cnvgrib-1.0   - August 2003 - Original version

cnvgrib-1.0.1 - October 2003 - Corrected error converting level info for
                               "depth below land surface" from GRIB1 to GRIB2.
                             - Removed statement that set GRIB1 local table
                               version to "2".

cnvgrib-1.0.2 - May 2004 - Changed Master Table Version Number from 1 to the
                           current "operational" value of 2, when converting
                           from GRIB1 to GRIB2. 
                         - Added support for Gaussian grids.
                         - Few minor bug fixes relating to:
                            1) ensemble params 191 and 192 (grib1 table ver 2)
                            2) negative pv surface values
                            3) radius of earth
                            4) # of missing values in PDS/PDT

cnvgrib-1.1.0 - January 2005 - WMO approved the JPEG2000 and PNG Data 
                               Representation Templates ( 5.40000 and 5.40010,
                               respectively ) for operational use.  The 
                               templates were assigned WMO values of 5.40 and 
                               5.41, respectively.  Changes were made to the 
                               source and to acceptable program options to 
                               recognize either template number.
                             - Added new option "-m" to support encoding of 
                               "Missing" data values within the data field when
                               using Data Representation Templates 5.2 
                               (option -p2) and 5.3 (options -p31 and -p32 ).
                               Missing value management is an alternative to
                               encoding a bitmap when using DRTs 5.2 and 5.3.
                             - Fixed bug passing null pointers to routines
                               expecting a valid target.  Thanks to Jaakko
                               Hyvatti and Portland Group.
                             - Added fix for bug that caused seg faults on some
                               systems when generating GRIB1 messages.  Thanks 
                               to Robert Shectman for this one.

cnvgrib-1.1.1 - April 2005 - Corrected the scaling factor used when converting
                             potential vorticity surface values.

cnvgrib-1.1.2 - January 2006
			- Added a new option "-nv" to cause vector quantities 
			  to be stored in individual GRIB messages versus
       			  being bundled together which is the default.

                          and pngpack.f) with double precision to fix for bug
                          that caused seg fault on NAM tile files
                        - Added a check for the length of KPDS to determine
                          the grib is ensemble.
                        - Added new level (Nominal top of the Atmosphere

                          Note: Valid only with complex packing:
                           1. Complex packing
                           2. Complex packing and spatial differencing
