 Qt Jambi Library
************************************************************************

 - Made QTreeModel correctly update its internal cache when dataChanged
   is emitted.
   
 - Fixed missing exception message when exceptions are caused by native
   binding layer.
   
 - Made sure all classes that reimplement equals() also implement 
   hashCode() to honor contract in java.lang.Object that equal objects
   implies equal hash codes.
   
************************************************************************
 Qt Jambi Generator
************************************************************************
   
 - Made Generator automatically create a hashCode() reimplementation
   if equals() method is available and hashCode() is missing. 
   
 - Added new attribute to  and : "implements"
 
************************************************************************
 Eclipse Integration

 - Fixed crash on startup when widget box was open in the initial 
   workspace.
   
 - Fixed uncaught exception in custom widget selector when project 
   contains classes that have unresolved dependencies.

   juic builder is now only added automatically to new Qt Jambi 
   projects.
   
 - Added button in project properties that allow you to manually add 
   the juic builder to any project.
