+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
+	  Introduced a 'scale' parameter in the getValues() method.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Filled
+	  the out() operation with code that draws a discharge table of one or
+	  more gauges specified by the given range in entered in a previous state.
