🚀 Release v2.1.1 (#53)
Markdown's behavior pre-v3 was to automatically append mdx_ to strings
that acted as references to third-party extensions. Starting in Markdown
v3, this behavior has been removed. In v2.1.0 of this package, we
therefore lost the ability to refer to subscript (forcing developers
to switch to mdx_subscript) if referring to the extension by string
(but only in Markdown v3).
This release re-enables behavior seen on older versions of Markdown.

🚀 Update package; Support for Python-Markdown 3.0 (#52)
On top of supporting Python-Markdown v3, this is a long-overdue re-haul
of some of the package infrastructure. Notably, nose and unittest tests
