Solution:
NEW FEATURES
 
1) Variance Cube: Variance Cube is a newly licensed feature designed to
   highlight incoherent data.  The effect of this is to make the faults and
   subtle stratigraphic features more pronounced.  Variance cube computes the
   squared difference from the mean value at a constant time. 

     . Variance Cube is for 3D only.

     . The parameters are Window length, Inline Range and Crossline Range.  
       The Inline and Crossline range are the number of traces to look in either
       direction.  A value of 3 would be the center trace and one trace on each
       side if the center for a total of 3 traces.  Using 3+3 would use 3 traces
       in the Inline direction and 3 traces in the Crossline direction.  3x3
       would use a square with 3 traces on a side.  Values of 3 and 5 generally
       yield reasonable results.  Larger values will tend to smear the data.
       The Window Length is used to reduce coherent signal.  Too large a window
       will smear the data and too short a window will leave coherent data.  The
       default parameters of 3x3 and 100 ms window generally yield good results. 
       Increasing the trace range perpendicular to the fault may highlight the
       fault slightly better.

2) Computed Seismic Attributes: Combo Attribute:  An "Export All to ASCII" 
   option has been added to the functionality of CSA.

    . This allows the user to export all of the CSA attributes to an ASCII file
      created in your home directory.
