It used to be that a manytomany relationship could be assigned to None, which would be the same as calling clear().
E.g. obj.manytomanyrel = None was the same as obj.manytomanyrel.clear().
I think this was also in the documentation.
Now I cant do obj.manytomanyrel = None. I can however do this, obj.manytomanyrel = .
I think needs to be added to db-api and BackwardsIncompatibleChanges.
