Kuchiki is unmaintained

[SimonSapin]

This is to let you know that your dependency https://crates.io/crates/kuchiki will not receive new versions. I’ve archived its source repository: https://github.com/kuchiki-rs/kuchiki#archived

No immediate action is required as I’m not planning the yank the crate. If and when you look into replacing the dependency, I’d like to encourage you to experiment with data structures since Rc+Weak is only one of many ways to represent trees in Rust.
