Well as soon as I finished writing the previous post I discovered that the update has been released, here's what Apple had to say:
"Aperture 1.0.1 Update addresses a number of issues related to reliability and performance. It also delivers improved image export quality and metadata handling."
Among the key areas addressed are:
- White balance adjustment accuracy and performance
- Image export quality
- Book and print ordering reliability
- Auto-stacking performance
- Custom paper size handling
