Apart from the changes listed below, this version includes functionality to send some anonymous information (Greenfoot version, Java version, Operating System, interface language etc) to the Greenfoot maintainers, to help with development planning. This can be disabled by adding a "greenfoot.uid=private" setting to your greenfoot.properties file. (comment added 15. July 2009)

• Greenfoot project files can now be associated with the Greenfoot application, so that you can open a scenario by double clicking the scenario's greenfoot.project file.

  • Added GreenfootImage.setTransparency() and GreenfootImage.getTransparency().
  • Added callback methods to detect when execution is started and stopped: World.started() and World.stopped().
  • Made Greenfoot case sensitive when dealing with names of sound and image files.
  • Most intesection tests now correctly use the rotated bounding box of actors.
