 New in Matplotlib 2.1
 =====================
 
+Enhancements to polar plot
+--------------------------
+
+The polar axes transforms have been greatly re-factored to allow for more
+customization of view limits and tick labelling. Additional options for view
+limits allow for creating an annulus, a sector, or some combination of the two.
+
+The :meth:`~matplotlib.axes.projections.polar.PolarAxes.set_rorigin` method may
+be used to provide an offset to the minimum plotting radius, producing an
+annulus.
+
+The :meth:`~matplotlib.projections.polar.PolarAxes.set_theta_zero_location` now
+has an optional :code:`offset` argument. This argument may be used to further
+specify the zero location based on the given anchor point.

+The :meth:`~matplotlib.axes.projections.polar.PolarAxes.set_thetamin` and
+:meth:`~matplotlib.axes.projections.polar.PolarAxes.set_thetamax` methods may
+be used to limit the range of angles plotted, producing sectors of a circle.

+
+Previous releases allowed plots containing negative radii for which the
+negative values are simply used as labels, and the real radius is shifted by
+the configured minimum. This release also allows negative radii to be used for
+grids and ticks, which were previously silently ignored.
+
+
+
+Merge JSAnimation
+-----------------
+
+Jake Vanderplas' JSAnimation package has been merged into matplotlib. This
+adds to matplotlib the `~matplotlib.animation.HTMLWriter` class for
+generating a javascript HTML animation, suitable for the IPython notebook.
+This can be activated by default by setting the ``animation.html`` rc
+parameter to ``jshtml``. One can also call the ``anim_to_jshtml`` function
+to manually convert an animation. This can be displayed using IPython's
+``HTML`` display class::
+
+    from IPython.display import HTML
+    HTML(animation.anim_to_jshtml(anim))
+
+The `~matplotlib.animation.HTMLWriter` class can also be used to generate
+an HTML file by asking for the ``html`` writer.
