I have a Rails app that was created using Rails `3.2.6`. Now that `3.2.8` has been released, is this all I need to do to update the app?

1. Edit `Gemfile`, changing the line `gem 'rails', '3.2.6'` to gem `'rails', '3.2.8'`
2. Run `bundle update rails`

What about other Rails-generated entries in the `Gemfile`, such as `sass-rails`, `coffee-rails` and `uglifier`?
