Just got this from Adobe:
Adobe today announced the Lightroom 3.2 and Camera Raw 6.2 Release Candidates, available for immediate download on Adobe Labs. The updates extend raw file support to 12 new popular camera models, improve on several of the lens correction profiles introduced as part of the Lightroom 3 and Camera Raw 6.1 releases, and add over 50 new lens profiles to help photographers automatically correct for undesirable distortion and aberration effects.
In addition, the Lightroom 3.2 Release Candidate now allows Lightroom 3 customers the ability to publish their photos directly to Facebook from within the application, and addresses issues reported by customers on the Lightroom 3.0 release. Adobe continues to encourage the community to provide feedback on the updates so it can ensure the highest quality experience for customers working on a variety of hardware and software configurations.
Lightroom is the essential digital photography workflow solution, helping serious amateur and professional photographers quickly import, manage, enhance and showcase all their images from one application. The Photoshop Camera Raw plug-in provides fast and easy access within Photoshop to the raw image formats produced by many leading digital cameras.
