You may note that the splash screen on Lightroom 2.1 mentions Camera Raw 4.6 as being the compatible version. This is slightly confusing as the latest version of Camera Raw is 5.1. However they are considered equivalent, so if you have Lightroom you are running Camera Raw 5.1!

This confusion was caused because Lightroom 2.0 was released before Photoshop CS4.

Lightroom 2.1 (Mac, Win), Camera Raw 5.1 (Mac, Win) and the DNG Converter 5.1 are now available on Adobe.com. New camera models are supported.

The beta versions of the Camera Profiles and DNG Profile Editor on Adobe Labs have also both been updated.  The Profile update includes additional profiles and incremental improvements to the previous beta profiles.  The DNG Profile Editor includes minor enhancements.

See Tom Hogarty’s Lightroom Journal post for more information.

Photoshop CS4 has been released with Camera Raw 5; this offers Lightroom 2.0 parity. However, Tom Hogarty mentions that a 5.1 update will happen next week to add support for some of the new cameras released recently.

Eric Chan has mentioned in this post, that Adobe are preparing a beta 2 release of camera profiles which will be released soon via the Adobe Labs site.
