  2. Triggers when a User is registered / removed / or changed its role.

    Again you can change the default message and include the :username: tag to include the new username. Some extra tags can be used like :old_role: and :new_role: when a user roles is changed.
  3. Triggers when a new theme is installed or when the theme has an update available. When an option is checked you will get this Screen

You can use the :post_type:  tag to specify the post type (product, menu item etc), the :title: of your post and the status tags :old_status: and :new_status: to send the status changed. You can include the :current_user: tag to actually send the name of the user that made this change.
