Apple has released iPod Software Updater 1.0.4 for Mac OS X 10.1 or later, and Mac OS 9.2.1.
The update adds two functions to the iPod - update and restore. The update command downloads new software to the iPod, and can be disabled if not needed.
Restore returns an iPod to its factory default setting before downloading new software.
There is also support for additional languages in this release, including Brazilian/Portuguese, Danish, Finnish, Norwegian, and Swedish.
iPod Software 1.0.4 Updater also remedies compatibility and performance problems in the last release.
