v5.0.0

Compare Source

• chi v5, github.com/go-chi/chi/v5 introduces the adoption of Go's SIV to adhere to the current state-of-the-tools in Go.
• chi v1.5.x did not work out as planned, as the Go tooling is too powerful and chi's adoption is too wide.
  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
• History of changes: see go-chi/chi@v1.5.4...v5.0.0
