Alfresco differences between version 3.2r and 3.3

[hydro]

Hi,

Can anybody tell me what's the difference between Alfresco version 3.2r and 3.3 ?
What new features did they add? and how do I enable these features.
I had recently installed version 3.3 on Windows OS and the basic outlook seems the same.
Any new changes? /enhancements?
