I'm afraid it really does happen with 4.1:
niko@niko-desktop:~$ cat /var/log/dpkg.log | grep apt-listchanges | tail -3 2023-10-10 11:28:51 status unpacked apt-listchanges:all 4.1 2023-10-10 11:28:51 status half-configured apt-listchanges:all 4.1 2023-10-10 11:28:52 status installed apt-listchanges:all 4.1 And the issue is still there. It happened e.g. with today's chromium update.
