Changes in Thuban 1.0.1
=======================

 - Updated translations

   Spanish and French by Daniel Calvelo Aros
   Hungarian by Norbert Solymosi.
   Brazillian Portuguese by Eduardo Patto Kanegae
   Russian by Alex Shevlakov
   German by Bernhard Herzog

 - Updated gns2shp extension.  Changes include a fix for RT#2453 

 - Thuban now remembers directories during a session.  E.g. if you open
   a shape file Thuban remembers the directory it was loaded from and
   the next time you open a shapefile the dialog will start in the same
   directory.  This also works for projections.

 - New experimental extension: svgexport

 - The PostGIS interface was improved substantially compared to 1.0.0.
   However, there are some limitations in Thuban's PostGIS support that
   can't be fixed in the 1.0.x series without introducing incompatible
   file format changes (one such limitation is the requirement for a
   column called "gid").

   The changes in more detail:
   
    - Added support for LINESTRING geometries 

    - Added some support for tables with an explicit SRID.

    - Thuban 1.0.0 used to allow tables with multiple geometry columns
      in some cases.  Those cases worked only by accident.  1.0.1 gives
      an error message when such tables are opened.  Real support for
      tables with multiple geometry columns is available in 1.1.x
      (currently only in CVS).

 - Fix a printing bug. The region of the map to be printed was a bit off
   so that some parts were not drawn sometimes. RT#2692

 - Other fixed issues:
      
      RT#2237 EPSG projection with unsupported (by the dialog)
              parameters causes exception
      RT#2239 (only the session tree part)
      RT#2245 Thuban don't start, unhandled exception
      RT#2482 (partly) NameError: name 'wx' is not defined
      RT#2549 exception when trying to generate one class



Changes in Thuban 1.0.0 (2003-12-23)
====================================

 - Updated translations:

   Italian by Maurizio Napolitano
   Spanish and French by Daniel Calvelo Aros
   Russian by Alex Shevlakov

 - some minor bug fixes


Changes in Thuban 1.0rc1
========================

 - Redering improvements

   Rendering the map in the main window does not freeze Thuban
   completely anymore. While the rendering occurs the window is updated
   regularly to show the progress and you can interact with the window
   and thuban in general even when the rendering is not complete yet

   The map display is also faster in many cases now, especially when
   doing classifictions.

   The renderes have a mechanism to define how new layer classes defined
   in extensions can be rendered (see the new wms extension for an
   example)

 - Added a few extensions in the Extensions sub-directory. Most of them
   are experimental to varying extents. Note that the binary packages
   might not contain all of these extensions.

   - gns2shp

     Convert GNS (GEOnet Names Server) files to shapefiles. See
     Extensions/gns2shp/gns2shp.py for more information

   - wms

     Use thuban as WMS client. See Extensions/wms/wms.py for more
     information

   - importAPR

     Import a ArcView project file (.apr) and convert it to Thuban.

   - profiling

     For developers: perfomance measurement for the rendering code.
     See Extensions/profiling/profiling.py for details.

   - drawshape

     This is a *very experimental* and potentially *dangerous* extension
     to add shapes to a shapefile. Be careful with it as it may lead to
     data loss. For more information, see Extensions/drawshape/README

 - A new command line option --enable-attribute-editing, which when
   given turns on editing of attribute values in the identify view. It
   only works on layers whose attribute data is stored in DBF files.
   This experimental and may lead to data loss, so be careful when using
   it.

 - EPSG projections

   Thuban now comes with two .proj files containing EPSG projections
   (epsg.proj and epsg-deprecated.proj in Resources/Projections/). These
   projections can be shown in the dialog with the new check boxes under
   "Show EPSG".

 - Context menu in the legend window

   The legend window now has a context menu for most of the layer
   commands

 - Localization updates

   The localization is now done with wxWindow's localization support and
   thus deals automatically with character encoding transformations and
   the standard dialogs are also translated properly if the wxWindows
   .mo files are installed

   Updated translations for French and Spanish contributed by Daniel
   Calvelo. Updated German translation

 - PostGIS improvements

   - Quote table and columns names properly.

   - The dialog deals better with duplicate connections (e.g. trying to
     create a new connection when there already is a connection for the
     same database)

 - Files written with the Windows version of Thuban can now be read by
   the unix version. The other way round was already possible.

 - The shapefile handling code now uses shapelib 1.2.10

 - Thuban should work without problems and warnings with Python 2.3 now.


Changes in Thuban 0.9
=====================

 - An initial version of the Thuban User's Manual. Currently only the
   XML sources and the images are shipped with the Thuban sources. The
   binary distributions do not contain the document at this point. An
   online version is available at
   http://thuban.intevation.org/documentation.html

 - New Translations: German, Italian and Russian. The Italian and
   Russion translations are based on 0.8.1 and therefore not quite up to
   date. German is up to date, though. For 1.0 we intend to have a
   translation period where all translations can be brought up to date.

 - PostGIS support. This feaure is still a bit experimental at this
   point and is not very well tested yet. It should work PostgreSQL
   7.2.1 and postgis 0.7 as that's what we tested it with. Newer
   versions probably also work.

   The user as which the connection is established obviously needs
   select permissions on any table to show and also on the
   geometry_columns table.

   Known Issues:

    - Only four geometry types are currently supported: POINT,
      MULTILINESTRING, POLYGON and MULTIPOLYGON.

    - Tables must have a gid column which is assumed to be a non-NULL
      integer which uniquely identifies the row.

    - It's not optimized so some things may be very slow. For instance
      the number of queries done could be reduced substantially
      especially if you use classifications. Having an index on the gid
      column can speed things up in that case. Note that at least older
      versions shp2pgsql do not create such an index.

 - Renamed the subdirectory extensions to libraries. The name extensions
   can now be used for a directory with Thuban extensions.


More changes in even more detail are listed in the ChangeLog file.
