What it really means is that you are now using Silicon Labs EmberZNet v7.2 (7.2.x.x) Zigbee firmware which by default uses EZSP v10 (EZSP PROTOCOL VERSION 10) and that protocol version is not yet supported by the bellows radio library which is what the ZHA integration depends on for talking to the interface of Silicon Labs based Zigbee Coordinator / Zigbee stack like the Home Assistant SkyConnect radio adapter/dongle/stick.
That is all OK though since the interface is backwards compatible with EZSP v9 which bellows support.
