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.

Springy Dock Tricks
If you drag a file and hover over Dock icons, various useful things happen which are similar to Finder springing. If it's a window, the window un-minimizes from the Dock. If it's a stack, the corresponding folder in the Finder opens. If it's the Finder, it brings the Finder to the foreground and opens a window if one doesn't exist already. But the coolest (and most hidden) springing trick is if you hover over an application and press the Space bar, the application comes to the foreground. This is great for things like grabbing a file from somewhere to drop into a Mail composition window that's otherwise hidden. Grab the file you want, hover over the Mail icon, press the Space bar, and Mail comes to the front for you to drop the file into the compose window. Be sure that Spring-Loaded Folders and Windows is enabled in the Finder Preferences window.
