Version 2.2.4 is supposed to help with a lot of C-7 zwave issues. It has a lot of changes/improvements in it specifically targeted at C-7 zwave in any case - hopefully they fix a lot of issues. 
I'm optimistic they will.
No ETA on timing for it, though, that I've seen. Could be a day, could be a week, could be a month. 
Depends on how fast they squash the bugs and get it to a quality that is ready to publish.
