The Aperture 1.5.6 update is now available, and ensures that your version of Aperture is compatible with Leopard. You can update Aperture by running Software Update or by visiting the Aperture download page here.

Apple tells us that this update addresses performance related issues, improves stability, and of course supports compatibility with Leopad (duh!).

Quick note: Make sure you install this update before you open Aperture from Leopard.
