- 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>`_.

- Deprecations:
- :py:attr:`~core.accessor_dt.DatetimeAccessor.weekofyear` and :py:attr:`~core.accessor_dt.DatetimeAccessor.week`

with year, week, and weekday calculated according to the ISO 8601 calendar. Requires
pandas version 1.1.0 or greater (:pull:`4534`). By `Mathias Hauser <https://github.com/mathause>`_,
`Maximilian Roos <https://github.com/max-sixty>`_, and `Spencer Clark <https://github.com/spencerkclark>`_.
- :py:meth:`Dataset.to_zarr` now supports a ``region`` keyword for writing to
limited regions of existing Zarr stores (:pull:`4035`).
See :ref:`io.zarr.appending` for full details.
