Two years ago, I created the new repositories at, used with<pkg>/v3 where <pkg> is one of conn, cmd, devices, or host. I kept the old ones to not break existing users. The problem is that it creates more confusion than anything else and people get stuck on the old code base. As such, I am pushing v3.7.0 that deletes the whole code in the old repository

If you want to keep using the old code base (which doesn’t support Raspberry Pi 4), stay on I recommend against and instead follow the instructions at the post from 2 years ago.
