I've successfuly upgrade servers with mailman3 lists from FreeBSD 12.3 with python 3.7 to FreeBSD 13.1 with python 3.9

Thank you for letting us know, I'm sure other FreeBSD users will find this information useful.

I had to edit again /usr/local/lib/python3.9/site-packages/mistune/scanner.py and add this two lines (this is a little bit annoying) from mistune.util import escape_html from mistune.util import escape_url

We're sorry about that. These things slip through the cracks sometimes, but I believe with your help this has already been fixed for the next release of Mailman.
