gnuplot.lua:612: attempt to call a nil value (global 'unpack')

[YunanChen]

It is said that the global unpack has being changed to table.unpack at lua5.2 and 5.3. Have you fixed your code to enabled backward compatibility？

It seems that this issue has not been fixed yet. Do you have any solutions to solve this problem? Must I use Lua with a lower version?
