I usually check all messages at package update looking for errors, warnings and of course the announcement of new versions of config files, which usually are marked
.pacnew when the original file has been changed. Since I tweek my system a lot, adding things to or deleting from config files it is important to apply the changes made by the maintainers. Unfortunately these
.pacnew files seem not to be announced anymore during the update process. At least I did not see any announcement during the last months, but encountered quite a few new ones on my system. One example
/etc/libreoffice/sofficerc.pacnew dating from December 28th 2918. BTW, this and
/etc/libreoffice/bootstraprc.pacnew I had not even touched before.
I would appreciate to be notices about new versions of configuration or other files during the update process of packages, if they end up in a
.pacnew file in order to merge them with the changed ones.
