does somebody know how to check which apps will be not tested or break for a next upgrade?
My own solution would be to get all apps via occ app:list and afterwards crawl the app store website to check the status for the given release. But before I start to code I would like to check if there is already a good solution for this.
you understood me wrongly here - this is displayed on the admin settings page where you would start the update, so at the place where it notifies you of a new available version. There is also states e.g. that some of your apps are lacking compatible versions for the ugrade.
