Warning

The following functions have been removed:
grib_handle_new_from_template: This was already deprecated in GRIB-API and has been replaced by grib_handle_new_from_samples.
grib_context_new: This was experimental. One should use the default context


The following C function signatures have changed:
grib_get_data: no longer takes the final "size" argument. This was redundant and never used by the function.
grib_fieldset_new_from_files: The "where_string" and "order_by_string" arguments are now "const char*".
grib_handle_new_from_message: The "data" argument is now "const void*".
grib_handle_new_from_partial_message:  The "data" argument is now "const void*".


Warning

In the Fortran interface, for GRIB keys whose value is MISSING, GRIB-API returns -1 whereas ecCodes returns the constant CODES_MISSING_LONG.
It is best to check whether a GRIB key is missing by using the function "grib_is_missing" rather than comparing the result of grib_get with -1. See example here.

An example of such a key is "Ni" (the number of points per latitude) for Reduced Gaussian Grids. Please check your code and make sure you are not comparing with -1.
