A little update to Aperture 3.3 has dropped, as Aperture 3.3.1. You can get it from Software Update or the App Store or from here, as usual.
The only fix it lists is “Fixes an issue that in rare cases could cause Aperture to hang or quit unexpectedly when upgrading libraries”, which was definitely an issue reported here by a few users, so that’s good to see.
I’m also hoping that there’s an undocumented fix here to allow importing of presets again. I’m on a slow connection so the upgrade will take overnight; however if any of you can test by installing any ApertureExpert preset that has textures (so the Textures or Film sets) that have had previous problems installing and let me know in the comments, I’d appreciate it!
