I need to build a PDF 1.6 with LuaLaTeX, and I can't get \pdfminorversion command to work:
\pdfminorversion=6
\documentclass{article}
\begin{document}
This is a test
\end{document}
The result is
Undefined control sequence. \pdfminorversion
PdfLaTeX builds the PDF, but I need to use LuaLaTeX (I need the fontspec package).
