Adobe just released the public beta for the next version of Photoshop Lightroom 5, which will bring plenty of new features:

Advanced Healing Brush

Radial Filter

Upright

The beta program will run through June 30th, and you can download from here.

Bear in mind that this is a beta version, so it's still far away from a finished product, and do not uset it in production environment!
