using ``.to_dask_dataframe.`` (:issue:`6811`, :pull:`7472`).
- Accessing the property ``.nbytes`` of a DataArray, or Variable no longer
accidentally triggers loading the variable into memory.
- Allow numpy-only objects in :py:func:`where` when ``keep_attrs=True`` (:issue:`7362`, :pull:`7364`).
- add a ``keep_attrs`` parameter to :py:meth:`Dataset.pad`, :py:meth:`DataArray.pad`,

- Update to 2022.11.0
* This release brings a number of bugfixes and documentation
improvements. Both text and HTML reprs now have a new "Indexes"
section, which we expect will help with development of new
Index objects. This release also features more support for the
Python Array API.
## New Features

DatasetGroupBy.cumprod(). (PR5816) By Patrick Naylor
## Breaking changes
* repr(ds) may not show the same result because it doesn’t load
small, lazy data anymore. Use ds.head().load() when wanting to
see just a sample of the data. (GH6722, PR7203). By Jimmy
Westling.
* Many arguments of plotmethods have been made keyword-only.

+ The Dataset and DataArray rename" methods do not implicitly add
or drop indexes. (PR5692). By Benoît Bovy.
+ Many arguments like keep_attrs, axis, and skipna are now keyword
only for all reduction operations like .mean. By Deepak Cherian,
Jimmy Westling.
+ Xarray’s ufuncs have been removed, now that they can be replaced
by numpy’s ufuncs in all supported versions of numpy. By
Maximilian Roos.
+ xr.polyval() now uses the coord argument directly instead of its
index coordinate. (PR6548) By Michael Niklas.
* Bug fixes
+ Dataset.to_zarr() now allows to write all attribute types
supported by zarr-python. By Mattia Almansi.
+ Set skipna=None for all quantile methods
(e.g. Dataset.quantile()) and ensure it skips missing values for
float dtypes (consistent with other methods). This should not
change the behavior (PR6303). By Mathias Hauser.
+ Many bugs fixed by the explicit indexes refactor, mainly related
to multi-index (virtual) coordinates. See the corresponding
pull-request on GitHub for more details. (PR5692). By Benoît
Bovy.

+ Allow passing both other and drop=True arguments to
DataArray.where() and Dataset.where() (PR6466, PR6467). By
Michael Delgado.
+ Ensure dtype encoding attributes are not added or modified on
variables that contain datetime-like values prior to being
passed to xarray.conventions.decode_cf_variable() (GH6453,
PR6489). By Spencer Clark.
+ Dark themes are now properly detected in Furo-themed Sphinx
documents (GH6500, PR6501). By Kevin Paul.
+ Dataset.isel(), DataArray.isel() with drop=True works as
intended with scalar DataArray indexers. (GH6554, PR6579) By
Michael Niklas.
+ Fixed silent overflow issue when decoding times encoded with
32-bit and below unsigned integer data types (GH6589,
PR6598). By Spencer Clark.
+ Fixed .chunks loading lazy data (GH6538). By Deepak Cherian.
* Documentation

auto-enabled when flox is installed. Use
xr.set_options(use_flox=False) to use the old
algorithm. (GH4473, GH4498, GH659, GH2237, PR271). By Deepak
Cherian, Anderson Banihirwe, Jimmy Westling.

the corresponding pull-request on GitHub for more
details. (PR5692). By Benoît Bovy.

