Canon today released it's major firmware upgrade 2.0 for the 10D. The firmware is supposed to fix some minor bugs like: exposure compensation display when using the ST-2 wireless flash transmitter. Also the release time when using MD memory is improved as well as C.Fn-04 AE lock operations. The major reason for this upgrade is the support of PictBridge, the latest protocol to print directly from the camera without the use of a computer. The firmware update and instructions for installation can be found on this Bebit page.
