 1.4.5 (in development)
 ----------------------
 
-Features:
+Version 1.4.5 adds some oft-requested features. When you're importing files,
+you can now manually set fields on the new music. Date queries have gotten
+much more powerful: you can write precise queries down to the second, and we
+now have *relative* queries like ``-1w``, which means *one week ago*.

+Here are the new features:
 
 * You can now set fields to certain values during :ref:`import-cmd`, using
   either a ``--set field=value`` command-line flag or a new :ref:`set_fields`
   configuration option under the `importer` section.
