A lot of material was lost a very long time ago in a site crash. V2 was a very limited run.
That said it is all the same BOM and schematically. Cosmetic component placement changes only.
Be sure to use the actual T Pad for in and out Audio wiring and not the extra ground pad right beside by mistake. That was the main reason for a change at that time. We highlighted the silk screen for that T Pad. While we were at it we made a few minor cosmetic changes but nothing regarding how to build or populate.
I was able to find the advanced section online and take 3 screenshots.



I hope that helps.
