MapServer 4.8.0 released

Daniel Morissette-2
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.

------------------------------------------------------------


Version 4.8.0 (2006-02-02)
--------------------------

- Treat classindex as an int instead of a char in resultCacheMemberObj to
   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).

- Finished implementation of OGR Shape2WKT function (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)

- PDF : adding dash line support (Bug 492)

- 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

- Expose maximum lengths of layer, class, and style arrays in mapscript (bug
   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).

rasters
   (bug 1506).

- support wms_attribution element for LAYER's (Bug 1502)

- Correct php/mapscript bug : initialization of scale happens when
   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.

- msGDALCleanup(): better error handler cleanup.

   temporary filenames. (bug 1312)

   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

MapServer 4.8.1 released (was: MapServer 4.8.0 released)

Daniel Morissette-2
A bug was introduced between 4.8.0rc3 and the 4.8.0 release that broke
support for POST requests.

We've had to pull the 4.8.0 release and issue a new MapServer 4.8.1 with
this bug fixed:
   http://mapserver.gis.umn.edu/download/current/

Sorry about this.

Daniel


Version 4.8.1 (2006-02-03)
--------------------------

- Fixed bug introduced by previous fix to set default content-type in
   POST requests. (bug 1628)
