Adobe has released Lightroom 4.2 with a number of fixes applied to the professional photo cataloging and editing application. The update includes a fix for stacked photos that were hidden in both the Grid view and Filmstrip, resolves a problem with publishing videos to Facebook, ensures that Lightroom photo can be edited as JPEGs in Photoshop Elements, and fixes an issue with carriage returns in either the Title or Caption field that invalidated a Flickr upload. The release also adds support for 22 new cameras (though offering just preliminary support for the Nikon D600) and 43 new lenses. ($149 new, free update, 407 MB, release notes)
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
