The MapServer Team is pleased to announce the release of the first beta
for the 5.6.0 release. We have decided to delay the 6.0 release a bit to
leave some time to stabilize the rendering enhancements that are planned
for 6.0, and to have a 5.6.0 release this fall which contains a few new
features and performance enhancements. Here is a quick summary:
New features in 5.6:
* MS RFC 51: XML Mapfile schema and XSLT (see
http://trac.osgeo.org/mapserver/wiki/XMLMapfiles)
* MS RFC 52: One-pass query processing, making WFS queries on
database backends much much faster
* MS RFC 55: Improve control of output resolution, allows printing
maps at printer resolution using a mapfile defined for screen resolution
* MS RFC 57: Labeling enhancements: ability to repeat labels along a
line/multiline
(RFCs are available online at http://mapserver.org/development/rfc/)
Preview features that will be fully functional only in 6.0:
* MS RFC 50: OpenGL Rendering Support
* MS RFC 54: Rendering Interface API
Other notable enhancements include:
* Security fixes (also backported to 5.4):
* Improved security relative to untrusted directories and mapfiles
(RFC 56)
* Fixed several security issues found in an audit of the CGI
application (#2939, #2941, #2942, #2943, #2944)
* Performance optimizations:
* Load all GDAL image bands in one pass for faster processing (r9260)
* Optimized access to very large shapefiles (#2930)
* Several enhancements/fixes to OGC Web Services specs support
* Several enhancements/fixes to all flavors of MapScript
As usual there an a large number of additional small enhancements and
bug fixes. For a complete list is the HISTORY.TXT file at:
http://svn.osgeo.org/mapserver/tags/rel-5-6-0-beta1/mapserver/HISTORY.TXT
We have started working in a 5.4 -> 5.6 migration guide. It will become
part of the official documentation soon, but in the meantime you can
view some draft content online at:
http://trac.osgeo.org/mapserver/browser/trunk/mapserver/MIGRATION_GUIDE.TXT
The release can be downloaded at:
http://mapserver.org/download.html OR

This is the first of three planned beta releases and if all goes well a
final release should occur on October 24th, the day of the FOSS4G Code
Sprint in Sydney. The full release plan can be viewed at:

We need your help to ensure a high quality product so please help out by
testing your applications with this new code base.
Thanks! - The MapServer Team
