+  Version 1.9: 
 
+  zlib's source has been included again to fix compilation problems on
+MacOS. The embedded copy will only be used if tioga does not manage to
+link to the system one.
 
+  It is now possible to use directly a HLS image using 'color_space' =
+'HLS' as argument to show_image.
+
+  A new ticks placement algorithm was written. You can benefit from it
+by saying t.vincent_or_bill = true.
+
+  You can now use the optional argument to show_legend to draw a
+background (or anything else) to a legend. The information given to
+the callback will only be accurate if t.measure_legends = true. See
+samples/plots.rb
+(Legend_Inside_with_Background_using_legend_background) for more
+information. Accordingly, you can use legend_text_width to know the
+legend's text maximal width. 
+
+  A new utility function was written, show_grid, that draws a grid
+according to major and optionally minor ticks of the current axes.
+
+  show_marker can now take arrays for 'marker' and 'color', and cycles
+through them while plotting.
+
+  Some top-level convenience functions have been added:
+FigureMaker.exec, FigureMaker.make_pdf,
+FigureMaker.def_enter_page_function, FigureMaker.page_style that work
+on the default FigureMaker.
+
+  show_plot_without_clipping, obviously a non-clipping version of
+show_plot.
+
+  And all corresponding demonstrations in the samples/ directory !

     Are you feeling lucky?  If so, try QUICK_INSTALL.  This simply does
 the steps for you that are described below.  The install needs to copy some
 files to the ruby directory.  On the Mac, this probably means you need to do
