This is a bit weird... All official channels from Dero are saying that new Alpha Release must be used but no source code available in the public repository. Why so? Personally I don't like to execute a binary from third parties (even if it's official) without having the change to explore the source code.
Please, publish the last release code!
I've heard that is the plan. They just haven't yet (most likely to maintain their golang edge for the time being)
