XD2024 distributions :
XD2024 is supplied as precompiled executables for Windows & Linux platforms only. The functionality is identical, except that some features of XDGRAPH are unavailable in the Windows version.

The executables for the Windows platform are supplied in two formats, a console version which runs from the command line in an identical fashion to the Linux version, and the WinXD GUI version.

If there any problems using these executables, please contact Louis Farrugia.

Registered users may download distributions for any platform. The current version is 2024.01a (dated 23rd December, 2024). This is a minor update on version 2024.01, which corrects a small number of bugs. For the changes see XD2024 Modifications
