+``max``
+=======
+
+.. versionadded:: 1.15
+    The ``max`` function was added in Twig 1.15.
+
+``max`` returns the biggest value of a sequence or a set of values:
+
+.. code-block:: jinja
+
+    {{ max(1, 3, 2) }}
+    {{ max([1, 3, 2]) }}
+
+    # When called with a mapping, max ignores keys and only compares values.
