I just found that there have been many firmware upgrades for my current Nikon camera after I bought it around 2 years ago.
The latest "C" firmware version available is 1.12, while I had 1.02.
I want to figure out what changed or improved from what I had before.
Please note that I can see the most recent change on their download page like this:
Changes from “C” Firmware Version 1.11 to 1.12
Added support for the following features of AF-P lenses:
If the standby timer expires after the camera has focused, the focus position will not change when the timer is reactivated.
In manual focus mode, the focus indicator in the viewfinder (or in live view, the focus point selected in the monitor) will flash to show that infinity or the minimum focus distance has been reached by rotating the focus ring.
- Fixed the following issues:
- When pictures were viewed after shooting with Overflow selected for Role played by card in Slot 2 in the PHOTO SHOOTING MENU, the camera would sometimes display the second-last picture taken.
- Microphone sensitivity would sometimes not be correctly adjusted when movies were recorded with Auto sensitivity > Microphone sensitivity.
