+
+	Fix masterartifact in collections in cases where the original
+	masterartifacts facets do not come first in certain list. Query
+	'backend'/db instead.
+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java:
+	  (addSubtitles): Overridden, the master artifact has no range.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Set 'real' master artifact, defined to be oldest belonging to this
+	  collection.
