We're working on a v2 release and will keep this in mind as we implement things.

We just released the v2.0.0-beta 🥳 !

You can start testing it by running go get github.com/auth0/go-jwt-middleware/v2@v2.0.0-beta.

In case of issues fetching the v2 you might want to try go clean --modcache first before doing go get.

I'm closing this pr as now this is part of v2, but feel free to reopen if needed.
