This is a rewrite of almost everything. The provided modules no longer rely on undocumented/deprecated behavior. It's no longer possible to have multiple DNS "servers" on different sockets, but the new version allows serving arbitrary records. Records can be defined in the config or Caddyfile. The provider communicates with the Server via a channel.
