  • Massive tile set improvements
    • [New in Preview 2] Support for Mapbox Vector Tiles as tile output format MapGuide RFC 177
    • Support for UTFGrid as tile output format MapGuide RFC 159
    • MapGuide RFC 170
      • Support for meta-tile generation
      • Support for a localized version of the (previously serverconfig.ini global) TileExtentOffset setting
    • MapGuide RFC 173
      • Support for "retina" (aka. hi-dpi) tile generation
      • Removed tile set restrictions for MgMap creation
  • New APIs
    • [New in Preview 2] New init entry point to allow proper init of MapGuide API in a pure class library context MapGuide RFC 182
    • Geometry simplification APIs MapGuide RFC 153
    • Creating MgMap instances with initial display parameters MapGuide RFC 157
    • "Clean and simplified" JSON output in mapagent MapGuide RFC 158
      • mapagent operations that return feature data is outputted as GeoJSON under this mode

Known Issues

  • Java support is not operational on Linux possibly due to some missing configuration needed since migrating to Tomcat 9.x (all .jsp requests cause Tomcat to return HTTP status 403). This does not happen on Windows. We lack the resources to properly investigate the cause and prescribe a proper fix. If you are able to assist in this matter or know what the fix is, please reply to (this ticket: #2828) or reply to the mapguide-users mailing list.

Maestro Authoring Known Issues

The current release of MapGuide Maestro (6.0m10) has some known issues when connecting to a 4.0 preview 1 server. These issues will be addressed with the next milestone release.

FDO Notes

MGOS 4.0.0 Preview 2 is built against FDO trunk (rev 8021)

Due to unavailable build resources (the build maintainer does not have access to the ESRI SDK), this release does not include the ArcSDE FDO provider

FDO trunk (rev 8021) is near identical to FDO 4.1 in terms of functionality with the following changes:

  • Improved WFS services support for WFS FDO provider
  • MySQL Provider:
    • Support for the full suite of spatial operations for MySQL >= 5.6
    • Experimental support for MariaDB
    • Experimental support for MySQL 8.0
    • Improve SRID sampling query performance
  • PostGIS Provider:
    • Added support for PostgreSQL 12.0
    • No longer joins to pg_authid when listing tables/views
    • Support for curve strings and curve polygons
  • SHP Provider: Fix memory leaks in extended select implementation

The King Oracle provider now requires Oracle Instant Client 12cR2

Installer notes

You cannot use the windows installer to in-place upgrade an existing MapGuide Open Source 3.1.x or older installation. Only one MapGuide installation (via the Windows installer) can exist on any given machine. Use the InstantSetup bundle if side-by-side installs are required. Be sure to back up any data and applications before carrying out the new installation.

Before upgrading, it is recommended that you take a backup of your existing repository (whether that is through creating MGP packages with the MapGuide Site Administrator or using the provided repository backup tools/scripts)

Extra Files

Due to size constraints, the binary packages for this release of MapGuide omit the following CS-Map data files:

  • USA:
    • NSRS 2007/2011 datum shift files
    • 1996/1999/2003 Geoid height data files
  • Australia:
    • GDA 2020 datum shift files

These extra files are available for download as a separate 7-zip archive:

To install these files, extract the contents into your Dictionaries folder of your CS-Map installation. On Windows, this would normally be:

  • C:\Program Files\OSGeo\MapGuide\CS-Map\Dictionaries

Restart your MapGuide Server after extracting the files.

Unless you work with data in one or more coordinate systems that involves one of the above datums, you do not need these files.
