+	* doc/conf/conf.xml: Deactivated gauss filter because
+	  it blurs no data areas too.  Moreover gauss filtering does not 
+	  seem to be necessary at all. Possible TODO: Mask the no data
+	  areas while filtering.
+
+	* src/main/java/de/intevation/gnv/state/profile/verticalcrosssection/VerticalCrossSectionOutputState.java:
+	  Added generation of polygon data suitable for PolygonPlot.
+
+	* src/main/java/de/intevation/gnv/state/timeseries/TimeSeriesOutputState.java:
+	  Some hacks to display the new Chart. XXX: This class is
+	  a real mess ... but I've said that before.
+
+	* src/main/java/de/intevation/gnv/chart/Chart.java: Made it
+	  serializable.
+
+	* src/main/java/de/intevation/gnv/chart/VerticalCrossSectionChart.java:
+	  New. Chart for vertical cross sections. Mainly a copy of
+	  Ingo's prototype implementation. TODO: parameter based i18n.
+
+	* src/main/java/de/intevation/gnv/math/Interpolation3D.java: Code
+	  simplification. Made it Serializable to be cachable persistently.
+	
+	* src/main/java/de/intevation/gnv/math/AttributedXYColumns.java:
+	  Added fields for the interpolation and the generated PolygonDataset.
+	  Its used as the data carrying object in cache now.
+
+	* src/main/java/de/intevation/gnv/jfreechart/PolygonPlot.java:
+	  Removed println debug code.
+
+	* src/main/java/de/intevation/gnv/jfreechart/PolygonRenderer.java:
+	  Added a little hack to draw the polygons of the interpolation.
+	  The values are in y-direction all below zero (depth is given
+	  by negative values) so the drawing is mirrored along y axis.
+	  This special behavior is determined by the position of data 
+	  bounding box. At first I suspected a ccw issue here but some
+	  initial tests falsified this hypothesis. We need to have a
+	  deeper look at this but till than it works.
+
+	* ChangeLog: Fixed some typos.
