Release Notes: Unpkg has been entirely rewritten in Python. It now works with multiple packages at once, and extracts 10.5-style packages (as well as nested ones, and in 10.4 as well). Unpkg has also been upgraded to a WebKit-based interface, over the old CocoaDialog one.
Release Notes: This release incorporates fixes for possible security holes and makes explicit the fact that the project is released under the GNU GPL.
Release Notes: unpkg is now a Universal Binary. It sports a highly-revised backend and a completely new interface, with Cocoa dialogs, progress bars, file choosers, and error messages instead of the old text console output.
Release Notes: This release is compatible with Mac OS 10.4.
