In the readme there is a disclaimer that states.
⚠️ zenoh has been subjet to a complete rewrite with major protocol updates between versions 0.4.2 and 0.5.0. The Go API does not yet integrate those changes and is only compatible with version 0.4.2 of the zenoh daemon and the underlying zenoh-c stack.
Do you plan to extend the support for the Go libraries so it would support the newer Zenoh versions? Is there some roadmap and expectations about that?
