Dupin v2.0.4 Released
Just posted Dupin v2.0.4. This update fixes a problem with "Selection to iTunes Playlist" and a couple of other minor issues.
On another Dupin note: most likely this will be the last incarnation for Tiger/10.4 systems. The next revision, v2.1, and its descendants will be for Leopard and Snow Leopard only. However, v2.0.x will remain available and I will continue to upgrade v2.0.x for Tiger if future circumstances justify it.
