A new version of firmware, 1.0.1, has been released for the Canon EOS 10D. I think it must win the award for the most unexciting update ever, as it only corrects 2 very minor things:

1. It increases the reliability of USB communication when used with the camera direct print.
2. It corrects wrong simplified Chinese letters on MENU.
