Used Nikon 1 V1 Firmware question

Hi everyone. I just recently purchased a V1 and an Ft1 adaptor. The firmware version on this camera is still 1.0. The only version I can find is 1.40. My question is do I download that firmware version, or do I have to download the previous versions and work my way up to 1.40? And if downloading previous versions is necessary, where do I find the older versions? Thank you for your help. Used Nikon 1 V1 Firmware question
