Apple's freshly released [Aperture 1.5](http://www.apple.com/aperture/) has a slew of new features, bringing a much-needed maturity to the (nearly) year-old application. According to the ["What's New"](http://www.apple.com/aperture/newfeatures/index.html) page, Aperture 1.5 "takes advantage of enhanced AppleScript and Automator support: operate on image selections (in addition to projects and albums); filter for the “pick†of each stack; automate the export of master files with associated XMP metadata."
