Apple has released the latest update for iTunes, version 7.4.2.

The new version (available for both Mac and Windows systems) is designed to address an issue encountered when creating ringtones using iTunes Plus song purchases.

The release also includes bug fixes for improved stability and performance, but details on these have not been specified.

The update is designed primarily for those who have faced problems using the custom ringtone maker added in iTunes 7.4 earlier this month, typically seeing error message 42160 when trying to convert an iTunes Plus song.

The update is available through Software Update and for direct download from Apple's support website.
