An updated version will be released tonight that includes fixes for the Shell Script action and WiFi evidence source. ControlPlane 1.1.4 introduced a more capable shell script action but broke support for script arguments. The WiFi evidence source contains a bug causing it to hang on to found access points after WiFi is disabled. ControlPlane 1.1.5 will fix both of these issues.
This project is in need of a new maintainer. If you are interested in this let me know via twitter @dustinrue
