        * Support for MultiPolygons retrieved by database.

        * Support for MultiLinestrings retrieved by database.

        * Support for spatial queries using LineStrings.

        * Support for cache synchronization after database updates.

2010-03-08  RELEASE 0.5


2010-01-27  RELEASE 0.4

    * 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

    date objects): e.g. from 256 MB per Interpolation to 15 MB. (#107)

    * Experimental Cache for database queries and 
    results of parameterisation: Database queries are 
    transparent against cache.
