Adobe has released updates to Lightroom 4 and Camera Raw 7. Each contains support for new camera models and lenses plus quite a few bug fixes. There is also an important and very welcome correction to the demosaic algorithms associated with cameras based on the Fuji X-Tran sensor. Who said Adobe doesn’t listen to user feedback?
Another very welcome bug fix relates to the Lightroom Slideshow module. However, the bug only effected a relatively small group of Mac OS users with a dual display set up. Basically, these users, which included myself, have been unable to use the Slideshow module since Lr4.3 was released.
