I guess I should get that soon. But looks like they haven't fixed the bug that I keep seeing from time to time: it turns on eye control automatically. Especially when someone else is using the body, they get confused as it starts to focus at various places.

Hmm, I have never seen that. Any time Eye Focus is turned on, it's because I hit the button for it. I can see that being a problem, though.

Looks like I missed the 1.9 firmware update. There's a lot described there:

A password must be set initially.　•Adds the ability to review the history of any changes made to the password, network information, or other settings.　*For more information, please refer to the 'Setting a Password' section in the Advanced User Guide on cam.start.canon.
2. Enables firmware updates to be performed when the camera is connected to the internet and new firmware is made available on Canon servers.
3. Adds a function that simultaneously protects images when they are rated.
4. Adds the ability to use up to 8TB of CFexpress cards.　Note　- Cards larger than 8TB require low-level formatting by the camera.　- Cards larger than 8TB are treated as 8TB cards.　- Cards larger than 2TB cannot be used for firmware updating.
