Please [wiki:SubmitTicket report any defects].

== Compatibility ==
Click [wiki:2.1MigrationInstructions here] for instructions on how to migrate to MGOS 2.1 from older releases.

MGOS 2.1.0 is compatible with [http://fdo.osgeo.org/content/fdo-340-downloads FDO 3.4.0].

If you are running Windows 2000, there may be issues if you have multiple PHP installations. The [http://trac.osgeo.org/mapguide/ticket/657 php extension that is supposed to resolve this issue] was built with APIs that do not exist in Windows 2000.

== FDO ==

Some RDBMS FDO providers may not work out of the box without the proper libraries installed. For example: 

 * PostGIS provider requires libpq.dll 
 * King.Oracle provider requires Oracle Instant Client

This normally happens if you installed MapGuide on a different machine from where the RDBMS is installed. To fix this, copy the required libraries into the MapGuide Server's FDO directory and restart your MapGuide Server.

== API changes ==

== Disk Space ==

The installer requires at least 1.5GB of disk space on C: during installation. Otherwise installation may not proceed.

If you do not have sufficient space on C:, you can open the installer file with [http://www.7-zip.org 7-zip] and extract the contents to another drive, and run the extracted setup.exe from there.  It may also be helpful to set your TEMP environment variable to a different drive.
