Drupal 8 & 9: Introducing new "Update Manager Advanced" module
This module modifies the Drupal "Available updates" email report to include the information normally shown at
/admin/reports/updates/update, with links to the module updates and their release notes.
It can be helpful, for example, in case, if you received the mail and see that only one module was updated and this module uses on the admin interface only and nothing critical for the visitors and updating can wait. So you shouldn't spend time in opening the site for checking.
