Hi Folks: Just in time for the weekend. The MapServer developers are
pleased to announce the *official* release of version 4.0. Lot's of new
functionality, see the attached HISTORY.TXT file for the complete list.
The source code is available at:

  http://mapserver.gis.umn.edu/dload.html

Win32 binaries should be available shortly from both DMSolutions and
the University of Minnesota, as will a new version of the Itasca demo. A
new version of the MapServer documentation is also in the works. A good
summary of changes between 3.6.x and 4.0 can be found at:

  http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?MigrationGuide

Further announcements regarding the future of MapServer (new version
numbering, development roadmap, ...) will be made at a later date.

Anyway, enjoy!

MapServer Revision History
==========================

This is a human-readable revision history which will attempt to document
required changes for users to migrate from one version of MapServer to the
next.  Developers are strongly encouraged to document their changes and
their impacts on the users here.  (Please add the most recent changes to 
the top of the list.)

For a complete change history, please see the CVS log comments.  A copy of
the CVS logs is updated daily at the following URL:

Version 4.0 (2003-08-01)
------------------------

- Fixed problem with truncated expressions (bugs 242 and 340)

- Attempt at fixing GD vs libiconv dependency problems (bug 348)

- Fixed problem with invalid BoundingBox tag in WMS capabilities (bug 34)

- Fixed problems with SIZEUNITS not working properly (bug 373)

- Fixed MacOSX configure problems for linking php_mapscript (bug 208)

- Fixed problem with reference map marker symbol not showing up (bug 378)

- Use <Keywords> in WMS 1.0.0 capabilities instead of <KeywordList> (bug 129)

- One-to-one and one-to-many joins now work for Xbase files and are available
  to query templates. Low level one-to-one Xbase joins are available  via
  OGR.

Version 4.0-beta2 (2003-07-11)
------------------------------

- Added prototype of FastCGI support in mapserv_fcgi.c (not built by default).

- Report full error stack in the mapserv CGI and PHP MapScript (bug 346)

- Old index (.qix) format is deprecated (bug 273)

- Fixed problem with embedded legend and scalebar that would result in
  layers being added to the HTML legends (bug 171)

- Changed joins (XBase only at this point) over to the open-prepare-next...
  next-close way of doing things. Compiles fine, but needs more testing. 
  One-to-many support should work now but it needs to be hooked into the 
  template code yet.  Last thing before a candidate 4.0 release.

- Added ability to generate images in MapScript processQueryTemplate (bug 341)

- Added saving of output formats in msSaveMap()

- Fixed problem in PHP MapScript with variables that were not dereferenced
  before their values were changed by the MapScript wrappers (bug 323)

- Added support for Web Map Context 1.0.0

- Treat zero-length template values as NULL so that it's possible to
  set("template", "") from MapScript to make layer non-queryable (bug 338)

- Ditched the shapepath argument to the shapefileObj constructor

- CARTOLINE join style default changed to MS_CJC_NONE

- Tweaked code in legend builder to handle polygon layers slightly different.
  Now if a polygon layer contains only outlines and no fills (i.e. a polyline)
  then it is drawn using the zigzag legend shape rather than the box. I'll 
  add legend outlines back in shortly.

- Restored legend key outlines (triggered by setting OUTLINECOLOR). If an 
  outline is requested then line symbols are clipped to the outline, 
  otherwise lines are allowed to bleed a pixel or two beyond those 
  boundaries- for most cases this looks	fine but for fat lines it is 
  gonna look goofy regardless. In those cases use the KEYIMAGE.

- Fixed a bug in the scanline writer so that x coordinates can be in any 
  order when passed in to the function. (bug 336)

- Updated loadExpressionString in mapfile.c to be a bit more tolerant of
  input. Now if a string does not match the logical or regex pattern it is
  automatically cast as a string expression. Removes the need for silly quotes.


Version 4.0-beta1 (2003-06-06)
------------------------------

- Added imagemap outputformat, which makes possible use of client-side 
  imagemaps in browsers

- Added MySQL support for non-spatial OpenGIS Simple Features SQL stored data

- msQueryByShape and msQueryByFeature honor layer tolerances. In effect you
  can to buffered queries now. At the momoment only polygon select features
  are supported, but there's nothing inherent in the underlying computations
  that says lines won't work as well.

