Apple has updated iTunes 6 within days of its release.

iTunes 6.0.1 (12.8MB) is available through Software Update and as the default iTunes download from the company's website.

Apple's relatively tight-lipped about the update, saying only that: "iTunes 6.0.1 features several stability improvements over iTunes 6."

It also warns users: "After purchasing music from the iTunes Music Store with iTunes 6 or later, you will also need to upgrade your other computers that purchase music from the iTunes Music Store to iTunes 6.0.1."
