2.07 Codename: Winter (released 23-Feb-2017)
 - More fixes to documentation (d-lamb's description of transparent fill)
 - Fix whitespace in the makefile.pl
 - Fix issues 57 & 61 (freezing on newer windows releases); probably also fixes 56.
 - fix issue 60 (problems with reset command making gnuplot5rc2 fail)
2.06 Codename: Fall released 1-Nov-2015
 - Minor fixes to documentation
 - Plots to output files now go to a sensible default location in the CWD,
   rather than to gnuplot's stdout.  
2.005 Codename: Spring released 6-May-2015
 - Workaround for deprecation of cairo library in MacOS 10.5
 - Correctly identify gnuplot 5.0
2.004 Codename: Dima released 20-Dec-2014
 - fixed a bug that caused version sensing to fail for alpha-builds of gnuplot.
 - Minor updates to plot option parsing (switching more options to accept hashes).
 - Several minor bug fixes.
2.003 Codename: Bug fixes released 17-Sep-2014
 - Added support for 'qt' terminal (thanks to Luis Mochan!)
 - wxt is marked as an interactive terminal ("int=>1").
 - ASCII handles NaN/binary correctly (works around gnuplot's inability to parse "NaN")
 - Curve options are not cumulative (except for "with") within a plot.
 - Deprecation of gnuplot 4.4-4.5 is now more strident
2.002 Codename: Refinements
 - removed (x|y|x2|y2|z|t)range curve options -- only plot options are supported for range spec.
   (This removes some weird corner cases in argument parsing, and doesn't affect normal plotting).
 - more permissive terminal option parsing -- omit terminal name to get the default terminal.
 - Moved changes from POD to CHANGES file
2.001 Unknown Release Date Codename: Minor Fixes
 - use object oriented checks for PDL type of arguments
2.0 Unknown Release Date Codename: Alien-Gnuplot
 - Use Alien::Gnuplot for initial contact and global configuration
 - Don't complain about 'with'-modifiers
 - Several edge-case bugs fixed (thanks, Dima)
 - Colorspec parsing is better (and regularized with a procedure call)
 - SIGPIPE crashes fixed (mixing gnuplot and forking used to be dangerous)
 - internal representation of tics specifiers is better
 - better handling of tics when x2 or y2 is specified
 - better handling of images when x2 or y2 is specified
1.5 Unknown Release Date Codename: Curve Option Cornucopia
 - complex 'with' specifiers are deprecated.
 - curve options exist for plot variants (line color etc.)
 - lines are dashed, by default
 - windows don't persist, by default
 - bad value support
 - fixed a justify problem
 - several minor cross-platform issues
1.4 Unknown Release Date Codename: Works on Windows (ick)
 - Many thanks to Chris Marshall and Juergen Mueck, who both tested endless variants as
   we troubleshot bizarre IPC problems under Microsoft Windows with Strawberry Perl.
 - default to ascii data transfer under Microsoft Windows (Juergen's hang issue)
 - do better at ignoring chatter on Microsoft Windows (intercept ascii data prompts with a regexp)
 - clean up test reporting
 - deprecate gnuplot <4.6 and issue warning (and accommodate some missing keywords)
 - autoranging fix
 - read_polygon fix
 - Many small tweaks to make Microsoft Windows support better
 - Updates to POD documentation
 - Improved terminfo reporting
 - mouse-enabled default terminals are detected properly (e.g. 'x11').
 - includes "imag" and "points" for people who are used to PDL::Graphics::PGPLOT.
 - more careful I/O handling in the pipe
 - Improved interrupt handling
 - Sends output to gnuplot in chunks if necessary (gets around choking limitations on some platforms)
 - Allows specifying different commands than just "gnuplot" via environment variable GNUPLOT_BINARY.
 - Detects available terminal types from Gnuplot on initial startup.
 - supports m?tics options with hash syntax
1.3 Unknown Release Date Codename: Compatibility
 - Tests do not fail on v4.2 Gnuplot (still used on BSD)
 - Better error messages in common error cases
 - Several Microsoft Windows compatibility fixes (thanks, Sisyphus!)
1.2 Unknown Release Date Codename: first working release
 - Handles communication better on Microsoft Windows (MSW has brain damage).
 - Improvements in documentation
 - Handles PDF output in scripts
 - Handles 2-D and 1-D columns in 3-D plots (grid vs. threaded lines)
0.01 Unknown Release Date Codename: first release
 - Handles communication with command echo on the pipe (for Microsoft Windows)
 - Better gnuplot error reporting
 - Fixed date range handling
