Looks like adobe sent out the latest update to Lightroom. 1.3 for Mac or Win (a free update for LR owners) is now available on Adobe’s website.
It’s primarily a Camera Raw support update, and also gives compatibility for Leopard users.
Heres what John Knack said about the update on his blog…
Lightroom 1.3 improves compatibility with Mac OS X Leopard, fixes some bugs, and adds an option to render 1:1 previews during import. New cameras supported in Lightroom, Camera Raw, and the DNG Converter include the following: Canon EOS 1Ds Mark III, Canon PowerShot G9, Nikon D3, Nikon D300, Olympus E-3, Olympus SP-560 UZ, and Panasonic DMC-L10. The applications also now support the sRAW format produced by the Canon 1D Mk III, 1Ds Mk III, and 40D.
