Well, that didn't take long.
Less than four weeks after, the company has issued a release candidate for Lightroom 4.1 to squash bugs and add support for one of the hottest cameras going right now, the Canon 5D Mark III.
The 22-megapixel, full-frame SLR brings new low-light sensitivity, faster performance, overhauled autofocus, and other improvements over its 3-year-old predecessor. But until now, Lightroom fans who have the coveted $3,500 camera could only see its raw files by converting them into the Digital Negative format with Adobe's DNG Converter software.
Other improvements in the release candidate, according to Lightroom leader Tom Hogarty's blog post today:
Point Curve adjustments made in Lightroom 3 and before have been restored.
Lightroom 4 did not properly open external applications when using the "Edit In" functionality.
Addressed performance issues in Lightroom 4, particularly when loading GPS track logs, using a secondary monitor, and the controls within the Develop module.
Ability to update DNG previews and metadata for more than 100 photos has been restored.
This update allows for improved viewing of subfolders and stacks in folders with a large number of photos.
It was possible that a layout of a saved book could be lost after quitting Lightroom 4.
I'm looking forward to the GPS track fix, which took down my machines a few times when I was trying to geocode photos. Happily, since Lightroom performs nondestructive editing that leaves the original images intact, it didn't cause any problems beyond inconvenience.
Any performance gains when using adjustment sliders also is welcome: it's the heart of the software, and the improved controls are noticeably slower compared to Lightroom 3.x.
