This week we released hotfixes for ecCodes/grib_api and EMOSLIB to add support for the GRIB2 packing scheme "Complex packing with spatial differencing" when there is no bitmap but missing values are coded in the data section (e.g. the most recent update of the NCEP GFS model). There are also other improvements in ecCodes: new installation options and a new MARS class.
These new versions are available on all ECMWF computer systems. If you encounter any issues please feel free to send feedback to Software.Support@ecmwf.int.
