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.

v0.8.1

What's Changed

• Change import to support shapely 1 and 2. by @huard in #298

Full Changelog: v0.8...v0.8.1

v0.8

This release of xESMF improves support for parallelization with dask: weights can now be computed in parallel, and those weights can be applied over chunks spanning the horizontal grid dimensions. Previously, computing weights in parallel was only possible using MPI, and datasets could only be chunked over non-spatial dimensions.

These new features are the outcome of Charles Gauthier' internship at Ouranos during the summer of 2023. Thanks to Charles for his hard work and sharp analysis, which led to a permanent position at Ouranos!
