Adobe released the final version of Lightroom 5.0 today. This is the first version that is available either through individual license or via an Adobe Creative Cloud subscription. New features include Smart Previews (allows you to edit and notate images offline), an Upright Tool (straightening and perspective correction), Radial Gradients, and an Advanced Healing Brush. Slideshows can now create HD video output, plus the Book module has been updated, as well.
Other less talked about new features include Windows HiDPI support (e.g. the Windows "Retina Display" ability), LAB Color info, and for Nikon users, D600 tethering support.
Upgrades from earlier versions are US$79.
