I released the next minor version of https://kellnr.io which support the display of crates, cached from crates.io, in the UI now. For the first iteration of that feature, they are only shown and searchable in the crate overview and a click forwards to crates.io, as not all meta information is stored in kellnr, for cached crates. That may change in the future, if someone requests it.

Starting to port the Nodejs HTTP router https://github.com/delvedor/find-my-way to Rust, for practice.
