title: What extra features does FB 4.5 offer over FB 4?
body: <p>I am considering upgrading my copy of Flash Builder to 4.5, and would like a list of the new features in the new version before I commit. I have heard that the ASUnit tests integrate better than previously, and that there are some nice features like quick fixes, is there anything else? </p>
  
  <p>Finally, based on your experiences using it, are there any shortcomings to look out for / avoid?</p>
