Microsoft have released the first update to version 1.6 a short while ago
This is the first update that can use the new auto update of gateways
We didnt have autoupdate enabled so all gateways want a update
Enable and Save 
and a few seconds later the gateway agents starts to update , and 5 minutes later here all agents are updated
Very Very Smooth
