xarray is now specified as a lower-bound-only constraint (">=") which means users installing from sdist/wheel can end up with arbitrarily newer xarray releases than the one validated in this repo (the lock already resolves to 2026.4.0). If you want the update but still want predictable installs, consider using a compatible range (e.g., caret) or adding an explicit upper bound.

Suggested change

	xarray = ">=2025.1.1"
	xarray = ">=2025.1.1,<2027.0.0"

deptry = ">0.21.2" excludes exactly 0.21.2. If the intent is simply to relax the previous ^0.21.2 cap so newer deptry versions are allowed, prefer >=0.21.2 (or another bounded range) to avoid an unnecessary/accidental gap.

Suggested change

	deptry = ">0.21.2"
	deptry = ">=0.21.2"
