My D5 uses a firmware version 160910. I do not have any trouble with it.
I can now see available a new version 20160928, but I do not know if download it or not.
Do you know the difference between the two firmware versions?
What is your advice, considering that my D5 with the 160910 firmware version works nicely and it allowed me to eliminate the battery issue I have had in the past?
Thank you in advance.
