- transportation nach class: Pfade/Tracks dünn+gestrichelt; Straßen weiß, Breite nach Klasse (motorway/trunk breit … minor schmal) — Pfade sehen nicht mehr wie Straßen aus - neue Label-Layer: poi (Kinderspielplatz/Schule… ab Z15) + housenumber (ab Z17), name:de - Label-Reihenfolge = Kollisions-Priorität (Orte zuerst)
