Upgraded to 2.84 when I was upgrading the firmware on my VEbus devices, few weeks later I noticed all my smart-home integrations had broken, or at least stopped receiving status updates. Upon further investigation, I found that the vast majority of previously existing MQTT topics from 2.73 were missing. After reverting back to 2.73, boom, they were all back again:
Only 2 topics available after upgrade, "P" and "Serial"!
After reverting to 2.73, upwards of almost 1000 available topics!
