Hi, (Apologies for the delay, I didn't get a copy of that reply, which I think is because I am only uploader now not maintainer.)
Thanks - I understand now. The only things stored outside the personal space (~/.angband/) are the save files and the high score file. Older versions had private score files - it wasn't possible to have system-wide score files due to a security bug in gtk that prevented building the package with setgid. Now gtk has been deprecated upstream the package is built with setgid so that all users feature in the same high score file - but of course it started blank, because it's a new one in a new place. So I don't think either you or anyone else has actually lost anything - but you're right that it's worth a mention in NEWS.Debian in case people want to go hunting for their old private high score file. Best Chris
