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.*
