The link in question doesn't work now.

@mpetazzoni i tried to replicate the behavior by setting up a minimal example. `mongoid-history` was not able to catch the changes in embedded documents. It basically works on the `parent_object.changes`...

@mpetazzoni i appreciate the research done on this bug. I will try to look into the cause.

Yes, @mateuspontes as i posted [here](https://github.com/mongoid/mongoid-history/issues/187#issuecomment-293155633), this is because the `changes` hash remains empty if we update only the embedded relations AND we are not using any code/gem to track...
