As far as I know, there was only 1 firmware update and this is what it was for:
Firmware Version 1.0.1 incorporates the following fixes:
1. Corrects a phenomenon in which, when the playback grid is set to “6×4″, and a vertical image is displayed, or a horizontal image is rotated to be displayed vertically, the grid does not display correctly.
2. In languages other than Japanese, the phrase “no. of shots” has been corrected to “value” in the “Time-lapse movie settings > Interval/Shots” setting screen.
I would like to see Canon add to the menu a minimum shutter speed setting when in "auto ISO". I use this mostly in "P" mode. I also would like more functionality to the "in camera" editing of jpegs and raw files which would give the wireless transfer more meaning and use. I especially use the the ability to lighten and darken shots as well as white balance adjustments in post in-camera processing. The cameras computer can easily handle these processes on a single picture basis and renders the outcome quickly and I can then send the shot to my phone for distribution to friends like the phone camera. My Nikons give me all of the above abilities.
