Changes

3.68 You can now use targets defined before the last object that is displayed in an assignment. Make sure all objects the user must not use are secondary targets (shift key).
Some improvements in the property dialogs (e.g. area of polygons).
Some small changes in number display in property dialogs.
3.67 Removed some small bugs. Russian translation was missing.
3.66 It is now possible to change the description of objects.
One line icon bars may now contain all possible icons.
  Objects hidden by a condition can no longer be selected.

3.64 Midpoints now remember the types cross and diagonal cross.
3.63 Removed an error in start value for drawing of functions.
3.62 It is now possible to set the size of the selection area in multiples of the point size with a menu option. In applets, you have to add the parameter "selectionsize" by hand.
3.61 Code reorganized internally.
  It is now possible to refer to later defined objects in expressions, using the syntax @name or @"name". However, these expression will not work in macros.
  Objects can now be formatted under conditions. With the edit tool active, select the object with the Ctrl-key. In the dialog enter conditions for colors etc.
  If the coordinates of a point depend on the point itself, then the point can be moved. Thus the movement can be restricted.
  Fixed point referring to themselves are now loaded and saved with their current position.
3.6 Stable Version.
