                         allow negative surface values.
                       - Added new routine to gridtemplates and pdstemplates 
                         modules to return number of entries in a specified 
                         template.
                       - Added New routines, getgb2p getgb2rp, used to request 
                         a packed GRIB2 message from a file.
                       - New module g2grids can be used to return GDT entries

                            using Data Representation Templates 5.2 
                            (complex packing) and 5.3 (complex packing and 
                            spatial differencing).  See octets 23 - 31 in DRTs
                            5.2 and 5.3 for more info on missing value
                            management.
                          - Increased the packing efficiency of Data 
                            Representation Templates 5.2 and 5.3 by adding 
                            MDL/Glahn algorithm for determining effective

                             respectively ) for operational use.  The templates
                             were assigned WMO values of 5.40 and 5.41, 
                             respectively.  Changes were made to the source to 
                             recognize either template number.
                           - Fixed bug encountered when packing a near constant
                             field with DRT 5.40 or 5.40000 (JPEG2000).

                           - Corrected the documentation for subroutine
                             addfield in the grib2.doc file.  Incorrect
                             arguments were specified for this routine.
                           - Corrected bug when packing Secondary missing
                             values in Data Representation Templates 5.2 and
                             5.3.

g2lib-1.0.6 - April 2005 - Modified the way GETGB2 manages the GRIB2 file 
                           indexes, so that it can be more efficient and
                           flexible when reading from multiple
                           GRIB2 files.
                         - Fixed bug in PUTGB2 that caused data fields to be

                           Grid Definition Template to GRIB1 GDS info.
