+* Added rake routes for listing all the defined routes in the system #8795 [josh]
+
 * db:create creates the database for the current environment if it's on localhost. db:create:all creates local databases for all environments.  #8783 [matt]
 
 * Generators: look for generators in all gems, not just those suffixed with _generator, in the gem's generators or rails_generators directory. Allow use of the rails_generators directory instead of the standard generators directory in plugins also.  #8730 [Dr Nic, topfunky]
