- update to version 0.15.0: - This release brings many improvements to xarray's documentation: our examples are now binderized notebooks (`click here <https://mybinder.org/v2/gh/pydata/xarray/master?urlpath=lab/tree/doc/examples/weather-data.ipynb>`_): - and we have new example notebooks from our SciPy 2019 sprint (many thanks to our contributors!).: - This release also features many API improvements such as a new: :py:class:`~core.accessor_dt.TimedeltaAccessor` and support for :py:class:`CFTimeIndex` in :py:meth:`~DataArray.interpolate_na`); as well as many bug fixes. - Breaking changes: - Bumped minimum tested versions for dependencies: - numpy 1.15 - pandas 0.25 - dask 2.2 - distributed 2.2 - scipy 1.3 - Remove ``compat`` and ``encoding`` kwargs from ``DataArray``, which have been deprecated since 0.12. (:pull:`3650`). Instead, specify the ``encoding`` kwarg when writing to disk or set the :py:attr:`DataArray.encoding` attribute directly. By `Maximilian Roos <https://github.com/max-sixty>`_. - :py:func:`xarray.dot`, :py:meth:`DataArray.dot`, and the ``@`` operator now use ``align="inner"`` (except when ``xarray.set_options(arithmetic_join="exact")``; :issue:`3694`) by `Mathias Hauser <https://github.com/mathause>`_. - New Features: - :py:meth:`DataArray.sel` and :py:meth:`Dataset.sel` now support :py:class:`pandas.CategoricalIndex`. (:issue:`3669`) By `Keisuke Fujii <https://github.com/fujiisoup>`_. - Support using an existing, opened h5netcdf ``File`` with :py:class:`~xarray.backends.H5NetCDFStore`. This permits creating an :py:class:`~xarray.Dataset` from a h5netcdf ``File`` that has been opened using other means (:issue:`3618`). By `Kai Mühlbauer <https://github.com/kmuehlbauer>`_. - Implement ``median`` and ``nanmedian`` for dask arrays. This works by rechunking to a single chunk along all reduction axes. (:issue:`2999`). By `Deepak Cherian <https://github.com/dcherian>`_. - :py:func:`~xarray.concat` now preserves attributes from the first Variable. (:issue:`2575`, :issue:`2060`, :issue:`1614`) By `Deepak Cherian <https://github.com/dcherian>`_. - :py:meth:`Dataset.quantile`, :py:meth:`DataArray.quantile` and ``GroupBy.quantile`` now work with dask Variables. By `Deepak Cherian <https://github.com/dcherian>`_. - Added the ``count`` reduction method to both :py:class:`~core.rolling.DatasetCoarsen` and :py:class:`~core.rolling.DataArrayCoarsen` objects. (:pull:`3500`) By `Deepak Cherian <https://github.com/dcherian>`_ - Add ``meta`` kwarg to :py:func:`~xarray.apply_ufunc`; this is passed on to :py:func:`dask.array.blockwise`. (:pull:`3660`) By `Deepak Cherian <https://github.com/dcherian>`_. - Add ``attrs_file`` option in :py:func:`~xarray.open_mfdataset` to choose the source file for global attributes in a multi-file dataset (:issue:`2382`, :pull:`3498`). By `Julien Seguinot <https://github.com/juseg>`_. - :py:meth:`Dataset.swap_dims` and :py:meth:`DataArray.swap_dims` now allow swapping to dimension names that don't exist yet. (:pull:`3636`) By `Justus Magin <https://github.com/keewis>`_. - Extend :py:class:`~core.accessor_dt.DatetimeAccessor` properties and support ``.dt`` accessor for timedeltas via :py:class:`~core.accessor_dt.TimedeltaAccessor` (:pull:`3612`) By `Anderson Banihirwe <https://github.com/andersy005>`_. - Improvements to interpolating along time axes (:issue:`3641`, :pull:`3631`). By `David Huard <https://github.com/huard>`_. - Support :py:class:`CFTimeIndex` in :py:meth:`DataArray.interpolate_na` - define 1970-01-01 as the default offset for the interpolation index for both :py:class:`pandas.DatetimeIndex` and :py:class:`CFTimeIndex`, - use microseconds in the conversion from timedelta objects to floats to avoid overflow errors. - Bug fixes: - Applying a user-defined function that adds new dimensions using :py:func:`apply_ufunc` and ``vectorize=True`` now works with ``dask > 2.0``. (:issue:`3574`, :pull:`3660`). By `Deepak Cherian <https://github.com/dcherian>`_. - Fix :py:meth:`~xarray.combine_by_coords` to allow for combining incomplete hypercubes of Datasets (:issue:`3648`). By `Ian Bolliger <https://github.com/bolliger32>`_. - Fix :py:func:`~xarray.combine_by_coords` when combining cftime coordinates which span long time intervals (:issue:`3535`). By `Spencer Clark <https://github.com/spencerkclark>`_. - Fix plotting with transposed 2D non-dimensional coordinates. (:issue:`3138`, :pull:`3441`) By `Deepak Cherian <https://github.com/dcherian>`_. - :py:meth:`plot.FacetGrid.set_titles` can now replace existing row titles of a :py:class:`~xarray.plot.FacetGrid` plot. In addition :py:class:`~xarray.plot.FacetGrid` gained two new attributes: :py:attr:`~xarray.plot.FacetGrid.col_labels` and :py:attr:`~xarray.plot.FacetGrid.row_labels` contain :py:class:`matplotlib.text.Text` handles for both column and row labels. These can be used to manually change the labels. By `Deepak Cherian <https://github.com/dcherian>`_. - Fix issue with Dask-backed datasets raising a ``KeyError`` on some computations involving :py:func:`map_blocks` (:pull:`3598`). By `Tom Augspurger <https://github.com/TomAugspurger>`_. - Ensure :py:meth:`Dataset.quantile`, :py:meth:`DataArray.quantile` issue the correct error when ``q`` is out of bounds (:issue:`3634`) by `Mathias Hauser <https://github.com/mathause>`_. - Fix regression in xarray 0.14.1 that prevented encoding times with certain ``dtype``, ``_FillValue``, and ``missing_value`` encodings (:issue:`3624`). By `Spencer Clark <https://github.com/spencerkclark>`_ - Raise an error when trying to use :py:meth:`Dataset.rename_dims` to rename to an existing name (:issue:`3438`, :pull:`3645`) By `Justus Magin <https://github.com/keewis>`_. - :py:meth:`Dataset.rename`, :py:meth:`DataArray.rename` now check for conflicts with MultiIndex level names. - :py:meth:`Dataset.merge` no longer fails when passed a :py:class:`DataArray` instead of a :py:class:`Dataset`.

Brady <https://github.com/bradyrx>`_. - Internal Changes: - Make sure dask names change when rechunking by different chunk sizes. Conversely, make sure they stay the same when rechunking by the same chunk size. (:issue:`3350`) By `Deepak Cherian <https://github.com/dcherian>`_. - 2x to 5x speed boost (on small arrays) for :py:meth:`Dataset.isel`, :py:meth:`DataArray.isel`, and :py:meth:`DataArray.__getitem__` when indexing by int, slice, list of int, scalar ndarray, or 1-dimensional ndarray.
