Version 2.20
Released December 02, 2005

   *  Import Michlet wave elevations
   *  Some hydrostatic properties are shown in the viewports, such as LCB, SAC, metacentric height etc. (mainparticuars must have been set)
   *  Mirror selected faces or layers
   *  Show Gaussian curvature of the surfaces in shading mode
   *  Resistance for yachts according to Delft Systematic Yacht Series
Bugs fixes or improvements:
   *  Rearranged the project settings dialog, it now has tabs for different data and settings
   *  Prevented the controlpoint-form to recieve focus while dragging a point, which caused the active
      viewport not to respond to mousewheel zooming after dragging a point
   *  Use escape key to quickly deselect all

   *  Ctrl-L shortcut opens layer dialog
   *  Output to DXF 3D-Polylines now also includes crease edges (knuckle lines)
   *  Optimized DXF output of linesplan a bit so that it does uses less line-segments for
      the crease edges as before. Data is now written as 2D polylines instead of 3D polylines
   *  Developed plates now written as 2D polylines instead of 3D polylines to a DXF file

Version 2.10
Released November 03, 2005

New features:
   *  Modified the design database to include a preview and improved search routine
   *  Show/hide layers in the linesplan
   *  Save a preview of the model in the file (used for browsing designs at the FREE!ship website)
   *  Choose in project settings if hydrostatic coefficients should be calculated using the dimensions
      from the project settings or the actual waterline dimensions
   *  Export files to Michlet

      mousebutton (or mousewheel) pressed
   *  KAPER resistance calculation for canoes and kayaks, according to John Winters
   *  Move points with arrow keys (not in perspective view). Increase/decrease stepsize by
      pressing + or -. Click the panel saying "Incr. distance" on the statusbar to manually set
      the distance.
   *  Added the following waterplane properties to the hydrostatics: waterplane area, coeff., LCF,
      entrance angle and Trv/long. moment of inertia
   *  Added metacentric height to hydrostatics
   *  Ctrl selecting of faces
   *  Added sectional area info to design hydrostatics
   *  Project selected points on a straight line segment

Bugs fixes or improvements:
   *  Fixed bug in offsets import from round bottomed hulls that ignored the metric/imperial
      settings in the file
   *  Prevent the program from zooming out on the model when undo is used
   *  When layers are turned on/off, viewports that have been zoomed in or out are simply redrawn,
      others viewports are zoomed out to the extents of the entire model
   *  Severe error occurring when an edge was collapsed with two faces attached with inconsistent
      normal directions
   *  Fixed locked points that where not scaled when the project units was changed to metric/imperal
      are correctly processed
   *  Corrected an error in the routine were imperial distances were translated into a text containing
      the number of feet and fractional inches. This error occurred when the value was negative but larger
      the -1.0 foot. In those cases the negative sign was omitted.

Version 2.0
Released October 06, 2005

   *  Added a database with FREE!ship designs to the website. These designs may be freely
      downloaded from www.freeship.org/designs Users willing to share their own designs are
      kindly invited to send their designs to [e-mail]

   *  Modified input-format of offsets of rounded hulls
   *  Implemented controlcurves as a new feature

   *  Switch visibility of partnames on or off in developed plates dialog
   *  Export all controlpoint coordinates to a textfile which can be imported in Rhino
   *  Modified the offsets output, also exports controlcurves
   *  The order of layers in the layer dialog can be modified. Also developed plates appear in the same
      order as the layers in the layer dialog
   *  View surface area, weight and COG from within the layer properties dialog
