Given that (as far as I'm aware) apt-listchanges just reports the changelog and NEWS entries from the various packages, the question should really be: a changelog or NEWS entry in what package, and what version of that package? In this case, the relevant package appears to be libc6, from the source package glibc. The changelog entry for glibc 2.28-5 mentions a backport of what looks to my eye like the patch which makes this change, albeit without mentioning what effect the change itself will have; to figure that out, you have to read the referenced (Debian) bug report, #877900. That patch appears to have been released upstream in glibc 2.29, which doesn't seem to have hit Debian testing yet. So I think the suggestion would have been that either the changelog or the NEWS entry from the Debian-packaged version of glibc which first included the patch which makes this change should have had a comment pointing out that the default date format for this common locale would change. > If a script is relying on the output of a program like date without > specifying either the C locale or a date format, it's almost > certainly doing something wrong--those strings are expected to > change depending on things like locale settings, and are for humans > to read, not programs.
