Adobe has released 'Release Candidates' of Photoshop Lightroom 2.3 and Camera Raw 5.3 for immediate download from Adobe Labs. Both provide additional Raw support for the Nikon D3X and Olympus E-30 DSLRs. Lightroom is also now available in 8 new languages. The 'release candidate' label means the downloads are 'well tested' but not yet final versions.
