   Gnuplot 6.0.3 <https://gnuplot.sourceforge.net/ReleaseNotes_6_0_3.html>

The release tarball differs from the testing tarball by a fix to report the correct
version on the splashpage (stupid mistake on my part, sorry!).  Thanks to everyone
who tested the pre-release package.

There is nothing very exciting in this release, but it does include a few
minor features back-ported from the development version:

• In previous gnuplot versions all 3D polygons, objects, and filled areas shared
  a single border color and linewidth taken from "set pm3d".
  This limitation is now removed; border properties can be specified per-plot or
  per-object. This change affects any scripts that expected "set pm3d" to affect
  the borders of 3D polygons and boxes.

• splot ... "with contourfill at base"   ("at base" is new)
 
• Input data to plot and splot can be filtered through a conditional expression
  outside the "using" section.  For example:
      plot DATA using 2:3 with boxes if (stringcolumn(1) eq "ABC")

• New command "save changes" is equivalent to the old contributed external script
  gpsavediff. This command saves only the program settings, variables, and
  functions that distinguish the current state from the program state at the start
  of the current gnuplot session.

• Revised wxt terminal driver (linux) with more robust threading and error recovery.

happy gnuplotting
