-- This repo uses community-driven JWT package [github.com/golang-jwt/jwt](https://github.com/golang-jwt/jwt), which is now [officially recognized](https://github.com/dgrijalva/jwt-go#this-repository-is-no-longer-maintaned) successor to the original `github.com/dgrijalva/jwt-go repository`.
-- The upstream repository [switched to `github.com/lestrrat-go/jwx`](https://github.com/go-chi/jwtauth/releases/tag/v1.1.0), which is a major breaking change that might lead to lots of code refactoring.
