If you're looking to keep your iTunes install up-to-date or are planning on loading up the new iOS 6 beta, you'll need to ensure you have the latest iTunes installed.
Luckily, Apple has thought ahead in that area as always and has gone ahead and released iTunes 10.6.3. This release isn't only made to developers, it's a consumer release so it is available for all to download right now.
