MapServer 4.8.0 released

[Daniel Morissette]

Good Morning,

MapServer 4.8.0 has just been released. The source package is available 
in the download area of the website and you can expect compiled binaries 
to become available shortly at the usual locations:
http://mapserver.gis.umn.edu/download/current/

Since the creation of the MapServer Technical Steering Committee in 
August, new features are now tracked via RFC documents. You can browse 
the complete list of RFCs at http://mapserver.gis.umn.edu/development/rfc

The relevant RFCs for this 4.8 release are:

  * MS RFC 2: Creating line features and/or shapes using WKT
  * MS RFC 3: Layer Plug-in Architecture
  * MS RFC 4: MapServer Raster Resampling
  * MS RFC 5: MapServer Horizon Reprojection Improvements
  * MS RFC 6: Color Range Mapping of Continuous Feature Values
  * MS RFC 8: Pluggable External Feature Layer Providers

Once again, all the details are available in the RFC documents at the 
URL above.

Another important enhancement in this release that is not documented in 
a RFC is the support for fuzzy brushes which allows producing 
antialiased thick lines when ANTIALIAS TRUE is set in a STYLE. For more 
details look for the "Fuzzy brushes and antialiased lines" thread in the 
mapserver-users list archives.

This release also includes a large number of small enhancements and bug 
fixes that didn't deserve their own RFC. I have included a copy of the 
list of changes/fixes since 4.6 from the HISTORY.TXT at the end of this 
message.

   prevent problems with more than 128 classes (bug 1633)

- Fixed possible crash with default content-type and POST requests.(bug 
1628)

- Known issue: MapScript queryByAttributes() creates wrong WHERE clause on
   postgis layers in some cases (patch available, see bug 1629)


Version 4.8.0-rc3 (2006-01-25)
------------------------------

- Add gml:lineStringMember in GML2 MultiLineString geometry (bug 1569).

- Move gBYTE_ORDER inside the pg layerinfo structure to allow for 
differently
   byte ordered connections (bug 1587).

- Close file handle when saving symbolset.

- Fix the memory allocation bug in sdeShapeCopy (Bug 1606).

- Fixed OGR WKT support (Bug 1614).

- Added shapeObj::toWkt() and ms_shapeObjFromWkt() to PHP MapScript (bug 
1466)

- Detect/add -DHAVE_VSNPRINTF in configure script and prevent systematic
   buffer overflow in imagemap code when vsnprintf() not available (bug 
1613)


Version 4.8.0-rc2 (2006-01-09)
------------------------------

- Commit fix for GD on win32 when different heaps are in use. (Bug 1513)

- Correct bound reprojection issue with ogc filer (Bug 1600)

- Correct mapscript windows build problem when flag USE_WMS_SVR was
   not set (Bug 1529)

- Fix up allocation of the SDE ROW_ID columns and how the functions that
   call it were using it. (bug 1605)

- Fixed crash with 3D polygons in Oracle Spatial (bug 1593)


Version 4.8.0-rc1 (2005-12-22)
------------------------------

- Fixed shape projection to recompute shape bounds. (Bug 1586)

- Fixed segfault when copying/removing styles via MapScript. (Bug 1565)

- Fixed segfault when doing attribute queries on layers with a FILTER 
already
   set but with no FILTERITEM.


Version 4.8.0-beta3 (2005-12-16)
--------------------------------

- Initialize properly variable in php mapscript (Bug  1584)

- New support for pseudo anti-aliased fat lines using brushes with variable
   transparency.

- Arbitrary rotation support for vector symbols courtesy of Map Media.

- Support for user-defined mime-types for CGI-based browse and legend
   templates (bug 1518).

- mapraster.c: Allow mapresample.c code to be called even if projections
   are not set on the map or layer object.  This is no longer a requirement.
   (Bug 1562)

   (Bug 1576)

   found (bug 1419)

- PostGIS layer test cases and fix for broken views and sub-selects (bug 
1443).

