Reading Firmware Version / Changelog

[SandroWissmann]

First of all great repo with great docs. I stumbled here by accident because I tried to find out how to interact with the thermostat.

I currently develop myself a C++ / Qt app which I later want to run on a raspberry webserver to control the thermostats via mobile.

I was using the file eq-3-radiator-thermostat-api.md as a reference to know how the commands work to the thermostat because I develop an C++ / Qt app to manager the thermostats.

However I was wondering if a description is missing on how to read the firmware version of the thremostat?

Also I was wondering if there exists some kind of changelog from the manufacturer on what is different between each firmware version?

PS: I also saw in other issues the complains that gattool is deprecated. Im working on manjaro and it is true. But there is an replacement for it. In theory the script could be ported to use btgatt-client which comes nowadays with bluez.
