+release_summary: |-
+  Feature and bugfix release.
+
+  This release adds support for the `new Hetzner API for the storage box modules
+  <https://docs.hetzner.cloud/changelog#2025-06-25-new-api-for-storage-boxes>`__.
+  You need to use ``hetzner_token`` instead of ``hetzner_user``/``hetzner_password``
+  to use the new API. Please note that the old API will be sunset on July 30th, 2025;
+  the modules will then stop working if you do not provide ``hetzner_token`` and stop
+  providing ``hetzner_user``/``hetzner_password``.
