title: Updating jQuery Version
body: <p>Just wondering if there's any tutorials or ways to update jQuery scripts and functions. </p>
  
  <p>I have version <code>1.4</code> and version <code>1.6.2</code> running, and I want to update both of them to <code>1.7.1</code> but I need to modify my script. I have no clue where to begin and what to change. Where can I start?</p>
