 * Add middleware that cleans up the response string after it has been
   served, stabilizes memory usage for large requests #1847
 
-* The ``vocabulary_show`` API call no longer returns the ``packages`` key -
-  i.e. datasets that use the vocabulary. ``tag_show`` API call now supports
-  vocabularies, so that you can get the datasets using a vocabulary tag. In
-  addition ``tag_show`` has an option not ``include_datasets``, which gives

+  ``tag_show`` now has an ``include_datasets`` option and has been extended
