Advisory for Icinga 2 v2.7 Update and Mail Notification Scripts

You may have recognized that Icinga 2 v2.7 introduced new notification scripts. These came out of the interest we’ve seen in community scripts. So we decided to bring these scripts into Icinga 2 v2.7 making them available for everyone.
The scripts were designed to act as drop-in replacement with old 2.6.x configuration. Unfortunately several environment variables had been renamed. Testers didn’t catch this, so here is a summary for you what to fix and change in your scripts during an upgrade.
