 * Add support for the ``<wbr>`` element in the sanitizer, `which indicates
  a line break opportunity <https://html.spec.whatwg.org/#the-wbr-element>`_.
  This element is allowed by default. (#395) (Thank you, Tom Most!)
 * Add support for serializing the ``<ol reversed>`` boolean attribute. (Thank
  you, Tom Most!) (#396)
 * The ``<ol reversed>`` and ``<ol start>`` attributes are now permitted by the
  sanitizer. (#321) (Thank you, Tom Most!)

 Bug fixes:

 * The sanitizer now permits ``<summary>`` tags.
 * The sanitizer now permits ``<summary>`` tags. It used to allow ``<details>``
  already. (#423)
