Gen2 firmware actual update - MQTT new commands

First of all, I would like to thank Shelly for constant support and firmware updates.
Gen2 0.14.0 beta1 version is currently available. In the changelog it is stated that "MQTT Control Additional topics which allow commands to be sent to the device as well as for publishing results". Is there somewhere to find out more details, which topics have been added and which commands have been added? Thank you in advance for your answer.
