Field Change Summary

Any change with respect to whitespace is ignored. "Minor" changes are text changes that only affect capitalization and punctuation. Most other changes are marked as "Major." Simple schema changes are treated as Minor, such as the change from AffectedResource to Affected_Resource in Draft 8, or the relationship name change from "IsRequiredBy" to "RequiredBy" in Version 1.0. For each mutual relationship between nodes A and B (such as ParentOf and ChildOf), a relationship change is noted for both A and B.

Relationship Changes

The "Version 2.7 Total" lists the total number of relationships in Version 2.7. The "Shared" value is the total number of relationships in entries that were in both Version 2.7 and Version 2.6. The "New" value is the total number of relationships involving entries that did not exist in Version 2.6. Thus, the total number of relationships in Version 2.7 would combine stats from Shared entries and New entries.
