title: ie9-js - has something else rendered it obsolete?
body: <p>So, everyone knows ie9.js (from <a href="http://code.google.com/p/ie7-js/" rel="noreferrer">http://code.google.com/p/ie7-js/</a>). It seems to work, but it never left beta since the last release in 2010.</p>
  
  <p>Obviously, there are some other things that do something a bit similar (such as modernizr, html5shiv, and CSS3Pie), but they aren't quite the same (not least because they need to be applied per-feature or are more limited in scope).</p>
  
  <p>Is it still considered good practice to use it for modernisation? Should I be using something else?</p>
