Version 6.0.3 Release Notes

- TeXLive2024 pdflatex does not like some of the UTF-8 characters in the user manual.
  The distribution includes a pre-built copy of gnuplot.pdf but if you want
  to rebuild it from the source in docs/gnuplot.doc please use lualatex instead.
  You can either replace the definition PDFLATEX=pdflatex with PDFLATEX=lualatex
  in the Makefile or provide this in the environment during configuration
        PDFLATEX=lualatex ./configure

The Makefile already requires lualex for the Japanese documentation.
Maybe it is time to require it also for the English documentation.
