MapGuide 1.2 Release Notes
This release is fully compatible with resources created using the previous MapGuide Open Source releases. If you uninstall the previous release and then install this one in the same location your existing Resource Database will be preserved.
This release is compatible with FDO 3.2.3.
Several changes have been made to web layout templates, especially for the AJAX viewer. If you have customised the template files, you will need to re-merge your changes.
Information about ECW and MrSID support and how to handle large amounts of raster data can be found at this page http://trac.osgeo.org/fdo/wiki/FdoGdalNotes.
