+	* Changes: Changes for release 2.3 - see Changes file to get to know about
+	  the version numbers of this software.
+
+2011-05-10	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Added a column which tells
+	  if a river counts its km up or downwards.
+	  To update existing databases:
+
+	    ALTER TABLE rivers ADD COLUMN km_up BOOLEAN NOT NULL DEFAULT true;
+
+	* src/main/java/de/intevation/flys/model/River.java:
+	  Adjust Hibernate mapping of new column.
+
+2011-05-10	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
+	  Fixed flys/issue11 and flys51.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  Add some unsharp comparison (eps = 1e-6) to avoid 
+	  numerical problems.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Removed. Not need any longer.
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Use unsharp lookup.
+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Flush more often. Hopefully this reduces hibernate sync
+	  problems?!
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Fixed silly bug. Set flush mode back to auto because
+	  manual flushing causes some undetermined problems.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Do not load _all_ values from discharge tables and
+	  wst columns. This is extremly slow and will lead
+	  to OOM if more rivers are imported. Now only the
+	  last 20 columns und discharge tables are cached.
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  New. Key for caching discharge table values and wst
+	  column values.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Fixed bug in equals().
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Removed too eloquent debug output.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Use BigDecimals as representation for the numeric components
+	  which prevents running into unique constraint problems
+	  caused by imprecision.
+
+	* src/main/java/de/intevation/flys/importer/ImportRange.java,
+	  src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Ranges are now cached globally, too.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Improved logging.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
+	  Removed superfluous imports.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/StaFileParser.java:
+	  Only accept main value types 'Q', 'W', 'D' and 'T' by default.
+	  '-' is not handled any more because it causes too much constraint
+	  problems. You can overwrite the imported type with the
+	  system property flys.backend.main.value.types" (default "QWTD")
+	  
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Set session flush mode to manual. Hopefully this improves the
+	  performance a bit.
+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java,
+	  src/main/java/de/intevation/flys/importer/ImportGauge.java,
+	  src/main/java/de/intevation/flys/importer/ImportWstColumn.java,
+	  src/main/java/de/intevation/flys/importer/ImportRange.java,
+	  src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
+	  Improved logging.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstColumnValueKey.java: Deleted
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java: Reinserted
+	  here in a more generalized form.
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Cache the discharge table value, too.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
+	  Use the global cache.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  New. Centralized caching in the thread local context. Importing
+	  the Elbe leads to OOM because the column values of the
+	  WST files where loaded separately for every file.
+
+	* src/main/java/de/intevation/flys/importer/ImportPosition.java,
+	  src/main/java/de/intevation/flys/importer/Importer.java,
+	  src/main/java/de/intevation/flys/importer/ImportAnnotation.java,

+	  src/main/java/de/intevation/flys/importer/ImportAttribute.java,
+	  src/main/java/de/intevation/flys/importer/ImportTimeInterval.java:
+	  Adjusted to use the new global context.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Dropped constraint which
+	  forces discharge tables to have a unique time interval
+	  for a given gauge and kind.
+
+	  There are AT files (historical Mosel/Perl/Perl/1967-1981.at
+	  and Mosel/Perl/1967-1981-1.at) which violate this
+	  constraint. Its a technical question to the customer
+	  how to handle these cases.
+
+	  To adjust existing databases:
+
+	    ALTER TABLE discharge_tables DROP CONSTRAINT discharge_tables_gauge_id_key;
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstParser.java:
+	  There are wst files where column names are not unique.
+	  Make them unique by appending (1), (2) and so on.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Import the "HW-Schutzanlagen", too.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Make import of historical discharge tables work.
+
+	* doc/schema/postgresql.sql: Added forgotten column 'description'.
+
+	  !!! You have to drop your database !!!
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
+	  src/main/java/de/intevation/flys/model/DischargeTable.java:
+	  Add the forgotten description property.
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
+	  Fixed problems with date recognition.
+
+	* src/main/java/de/intevation/flys/importer/ImportGauge.java:
+	  Prefix the description of the historical discharge tables 
+	  with "Histor.Abflusstafeln".

+	  Fixed silly programming error.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
+	  Inject 'kind' attribute.
+
+	* src/main/java/de/intevation/flys/importer/ImportGauge.java:
+	  Traverse the "Histor.Abflusstafeln" for the historical
+	  discharge tables. too. TODO: Store them in the database.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
+	  Added convinience constructor to set the kind of the
+	  discharge table.
+	  
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Prefix "Zusätzliche Längsschnitte" with "Zus.Längsschnitte"
+	  in description.

