Hello!

I've just imported 10.3.30 into our Debian packaging repositories and
so far I have not seen any regressions[1]. I expect us to be able to
ship this with the next stable Debian Buster release.

Faustin: Do you want to help out and update the debian/changelog,
adding appropriate "(Closes: #nnnnnn)" items so the changelog will
tell both users and Debian release managers why the update is
important?
