a7iv firmware update to v1.1

Sony a7iv firmware update to v1.1 has been announced.
Apparently to enhance the following:

- Improves shutter reliability
- Fixes an issue where the movie file rotated by the camera may not be rotated when displayed on a computer

Important: When updating from v1.01 or earlier, you need to update to v1.05 first before updating to v1.11. The install will fail if you try to update to v1.11 directly from v1.00 or v1.01.

Same as previously you need to format a memory card, download the driver to your computer, transfer the driver to your formatted memory card, load your camera with a fully charged battery, insert the card into slot 1, go to Menu - Set-up - Set-up Option - Version - Software Update.

The update takes about 6 minutes to load, and progress is indicated by the blinking access light on the camera: first single flashes, then 3 flashes and finally 5 flashes. When the update is complete the camera reboots.

I've updated assuming it's worth doing.
