Along with the new iMac and the new iPod that were released during today's special press event, Apple has updated iTunes to version 6 and QuickTime to version 7.0.3.

Few information is available on these updates but we noticed that iTunes 6 provides a new video library feature, allowing users to manage and watch their videos directly from iTunes. The QuickTime update probably adds compatibility with the video content that Apple has made available today.

UPDATE:
Apple has made available the QuickTime 7.0.3 update through the Software Update utility with the following description:

QuickTime 7.0.3 delivers several important bug fixes, primarily in the areas of streaming and H.264 video. QuickTime 7 Pro users also gain the ability to create video and audio files that can be played back on compatible iPods. This update is highly recommended for all QuickTime 7 users.

Important Notice to QuickTime Pro Users: Installation of QuickTime 7 will disable the QuickTime Pro functionality in prior versions of QuickTime, such as QuickTime 5 or QuickTime 6. If you proceed with this installation, you must purchase a new QuickTime 7 Pro key to regain QuickTime Pro functionality. After installation, visit www.apple.com/quicktime to purchase a QuickTime 7 Pro key.
