* Get canonical URL from environment variable when building on
Read the Docs. :pr:`117`
* New version warning banner. Use JavaScript to query PyPI when
viewing a page, rather than baking the warning into the
build. New builds of old versions are no longer required for
the banner to be correct. :pr:`117`
* Generate 404 page using the sphinx-notfound-page extension.
This fixes the URLs when the page is hosted so that it loads
the CSS. :issue:`34`
* Remove handling for singlehtml_sidebars config which predated
Sphinx's support. :pr:`119`
* Remove "babel" and "platter" theme variants which were
undocumented and did not appear to be used by the relevant
projects. :pr:`120`
