The updates notification icon in system tray isn't shown any more. Howver, the discovernotifier plasmoid works ok if I add it to the panel. Reproducible: Always
After comparing 5.8.0 with the master branch in git, it seems that the problem is caused by the line X-KDE-ParentApp=org.kde.discover.desktop in the file /usr/share/plasma/plasmoids/org.kde.discovernotifier/metadata.desktop
Maybe this problem is also related to the older bugreport: https://bugs.kde.org/show_bug.cgi?id=347496 Although before 5.8 it worked for me in Neon User edition.

Not sure about the older bug, but the reason for this bug is the line X-KDE-ParentApp=org.kde.discover.desktop in the file /usr/share/plasma/plasmoids/org.kde.discovernotifier/metadata.desktop If you remove this line, the icon is shown again. It is already fixed in the master branch in git but I believe it is a good idea to be fixed also in 5.8 branch as it is supposed to be an LTS release.
Yea, you're right. It was already fixed by Aleix Pol and I assume it will land with 5.8.1. Aleix pushed it to 5.8 branch. You can close this bug report as duplicate of https://bugs.kde.org/show_bug.cgi?id=369644.
