• Ver 3.1 (19 Dec 2005)
  - Allows locking restlength of links so that changing length in design mode can set up pre-animation stresses in links
  - Modified information displays to include more information
  - Allows zero length links
  - Added statusbar panel to display totaltime

  - Added wind and viscosity global settings
  - Revised settings on several global/node/link dropdowns
  - Improved mathematics of mode motion
  - Added new models in the distrbiution
  

• Ver 2.1 (2 Dec 2005)
  - Global settings now saved in model files
  - Added gravity property to nodes
  - Added ability to enter custom values for settings

  - Nodes will now bounce off the ceiling
  - Added option to include current model as part of email to author (paste from clipboard)
  - Added option to compact a model (remove unused links and nodes)
  - Display area now saved in model and restored when file is read (display area adjusted to minimum of model size)
