+Version 1.4.0 (2026/07/24)
+--------------------------
+
+* Fixed: use strict index hash for caching results
+  with ``audinterface.Process.process_index()``
+  and ``audinterface.Feature.process_index()``.
+  Before, the same cache was used for indices
+  that only differed in their order,
+  and the returned results could be in an incorrect order
+  when using the cache.
+  This means that caches that were created with an older version
+  will not be reused with this version.
