+2010-06-30  RELEASE 1.1
+
+    NEW:
+
+        * Cache statistics are available as MBean using JConsole.
+
+        * Deactivated the caching of raster elements to improve performance.
+
+    DDED:
+
+        * A central Configuration instance that might be used to adjust settings
+          of the geo-backend.
+
+
+2010-04-28  RELEASE 1.0
+
+    NEW:
+
+        * Support for MultiLinestring and MultiPolygon detection retrieved by
+          the database.
+
+        * Spatial queries using LineStrings can be sent to the database.
+
+        * Sql-cache synchronization after database upates have taken place. A
+          thread is started in a specific time interval. Elements are removed
+          from cache if the sql-statement that has been used to retrieve these
+          elements contains a table that have been updated since the last 
+          synchronization. The time interval (in seconds) can be configured via 
+          system property 'caching.cleaner.interval' (e.g.
+          caching.cleaner.interval=600 for an interval of 10 minutes).
+
+    Added:
+
+        * JavaDoc documentation.
+
+
+2010-03-08  RELEASE 0.5
+
+
+2010-01-27  RELEASE 0.4
+
+    New:
+
+    * Experimental Cache for database queries and 
+    results of parameterisation: Database queries are 
+    transparent against cache.
+
+    * Support for raster data access to SDE via RasterObject
+
+    * Added interpolation for bilinear and bicubic 
+    spline interpolation on rasters
+
+    * Improved connection pooling for re-use of connections (#34)
+
+    * Improved memory consumption of SQL results produced by SDE by 
+    over 90% while removing redundancies for objects (especially 
+    date objects): e.g. from 256 MB per Interpolation to 15 MB. (#107)
+
+
+2009-12-17  RELEASE 0.3
+
+    New:
+
+    * !!!! Java6 is mandatory now! Older version are not supported any longer !!!
+    *  Added "point on polygon" spatial query support.
+
+    Fixed:
+
+    * Avoid index out of bounds exception in some case when accessing database
+    columns that are not provided by the database result set.
+
+
+2009-11-13  RELEASE 0.2
+
+    New:
+
+    * Added spatial query support for the first use cases. It uses OGC Simple Features for
+    SQL Syntax (SFS) to the inside and OGC WKT (Well Known Text) for
+    geometry respresentations
+
+    * Enhanced configuration to ArcSDE Backend in Pool-Mechanism for
+    fine-tuning interaction and pooling.
+
+    * Added support for INNERJOIN, ORDER BY and GROUP BY for spatial
+    queries (needs more testing)
+
+    * Support for gaps in temporal and spatial data added.
+
+    Improvements:
+
+    * Improved memory handling of Backend-results in geo-backend
+
+    * Stabilized binding to ArcSDE Backend (issue 34), 
+    https://roundup-intern.intevation.de/gnv/issue34
+
+         
+
+2009-10-07  RELEASE 0.1
+
+    New:
+
+    * Imported proto type database access layer.
+    * Made access layer look like java.sql.*
