This is correct. > But in fact, this version of Poppler is based on Xpdf 3.03, which is > dual-licensed: GPLv2 or GPLv3. No, Poppler has been forked from some old GPLv2-only Xpdf version, and in 0.19.x all the modifications from Xpdf 3.03 were integrated. Still, Poppler is GPLv2-only, since it is a derived work from a GPLv2-only work. Poppler would have the same license as Xpdf 3.03 if it would have been rebased over that Xpdf version (like what LibreOffice people are doing, IIRC), which is not what happened. -- Pino Toscano
