Dupin v2.8.4 Released

Over the weekend, I released a version of Dupin that was basically a simple maintenance release. However, it was then brought to my attention that a bug had been in existence since v2.8.2 which errantly moved files to the Trash when using Dupin to remove tracks from a playlist. This isn't an often-used feature—most users just want to delete the tracks and Trash the files from the entire library—but you can imagine the problem this would cause when the last thing you expected while just removing tracks from a playlist is to find that the files had been Trashed as well.

I have fixed that issue in version v2.8.4 of Dupin.

Dupin v2.8.2 Available

You're probably getting your iTunes library all in order to make it ready for a nice new operating system. If so, you'll want to pick up the latest version of Dupin, the iTunes Duplicates Manager.

This latest version fixes a few rare bugs: a case-sensitivity issue with files located on an NAS that prevented Purging, errant detection of iTunes Match being enabled when it actually isn't, a Selection Window flickering problem, no longer wheezes if you happen to move the iTunes Media folder while Dupin is running, and a few other way-out-there situations are accomodated.

You can get version 2.8.2 by using Dupin's "Check for Update..." command in its app menu, or download it directly from here.

This is a free update for registered users of v2.5 and later. Otherwise, Dupin is $15.

Dupin v2.8.0 Available

I waited a little longer between updates this time around, so Dupin has gained a feature point.

Dupin v2.8 has significant memory management and CPU fixes making it faster than ever. More info and download is here.

Dupin Lite v1.2.3 Released

Dupin Lite has the same powerful Get Dupes-Filter-and-Purge features as the original Dupin but with fewer power-user features. If you aren't interested in managing duplicate tracks as much as just identifying and eliminating them then Dupin Lite may be right for you.

Dupin Lite v1.2.3 clarifies the "cloud tracks detected" alert message. Update or purchase now at the Mac App Store.

Dupin v2.5.4 Released

I've posted an update to Dupin. The latest is version 2.5.4 (however, for a brief time, v2.5.3 was available).

The latest update is a maintenance release with some minor fixes: clarifies cloud track detection information, better detection of misconfigured iApps.plist file, fixes issue in v2.5.3 whereby the Purge dialogs do not appear correctly on some systems.
