Package: apt-listchanges Version: 3.20 Severity: wishlist Man page says 'The groups are sorted by the urgency of the most urgent change, and than by the package name.'
Alas, that looks like A B C A B A B to the user. So perhaps add ------urgency=high: A B C ------urgency=medium: A B ------urgency=low: A B separators, so it would all make sense.
