Error code IGE_REC_SCANSOFT_ERROR and warning code IGW_REC_SCANSOFT_WARNING have been replaced with IGE_REC_EXTENDED_ERROR and IGW_REC_EXTENDED_WARNING, respectively. If such an error or warning is returned by a Recognition API function, an extended error code and a detailed description can be obtained from the ImageGear error record.

API functions that iterate through some internal lists, such as IG_REC_output_format_next_get, now return an IGW_LAST_ITEM_REACHED warning when they reach the last item in the list. In v16 they returned IGW_REC_SCANSOFT_WARNING in such a case.
