For those tracking… Adobe Photoshop Lightroom 4.1 was released. Check the Adobe Labs site for the latest download.
I’ve been using Lightroom on and off again since version 1 was released. I’ve been impressed with the flexibility of the application and the web/slideshow export features. I even uploaded a gallery of my images to the Lightroom Gallery site. If you haven’t tried it… it’s worth the time. Do beware it is beta software so you’ll need some thick skin to endure some of the bugs.
