On the 4.7 Drupal 7 Demo site I changed the middle letter of contact Kathleen Adams and it gets logged and becomes visible in the log tab. Then I make a change in the relationship tab, adding a Case Coordinator relationship to Megan Roberts and removing that relationship again. Both these changes to the contact are not logged.
Is there a setting that it will also log these changes? When there isn't such setting available, could this be considered a bug and reported as such?
The same questions for version 4.6.x because that is the LTS version I am using at the moment.
