The `/v4` version will be backwards compatible with existing `v3.x.y` tags in this repo, as well as
`github.com/dgrijalva/jwt-go`. For most users this should be a drop-in replacement, if you're having
troubles migrating, please open an issue.
You can replace all occurrences of `github.com/dgrijalva/jwt-go` or `github.com/golang-jwt/jwt` with `github.com/golang-jwt/jwt/v4`, either manually or by using tools such as `sed` or `gofmt`.
