 * Calling a ``sdba.map_blocks``-wrapped function with data chunked along the reduced dimensions will raise an error. This forbids chunking the trained dataset along the distribution dimensions, for example. (:issue:`1481`, :pull:`1482`).
 * Optimization of indicators ``huglin_index`` and ``biologically_effective_degree_days`` when used with dask and flox. As a side effect, the indice functions (i.e. under ``xc.indices``) no longer mask incomplete periods. The indicators' output is unchanged under the default "check_missing" setting (:issue:`1494`, :pull:`1495`).
 * Fixed ``xclim.indices.run_length.lazy_indexing`` which would sometimes trigger the loading of auxiliary coordinates. (:issue:`1483`, :pull:`1484`).
+* Fixed a bug in the `pytest` configuration that could prevent testing data caching from occurring in systems where the platform-dependent cache directory is not found in the user's home. (:issue:`1468`, :pull:`1473`).
