@@ -24,6 +24,22 @@ The following methods have been updated to support this:
   ``t_idx`` argument, which is the time index at which to plot the cuts. This
   defaults to ``t_idx=0``.
 
+When loading a set of netCDF files they will be lazily loaded along the time
+dimension (ie. only one file will be read into memory at any one time).
+
+When loading a set of HDF4 or HDF5 files all of them will be read into
+memory, so beware loading lots of them! Support for lazy loading may be
+implemented for HDF4 or HDF5 files in the future.

+Animations
+~~~~~~~~~~
+`Variable.plot_radial_cut`, `Variable.plot_phi_cut`, and
+`Variable.plot_equatorial_cut` now support animation creation. If multiple
+timesteps are loaded in the `Variable` and the timestep isn't specified, a
+:class:`~matplotlib.animation.Animation` object will be returend instead of
+a single plot being created. See the example gallery for more information on
+how to save the animation to disk.

 Other new features

 - Added :func:`~psipy.io.mas.convert_hdf_to_netcdf` to convert a set of HDF
