+``constant``
+============
+
+.. versionadded: 1.13.1
+    constant now accepts object instances as the second argument.
+
+``constant`` checks if a variable has the exact same value as a constant. You
+can use either global constants or class constants:
+
+.. code-block:: jinja
+
+    {% if post.status is constant('Post::PUBLISHED') %}
+        the status attribute is exactly the same as Post::PUBLISHED
+    {% endif %}
+
+You can test constants from object instances as well:
+
+.. code-block:: jinja
+
+    {% if post.status is constant('PUBLISHED', post) %}
+        the status attribute is exactly the same as Post::PUBLISHED
+    {% endif %}

+``defined``
+===========
+
+``defined`` checks if a variable is defined in the current context. This is very
+useful if you use the ``strict_variables`` option:
+
+.. code-block:: jinja
+
+    {# defined works with variable names #}
+    {% if foo is defined %}
+        ...
+    {% endif %}
+
+    {# and attributes on variables names #}
+    {% if foo.bar is defined %}
+        ...
+    {% endif %}
+
+    {% if foo['bar'] is defined %}
+        ...
+    {% endif %}
+
+When using the ``defined`` test on an expression that uses variables in some
+method calls, be sure that they are all defined first:
+
+.. code-block:: jinja
+
+    {% if var is defined and foo.method(var) is defined %}
+        ...
+    {% endif %}
