title: Should I learn Spring 2 or 3?
body: <p><a href="http://www.springsource.org/" rel="nofollow noreferrer">Spring Framework</a> 3 seems to be right around the corner, but the GA version is 2.5.6. </p>
  
  <p>If this is the first time I'm approaching the subject, should I start with the stable version, or should I start with the new version and save myself migration issues?</p>
  
  <p>How different is version 3 from version 2? How near is Spring 3?</p>
