Since version 2.28.0, ecCodes has changed the way it encodes certain GRIB2 parameters, in preparation for our Migration to GRIB edition 2. The complete list can be found in Migration to GRIB2 - new in ecCodes . If you encode those particular GRIB 2 GRIB2 fields with ecCodes 2.28 or newer, you will not be able to decode them properly with an older ecCodes. We strongly recommend to make sure all your production chain uses an up-to-date ecCodes version for better results.
