v0.9.2 - Third time's a charm

A CI bug was found that was at the source of the non-detection of many issues happenning in the conda-forge builds.

This release drops support for Python < 3.11. xESMF aims to preserve support for older python and ESMF version as long as possible with its reduced maintaining team. The most recent windows release of ESMF is currently 8.4.2 and new versions of xESMF will support it as long as it is not updated. All fixes in :pull:463, by Pascal Bourgault <https://github.com/aulemahal>_.

• Rewrote xe.smm.gen_mask_from_weights to remove scipy-dependent code.
• Fix the CI reenable testing with previous python versions.
• Avoid a SpatialAverager bug that happens when polygon segments have a length of exactly 1 on ESMF 8.4.2. The bug is not actually fixed in xESMF, but "segmentizing" the polygons with 0.99 seems to fix the issue.

v0.9.1

What's Changed

• Rewrote xe.smm.add_nans_to_weight (called when unmapped_to_nan is True)to remove scipy-dependent code, which also resulted in a significant (>=4x) speedup of that step (:pull:461).
• Fix some name collision issues in the parallel regridder initialisation (:pull:461).

v0.9

What's Changed

• Fixes for the documentation by @aulemahal in #435
• Enable the vector_regrid flag via the backend by @billsacks in #436
• Skip test for cf xarray 0.10.8 - Fix cf_grid_2d by @aulemahal in #453
• Enabling target mask for LocStream input by @sol1105 in #445
• Add option to remove source cell contributions post-weight generation by @sol1105 in #444
• Accept mask in X, Y order by @aulemahal in #457
• Add input/output dims as kwargs to regridder by @agmeyer4 in #455

New Contributors

• @billsacks made their first contribution in #436
• @agmeyer4 made their first contribution in #455

Full Changelog: v0.8.10...v0.9

v0.8.10

Patch release to fix a bug introduced in the last version.

What's Changed

• Fix passing grid as dictionary by @aulemahal in #429

Full Changelog: v0.8.9...v0.8.10

v0.8.9

A patch release that fixes a coordinates issue and tries (again) to fix the memory leak issue.

What's Changed

• Do not store grids, destroy them after usage by @aulemahal in #402
• Do not add scalar coords from the target grid to the regridding output by @aulemahal in #418

Full Changelog: v0.8.8...v0.8.9

v0.8.8

What's changed

• Fix ESMpy memory issues by explictly freeing the Grid memory upon garbage collection of Regridder objects.
• Address deprecation for xarray 2024.10 in the parallel weight generation.
• Address an upcoming change in sparse 0.16 where COO fill values will distinguish between 0.0 and -0.0. This issue would affect spatial averaging over polygons with holes.
• The conda package will now avoid installing ESMpy 8.4 to avoid importlib metadata bugs. See this issue, or this one.
