Xconq version 7 is not directly compatible with any previous version of Xconq, although most of the basic game concepts remain unchanged. If you've played Xconq before, you should have little trouble getting used to the differences.
If you've designed any games (periods, maps, or scenarios) for version
5, you will discover many changes. Version 5 of Xconq used a mix of
crude fixed-format syntax and a simple postfix language for game designs
(which were then called "periods"). This version has changed too
radically to be able to read any of the old period, map, or scenario
files. In fact, version 7 eliminates the formal distinctions between
"period", "map", and "scenario". Therefore, if you have old
Xconq files, you should invest the time to convert. You may even
discover that some of the new features of Xconq provide a better
solution to your design problems. (The shell scripts per2game,
map2game, and scn2game will help you get started on
conversion; you can find them in the misc directory.)
