Aperture Exporter 1.1.7 Released
AE 1.1.7 introduces a new advanced feature: The option to create XMP sidecar files for JPEG originals. This is useful for those migrating to something other than Adobe Lightroom (which does not read sidecar files for JPEGs). This option also results in quicker exports.
