+v0.9.0 (02 June 2025)
+---------------------
+
+This release introduces key functional and performance enhancements
+across regridding, averaging, and coordinate handling workflows. Users
+can now output regridding weights and infer vertical target data,
+improving flexibility in vertical and horizontal transformations. Time
+frequency inference logic is more robust through median delta
+computation, and new options for ``skipna`` handling and spatial weight
+thresholds support more accurate and configurable statistical
+operations. Additional improvements to coordinate handling enable
+support for curvilinear grids. The release also includes critical bug
+fixes, expanded documentation, and updated compatibility for modern
+Python environments by dropping Python 3.9 and adding compatibility with
+Python 3.13.
