That is a "Free" version of the Design Software which I happen to own* a licence for and what I used for the Devboard.
I signed up and will try to open the Devboard Design in it , if it fails I will 'port' it over to circuitmaker then.
That way everyone is free to do changes to it

Not really me but my friendly Ex-Boss gave me permission to continue use one of the company licences for my hobby stuff as a trade
for doing updates to their existing designs occasionally ...
