iTunes 7.6.2, QuickTime 7.4.5, FrontRow 2.1.3, Keynote 4.0.3 and AirPort Utility 4.2.5 are available from the Software Update.
It seems Apple is fixing some security issues with QuickTime:

Apple is quietly adding several key anti-hacker security features into its flagship QuickTime media player as part of a deliberate plan to reduce the effectiveness of malicious exploits

eWeek writes.

All of these updates fix security, performance and stability issues.

I guess, we are getting used to have a FrontRow update with every iTunes & QT update.
