+
+Reinier Heeres has ported John Porter's mplot3d over to the new
+matplotlib transformations framework, and it is now available as a
+toolkit mpl_toolkits.mplot3d. See the `examples

+
+axes grid toolkit
+-----------------
+
+Jae Joon has added a new toolkit to ease displaying multiple images in
+matplotlib, as well as some support for curvilinear grids to support
+the world coordinate system. See :ref:`axes_grid_users-guide-index`
+and `examples <http://matplotlib.sourceforge.net/examples/axes_grid/index.html>`_

+.. _whats-new-spine:

Axis spine placement
--------------------
Andrew Straw has added the ability to place "axis spines" -- the lines
-that denote the data limits -- in various arbitrary locations. See
+that denote the data limits -- in various arbitrary locations. No
+longer are your axis lines constrained to be a simple rectangle around
+the figure -- you can turn on or off left, bottom, right and top, as
+well as "detach" the spine to offset it away from the data. See
+:ref:`pylab_examples-spine_placement_demo` and
:class:`matplotlib.spines.Spine`.

==============================
It's been four months since the last matplotlib release, and there are
