What are Audit History entries of Type=Relation?

[dbl]

We are noticing new entries in the Audit History of a knowledge article of Type = Relation.

For example

Previously, there were only entries of Type=Audit shows old and new value.  

We did recently enable Table Rotation for sys_history_line that added relation fields to sys_history_line

sys_history_line000

sys_history_line001

sys_history_line002

sys_history_line003

Is this related?   I didn't find any WIKI articles on this so am posing the question here.

Did you ever figure this one out, jbl. I find myself wondering about the same thing.

Generally when a Relationship Record is removed for the Object, the Audit would show this kind of an entry.

For example, if you remove an User from a Group, in the Audit history, you will see a similar record.
