 - **[feature]**
   New filter function :py:func:`urlquote_plus`
 
+- **[feature]**
+  New filter functions :py:func:`None` and :py:func:`Empty`. They are
+  useful in variable interpolation context where they suppress possible
+  lookup errors (aka :py:exception:`KeyError`) and instead return with
+  :py:obj:`None` or an empty string.
