Too much has changed to list here. Major parts of the core of Callisto have been re-written. The most important changes are the replacement of Maverik by Ogre and the new GUI. The interface has also changed and some functions have been removed/added. The highlights are:
- introduction of labels by means of: CAL_CreateLabel, CAL_SetLabelCaption, CAL_SetLabelColor and CAL_DestroyLabel
- this means that the old definition of "label" (e.g. a name for an object/group) is now called "name"
- introduction of overlays to show user defined information on a fixed position on screen
