Is the new update interoperable with the previous version?
Yes; products built with the ZigBee Feature Set can participate in a ZigBee PRO Feature Set network as end devices and visa versa. Products built with either a ZigBee Feature Set platform based on the ZigBee 2006 specification or a ZigBee Feature Set platform based on the updated specification, are fully interoperable at the network level. As before, end-to-end interoperability is achieved using a Public Application Profile with either Feature Set.
