Hi laz89,
Yes, labels were re-worked quite a bit for version 19. The behavior you are after can easily be set in the Info Box using the Geometry Method button. It is the second button to the right of the layer pulldown menu. Toggle this to control the leader line placement method.
TIP: The first button to the right of the layer pulldown menu is another Geometry Method option that controls whether a label is Associative or not. If a label is associative and you delete the element it is associated with, the label will be deleted also. To convert an associative label to be non-associative, select it, right-click and choose "Convert to Independent Label".
Best regards,
