The last time I looked at the petition, it was coming up on 300 signatures.
From reading your post, Thomas, it sounds a bit as if you've missed the last word from Ralph on this, where he made it clear there would be no new version released. This was even after Andreas Magerl from APC&TCP had offered to finance the whole printing.
I'm still interested in purchasing both a physical and digital copy if he decides to release the updated version. If not, then I hope he would at least consider releasing the previous English version in digital format.
