+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. deprecated:: 12.0.0
+
+``ImageCms.ImageCmsProfile.product_name`` and the corresponding
+``.product_info`` attributes have been deprecated, and will be removed in
+Pillow 13 (2026-10-15). These attributes can be accessed on the ``.profile``
+attribute of ``ImageCmsProfile`` instead.
+
+Note that ``.product_name`` and ``.product_info`` have been set to ``None`` on
+``ImageCmsProfile`` since Pillow 2.3.0 (2014-01-01), so any working code that
+makes use of this data will already access it on ``.profile``.
