+## __WORK IN PROGRESS__
+This release enhances the diagnostics in Z-Wave JS by adding support for controlling a Zniffer, which allows inspecting traffic from any Z-Wave network. See [here](https://zwave-js.github.io/node-zwave-js/#/api/zniffer) for details on using this API, and [here](https://zwave-js.github.io/node-zwave-js/#/troubleshooting/zniffer) for information on how to create a Zniffer device.
