- Deprecations:
- Following pandas, the `closed` parameters of :py:func:`cftime_range` and
:py:func:`date_range` are deprecated in favor of the `inclusive` parameters,
and will be removed in a future version of xarray (:issue:`6985`:,
:pull:`7373`).
- Bug fixes:
- :py:func:`xarray.concat` can now concatenate variables present in some datasets but
not others (:issue:`508`, :pull:`7400`).
- Handle ``keep_attrs`` option in binary operators of :py:meth:`Dataset` (:issue:`7390`, :pull:`7391`).
- Improve error message when using dask in :py:func:`apply_ufunc` with ``output_sizes`` not supplied. (:pull:`7509`)
- :py:func:`xarray.Dataset.to_zarr` now drops variable encodings that have been added by xarray during reading
a dataset. (:issue:`7129`, :pull:`7500`).
- Documentation:
- Mention the `flox package `_ in GroupBy documentation and docstrings.
- update to version 2023.01.0:
- This release includes a number of bug fixes. Thanks to the 14 contributors to this release:
- Aron Gergely, Benoit Bovy, Deepak Cherian, Ian Carroll, Illviljan, Joe Hamman, Justus Magin, Mark Harfouche,:
- Matthew Roeschke, Paige Martin, Pierre, Sam Levang, Tom White, stefank0.:
- Breaking changes:
- :py:meth:`CFTimeIndex.get_loc` has removed the ``method`` and ``tolerance`` keyword arguments.
Use ``.get_indexer([key], method=..., tolerance=...)`` instead (:pull:`7361`).
- Bug fixes:
- Avoid in-memory broadcasting when converting to a dask dataframe
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`,
and :py:meth:`Variable.pad` (:pull:`7267`).
- Fixed performance regression in alignment between indexed and non-indexed objects
of the same shape (:pull:`7382`).
- Preserve original dtype on accessing MultiIndex levels (:issue:`7250`,
:pull:`7393`).
- Internal Changes:
- Add the pre-commit hook `absolufy-imports` to convert relative xarray imports to
absolute imports (:pull:`7204`, :pull:`7370`).
