Nikon Japan (as expected) have just posted the Coolpix 950 v1.1 firmware update, uploadable from both PC and Mac via serial cable.

NOTE: *DO NOT* install this firmware on your Coolpix 950 unless you are in Japan and own a Japan purchased Coolpix 950, please wait for the international websites (noteably Nikontech USA; due July 30th) to post the ENGLISH version of the firmware. I have deliberately not posted the download URL (although it'd be easy enough for you to find) as I DO NOT want to encourage international Coolpix 950 owners to install this firmware.
