Arduino Yun release 5 is available, and fixed 5v pin/USB port problem.

Arduino Yun 5v pin/USB port doesnt provide 5 volt.

4.48 volt at 5v pin will cause some shield fail, and low voltage at USB port cause a lot of USB device fail.

Arduino Yun release 5 is fixed 5v pin/USB port problem, provide exactly 5 volt which I saw the demo at maker faire nyc yesterday.

There is a small R4 on my board - does that mean it is Version 4 ?
