Hm, can they be accessed before actually doing the update? Because Synaptic always tells me
This change is not coming from a source that supports changelogs.
Failed to fetch the changelog for pureos-gnome
URI was: http://repo.puri.sm/pool/main/p/pureos-meta/pureos-gnome_0.9.5_amd64.changelog
But to re-iterate: I would not consider a dump of all upstream changes helpful. I would consider it helpful if the release notes would focus on notable changes, e.g. security, changes Purism was working on, or important packages.
