Specifically, this update:
* makes the game run natively on MacOS X Tiger/Leopard machines;
* adds zooming to full screen modes;
* allows the choice of the screen mode among those notified by the system;
* replaces zooming routines with more optimized ones (especially 3x and 4x);
* adds the possibility of disabling interpolation (for slow computers);
* adds the possibility of disabling the rendering of barriers;
* improves a bit the original themes;
* enriches slightly the Evil Masters AI;
* adds timer ticking during time-limited missions;
* adds map zooming;
* adds the option of sorting missions by difficulty;
* allows the use of joypads/joysticks with just 1 button;
* fixes the following bugs: bad joypad handling (detection was inhibited by a '2' in place of a '1'; sometimes up/down movement could stick); [PAGE UP/DOWN] handling (repeat delay handling was missing); a bad optimization of ray-tracing routine (which had no practical effects thanks to the way maps and themes were made);
* improves and extends the user's manual;
* links the AmigaOS 4 version to libSDL 1.2.13;
* applies some other minor changes.
