Version 3.70

It appears that this has been released but only seems to be available for the USB download and not the "over wifi" method. The wifi method worked great for me for V3.56 so hoping it will be an option for 3.70.

It is available for WiFi update already. Need the display connected to the Internet and choose Check for Software Update in the General menu. Or...if have Connect to Internet set to "When Necessary", it'll popup and ask if you want to update when the display is powered on.

@TheReaper is correct and wi-fi is the easiest method.
