Add known working firmware versions to Readme

[407pilot]

Would it be possible to add a complete list of known working software versions for v2, pan, v3 to the Readme? Perhaps in the update log?

It is kind of suggested that he is releasing for latest firmwares, unless otherwise noted, and also trying to keep most backwards compatibility. Is there a specific firmware that it’s not working for for you?

it's maintained so that latest firmware version is always supported by latest hack version. I tried my best to maintain backward compatibility but it's not thoroughly tested so older firmware might run into issues.
