The most responsible thing to do for everyone's benefit is to just release v5 with SIV, so I present to you all, chi v5 at `github.com/go-chi/chi/v5`. I hope someday the developer experience and ergonomics I've been seeking will still come to fruition in some form, see [golang/go#​44550](https://togithub.com/golang/go/issues/44550) - History of changes: see
