  27 +The GPar class now handles special values for integer and floating point
  28 +parameters, such as INDEF, NONE, UNDEF, UNDEFINED (for an undefined value)
  29 +and INF, INFINITY, NAN (for values that are not a number). If presence
  30 +of these values can be checked using the isundefined() and the
  31 +isnotanumber() methods. An isvalid() method has been added to check also
  32 +if a parameter value is valid.

94 -None 101 +GNodeArray computations have been optimized in that the last interpolation
