- 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>`_.

- update to version 0.12.3:
- New functions/methods:
- New methods :py:meth:`Dataset.to_stacked_array` and
:py:meth:`DataArray.to_unstacked_dataset` for reshaping Datasets of variables
with different dimensions
(:issue:`1317`).
This is useful for feeding data from xarray into machine learning models,
as described in :ref:`reshape.stacking_different`.
- Enhancements:
- Support for renaming ``Dataset`` variables and dimensions independently
with :py:meth:`~Dataset.rename_vars` and :py:meth:`~Dataset.rename_dims`
(:issue:`3026`).
- Add ``scales``, ``offsets``, ``units`` and ``descriptions``
attributes to :py:class:`~xarray.DataArray` returned by
:py:func:`~xarray.open_rasterio`. (:issue:`3013`)
- Bug fixes:
- Resolved deprecation warnings from newer versions of matplotlib and dask.
- Compatibility fixes for the upcoming pandas 0.25 and NumPy 1.17 releases.
- Fix summaries for multiindex coordinates (:issue:`3079`).

OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-xarray?expand=0&rev=21
- 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
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-xarray?expand=0&rev=18
- Just use %pytest macro
- Update to version 0.12.1:
- Enhancements
- Allow ``expand_dims`` method to support inserting/broadcasting dimensions
with size > 1. (:issue:`2710`)
- Bug fixes
- Dataset.copy(deep=True) now creates a deep copy of the attrs (:issue:`2835`).
- Fix incorrect ``indexes`` resulting from various ``Dataset`` operations
(e.g., ``swap_dims``, ``isel``, ``reindex``, ``[]``) (:issue:`2842`,
:issue:`2856`).
OBS-URL: https://build.opensuse.org/request/show/697053
OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/python-xarray?expand=0&rev=10

- Saving files with times encoded with reference dates with timezones
(e.g. '2000-01-01T00:00:00-05:00') no longer raises an error
(:issue:`2649`).
- Fixed performance regression with ``open_mfdataset`` (:issue:`2662`).
- Fixed supplying an explicit dimension in the ``concat_dim`` argument to
to ``open_mfdataset`` (:issue:`2647`).
