I updated my app to phx 1.4 Every thing is working fine but when i run test cases. It gives me warning for almost every test case.

        warning: Elixir.Phoenix.Controller.render/4 with a view is deprecated, see the documentation for render/3 
          for an alternative
        (phoenix) lib/phoenix/controller.ex:719: Phoenix.Controller.render/4
        (app) web/router.ex:8: App.Router.token_auth/2
        (app) web/router.ex:1: App.Router.__pipe_through2__/1

        (app) lib/app/endpoint.ex:1: App.Endpoint.plug_builder_call/2
        (app) lib/haitracker/endpoint.ex:1: App.Endpoint.call/2

I didn’t see any changelog regarding to the render function.

Any suggestions?