- Breaking changes:
- xarray no longer supports python 3.6
The minimum version policy was changed to also apply to projects with irregular
releases. As a result, the minimum versions of some dependencies have changed:
============ ====== ====
Package Old New
============ ====== ====
Python 3.6 3.7
setuptools 38.4 40.4
numpy 1.15 1.17
pandas 0.25 1.0
dask 2.9 2.11
distributed 2.9 2.11
bottleneck 1.2 1.3
h5netcdf 0.7 0.8
iris 2.2 2.4
netcdf4 1.4 1.5
pseudonetcdf 3.0 3.1
rasterio 1.0 1.1
scipy 1.3 1.4
seaborn 0.9 0.10
zarr 2.3 2.4
============ ====== ====
(:issue:`4688`, :pull:`4720`, :pull:`4907`, :pull:`4942`)
- As a result of :pull:`4684` the default units encoding for
datetime-like values (``np.datetime64[ns]`` or ``cftime.datetime``) will now
always be set such that ``int64`` values can be used. In the past, no units
finer than "seconds" were chosen, which would sometimes mean that ``float64``
values were required, which would lead to inaccurate I/O round-trips.
- Variables referred to in attributes like ``bounds`` and ``grid_mapping``
can be set as coordinate variables. These attributes are moved to
:py:attr:`DataArray.encoding` from :py:attr:`DataArray.attrs`. This behaviour
is controlled by the ``decode_coords`` kwarg to :py:func:`open_dataset` and
:py:func:`open_mfdataset`. The full list of decoded attributes is in
:ref:`weather-climate` (:pull:`2844`, :issue:`3689`)
- As a result of :pull:`4911` the output from calling :py:meth:`DataArray.sum`
or :py:meth:`DataArray.prod` on an integer array with ``skipna=True`` and a
non-None value for ``min_count`` will now be a float array rather than an
integer array.
- Deprecations:
- ``dim`` argument to :py:meth:`DataArray.integrate` is being deprecated in
favour of a ``coord`` argument, for consistency with :py:meth:`Dataset.integrate`.
For now using ``dim`` issues a ``FutureWarning``. It will be removed in
version 0.19.0 (:pull:`3993`).
By `Tom Nicholas <https://github.com/TomNicholas>`_.
- Deprecated ``autoclose`` kwargs from :py:func:`open_dataset` are removed (:pull:`4725`).
By `Aureliana Barghini <https://github.com/aurghs>`_.
- the return value of :py:meth:`Dataset.update` is being deprecated to make it work more
like :py:meth:`dict.update`. It will be removed in version 0.19.0 (:pull:`4932`).
By `Justus Magin <https://github.com/keewis>`_.
- New Features:
- :py:meth:`~xarray.cftime_range` and :py:meth:`DataArray.resample` now support
millisecond (``"L"`` or ``"ms"``) and microsecond (``"U"`` or ``"us"``) frequencies
for ``cftime.datetime`` coordinates (:issue:`4097`, :pull:`4758`).
By `Spencer Clark <https://github.com/spencerkclark>`_.
- Significantly higher ``unstack`` performance on numpy-backed arrays which
contain missing values; 8x faster than previous versions in our benchmark, and
now 2x faster than pandas (:pull:`4746`).
By `Maximilian Roos <https://github.com/max-sixty>`_.
- Add :py:meth:`Dataset.plot.quiver` for quiver plots with :py:class:`Dataset` variables.
By `Deepak Cherian <https://github.com/dcherian>`_.
- Add ``"drop_conflicts"`` to the strategies supported by the ``combine_attrs`` kwarg
(:issue:`4749`, :pull:`4827`).
By `Justus Magin <https://github.com/keewis>`_.
- Allow installing from git archives (:pull:`4897`).
By `Justus Magin <https://github.com/keewis>`_.
- :py:class:`DataArrayCoarsen` and :py:class:`DatasetCoarsen` now implement a
``reduce`` method, enabling coarsening operations with custom reduction
functions (:issue:`3741`, :pull:`4939`). By `Spencer Clark
<https://github.com/spencerkclark>`_.
- Most rolling operations use significantly less memory. (:issue:`4325`).
By `Deepak Cherian <https://github.com/dcherian>`_.
- Add :py:meth:`Dataset.drop_isel` and :py:meth:`DataArray.drop_isel`
(:issue:`4658`, :pull:`4819`).
By `Daniel Mesejo <https://github.com/mesejo>`_.
- Xarray now leverages updates as of cftime version 1.4.1, which enable exact I/O
roundtripping of ``cftime.datetime`` objects (:pull:`4758`).
By `Spencer Clark <https://github.com/spencerkclark>`_.
- :py:func:`open_dataset` and :py:func:`open_mfdataset` now accept ``fsspec`` URLs
(including globs for the latter) for ``engine="zarr"``, and so allow reading from
many remote and other file systems (:pull:`4461`)
By `Martin Durant <https://github.com/martindurant>`_
- :py:meth:`DataArray.swap_dims` & :py:meth:`Dataset.swap_dims` now accept dims
in the form of kwargs as well as a dict, like most similar methods.
By `Maximilian Roos <https://github.com/max-sixty>`_.
- Bug fixes:
- Use specific type checks in
:py:func:`~xarray.core.variable.as_compatible_data` instead of blanket
access to ``values`` attribute (:issue:`2097`)
By `Yunus Sevinchan <https://github.com/blsqr>`_.
- :py:meth:`DataArray.resample` and :py:meth:`Dataset.resample` do not trigger
computations anymore if :py:meth:`Dataset.weighted` or
