How do I see fixed bugs for a package at bugs.debian.org?

How do I see fixed bugs for a package at bugs.debian.org?  I can find open bugs from https://www.debian.org/Bugs/, but maybe something that has been fixed would give me insight.

I would like to see fixed bugs for the mailman3 package, and related packages.

I am trying to migrate from mailman2 to mailman3.  One step is to create a brand-new mailman2 list, populate it with a few emails, and then migrate that list to mailman3.  The mailman import21 seems to work, but the hyperkitty_import does not.  A search of hyperkitty_import on this list comes up empty.  My Google searches have not been helpful.  Anyhow, looking at the fixed bugs _might_ give me a clue, but I don't see how to do that.

Yes, it will probably seem obvious once I know how.

Thanks,

Ken
