According to the Loop, Apple has updated its new Aperture 3 application which among other things fixes that pesky memory leak chronicled earlier this month. Other fixes (there are many):
Upgrading libraries from earlier versions of Aperture Importing libraries from iPhoto Importing photos directly from a camera Memory usage when processing heavily-retouched photos Face recognition processing Adding undetected faces using the Add Missing Face button Printing pages containing multiple images Printing photos and contact sheets with borders and metadata Editing photos using an external editor Display of images with Definition and Straighten adjustments applied Zooming photos in the Viewer and in the Loupe using keyboard shortcuts Accessing Aperture libraries on a network volume Selecting and moving pins on the Places map Adding and editing custom locations using the Manage My Places window Switching between masters when working with RAW+JPEG pairs.
This update is recommended for all users of Aperture 3.
