I have uploaded PCC 2.0.4.
This release improves a lot on predictions. If a ship does more than just moving, you can press Q on a ship screen to get an explanation what missions and actions are considered for fuel usage computation. This is intended to clean up the confusion whether your lfm order had been honored or not. On planets, Borg assimilation prediction was totally off previously. Tax prediction can now honor terraforming and Hisss.
The "export" function (and the c2export utility) can now save and restore an export setup to a file.
Among minor fixes, two major bugs have been fixed: you could previously create illegal turns by buying too many supplies using the undo-supply-sale function. Intercept chains could cause the list-ships function to crash.
