Background information:

1. I have JavaScript that makes an AJAX request.
2. I am using a version URL parameter to make sure that when a page loads it gets the latest version of the JavaScript file: `/path/to/file.js?v=20160511`

That problem I need to solve now is when I make a change to the data that is returned by the AJAX call (I assume this is considered an API break), and the JavaScript file (client). My first thought would be to somehow force the user to reload the page when I release a change to the API. What is a good process to make sure the client and server stay in sync?
