If the foreign key is not explicitly specified when defining a relationship, Eloquent will now use the table name and primary key name for the related model to build the foreign key.For the vast majority of applications, this is not a change of behavior.Previously, this would fall into the dynamic "where" clause builder and add a "where" clause for the "key" column.
