+
+	* doc/conf/artifacts/minfo.xml: Added states and transitions for MINFO
+	  middle bed height calculation.
+
+	* src/main/java/de/intevation/flys/artifacts/states/MultiStringArrayState.java:
+	  New. Nearly a copy of MultiIntArrayState but uses String values.
+
+	* src/main/java/de/intevation/flys/artifacts/states/SoundingsSelect.java:
+	  New subclass of MultiStringArrayState. It will be used for bed heights
+	  selection. We need to do handle the values as string, because singles
+	  and epochs are mixed, so the DB ID is not enough as parameter value.
+
+	* src/main/java/de/intevation/flys/artifacts/states/MiddleBedHeight.java:
+	  New. This state will trigger the calculation for middle bed height in
+	  MINFO module.
