Apple released 10.5.5 on the 15th of September. According to Apple the update included the following improvements..

• Improves Spotlight indexing performance.
• Improves iPhone sync reliability with iCal and Address Book
• In MobileMe: improves overall sync and Back to My Mac reliability.
• Improves Time Machine reliability with Time Capsule.
• Addresses stability issues with video playback, processor core idling, and remote disc sharing for MacBook Air.

I was hoping this update would fix the long standing problem in Leopard of shared libraries not showing album artwork on the remote source. I have a Mac mini setup in my bedroom with a 20″ ACD and it is very frustrating seeing a placeholder instead of actual album art when scrolling through not just Music, but also Movies and TV Shows. Please Apple, fix this problem, as “gorgeous artwork” is what you love doing!
