- New functions/methods:
  - Two new functions, :py:func:`~xarray.combine_nested` and
    :py:func:`~xarray.combine_by_coords`, allow for combining datasets along any
    number of dimensions, instead of the one-dimensional list of datasets
    supported by :py:func:`~xarray.concat`.
    The new ``combine_nested`` will accept the datasets as a nested
    list-of-lists, and combine by applying a series of concat and merge
    operations. The new ``combine_by_coords`` instead uses the dimension
    coordinates of datasets to order them.
    :py:func:`~xarray.open_mfdataset` can use either ``combine_nested`` or
    ``combine_by_coords`` to combine datasets along multiple dimensions, by
    specifying the argument ``combine='nested'`` or ``combine='by_coords'``.
    The older function :py:func:`~xarray.auto_combine` has been deprecated,
    because its functionality has been subsumed by the new functions.
    To avoid FutureWarnings switch to using ``combine_nested`` or
    ``combine_by_coords``, (or set the ``combine`` argument in
    ``open_mfdataset``). (:issue:`2159`)
    By `Tom Nicholas <http://github.com/TomNicholas>`_.
  - :py:meth:`~xarray.DataArray.rolling_exp` and
    :py:meth:`~xarray.Dataset.rolling_exp` added, similar to pandas'
    ``pd.DataFrame.ewm`` method. Calling ``.mean`` on the resulting object
    will return an exponentially weighted moving average.
    By `Maximilian Roos <https://github.com/max-sixty>`_.
  - New :py:func:`DataArray.str <core.accessor_str.StringAccessor>` for string
    related manipulations, based on ``pandas.Series.str``.
    By `0x0L <https://github.com/0x0L>`_.
  - Added ``strftime`` method to ``.dt`` accessor, making it simpler to hand a
    datetime ``DataArray`` to other code expecting formatted dates and times.
    (:issue:`2090`). :py:meth:`~xarray.CFTimeIndex.strftime` is also now

- update to version 0.12.2:

:py:func:`~xarray.open_mfdataset` can use either ``combine_nested`` or
``combine_by_coords`` to combine datasets along multiple dimensions, by
specifying the argument ``combine='nested'`` or ``combine='by_coords'``.
The older function :py:func:`~xarray.auto_combine` has been deprecated,
because its functionality has been subsumed by the new functions.
To avoid FutureWarnings switch to using ``combine_nested`` or
``combine_by_coords``, (or set the ``combine`` argument in
``open_mfdataset``). (:issue:`2159`)
By `Tom Nicholas <http://github.com/TomNicholas>`_.
- :py:meth:`~xarray.DataArray.rolling_exp` and
:py:meth:`~xarray.Dataset.rolling_exp` added, similar to pandas'
``pd.DataFrame.ewm`` method. Calling ``.mean`` on the resulting object
will return an exponentially weighted moving average.
By `Maximilian Roos <https://github.com/max-sixty>`_.
- New :py:func:`DataArray.str <core.accessor_str.StringAccessor>` for string
related manipulations, based on ``pandas.Series.str``.
By `0x0L <https://github.com/0x0L>`_.
- Added ``strftime`` method to ``.dt`` accessor, making it simpler to hand a
datetime ``DataArray`` to other code expecting formatted dates and times.
(:issue:`2090`). :py:meth:`~xarray.CFTimeIndex.strftime` is also now
available on :py:class:`CFTimeIndex`.
By `Alan Brammer <https://github.com/abrammer>`_ and
`Ryan May <https://github.com/dopplershift>`_.
- :py:meth:`~xarray.core.GroupBy.quantile` is now a method of ``GroupBy``
objects (:issue:`3018`).
By `David Huard <https://github.com/huard>`_.
- Argument and return types are added to most methods on ``DataArray`` and
``Dataset``, allowing static type checking both within xarray and external
libraries. Type checking with `mypy <http://mypy-lang.org/>`_ is enabled in
CI (though not required yet).
By `Guido Imperiale <https://github.com/crusaderky>`_
and `Maximilian Roos <https://github.com/max-sixty>`_.
- Enhancements to existing functionality:
- Add ``keepdims`` argument for reduce operations (:issue:`2170`)
By `Scott Wales <https://github.com/ScottWales>`_.
- Enable ``@`` operator for DataArray. This is equivalent to :py:meth:`DataArray.dot`
By `Maximilian Roos <https://github.com/max-sixty>`_.
- Add ``fill_value`` argument for reindex, align, and merge operations
to enable custom fill values. (:issue:`2876`)
By `Zach Griffith <https://github.com/zdgriffith>`_.
- :py:meth:`DataArray.transpose` now accepts a keyword argument
``transpose_coords`` which enables transposition of coordinates in the
same way as :py:meth:`Dataset.transpose`. :py:meth:`DataArray.groupby`
:py:meth:`DataArray.groupby_bins`, and :py:meth:`DataArray.resample` now
accept a keyword argument ``restore_coord_dims`` which keeps the order
of the dimensions of multi-dimensional coordinates intact (:issue:`1856`).
