title: Upgrading from Groovy 1.3.5 to 1.7.5
body: <p>I've just inherited an application written in Groovy (version 1.3.5) and would like to upgrade it to the newest release (version 1.7.5).  </p>
  
  <p>I can't seem to find a reference that enumerates the differences in syntax, etc., which I would need to be aware of ... and yes, I looked at <a href="http://groovy.codehaus.org" rel="nofollow">http://groovy.codehaus.org</a></p>
  
  <p>Does anyone know of a good place that lists version changes?  </p>
  
  <p>Many thanks, </p>
