Today Adobe released ACR 6.1. This update is only for Photoshop CS5 and not earlier versions.
Support for several new cameras has been added in this update. Visit the Camera Raw page for a complete list of supported cameras. Also, Camera Raw 6.1 includes new lens correction functionality that can apply profile-based corrections to accommodate geometric distortions, chromatic aberration and lens vignette effects. Manual corrections for geometric distortion as well as vertical and horizontal perspective transforms are also available. A handful of lens profiles are included for automatic correction and more can be created by the community with the Adobe Lens Profile Creator.
Adobe recommends that you use the select “Updates” from the help menu and install this automagically. If that does not work, here are the links.
