[dependabot]

Bumps xarray from 2025.10.1 to 2026.7.0.

Release notes

Sourced from xarray's releases.

v2026.07.0

This release adds support for Dask's query-optimizing expression arrays, along with new day_of_week and day_of_year datetime accessor attributes. It also includes a number of bug fixes, notably for a performance regression in :py:meth:Coordinates.to_index, Zarr fill_value round-tripping, and excessive memory use in drop_encoding.
