title: What functionality will I lose downgrading jQuery from 2.0 to 1.10?
body: <p>We are implementing a new website that will be used alongside an existing system. The current system uses IE8 but in setting up the new site, jQuery2.0 has been used.</p>
  
  <p>If we downgrade jQuery to 1.10, will we lose any of the functionality?</p>
  
  <p>The blog (<a href="http://blog.jquery.com/2013/07/03/jquery-1-10-2-and-2-0-3-released/">http://blog.jquery.com/2013/07/03/jquery-1-10-2-and-2-0-3-released/</a>) isn't very clear.</p>
  
  <p>Is this going to be a complex job to downgrade?</p>
