The doc for "How are cPAddons updated?" says (at All Documentation)
Is this right? I don't see the automatic option at "Manage cPAddons" in my WHM 11.30. Maybe my host has configged it out or something? Is there a cronjob?You can manage specific configuration options for your cPAddons using the Manage cPAddons feature located at Main >> cPanel >> Manage cPAddons in your WHM interface. This feature will allow you to choose which cPAddons you wish to update automatically.
These cPAddons are updated by a cronjob that runs nightly. This cronjob updates the cPAddon repository for the entire server.
