+### Version 3+ notes:
+- v3.1.x introduces a breaking behavior compared to prior v3.x releases. In 3.1+
+  in the absense of any CC-Vms or if they are unable to be shutdown, cfops will
+  return an error and exit immediately.
+  - Prior to 3.1 cfops will continue regardless of if it was successful in
+    shutting down the cc-vms