- SDE: Removed (commented out) support for SDE rasters at this time.  As 
far
   as I know, I'm the only one to ever get it to work, it hasn't kept up 
with
   the connection pooling stuff we did, and its utility is quite limited in
   comparison to regular gdal-based raster support (projections,
   resampling, etc) (HB - bug 1560).

- SDE: Put msSDELayerGetRowIDColumn at the top of mapsde.c so things
   would compile correctly.  This function is not included (or necessary)
   in the rest of the MS RFC 3 layer virtualization at this time.

- WFS : TYPENAME is manadatory for GetFeature request (Bug 1554).

- SLD : error parsing font parameters with the keyword "normal" (Bug 1552)

- mapgraticule.c: Use MIN/MAXINTERVAL value when we define grid position 
and
   interval (bug 1530)

- mapdrawgdal.c: Fix bug with nodata values not in the color table when
   rendering some raster layers (bug 1541).

- mapogcsld.c : If a RULE name is not given, set the class name to 
"Unknown"
   (Bug 1451)

Version 4.8.0-beta2 (2005-11-23)
--------------------------------

- Use dynamic allocation for ellipse symbol's STYLE array, avoiding the
   static limitation on the STYLE argument values. (bug 1539)

- Fix bug in mapproject.c when splitting over the horizon lines.

- Fix Tcl mapscript's getBytes method (bug 1533).

- Use mapscript.i in-place when building Ruby mapscript, copying not 
necessary
   (bug 1528).

   1522).

- correct msGetVersion to indicate if mapserver was build with MYGIS 
support.

- Fixed hang in msProjectRect() for very small rectangles due to round off
   problems (bug 1526).


Version 4.8.0-beta1 (2005-11-04)
--------------------------------

- Bug 1509: Fixed bounding box calculation in mapresample.c. The bottom 
right
   corner was being missed in the calculation.

- MS RFC 2: added OGR based shape<->WKT implementation.

- mapgdal.c: fixed some mutex lock release issues on error conditions.

- MS RFC 8: External plugin layer providers (bug 1477)

- SLD : syntax error when auto generating external symbols (Bug 1508).

- MS RFC 3: Layer vtable architecture (bug 1477)

   preparequery is called (Bug 1334).

- msProjectShape() will now project the lines it can, but completely
   delete lines that cannot be projected properly and "NULL" the shape if
   there are no lines left. (Bug 411)

- Expose msLayerWhichShapes and msLayerNextShape in MapScript. (bug 1481)

- Added support to MapScript to change images in a previously defined
   symbol. (bug 1471)

- mapogcfiler.c : bug 1490. Crash when size of sld filters was huge.

- Fixed --enable-point-z-m fix in configure.in (== -> =) (bug 1485).

- Extra scalebar layer creation is prevented with a typo fix in mapscale.c.
   Good catch, Tamas (bug 1480).

- mapwmslayer.c : use transparency set at the layer level on wms client
                   layers  (Bug 1458)

- mapresample.c: added BILINEAR/AVERAGE resampling options.

- mapfile.c: avoid tail recursion in freeFeatureList().

- maplegend.c: fixed leak of imageObj when embedding legends.

   temporary filenames. (bug 1312)

- SLD external graphic symbol format tests now for mime type
   like image/gif instead of just GIF. (bug 1430)

- Added support for OGR layers to use SQL type filers (bug 1292)

- mapio/cgiutil - fixed POST support in fastcgi mode. (bug 1259)

- mapresample.c - ensure that multi-band raw results can be
   resampled. (bug 1372)

- Add support in OGC FE for matchCase attribute on
   PropertyIsEqual and PropertyIsLike  (bug 1416)

- Fixed sortshp.c to free shapes after processing to avoid major
   memory leak. (bug 1418)

- fixed msHTTPInit() not ever being called which prevented msHTTPCleanup()
   from properly cleaning up cUrl with curl_global_cleanup(). (bug 1417)

- mapsde.c: add thread locking in msSDELCacheAdd
