+Change in default font
+----------------------
+
+The default font used by matplotlib in text has been changed to DejaVu Sans and
+DejaVu Serif for the sans-serif and serif families, respectively. The DejaVu
+font family is based on the previous matplotlib default --Bitstream Vera-- but
+includes a much wider range of characters.
+
+The default mathtext font has been changed from Computer Modern to the DejaVu
+family to maintain consistency with regular text. Two new options for the
+``mathtext.fontset`` configuration parameter have been added: ``dejavusans``
+(default) and ``dejavuserif``. Both of these options use DejaVu glyphs whenever
+possible and fall back to STIX symbols when a glyph is not found in DejaVu. To
+return to the previous behavior, set the rcParam ``mathtext.fontset`` to ``cm``.
