+xskillscore v0.0.28 (2025-01-19)
+--------------------------------
+
+Bug Fixes
+~~~~~~~~~
+- Fixed a bug introduced in v0.0.27 where `numpy` v1.x support was broken for some
+  algorithms. (:pr:`431`) `Trevor James Smith`_.
+- Removed all `numpy.atleast_1d()` calls that were causing numerical differences in
+  p-value calculations with `numpy` v2.x and fixed several doctest expected outputs.
+  (:pr:`440`) `Aaron Spring`_.
+
+Internal Changes
+~~~~~~~~~~~~~~~~
+- Pinned `numpy` below v2.4 due to breaking API changes. (:pr:`441`) `Trevor James Smith`_
+- Adjusted tests to adapt to new `xarray` attributes preservation
+  behaviour. (:pr:`441`) `Trevor James Smith`_
