+that `bin/rails` and `bin/rake` will automatically take advantage preloaded

 ### Notable changes

+  preloader](https://github.com/jonleighton/spring) is now installed
+  by default for new applications. It uses the development group of

 * `BACKTRACE` environment variable to show unfiltered backtraces for test

+### Spring
+
+If you want to use Spring as your application preloader you need to:
+
+1. add `gem 'spring', group: :development` to your `Gemfile`.
+2. install spring using `bundle install`.
+3. springify your binstubs with `bundle exec spring binstub --all`.
+
+NOTE: User defined rake tasks will run in the `development` environment by

+[Spring README](https://github.com/jonleighton/spring#rake).
