Now that @stephdl started to develop a yum-cron configuration package, I’d like to bump also this topic, in the hope of including this feature in the next ISO release.
I’d like to add a new checkbox/action to the items under “Software Center > Installed” tab.
Such feature would have been useful, for instance, during the past release of Nextcloud 11, to exclude an installed module from automatic updates. We have to find a way to stop updating (some) module dependencies, though.
