calculate how long it will take? Is is a specific number of line segments/gcode lines?
2) I cannot find a way to change filament during a pause. I think that most people would use pause to change filament. Of course it could be useful for other things as well (inserting objects into a print etc) but I really think it needs to be possible to change the filament.
Feasible to implement? The Replicator 2 has this feature I think and it would be nice if we had it too.

I just downloaded the RC3 and upgraded a UM2 with the firmware (which the printer says is 14.02.1).
After running a very short print (only 0.1mm layer), at the end the print stopped and then the timer counter counted down for a few second...and then it started displaying 6 hours. Still the head was still and not moving, also still heated bed and hotend heated.
I waited only a minute or so before I aborted.
Not sure it matters, but this was a print with Initial layer thickness 0.1mm and I had cut off object bottom enabled as well.
I.e. with the cut-off it was 0.1mm high, otherwise 0.2mm high.
I'm guessing this is a firmware bug?
Did not try this print with previous/other firmwares though.
