  * The template loader now raises a `TemplateNotFound` error when a previously
    cached template is removed or renamed, where it previously was passing up
    an `OSError`.
+ * The Genshi I18n filter can be configured to only extract messages found in
+   `gettext` function calls, ignoring any text nodes and attribute values.

 .. _`text templates`: text-templates.html
 
 ``encoding``
-------------------
+------------
 The encoding of the template file. This is only used for text templates. The
 default is to assume “utf-8”.
 
 ``include_attrs``
-------------------
+-----------------
 Comma-separated list of attribute names that should be considered to have 
 localizable values. Only used for markup templates.
 
-``include_tags``
-------------------
+``ignore_tags``
+---------------
 Comma-separated list of tag names that should be ignored. Only used for markup 
 templates.
 
+``extract_text``
+----------------
+Whether text outside explicit ``gettext`` function calls should be extracted.
+By default, any text nodes not inside ignored tags, and values of attribute in
+the ``include_attrs`` list are extracted. If this option is disabled, only 
+strings in ``gettext`` function calls are extracted.
+
+.. note:: If you disable this option, it's not necessary to add the translation
+          filter as described above. You only need to make sure that the
+          template has access to the ``gettext`` functions it uses.
