* bump the version number to 0.7.1
* Work on the Cabri import filter, so that it actually becomes usable
  for some easier files..
* Improve the errors given by the "New Script Wizard", by making
  it get a proper error description from the python interpreter.
* Add a lot of documentation to the new classes.
* Fix the moving system again, it now only redraws exactly those
  objects that need to be redrawn.  E.g. when a constrained point was
  moved, before it was assumed that all of its parents, and their
  children would move, whereas in reality, a constrained point does
  not move the curve it is constrained to.  This is now taken into
  account for.  This much optimizes the case where we move the
  constrained point in examples/sine-curve.kig.
* Added a DESIGN document, documenting the Kig object system
  design.  I think that is rather finished now, and it's probably
  about time to try and make some other people than myself get it ;)
* Remove support for the ancient pre-0.4 file format that we still
  supported opening.  If you still have old files around using it, you
  should convert them to the new format, by opening them with a Kig
  version between 0.4 to 0.6, and re-saving them.  Maintaining
  compatibility with these old files doesn't seem very useful, because
  I don't think there are many files in this format available, and
  therefore I didn't think it was worth the trouble of porting the
  code to the new object system.
* Introduce a new file format that matches the new object system
  better.  Files in the old format can still be opened seamlessly.
* Add undo/redo support for changing visible aspects of an object
  ( size, color, shown state ).  In the new system, this was as easy
  as replacing the ObjectDrawer of an ObjectHolder with another one.
* Another ( hopefully the last ) major change to the object
  system.  Decouple the link between how an object is calced and how
  it is drawn.  We now have a hierarchy structure of ObjectCalcer's
  describing various objects and their interrelations.  On top of
  that, there are the ObjectHolder's, which hold a link to an
  ObjectCalcer from the hierarchy, and keep an ObjectDrawer describing
  how to draw it.  The document only keeps a list of ObjectHolder's,
  nothing else..

Maurizio, err, the changes that I think are relevant to you are:
1 improvements for the cabri file format filter
2 redesign of the classes, and a lot of work on documentation
3 improvement of the python scripting errors

Have fun with it ;)
cheers
