Thanks!

Will this be released on pip?

[TheTripleV]

Yes, it has been released.

Sweet. And will this normally skip text in

and

that would normally be displayed? or will it only skip things like <script> etc. that wouldn't normally be displayed?

This change skips all raw nodes. So for your repo, this should skip the script tags and <br /> that appeared in the description.

In general, invisible nodes, admonitions, raw nodes, and the first header of the page (if it is equivalent to the title metadata) are skipped.
