Apple has now released Aperture 3.0.1, claiming to fix significant reported problems with the new edition of the professional photo management tool. Although every new software release endures some bumps after being exposed to systems outside its testing pool, I heard from many photographers, TidBITS readers, and other colleagues that Aperture 3 seemed as if it was shipped too early. (I've used it a little following its release earlier this month - see "Apple Releases Aperture 3," 9 February 2010 - and experienced one outright crash and sluggish behavior, but not enough to pass judgment.)
According to the release notes for version 3.0.1, the update improves overall stability and focuses on fixes for upgrading from earlier versions of Aperture and importing photos from iPhoto and directly from cameras. Memory usage is improved "when processing heavily retouched photos," and there are improvements to the new Faces and Places features, which all seemed to be problematic flash points for users.
Other changes include fixes when printing multiple images or contact sheets, editing photos using an external editor, displaying photos with Definition and Straighten adjustments applied, accessing Aperture libraries on a network volume, and more. The update is available via Software Update or as a standalone 29.41 MB download.
