Apple has released Aperture 3.2.4, which promises improved stability for the professional photo organizer and editor when running on Mac OS X 10.6 Snow Leopard. The only other item noted for this maintenance release is a fix for an issue that prevented the Viewer from updating correctly after editing a photo using an external editor.

Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