:py:meth:`DataArray.weighted` are applied (:issue:`4625`, :pull:`4668`). By
`Julius Busecke <https://github.com/jbusecke>`_.
- :py:func:`merge` with ``combine_attrs='override'`` makes a copy of the attrs
(:issue:`4627`).
- By default, when possible, xarray will now always use values of
type ``int64`` when encoding and decoding ``numpy.datetime64[ns]`` datetimes. This
ensures that maximum precision and accuracy are maintained in the round-tripping
process (:issue:`4045`, :pull:`4684`). It also enables encoding and decoding standard
calendar dates with time units of nanoseconds (:pull:`4400`).
By `Spencer Clark <https://github.com/spencerkclark>`_ and `Mark Harfouche
<http://github.com/hmaarrfk>`_.
- :py:meth:`DataArray.astype`, :py:meth:`Dataset.astype` and :py:meth:`Variable.astype` support
the ``order`` and ``subok`` parameters again. This fixes a regression introduced in version 0.16.1
(:issue:`4644`, :pull:`4683`).
By `Richard Kleijn <https://github.com/rhkleijn>`_ .
- Remove dictionary unpacking when using ``.loc`` to avoid collision with ``.sel`` parameters (:pull:`4695`).
By `Anderson Banihirwe <https://github.com/andersy005>`_.
- Fix the legend created by :py:meth:`Dataset.plot.scatter` (:issue:`4641`, :pull:`4723`).
By `Justus Magin <https://github.com/keewis>`_.
- Fix a crash in orthogonal indexing on geographic coordinates with ``engine='cfgrib'``
(:issue:`4733` :pull:`4737`).
By `Alessandro Amici <https://github.com/alexamici>`_.
- Coordinates with dtype ``str`` or ``bytes`` now retain their dtype on many operations,
e.g. ``reindex``, ``align``, ``concat``, ``assign``, previously they were cast to an object dtype
(:issue:`2658` and :issue:`4543`).
By `Mathias Hauser <https://github.com/mathause>`_.
- Limit number of data rows when printing large datasets. (:issue:`4736`, :pull:`4750`).
By `Jimmy Westling <https://github.com/illviljan>`_.
- Add ``missing_dims`` parameter to transpose (:issue:`4647`, :pull:`4767`).
By `Daniel Mesejo <https://github.com/mesejo>`_.
- Resolve intervals before appending other metadata to labels when plotting (:issue:`4322`, :pull:`4794`).
By `Justus Magin <https://github.com/keewis>`_.
- Fix regression when decoding a variable with a ``scale_factor`` and ``add_offset`` given
as a list of length one (:issue:`4631`) by `Mathias Hauser <https://github.com/mathause>`_.
- Expand user directory paths (e.g. ``~/``) in :py:func:`open_mfdataset` and
:py:meth:`Dataset.to_zarr` (:issue:`4783`, :pull:`4795`).
By `Julien Seguinot <https://github.com/juseg>`_.
- Raise DeprecationWarning when trying to typecast a tuple containing a :py:class:`DataArray`.
User now prompted to first call `.data` on it (:issue:`4483`).
By `Chun Ho Chow <https://github.com/chunhochow>`_.
- Ensure that :py:meth:`Dataset.interp` raises ``ValueError`` when interpolating
outside coordinate range and ``bounds_error=True`` (:issue:`4854`,
:pull:`4855`).
By `Leif Denby <https://github.com/leifdenby>`_.
- Fix time encoding bug associated with using cftime versions greater than
1.4.0 with xarray (:issue:`4870`, :pull:`4871`). By `Spencer Clark <https://github.com/spencerkclark>`_.
- Stop :py:meth:`DataArray.sum` and :py:meth:`DataArray.prod` computing lazy
arrays when called with a ``min_count`` parameter (:issue:`4898`, :pull:`4911`).
By `Blair Bonnett <https://github.com/bcbnz>`_.
- Fix bug preventing the ``min_count`` parameter to :py:meth:`DataArray.sum` and
:py:meth:`DataArray.prod` working correctly when calculating over all axes of
a float64 array (:issue:`4898`, :pull:`4911`). By `Blair Bonnett <https://github.com/bcbnz>`_.
- Fix decoding of vlen strings using h5py versions greater than 3.0.0 with h5netcdf backend (:issue:`4570`, :pull:`4893`).

- This release brings the ability to write to limited regions of ``zarr`` files, open zarr files with :py:func:`open_dataset` and :py:func:`open_mfdataset`, increased support for propagating ``attrs`` using the ``keep_attrs`` flag, as well as numerous bugfixes and documentation improvements.:
- Deprecations:
- :py:attr:`~core.accessor_dt.DatetimeAccessor.weekofyear` and :py:attr:`~core.accessor_dt.DatetimeAccessor.week`
have been deprecated. Use ``DataArray.dt.isocalendar().week``
instead (:pull:`4534`). By `Mathias Hauser <https://github.com/mathause>`_,
`Maximilian Roos <https://github.com/max-sixty>`_, and `Spencer Clark <https://github.com/spencerkclark>`_.
- :py:attr:`DataArray.rolling` and :py:attr:`Dataset.rolling` no longer support passing ``keep_attrs``
via its constructor. Pass ``keep_attrs`` via the applied function, i.e. use
``ds.rolling(...).mean(keep_attrs=False)`` instead of ``ds.rolling(..., keep_attrs=False).mean()``
Rolling operations now keep their attributes per default (:pull:`4510`).
By `Mathias Hauser <https://github.com/mathause>`_.
