 * #1884, #1885: plug-in html themes cannot inherit another plug-in theme. Thanks to
   Suzumizaki.
+* #1818: `sphinx.ext.todo` directive generates broken html class attribute as
+  'admonition-' when :confval:`language` is specified with non-ASCII linguistic area like
+  'ru' or 'ja'. To fix this, now ``todo`` directive can use ```:class:`` option.

+* #2127: MecabBinder for html searching feature doesn't work with Python 3.
