Porkbarrel ver 2 vs. ver 1.5?

[Justus]

I have downloaded the build files for the Porkbarrel (the one that includes the single sided etch image) and, even though that etch image is in the Porkbarrel version 2 build file, the image itself says "Ver 1.5" on it.  Consequently, I also have the Porkbarrel 1.5 build file.  Are the differences such that the version 1.5 etched board still works for the version 2 of the circuit, and that's why there was no "Ver 2" etch image?


(Edit:  Actually, even in the version 2 build doc, the first pages calls it Version 4 - 10.04.10.  Confusing)
