+------------------------------------------------------------

+`~.hist2d` now uses `~.pcolormesh` instead of `~.pcolorfast`,
+which will improve the handling of log-axes.  Note that the
+returned *image* now is of type `~.matplotlib.collections.QuadMesh`
+instead of ``~.matplotlib.image.AxesImage`.
