Apple has released iTunes 9.2 and OS X 10.6.4 in anticipation of the launch of the iPhone 4 next week.
The OS X Snow Leopard update contains all the usual security fixes and performance tweaks, includes Safari 5 for those who haven't already taken the plunge, and fixes a bunch of bugs.
iTunes 9.2 for Mac or Windows comes with several new features and improvements, many of which are related to the forthcoming iOS 4, Apple's recently-renamed mobile operating system which will be available from June 24th.
The update will allow iDevice fans with the latest iOS4-toting devices to sync all of thier digital media on the go, read and sync books with iBooks 1.1, use the new PDF functions in iBooks and organise apps using a familiar files and folders interface for the first time.
Back-up speeds have also been improved and Album artwork is snappier, according to Apple's release notes.
The new versions are both available using Software Update.
