-- For non-standard calendars commonly used in climate science, xarray will now
-  always use :py:class:`cftime.datetime` objects, rather than by default try to
-  coerce them to ``np.datetime64[ns]`` objects.  A
-  :py:class:`~xarray.CFTimeIndex` will be used for indexing along time
-  coordinates in these cases. A new method,
-  :py:meth:`~xarray.CFTimeIndex.to_datetimeindex`, has been added 
-  to aid in converting from a  :py:class:`~xarray.CFTimeIndex` to a
-  :py:class:`pandas.DatetimeIndex` for the remaining use-cases where
-  using a :py:class:`~xarray.CFTimeIndex` is still a limitation (e.g. for
-  resample or plotting).  Setting the ``enable_cftimeindex`` option is now a
-  no-op and emits a ``FutureWarning``. 
-- ``Dataset.T`` has been removed as a shortcut for :py:meth:`Dataset.transpose`.
-  Call :py:meth:`Dataset.transpose` directly instead.
-- Iterating over a ``Dataset`` now includes only data variables, not coordinates.
-  Similarily, calling ``len`` and ``bool`` on a ``Dataset`` now  
-  includes only data variables
-- Finished deprecation cycles:

-- Xarray's storage backends now automatically open and close files when
-  necessary, rather than requiring opening a file with ``autoclose=True``. A
-  global least-recently-used cache is used to store open files; the default
-  limit of 128 open files should suffice in most cases, but can be adjusted if
