Adobe has released the latest updates for Lightroom (3.6) and Camera Raw (6.6). Like the release candidates of a few weeks ago, they add support for 10 cameras, including Nikon's new V1 and J1 models. About two dozen lens profiles have been added as well.
Both updates also include about a dozen minor bug fixes. Minor, that is, if they didn't affect you. For complete details, see Tom Hogarty's Lightroom Journal.
