 * The ``tower_credential`` module originally required the ``ssh_key_data`` to be the path to a ssh_key_file.
   In order to work like Tower/AWX, ``ssh_key_data`` now contains the content of the file.
   The previous behavior can be achieved with ``lookup('file', '/path/to/file')``.
+* The ``win_scheduled_task`` module deprecated support for specifying a trigger repetition as a list and this format
+  will be removed in Ansible 2.12. Instead specify the repetition as a dictionary value.
