When moving to the 0.67 I got the following problems:
Zwave reporting all nodes as ready. Also the nodes which are not connected now for several time (in 0,66,1 dead) and the sensors on batteries (in 0.66.1 sleeping)
The menu to send z-wave commands stayed empty. (configuration -> zwave -> select node -> node config options config parameter)
turning on and of lights still kept working.
reverting back to hassio 0.66.1 removed the problem.
