Bumps xarray from 2026.4.0 to 2026.9.0.

Release notes

Sourced from xarray's releases.

v2026.09.0

This release adds read support for Zarr V3 rectilinear (variable-sized) chunks, Arrow PyCapsule export for :py:class:DataArray, a new :py:meth:DataArray.plot.lines plotting method, :py:class:DataTree support in :py:func:apply_ufunc, and flox-accelerated groupby medians. Bottleneck is now disabled by default, the remaining zarr-python 2 compatibility code has been removed, and the minimum h5netcdf version is now 1.8. It also includes many bug fixes.

This is the last xarray release that will support Python 3.11. Future releases will require Python 3.12 or later.

Thanks to the 45 contributors to this release: ANIRUDDHA ADAK, Ahmet Kamer Çivi, Albert Yau, Andrew Scherer, Anirban Mandal, Aryan Singh K., Asish Kumar, Chandan P, Charles Turner, Deepak Cherian, Devraj Pal, Dipak Chaudhari, Eltsefon Mark, Evan Lyall, Illviljan, Joe Hamman, Johnson K C, Jules Chéron, Justus Magin, Kropiunig, Marcus Campbell, Mark Harfouche, Matt Van Horn, Matthew Rocklin, Matthias Schabel, Michael Niklas, Nick Hodgskin, Patrick N.

Your project could benefit from a custom flavor, which would allow you to run only the linters you need, and thus improve runtime performances. (Skip this info by defining FLAVOR_SUGGESTIONS: false)
