To assure interoperability, the subscriber has to use dataset metadata for decoding with a major version that matches the major version in dataset messages sent by the publisher.
Removing fields from the dataset content, reordering fields, adding fields in between other fields or a data type change in fields results in an update of the major version.
If at least one property value of a dataset metadata field changes, the major version is updated.
There can be situations where older configurations of a publisher are loaded and changed with product specific configuration tools. In this case the major version is updated if the configuration tool is not able to verify if the change only extends the configuration and does not change the existing content.
