Experimental caching of datacage recommendations. The respective hook is called a lot and running the datacage over and over again when loading data can be expensive. So the generated recommendations are cached for some time. Hopefully this improves the overall speed of loading data from the datacage.

2011-09-19      RELEASE 2.5

    NEW:

        * Improved the data model to support:
          - cross sections
          - hyks ("Hydraulische Kenngroessen")

        * Improved the importer to read:
          - PRF files
          - HYK files

        * Added a central Config to configure the Importer. There are several
          system properties to adjust what to import (see ChangeLog for
          details).

        * Added a Postgis and Oracle models for spatial flys data:
          - catchments
          - river axes
          - buildings
          - fixpoints
          - cross section tracks
          - hws ("HW-Schutzanlagen")
          - floodplains

        * Bumped Hibernate up to 3.6.5.

        * Bumped Apache DBCP up to 1.4.



2011-06-27      RELEASE 2.4

    New:

        * Improved the data model to support:
          - edges ("Oberkante", "Unterkante")
          - annotations

        * Improved the importer to read:
          - edges
          - annotations

        * Made search for gauges in River independent of from/to
          kilometer order.


    Fixes:

        * flys/issue76 Close gaps between q ranges

        * flys/issue110 Fixed import of ATs that skipped the first value.



2011-05-13      RELEASE 2.3

    New:

        * Import of:
          - "zusätzliche Längsschnitte"
          - "Fixierungen"
          - "amtliche Linien"
          - "Hochwassermarken"
          - "Historische Abflusskurven"
          - "HW-Schutzanlagen"

        * Improvements in the SQL schema:
          - Added a 'kind' column to WSTs
          - Added a 'position' column to WST columns to enable sorting WST columns.
          - Added a 'km_up' column to rivers to determine the flow direction of rivers.

        * Rivers are now able to:
          - determine their min/max kilometer range
          - determine the selected gauge(s) based on a kilometer range

        * WSTs are able to determine their min/max Q range.

        * Gauges are able to determine their min/max W range.

        * Added a view 'wst_value_table' that aggregates the data to build w/q
          value tables.

        * Added one-to-many relation Wst -> WstColumn

        * Speedup of the importer by using an internal caching mechanism.

        * Sta-Parse just accepts the following main value types: 'Q', 'W', 'D' and 'T'


    Fixes:

        * Fixed import of Q ranges in wst files.

        * Fixed flys/issue19: Do not take km column in wst file as a water level.

        * Fixed flys/issue11 (Diagramm: Fehlerhafte Werte in Abflusskurven)

        * Fixed flys/issue51 (WINFO: Fachdaten am Pegel Perl enthält Sprünge)


    !!!

    The version number of this release depends on an existing desktop variant of
    this software that is in version 2.1.
