A colorbox feature has been added (a window which varies in color between red and green in synch with the sound). This seems to enhance the effect. An install target has been added to the Makefile. The number of harmonics used is now selectable on the command line. The package has been Debianized.
The release adds increased effectiveness by adding upper harmonics to the base frequency, a new utility to produce a .wav file suitable for burning to CDR from an AutoZen sequence file, volume which fades in when AutoZen is started and fades out when the user quits, and a play putton icon which changes based on what will actually happen when it is pressed (play, pause, or resume a sequence).
