Since I've heard from people who have been experimenting with the gnuplot
5.0 (rc1) build in recent Windows snapshots, here's a heads-up:
The Windows builds of gretl 1.9.91 (just released) do NOT include gnuplot
5.0. This is because gnulot 5.0 (CVS) currently has some bugs that we
don't want to foist on people. We have therefore dropped back to gnuplot
4.6.6 (that is, CVS on the 4.6 branch). This fixes some bugs in 4.6.5 and
does not, to our knowledge, contain new bugs.
No doubt gretl will transition to gnuplot 5.0 before long, but not yet.
