   * Fixed UTF8 legality check to work under French Localization
   * #2863: Fix incorrect tile extent calculation at zoom=0 resulting in blank tiles
 * MapGuide API Bindings
   * Now generated with SWIG 4.1.1
   * .net: Fix proxy class resolution failure for certain MgGeometry classes
 * Web Tier / Applications
   * Fusion fixes:
     * Fix undefined `mapAgentUrl` in `getSiteVersion` function

   * #2844: New French string localization bundles for AJAX viewer and Fusion (contributed by Pierre Cardinal)
   * #2864: New webconfig.ini properties to allow denying mapagent `GETRESOURCECONTENT`/`GETRESOURCEDATA`/`GETRESOURCEHEADER` access to certain resources for `Anonymous` users or session ids.
   * #2297: Verified performance report now gracefully handles broken layers
   * OpenLayers library (for `application/openlayers` representation in WMS GetMap requests) now updated to `7.3.0`
   * GeoJSON output fixes and improvements
     * WFS/WMS:`crs` property now included so GeoJSON content can now self-identify its coordinate system
       * #2809: For WFS GetFeatures
       * #2858: For WMS GetFeatureInfo
     * #2857: Output from mapagent now has `application/json` mime type

== FDO Notes ==

MGOS 4.0.0 Beta 1 is built against FDO trunk (rev 8186)

'''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 8186) is near identical to FDO 4.1 in terms of functionality with the following changes:

 * Internal GDAL updated to 2.4.4
   * Internal copy of zlib updated to 1.2.12
 * Windows: Better swap-ability of internal GDAL dll with externally compiled one
   * OGR/GDAL/WMS providers changed to use GDAL/OGR C API surface to avoid potential ABI compatibility problems swapping with an externally compiled GDAL dll not compiled with the same MSVC compiler version we're using
   * Internal xalan/xerces dlls renamed with "fdo" suffix to avoid collisons with an externally compiled GDAL dll (that may bring its own copies of xalan/xerces dlls)
 * Better support and handling of empty geometries
 * Windows: Internal OpenSSL updated to `1.1.1k`
 * Windows: Internal libcurl updated to `7.73`
 * Fixed multiple memory leaks in GDAL provider 
 * Restore support for `Count(1)` expression in MySQL Provider
 * Improved WFS services support for WFS FDO provider
 * Improved WFS/WMS schema support for layer names with trailing underscores
 * SQL Server Provider:
   * Now supports databases hosted on SQL Azure PaaS
   * Improve SRID sampling performance
 * 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 is built against and 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:

 * [http://download.osgeo.org/mapguide/releases/4.0.0/Preview1/Dictionaries_Extra.7z Dictionaries_Extra.7z]
    * Size: 230,627,172 bytes
    * SHA-1: 798b189f88a2d50c71f1d01cfdcdeac9939ccb11

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**.
