Apple released its 10.6.1 update for iTunes yesterday. The patch fixes a number of minor bugs, mostly for the 64-bit Windows version of iTunes. The most major issue fixed is one that would cause iTunes to unexpectedly quit while playing videos, while changing artwork sizes in grid view, or when syncing photos to devices. Other fixes include interface elements that were incorrectly described by VoiceOver and WindowEyes, a problem that could cause iTunes to lock up when syncing to a iPod nano or iPod shuffle, and an issue regarding incorrect ordering while browsing TV episodes on the Apple TV.
Information about the security updates in this patch is not yet avaliable, as Apple "does not disclose, discuss or confirm security issues until a full investigation has occurred and any necessary patches or releases are avaliable."
The update can be obtained through an Apple software update or can be downloaded directly from Apple's support pages.
iTunes update 10.6 was released shortly after the announcement of the new iPad and new Apple TV. It included support for 1080p HD movies and TV shows from the iTunes store and provided improvement for iTunes Match, Apple's subscription service that adds music not purchased on iTunes to iCloud.
