*SVN*
* 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]
* MySQL, PostgreSQL: database.yml defaults to utf-8. #8701 [matt]