By `Peter Hausamann <http://github.com/phausamann>`_.
- Better warning message when supplying invalid objects to ``xr.merge``
(:issue:`2948`). By `Mathias Hauser <https://github.com/mathause>`_.
- Add ``errors`` keyword argument to :py:meth:`Dataset.drop` and :py:meth:`Dataset.drop_dims`
that allows ignoring errors if a passed label or dimension is not in the dataset
(:issue:`2994`).
By `Andrew Ross <https://github.com/andrew-c-ross>`_.
- IO related enhancements:
- Implement :py:func:`~xarray.load_dataset` and
:py:func:`~xarray.load_dataarray` as alternatives to
:py:func:`~xarray.open_dataset` and :py:func:`~xarray.open_dataarray` to
open, load into memory, and close files, returning the Dataset or DataArray.
These functions are helpful for avoiding file-lock errors when trying to
write to files opened using ``open_dataset()`` or ``open_dataarray()``.
(:issue:`2887`)
By `Dan Nowacki <https://github.com/dnowacki-usgs>`_.
- It is now possible to extend existing :ref:`io.zarr` datasets, by using
``mode='a'`` and the new ``append_dim`` argument in
:py:meth:`~xarray.Dataset.to_zarr`.
By `Jendrik Jördening <https://github.com/jendrikjoe>`_,
`David Brochart <https://github.com/davidbrochart>`_,
`Ryan Abernathey <https://github.com/rabernat>`_ and
`Shikhar Goenka <https://github.com/shikharsg>`_.
- ``xr.open_zarr`` now accepts manually specified chunks with the ``chunks=``
parameter. ``auto_chunk=True`` is equivalent to ``chunks='auto'`` for
backwards compatibility. The ``overwrite_encoded_chunks`` parameter is
added to remove the original zarr chunk encoding.
By `Lily Wang <https://github.com/lilyminium>`_.
- netCDF chunksizes are now only dropped when original_shape is different,
not when it isn't found. (:issue:`2207`)
By `Karel van de Plassche <https://github.com/Karel-van-de-Plassche>`_.
- Character arrays' character dimension name decoding and encoding handled by
``var.encoding['char_dim_name']`` (:issue:`2895`)
By `James McCreight <https://github.com/jmccreight>`_.
- open_rasterio() now supports rasterio.vrt.WarpedVRT with custom transform,
width and height (:issue:`2864`).
By `Julien Michel <https://github.com/jmichel-otb>`_.
- Bug fixes:
- Rolling operations on xarray objects containing dask arrays could silently
compute the incorrect result or use large amounts of memory (:issue:`2940`).
By `Stephan Hoyer <https://github.com/shoyer>`_.
- Don't set encoding attributes on bounds variables when writing to netCDF.
(:issue:`2921`)
By `Deepak Cherian <https://github.com/dcherian>`_.
- NetCDF4 output: variables with unlimited dimensions must be chunked (not
contiguous) on output. (:issue:`1849`)
By `James McCreight <https://github.com/jmccreight>`_.
- indexing with an empty list creates an object with zero-length axis (:issue:`2882`)
By `Mayeul d'Avezac <https://github.com/mdavezac>`_.
- Return correct count for scalar datetime64 arrays (:issue:`2770`)
By `Dan Nowacki <https://github.com/dnowacki-usgs>`_.
- Fixed max, min exception when applied to a multiIndex (:issue:`2923`)
By `Ian Castleden <https://github.com/arabidopsis>`_
- A deep copy deep-copies the coords (:issue:`1463`)
By `Martin Pletcher <https://github.com/pletchm>`_.
- Increased support for `missing_value` (:issue:`2871`)
By `Deepak Cherian <https://github.com/dcherian>`_.
- Removed usages of `pytest.config`, which is deprecated (:issue:`2988`)
By `Maximilian Roos <https://github.com/max-sixty>`_.
- Fixed performance issues with cftime installed (:issue:`3000`)
By `0x0L <https://github.com/0x0L>`_.
- Test suite fixes for newer versions of pytest (:issue:`3011`, :issue:`3032`).
By `Maximilian Roos <https://github.com/max-sixty>`_
and `Stephan Hoyer <https://github.com/shoyer>`_.
- update to version 0.12.1:
- Enhancements:
- Allow ``expand_dims`` method to support inserting/broadcasting dimensions
with size > 1. (:issue:`2710`)
By `Martin Pletcher <https://github.com/pletchm>`_.
- Bug fixes:
- Dataset.copy(deep=True) now creates a deep copy of the attrs (:issue:`2835`).
By `Andras Gefferth <https://github.com/kefirbandi>`_.
- Fix incorrect ``indexes`` resulting from various ``Dataset`` operations
(e.g., ``swap_dims``, ``isel``, ``reindex``, ``[]``) (:issue:`2842`,
:issue:`2856`).
By `Stephan Hoyer <https://github.com/shoyer>`_.
