Adobe has released Camera Raw 2.4 and DNG Converter 2.4 for Mac and Windows.
Camera Raw 2.4, an update to the plug-in for Photoshop CS that enables it to process RAW format files from a variety of digital cameras, adds official support for the Canon EOS 20D, EOS-1Ds Mark II, Powershot S70, Powershot G6 and several models from Konica Minolta.
DNG Converter 2.4 has also been updated to support the same new camera models as Camera Raw 2.4. In addition, it's now possible to embed the entire original RAW format file inside the DNG file, and extract it later if necessary.
Camera Raw 2.4 and DNG Converter 2.4 are available from Adobe's Photoshop downloads pages for Windows and Mac.
