Apple has posted the promised update to Front Row, supporting updates to iTunes and iPhoto and a significant security update, all currently available only via Software Update.

The Front Row update adds support for playing Shared Music, Photos and Movies residing on other Macs on your home network. It is only available on machines that shipped with the Apple IR remote control. The updates to iTunes (6.0.4) and iPhoto (6.0.2) presumably include support for the new Front Row shared media feature.

Security Update 2006-001 (details) includes a laundry list of fixes including closing the “open safe files” loophole used by the recent proof-of-concept worm/trojan horse and a change to iChat to prevent its use to distribute malicious software.

This is a significant security update so its probably a good idea to install it sooner rather than later.
