   The author date of the commit, in its original time zone, formatted as

+If the commit is a fix for the mentioned commit, consider using a ``Fixes:``

+If relevant, add the first release tag of CMake containing the commit after
+the ``<date>``, i.e., ``commit <shorthash> (<subject>, <date>, <tag>)``.

 Alternatively, the full commit ``<hash>`` may be used.
