On Thursday May 31st Apple release Aperture 3.2.4 to address some issues with the application. The update is 550MBs.
Noted revisions in the update:
- Improved Stability in Mac OSX Snow Leopard
- Address an issue that could prevent the Viewer from updating correctly after editing a photo using an external editor
The release seems to be stable, although I cannot say I noticed the issues that the update is supposed to have fixed.
