Please note:

GRIB2 templates 4.51 and 4.91 had the keys "codeFigure" and "categoryType" in the wrong order (See ECC-1797).
This has been corrected to be in line with WMO Manual on Codes. We apologise for any inconvenience caused.

Please note: There is a new webpage for the Migration to GRIB2: Migration to GRIB2
This webpage also includes a section where changes in the parameter encodings for the coming ecCodes versions are documented: Changes in the parameter encodings
