The "Documentation" tab of the Yun Rev2's product page is very sparse and missing important information that is not available on the Getting Started page either. It is not explained that digital pins 4, 6, 8, 9, 10, and 12 may be used as analog pins A6-A11.
I believe most of the information from the original Yun's "Documentation" tab is still correct so this should mostly just be a copy/paste operation. The one difference I'm aware of is this statement:
VIN. The input voltage to the Arduino board. Unlike other Arduino boards, if you are going to provide power to the board through this pin, you must provide a regulated 5V.
Is no longer correct. Even though the Yun Rev 2 product photos show that pin labeled "Vin" on the silkscreen and header, this pin is not Vin. It is 5V_OUT (https://forum.arduino.cc/index.php?topic=612894).
