I have placed a test package for release 6.0.2 in the "testing" folder on SourceForge
    https://sourceforge.net/projects/gnuplot/files/gnuplot/testing/

The bug tracker has been pretty quiet lately so I hope most of the issues in the 6.0
releases have been reported and now are fixed in 6.0.2.

Please report any build problems or other issues you find with the test package.
If no problems arise I plan to use the same source files for a release announcement
in a couple of weeks.

		Gnuplot Version 6.0.2 Release Notes
		===================================

This is the second incremental release for gnuplot stable version 6.0.
In addition to the usual minor bug fixes, it contains several new features
from the development version of gnuplot that didn't quite make it into
the initial version 6 release.

NEW (backported from development version)
-----------------------------------------
- plot style "with hsteps" enables a variety of new plot types
  For examples, see
	* https://gnuplot.info/demo_6.0/hsteps.html
	* https://gnuplot.info/demo_6.0/logic_timing.html
	* https://gnuplot.info/demo_6.0/rank_sequence.html

- 3D plot style "with filledcurves" provides additional flexibility in creating
  the family of plot styles that includes waterfall plots and fence plots.
  See
	* https://gnuplot.info/demo_6.0/waterfallplot.html

- Terminal input when gnuplot is linked against the BSD editline library
  now correctly handles UTF-8 characters.  UTF-8 input has always worked
  for configuration options readline=gnu or readline=builtin; now it also
  works for
      ./configure --with-readline=bsd

  This change should in particular benefit users of Debian and MacOS
  binaries, which are typically linked against the editline library.

- Polygons in a 3D plot ("splot ... with polygons") can use palette coloring
  and pm3d lighting.

- General binary keyword option "blank=NaN" facilitates using binary input
  data for plot styles that would require blank lines in a text input data
  stream. See
	* https://gnuplot.info/demo_6.0/binary_polygon.html

- "linestyle variable" is accepted as a color specifier in plot commands.
  The primary distinction between this as "linecolor variable" is that
  linestyle properties are cleared by the next "reset" command.
  This allows definition of a temporary color sequence affected only one plot.

CHANGES
-------
- Local variables are reimplemented to provide a better-defined scope
  and faster evaluation of function blocks.
- Existing plot styles steps, histeps, fsteps, and fillsteps are
  reimplemented to use the new hsteps code.
- Boxplot outlier position (horizontal displacement) is controlled by "set jitter".
- The content of $GPVAL_LAST_MULTIPLOT is appended to the output from "save"
  so that loading the saved file regenerates a full multiplot rather than
  only the final component.

FIXES
-----
- reworked generation of logscale axis tic marks                 (Bugs 2372 2717)
- Do not save extraneous commands to $GPVAL_LAST_MULTIPLOT       (Bug 2714)
- svg: modify gnuplot_svg.js to work in local standalone mode    (Bug 2715)
- wxt: release per-thread font data before entering "persist"    (Bug 2693)
- "set table": honor "nosurface" keyword in splot
- "set table": honor "set format z" when z is printed from plot
- better contouring near the edge of a z-clipped surface
- handle mousing of logscale axes in inactive plot windows       (Bug 2723)
- "set tics scale" does not change other axis tick properties    (Bug 2724)
- points with variable color value NaN should not be drawn       (Bug 2737)
- "set term tikz nostandalone" should suppress the latex wrapper (Bug 2740)
- handle unusual case of intersecting pm3d surfaces              (Bug 2744)

KNOWN ISSUES
------------
- Support for replot and pan/zoom mouse operations in multiplot mode
  is still incomplete. Expect further improvement in subsequent releases.
