Lightroom 3.2 and Camera Raw 6.2 are now available as final releases on Adobe.com and through the update mechanisms available in Photoshop CS5 and Lightroom 3.
This means now is my turn to release the new version (1.18) of the MobileMe plugin, which has been in beta testing for over a month, and is ready for prime time. The update will be posted today, in the next 3-4 hours. Stay tuned.
