title: Migrating to Django 1.4
body: <p>I'm currently developing a website in Django v1.2.7. That's the version as per requirements, but I think I could change it without problems. I was thinking about using v1.3 (because of class-based views, etc), but the version 1.4 was released a few weeks ago. My questions are:</p>
  
  <ul>
  <li><strong>Does it worth migrating to Django 1.4?</strong></li>
  <li><strong>What incompatibilities could I face when updating the version?</strong></li>
  </ul>
