* 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)
