I noticed that the developer of Raw Therapee (a nice cross platform raw converter) has released Version 2.3 Beta, with new support for the Nikon D300, Sony DSLR-A700, Olympus E-3 and Canon EOS-40D. It's based in part on Dave Coffin's dcraw.c
, and now supports more than 180 cameras.
See this forum post for more details on the new Version 2.3 Beta, and make sure to visit the main site at http://www.rawtherapee.com
For those who don't know about it, Raw Therapee
is a free RAW converter. If you decide to use it, I would encourage you to provide a small donation to the developer in appreciation for the hard work.
