   A new feature: finding real and complex roots of polynomial
   equations with real coefficients (linear, square, cubic;
   also quartic in the registered version).

   Pressing the F1 key will now bring context-sensitive help in
   most of the dialog boxes.

   A major new feature: linear algebra operations (matrix and
   vector algebra, matrix inversion, systems of simultaneous
   linear equations).

   The editor for data buffer has been redesigned: it uses now
   a data grid.

   The maximum length of an expression has been increased to
   72 operands/operators or 120 characters (registered copies).

   column-wise data buffer computation if arithmetic errors
   occur at some of the points.
