There are problems currently, see

  https://savannah.gnu.org/bugs/?48033
  https://savannah.gnu.org/bugs/?48832

As far as I can tell, the default branch has introduced new
incompatibilities with gnuplot 4 as a result of changes made to support
improved features / changing syntax in gnuplot 5.

Personally I have no problem with this move, as long as an explict
dependency on gnuplot >= 5.0 is declared, or someone who cares about
gnuplot support puts in the effort and additional logic to continue to
work with gnuplot 4.2 / 4.4 / 4.6 / pick a version.

Right now, the scripts say the minimum version is 4.2.5. This is not
correct in practice, which is why I reported #48033 and set it as a
release blocker.
