Hello evod,
yes you where right. the right-turning is possible as before, but now the right-turning is not a separated path anymore. When driving on Taborstraße coming from south-west, then there are two lanes. the left lane is marked "straight" (and then goes left into Nordbahnstraße), and the other lane goes right into Nordbahnstraße.
