 Revision history for Perl extension Imager::Graph.
 
-Imager-Graph 0.06 - unreleased
+Imager-Graph 0.10 - 7 May 2012
+=================
+
+ - loosen up image comparisons - the rounding change in Imager 0.90
+   made small changes to many pixels in fountain fills
+   https://rt.cpan.org/Ticket/Display.html?id=76955
+   It should fix the following too.
+   https://rt.cpan.org/Ticket/Display.html?id=68031
+
+ - negative_bg (or set via set_negative_background()) can now be a
+   fill.
+   https://rt.cpan.org/Ticket/Display.html?id=59532
+
+ - calculation of the zero position for horizontal charts was broken,
+   this resulted charts with negative data values having the
+   negative_bg color filled from the left side of the chart off the
+   right side of the image.
+
+ - Imager::Graph now requires at least perl 5.6.
+
+ - hoisted the common cmpimg() function into a separate test module
+
+ - convert shipped comparison images from ppm to png to reduce size
+
+Imager-Graph 0.09 - 05 Aug 2010
+=================
+
+Bug fixes:
+
+ - refresh the t10_lin_fount test image
+
+ - avoid use_automatic_axis() for the second area test, since systems
+   without Chart::Math::Axis will produce a different image.
+
+Imager-Graph 0.08 - 03 Aug 2010
+=================
+
+Now depends on Imager 0.75.
+
+More cool changes from Patrick Michaud:
+
+ - Area charts
+   https://rt.cpan.org/Ticket/Display.html?id=7
+
+Other changes:
+
+ - horizonal_gridlines (vertical charts) and vertical_gridlines
+   (horizontal charts) are now features and can be enabled like other
+   features (or disabled)
+
+ - hoisted the dashed-line drawing into Imager::Graph::_line() and
+   added a _get_line() method to retrieve line style information.
+
+ - features enabled earlier in the style list can now be disabled with
+   a feature "no{stylename}" when features are supplied as an arrayref
+   or scalar. eg. "nograph_outline".  If you supply features as a hashref
+   you can disable a feature with:
+     { stylename => 0 }
+
+ - for vertical and horizontal charts, allow the outline of the graph
+   area (graph_outline) to be disabled (with nograph_outline in
+   features.) or styled (graph.outline)
+
+ - for vertical and horizontal charts, allow the fill of the graph
+   area to be controlled separately from the base bg (graph.fill)
+
+ - tests
+
+Bug fixes:
+
+ - generate y-axis tic-label widths baed on the labels actually used.
+
+ - make draw() idempotent for vertical charts
+
+ - multiple calls to draw() no longer return the same image object
+
+ - labels supplied to draw() are now used for vertical and horizontal
+   charts
+
+ - Imager::Graph::Horizontal::add_column_data_series() renamed to
+   add_bar_data_series() and now adds the series as a "bar" series.
+   add_column_data_series() did nothing useful for a horizontal chart.
+
+
+Imager-Graph 0.07 - 21 May 2009
+=================
+
+Lots of cool changes from Patrick Michaud:
+
+ - added Bar, Column. StackedColumn and Line charts.
+   https://rt.cpan.org/Ticket/Display.html?id=5 [*]
+
+ - new ocean style
+
+ - new ocean_flat style
+
+ - methods to set chart style attributes, in addition to the style
+   parameters passed to draw().
+
+Bug fixes:
+
+ - missing a font parameter when we have a chart with text no longer
+   results in an exception, but in a false returned and a message in
+   error() as with other errors.
+   https://rt.cpan.org/Ticket/Display.html?id=2872
+
+ - the mono style now disables anti-aliasing by default
+
+[*] this was the oldest open bug on rt.cpan.org, now #7 is, still an
+Imager-Graph issue

    background, and made that the default, so the default graphs aren't
    quite so ugly.
