"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.

Representation Templates 5.2 and 5.3 by adding
MDL/Glahn algorithm for determining effective
groupings.

were assigned WMO values of 5.40 and 5.41,
respectively. Changes were made to the source to
recognize either template number.

field with DRT 5.40 or 5.40000 (JPEG2000).

Arthur Taylor/MDL, used when unpacking Data
Templates 7.2 and 7.3.
- 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
encoded incorrectly.
- Added routine gdt2gds that converts grid information
from a GRIB2 Grid Description Section (GDS) and
Grid Definition Template to GRIB1 GDS info.

encoding algorithm on a grid with an insanely large
number of data points bitmapped out.
