Cisco Packet Tracer 7.2.2 is under active development and could be released for download in the next few weeks. Current development build number is Packet Tracer 7.2.2.0000.DEV. Packet Tracer 7.2.2 could be the second maintenance release of Packet Tracer 7.2.
Cisco could continue adding external interfaces to Packet Tracer to make it able to communicate with real network equipments. After having released real HTTP server and real web socket features in Packet Tracer 7.2, the upcoming Packet Tracer 7.2.2 release could bring innovative network interaction between Packet Tracer and Cisco CSR 1000v.
