Camera Raw 3.1 posted on Adobe FTP server RAW file support for the Canon EOS Digital Rebel XT/350D and Nikon D2X and other improvements. http://www.robgalbraith.com/bins/index.asp

NOTE: Be sure to do the Installation properly. You must remove the old Camera Raw.bi plug-in first. (Info for Windows users>) From Common Files AND from Program Files > CS2 only > Plug-ins > File Formats. (And follow the procedure in Elements 3.0 if you own Elements 3.0)

NOTE: Save the old plug-in (in another folder) in case you ever need it again.

And yes, it works perfectly with Elements 3.0 as well, although Adobe does not say so. i.e. I can use it to open and convert CR2 files from the Rebel XT. Natually, ACR in Elements 3.0 has fewer features than in CS2, but the new plug-in supports those features perfectly.
