The last update to Apple’s professional photo organizer and editor added iCloud compatibility, but didn’t quite dial in fixes for a few issues. Now, Aperture 3.2.2 looks like the version that works out those kinks. In addition to resolving an issue with iCloud and Photo Stream, Aperture displays magnification levels correctly using the loupe, uses the correct color profile for externally edited images under Mac OS X 10.7 Lion, fixes a crash under Lion that could occur when using brushes, makes the app behave correctly in full-screen mode, and more.

They still didn't manage to fix the colour profile bug. I don't know what they did fix, but it wasn't that.
