 the contributor of the change is expected to make good effort to migrate the
 upstream platforms to the new interface.
 
-The `Release information`_ documents the deprecated interfaces and the intended
-release after which it will be removed. When an interface is deprecated, the
-page must be updated to indicate the release after which the interface will be
-removed. This must be at least 1 full release cycle in future. For non-trivial
-interface changes, a `tf-issue`_ should be posted to notify platforms that they
-should migrate away from the deprecated interfaces. Platforms are expected to
-migrate before the removal of the deprecated interface.
+The deprecated interfaces are listed inside `Release information`_ as well as
+the release after which each one will be removed. When an interface is
+deprecated, the page must be updated to indicate the release after which the
+interface will be removed. This must be at least 1 full release cycle in future.
+For non-trivial interface changes, an email should be sent out to the `TF-A
+public mailing list`_ to notify platforms that they should migrate away from the
+deprecated interfaces. Platforms are expected to migrate before the removal of
+the deprecated interface.
