+``reverse``
+===========
+
+.. versionadded:: 1.6
+    Support for strings has been added in Twig 1.6.
+
+The ``reverse`` filter reverses a sequence, a mapping, or a string:
+
+.. code-block:: jinja
+
+    {% for user in users|reverse %}
+        ...
+    {% endfor %}
+
+    {{ '1234'|reverse }}
+
+    {# outputs 4321 #}
+
+.. tip::
+
+    For sequences and mappings, numeric keys are not preserved. To reverse
+    them as well, pass ``true`` as an argument to the ``reverse`` filter:
+
+    .. code-block:: jinja
+
+        {% for key, value in {1: "a", 2: "b", 3: "c"}|reverse %}
+            {{ key }}: {{ value }}
+        {%- endfor %}
+
+        {# output: 0: c    1: b    2: a #}
+
+        {% for key, value in {1: "a", 2: "b", 3: "c"}|reverse(true) %}
+            {{ key }}: {{ value }}
+        {%- endfor %}
+
+        {# output: 3: c    2: b    1: a #}
+
+.. note::
+
+    It also works with objects implementing the `Traversable`_ interface.
+
+Arguments
+---------
+
+ * ``preserve_keys``: Preserve keys when reversing a mapping or a sequence.
