+        - Make log levels additive, and add documentation and tests
+          for the setup_log method, which previously had none.
+          Sewn together by t0m from two patches provided by David E. Wheeler
         - Switch an around 'new' in Catalyst::Controller to a BUILDARGS
           method as it's much neater and more obvious what is going on (t0m)
         - Add a clearer method on request and response _context
