When will nvOC release with ZM included? I'm keen to see the difference

I can't answer that but for those chomping at the bit to try ZM or for those who start with the 19-1.3 image and are missing it, the way to get it (commands taken from 2unix):
cd /tmp
wget --no-check-certificate 'https://docs.google.com/uc?export=download&id=0B3ra23kLdr5lVUJoal9vdV85UDQ' -O v0019-13.zip
cp v0019-13.zip '/home/m1/Downloads'
rm v0019-13.zip
cd /home/m1/Downloads
unzip v0019-13.zip
cd /home/m1/Downloads/v0019-13
pkill -f 3main
pkill -e screen
rm -r /home/m1/zec/zm
mv zm /home/m1/zec
sudo reboot
I chose not to clutter it up with comments but I can if needed. In a nutshell, this code just gets the .3 update package which includes the missing ZM miner and puts it in the location where 3main expects it to be. After doing this, you can toggle your ZM_or_EWBF back to ZM in 1bash and start mining with the new miner.
