From macrumors.com:
Apple released iTunes 7.2 updated in the Mac OS X Software Update tonight, which offers support for “iTunes Plus”, Apple’s new DRM-free $1.29 offerings announced in April.
With iTunes 7.2, preview and purchase iTunes Plus music—new higher-quality, DRM-free music downloads from participating music labels.
Despite the software update, the Apple iTunes Store itself does not show any DRM-Free music currently available for purchase. The DRM-Free launch will likely occur later this morning (Wed, May 30th).