- Simple one-to-one joins are working again. Reworked the join code so that
  table connections are persistant within a join (across joins is a todo).
  Joins, like layers are wrapped with a connection neutral front end, that
  sets us up to do MySQL or whatever in addition to XBase.

- Removed shapepath argument to all layer access functions (affects MapScript).
  It's still used but we leverage the layer pointer back to the parent mapObj
  so the API is cleaner.

- Changed default presentation of feature attributes to escape a few 
  problematic characters for HTML display (eg. > becomes >). 
  Added [itemname_raw] substitution to allow access to unaltered data.

- Added initial version of Jan Hartman's connection pooling code.

- Replaced libwww with libcurl for WMS/WFS client HTTP requests.
  (libcurl 7.10 required, see http://curl.haxx.se/libcurl/c/)

- Added CONNECTION to the list of mapfile parameters that can accept 
  %variable% substitutions when processed by the cgi version. This is useful
  for passing in username and/or passwords to database data sources.

- Added support for DATA and TEMPLATE (header/footer/etc...) filtering using
  an regex declared in the mapfile (DATAPATTERN and TEMPLATEPATTERN). 
  Certain parameters in a mapfile cannot be changed via a URL without first
  being filtered.

- Added support for enviroment variable MS_MAPFILE_PATTERN. This allows you to
  override the default regex in favor of one more restrictive (I would hope) of
  your own.

- Disabled CGI SAVEMAP option.

- Removed CGI TEMPLATE option since you can use the map_web_template syntax.
  Simplifies security maintenance by only having to deal with this option 
  in a single place.

- Added offset support (styleObj) for raster based output (GD for sure, not
  quite sure how OGR output is created although I believe is uses GD anyway).
  This allows for feature drop shadows and support for cool linear symbols
  like used to be supported in pre-3.4 versions. These offsets are not 
  scalable at the moment.

- Null shapes (attributes but no vertices) are skipped for shapefiles using
  the msLayerNextShape interface. Otherwise applications should check the
  shapeObj type member for MS_SHAPE_NULL.

- Changed where label cache is allocated and cleared. Now it isn't allocated 
  until drawing takes place. Any old cache is cleared before a new one is
  allocated. The cache is still intact following rendering for post-processing
  using MapScript.

- Fixed screw up in pre-processing of logical expressions for item lists.
  Under certain circumstances that list could get corrupted and expressions
  would fail.

- Added NOT operator to expression parser.

- Added layer and map level DEBUG options to map file.

- Major changes to support vector output (PDF, SWF, GML, ...):
   - imageObj is used by all rendering functions instead of gdImagePtr
   - New msSaveImage() prototype

- Support for GD-2.0, including 24 bits output.  Dropped support for GD 1.x

- Support for output to any GDAL-supported format via the new OUTPUTFORMAT
  object.

- New styleObj to replace the OVERLAY* parameter in classes.

- PostGIS: Added Sean Gillies <sgillies at i3.com>'s patch for "using unique 
  <column name>". Added "using SRID=#" to specify a spatial reference 
  for an arbitrary sql query.

- ... and nuerous fixes not listed here...


Version 3.6.0-beta1 (2002-04-30)
--------------------------------

- MapScript: qitem and qstring params added to layer->queryByAttribute().
  Instead of being driven by the layer's FILTER/FILTERITEM, the query by
  attribute is now driven by the values passed via qitem,qstring, and the 
  layer's FILTER/FILTERITEM are ignored.

- Symbol and MapFile changes:
   ANTIALIAS and FILLED keywords now take a boolean (TRUE/FALSE) argument
   i.e.   ANTIALIAS becomes ANTIALIAS TRUE
   and    FILLED    becomes FILLED TRUE

- Reference Map:
  Added options to show a different marker when the reference box becomes
  too small.  See the mapfile reference docs for more details on the new 
  reference object parameters (MARKER, MARKERSIZE, MAXBOXSIZE, MINBOXSIZE)

- Added MINSCALE/MAXSCALE at the CLASS level.

- Support for tiled OGR datasets.

- PHP 4.1.2 and 4.2.0 support for PHP MapScript.

- Added LAYER TRANSPARENCY, value between 1-100

- Fixes to the SWIG interface for clean Java build.

- New HTML legend templates for CGI and MapScript.  See HTML-Legend-HOWTO.

- WMS server now supports query results using HTML query templates instead
  of just plain/text.

- Added support functions for thread safety (--with-thread).  Still not 
  100% thread-safe.


Version 3.5.0 (2002-12-18)
