title: Single Page Backbone App Notification when code version changes
body: <p>I have a single page backbone app that is served by a stack using ruby on rails.  My issue is that if there is a code change in production, the users will not receive the new code until they refresh.  I would like to provide a way of letting the user know when they need to refresh.  Can any of you provide suggestions, or methods you tried in the past?</p>
