   + wms: experimental migrated to owslib 0.3 (Didrik Pinte)


Changes up to Thuban 1.2.1 (released 2008-02-03)
===========================
 - Rendering: Thuban's accelerated shapefile renderer is now 
   robust against shapefiles which contain empty shapes.

 - Text Encoding: Progress to make Thuban run better with different encodings
   and locales.  (Bernhard Reiter)

   + The class generator selector will work even in other languages.
     (Reported by Samuel Mesa)
   + Layer titles from filenames are saved in the correct encoding, so
     strings can be assembled from them, e.g. for the Layer Projection dialog.
     (Reported by Samuel Mesa)
   + Fixed [#586] (projection exception when changing projection) 
     (Reported by Stefanie Gunkel)

 - PostGIS support: Migrated from psycopg1 to psycopg2 (Didrik Pinte)
   Now UTF8 environments are better supported.

 - Windows packaging improved. Also it got easier to make a windows package
   that inclused everything. (Didrik Pinte)

 - move to wxPython 2.6 completed (Didrik Pinte)

 - Using the alpha channel for displaying raster images all the time.
   There is no selection possibility anymore for "masktype". (Bernhard Reiter)

   INCOMPATIBLE with Thuban 1.1 (development series) and 1.2.0:
   Ignoring the saved masktype in .thuban files, using "alpha" in all cases.
   With wx2.6 there is no need for other mask types anymore. Doing this
   change fixes a problem on the windows platform, where masktype=bit did
   not work so far.

 - Translation updates
   + Extensions are now localised as well (Bernhard Reiter)
   + German (Bernhard Reiter)
   + French (Didrik Pinte, Daniel Calvelo)
   + Spanish (Daniel Calvelo)
   + (New) Czech (Jachym Cepicky)

 - Problem fixes:

   + Fixed [#403] "can not add raster layer". Adds the ability to open more 
     then one raster file from one open dialog by multiple selection.
     Thanks to Jachym Cepicky and Bernhard Herzog. (Bernhard Reiter)

   + Printing reenabled under some platforms. (Bernhard Reiter)

 - Extensions (all Bernhard Reiter)

   + ogr: Some fixes to make it work with encodings and database connections.

   + wms: Some attemps to revive, but found out that PyOGClib is abandoned
     and does not work anymore. Needs work.

   + Extensions are now all under the menu entry with the same name,
     their maturity will be indicated by leading string in the menu text. 

   + New installation wide configuration file thuban_cfg.py which by
     default tries to import all interesting Extensions coming with Thuban.


Changes up to Thuban 1.2.0 (released 2007-03-13)
==========================

 - Python versions >= 2.4 call C extension modules with the locale set.
   This means those modules need to be robust against a locale
   where LC_NUMERIC is set in a way that the decimal_point might
   be a comma or something else. Problems are diagnosed 
   at least with shapelib, proj and gdal. To cope with it we:

   + Added a new option --setdecimalcommalocale to runtests.py so that
   all tests can be checked with a comma as  decimal_point, if we
   can find such an LC_NUMERIC. We only try a few in test/localessupport.py.

   + Fixed behaviour with proj by switching to LC_NUMERIC "C" before
   initialising the projection and afterward switch back.

   + Added a workaround to internal shapelib and pyshapelib.
   (Bernhard Reiter)

 - Startup improved: We fail right away if the internal encoding could
   not be determined. In this case, try to set the LANGUAGE variable to
   one value and use no colon.
   If we startup you can see the internal encoding in the about dialog now.
   (Bernhard Reiter)

 - Support for pysqlite2. (Didrik Pinte)

 - Added packaging directory, which already has an example how
   to load all extensions on windows. (Didrik Pinte)

 - Updated code to support new style wxPython 2.6 imports. So
   you need at least wxPython 2.6 . (Didrik Pinte)

 - New Classification "Pattern": Classify text attributes by regexp. 
   (Frank Koormann)

 - New or Improved Extensions:

    + Improved svxexport extension 1.0.1 (Bernhard Reiter)

	* Fixed ARC layer writing: No filling is done.
	You could actually get polylines with filling in between,
	when the classification for the lines had a fill color.
	E.g. this happens when you generate a classification from a ramp.

	* Fixed label export.

    + New export_shapefile extension (Jan-Oliver Wagner)
      Available from the experimental menu.

 	

Changes in Thuban 1.1.0
=======================

 - Thuban rembers directories in file selection dialogs during a thuban
   session

 - Add some support for wxPython 2.5 and 2.6.  Thuban is still
   compatible with wxPython 2.4.

 - Change the way thuban deals with non-ascii text.  The internal
   representation is now the user's default encoding.  Thuban works a
   bit better with a unicode build of wxPython but there are still
   problems.  (Bernhard Herzog)

 - Various raster data improvements.  Among other things, translucent
   images are now supported on a sufficiently recent wxWidgets (2.6).
   Also, only the part of the window actually covered by the image is
   drawn.  (Jonathan Coles)

 - Improved PostGIS support (Bernhard Herzog):

    - support tables with multiple geometry columns.  The user can
      select which one to use

    - support tables with srids

    - tables don't have to have a column named "gid" anymore.  The user
      can select the column to use for ids

    - PostgreSQL views are supported too

    - support LINESTRING geometries

    - support more PostgreSQL versions.  7.4 works now.

 - Added support for sizable points (Jan-Oliver Wagner)

 - When loading a (moved) session where shapefiles cannot be found, ask
   the user (Frank Koormann)

 - The middle mouse button can be used for panning now (Russell Nelson)

 - Give a warning when the projection selected for a layer is probably
   wrong (Russell Nelson)

 - Updated shapelib

 - New or improved extensions:

    - A new extension which exports a map as SVG 
      (Markus Rechtien, Bernhard Reiter)

    - Improved WMS extension (Martin Schulze)

    - New Extension to dump bounding boxes of all shapes of the selected
      layer (Frank Koormann)

    - New extension: umn_mapserver (Jan Sch�

    - New extension: OGR (Nina H�er)

    - New Extension: mouseposition. Tool to collect mouse click positions
      (map coordinates) in a dialog.  (Frank Koormann)

 - Documentation:

    - Add some documentation of the internals of Thuban.
      See Doc/technotes/

    - The thuban manual has been partly translated to German 
      (Jan-Oliver Wagner)

 - Updated translations: 
       Russian (Alex Shevlakov)

 - New translations:
       Brazilian Portuguese (Eduardo Patto Kanegae)xb
       Hungarian (Norbert Solymosi)


Changes in Thuban 1.0.0
=======================

 - 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.
