Apple’s iTunes has been bumped to version 10.4, receiving no user-level changes but gaining a 64-bit foundation for maximum performance on Mac OS X 10.7 Lion; the update also includes several unspecified performance and stability improvements. Apple notes that, due to the architectural changes entailed by the move to 64-bit, third-party plug-ins may stop working with this version of iTunes; if that happens, contact the individual plug-in developers for help.

View Extra Bluetooth Details in Snow Leopard
In Snow Leopard, Option-click the Bluetooth icon in the menu bar to view a few additional items in the Bluetooth menu. Specifically, it enables you to open three utility applications: Bluetooth Explorer, Bluetooth Diagnostic Utility, and PacketLogger. These are likely of interest primarily to experts, but if you're having troubles with Bluetooth, the Bluetooth Diagnostic Utility in particular may be useful. (These tools are available only if you've installed Apple's Developer Tools.)
