 Of course if the function has changed arities or has disappeared
 entirely this may not be feasible, but it should suffice in most
 cases.
 
+Another key change is that `:source-path`, `:resources-path`,
+`:java-source-path`, and `:test-path` have changed to
+`:sources-paths`, `:resource-paths`, `:java-source-paths`, and
+`:test-paths`, and they should be vectors now instead of single
+strings. The old `:dev-resources` key is now just another entry to the
+`:resource-paths` vector that's only present when the `:dev` profile
+is active.

 inspects your argument list to figure out if it should pass in a
