glib-1.0   - August 2003 - Original version

g2libc-1.0.1 - May 2004 - Changed the library name from "libg2c.a" to 
                          "libgrib2c.a" to avoid conflict with the g77 libg2c
                          library.
                        - Added support for Grid Definition Template 3.31,
                          Albers Equal Area.
                        - Changed most PDT templates in module pdstemplates to
                          allow negative surface values.
                        - Many minor changes to help get clean compiles.

g2libc-1.0.2 - December 2004 - 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 to
                             recognize either template number.
                           - Fixed bug encountered when packing a near constant
                             field with DRT 5.40 or 5.40000 (JPEG2000).
                           - Added consistency check, provided by 
                             Arthur Taylor/MDL, used when unpacking Data 
                             Templates 7.2 and 7.3.
                           - Added functionality to support encoding of
                             "Missing" data values within the data field when
                             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
                             groupings.

g2libc-1.0.3 - December 2005 - Two bug fixes:  1) Error encoding constant
                               data field.  2)  Error encoding grid with
                               large bitmap using DRT 5.40 - JPEG2000.

g2libc-1.0.5 - August   2007 - Added GDT 3.204  Curvilinear Orthogonal Grid

g2libc-1.1.7 - August   2008 - Added GDT 3.32768 Rot Lat/Lon E-grid (Arakawa)

g2libc-1.1.8 - January  2009 - Initialize variable lencsec2 in routine g2_unpack2.c
                               variable ndpts in routine g2_unpack7.c
                             - Changed the structure name template to gtemplate to avoid 
                               of reserved word in C++ 
                             - Change routine seekgb.c to use 4 bytes instead of sizeof(g2int)

g2libc-1.1.9 - June     2009 - Updated version jasper-1.900.1, libpng-1.2.35 and zlib-1.2.3
                             - Fixed bug causing seg fault when using PNG 1.2.35

g2libc-1.2.0 - March    2010 - Added PDT 4.31 Satellite Product
                             - Added PDT 4.15 WAFS Product

g2libc-1.2.1 - August   2010 - Added PDT 4.40,4.41,4.42,4.43 for Atmospheric Chemical Constituents
                             - Added GDT 3.32769 Rot Lat/Lon None E-grid (Arakawa)
                             - If section 2 has zero length, return IERR=0

g2libc-1.2.2 - March    2011 - Corrected PDT 4.42,4.43 for Atmospheric Chemical Constituents
