Only 4D plug-ins in version 2003 can be loaded by 4th Dimension or 4D Server 2003. This does not apply to third-party plug-ins. These plug-ins are loaded normally in 4D 2003, regardless of their version. For compatibility issues with third party plug-ins, please contact their respective publishers.

Note Starting from 4th Dimension version 2003, old Macintosh 680xx-based plug-ins cannot be used in 4D databases.
