Clojurians Log v2

I am trying to handle multipart file uploads in my compojure app. As far as I understand it I have to wrap my server with wrap-multipart-params [1]. But I can't even refer to this function in the ring.middleware.multipart-params namespace. I am using ring/ring-devel {:mvn/version "1.9.6"} for my ring version. Any ideas what I am doing wrong?
