===================== ========= =======
Package Old New
===================== ========= =======
boto3 1.28 1.29
dask-core 2023.9 2023.11
distributed 2023.9 2023.11
h5netcdf 1.2 1.3
numbagg 0.2.1 0.6
typing_extensions 4.7 4.8
===================== ========= =======
- Deprecations:
- Grouping by a chunked array (e.g. dask or cubed) currently eagerly loads that variable in to
memory. This behaviour is deprecated. If eager loading was intended, please load such arrays
manually using ``.load()`` or ``.compute()``. Else pass ``eagerly_compute_group=False``, and
provide expected group labels using the ``labels`` kwarg to a grouper object such as
:py:class:`grouper.UniqueGrouper` or :py:class:`grouper.BinGrouper`.
- Bug fixes:
- Fix inadvertent deep-copying of child data in DataTree (:issue:`9683`,
:pull:`9684`).
By `Stephan Hoyer <https://github.com/shoyer>`_.
- Avoid including parent groups when writing DataTree subgroups to Zarr or
netCDF (:pull:`9682`).
By `Stephan Hoyer <https://github.com/shoyer>`_.
- Fix regression in the interoperability of :py:meth:`DataArray.polyfit` and :py:meth:`xr.polyval` for date-time coordinates. (:pull:`9691`).
By `Pascal Bourgault <https://github.com/aulemahal>`_.
- Fix CF decoding of ``grid_mapping`` to allow all possible formats, add tests (:issue:`9761`, :pull:`9765`).
By `Kai Mühlbauer <https://github.com/kmuehlbauer>`_.
- Add ``User-Agent`` to request-headers when retrieving tutorial data (:issue:`9774`, :pull:`9782`)
By `Kai Mühlbauer <https://github.com/kmuehlbauer>`_.
- Documentation:
- Mention attribute peculiarities in docs/docstrings (:issue:`4798`, :pull:`9700`).
By `Kai Mühlbauer <https://github.com/kmuehlbauer>`_.
- Internal Changes:
- ``persist`` methods now route through the :py:class:`xr.core.parallelcompat.ChunkManagerEntrypoint` (:pull:`9682`).
By `Sam Levang <https://github.com/slevang>`_.
- update to version 2024.10.0:

decode times encoded with small integer dtype values (e.g. ``np.int32``) in
environments with NumPy 2.0 or greater without needing to fall back to cftime
(:pull:`9518`). By `Spencer Clark <https://github.com/spencerkclark>`_.