+
+	* src/main/java/de/intevation/flys/importer/ImportTimeInterval.java:
+	  New. Importer model help fetching the database peer.
+
+	* src/main/java/de/intevation/flys/model/TimeInterval.java:
+	  Add convinience constructor with start and stop time.
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
+	  Attach a time interval to a discharge table if we find one.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
+	  Store the reference to the importer model of the 
+	  time interval of the discharge table.
+
+2011-05-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:

+
+	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Parse the "zusaetzliche Laengsschnitte", too.
+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java:
+	  Add getter/setter for column 'kind'.
+
+2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstParser.java:
+	  Fixed flys/issue19: Do not take km column in wst file as a water level.

+
+2011-05-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstParser.java:
+	  Removed superfluous import.
+
+2011-04-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstColumnValueKey.java:
+	  New. This class is used as distinct key of a WstColumnValue - e.g. as
+	  key in a map.
+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java: A
+	  WstColumnValue cache is build up while initialization. This cache
+	  contains all WstColumnValues that exist in the database.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java: New
+	  constructor that takes the WstColumnValues cache. It is used to
+	  initialize new ImportWstColumnValue objects.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumnValue.java:
+	  Speedup: A ImportWstColumnValue has a WstColumnValues cache that
+	  contains all WstColumnValues existing in the database. This makes it
+	  unnecessary to call an sql statement for each WstColumnValue to
+	  determine its existence in the database.
+
+2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql, doc/schema/postgresql-cleanup.sql:
+	  Added a view 'wst_value_table' which aggregates the data
+	  to build w/q value tables.
+
+	  To update existing databases:
+
+	  BEGIN;
+	    CREATE VIEW wst_value_table AS
+	        SELECT wcv.position AS position,
+	               w,
+	               (SELECT q

+	                         ON wcqr.wst_q_range_id = wqr.id
+	                       JOIN ranges r
+	                         ON r.id = wqr.range_id
+	                WHERE  wcqr.wst_column_id = wc.id
+	                       AND wcv.position BETWEEN r.a AND r.b) AS q,
+	               wc.position                                   AS column_pos,
+	               w.id                                          AS wst_id
+	        FROM   wst_column_values wcv
+	               JOIN wst_columns wc
+	                 ON wcv.wst_column_id = wc.id
+	               JOIN wsts w
+	                 ON wc.wst_id = w.id
+	        ORDER  BY wcv.position ASC,
+	              wc.position DESC;
+	  COMMIT;
+
+2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/Wst.java:
+	  Add forgotten one to many relation Wst -> WstColumn.
+
+2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java,
+	  src/main/java/de/intevation/flys/importer/WstParser.java:
+	  Import of q ranges of wst files was totally broken. :-/
+	  You have to reimport all your data.
+
+2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:

+	  point of the river.
+
+2011-04-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Added 'position' column to wst_columns
+	  to allow order them by there column position in the original
+	  wst file.
+	
+	  Update existing database with:
+
+	    BEGIN;
+	      ALTER TABLE wst_columns ADD COLUMN position int;
+	      UPDATE wst_columns w SET 
+	        position = id - (SELECT min(id) FROM wst_columns WHERE wst_id = w.wst_id);
+	      ALTER TABLE wst_columns ADD CONSTRAINT wst_columns_wst_id_position_key
+	        UNIQUE (wst_id, position);
+	    COMMIT;
+
+	* src/main/java/de/intevation/flys/model/Wst.java,

+
+2011-04-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Added new column 'kind' in
+	  discharge tables and wst to distinguish between different
+	  kinds like 'Haupt-WST', 'zusaetzliche Laengsschnitte',
+	  'amtliche Daten' and so on.
+
+	  Update existing databases with:
+	    BEGIN;
+	      ALTER TABLE discharge_tables ADD COLUMN kind int NOT NULL DEFAULT 0;
+	      ALTER TABLE wsts             ADD COLUMN kind int NOT NULL DEFAULT 0;
+	    COMMIT;
+

+
+2011-03-30  Ingo Weinzierl <ingo@intevation.de>
+
+	Tagged RELEASE 0.1
+
+2011-03-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/Range.java:
+	  Forgot to save the last change before commit.
+
+2011-03-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/Range.java:
+	  Added methods to find out if two ranges intersects.
+
+2011-03-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/Gauge.java:
+	  Added an one to many relation to the discharge tables of a gauge.
+
+2011-03-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Finished import of WSTs.
+
+	TODO 1: Speed it up! It takes on a high end machine over 7(!)
+	        minutes only for the data of the Saar.
+	TODO 2: Double precision floating point representations produced
+	        by the the parsers leed to unique constraint violations
+			in the backend on a second run. So the import is currently
+			only working on freshly initialized data bases.
+			More consequent working with BigDecimal and some
+			rounding may be of help here.
+
+	* src/main/java/de/intevation/flys/model/WstColumnValue.java:
+	  Added convinience constructors.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumnValue.java:
+	  Added getPeer() method.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Add a list of the ImportWstColumnValues produced by the WST parser.
+
+	* src/main/java/de/intevation/flys/importer/WstParser.java: Add
+	  the (km, w) values to the ImportWstColumns.
