title: What is the difference between "Legacy Version" and "Stable Version"?
body: <p>I am using JQuery Mobile and there are two available versions: A stable version and a legacy version. I am not familiar with the latter one. </p>
  
  <p>What is a legacy version? or what is the difference with the stable version?</p>
  
  <p>Which one is recommended to use in a production site?</p>
  
  <p>Many thanks</p>
