1.6.11 Other changes and additions

Since gnuplot 4.0, `unset <something>` is preferred to `set no<something>`. The older form has been deprecated. Version 4.2 continues to allow the older syntax, but such backwards compatibility may be lost in future versions.

Commands of the form `set <something> <style>` also are deprecated in favor of the more general form `set style <something> <options>`. Many more plot elements now have style options of their own, including arrows, filled areas, lines, and points. There are also style settings for input data and formatting. Please see style, decimalsign, and datafile.

The MS Windows package includes an additional executable `pgnuplot.exe` to support piping command through standard input, which is otherwise not available for graphical applications on this system.
