This information is available at http://articlemetrics.github.io/status/:
We can show the same information in the Lagotto admin dashboard, pulling the list of public servers from http://lagotto.io/metadata.json. This file also contains the version number and date of the latest release, so that we can notify users in the admin dashboard if their Lagotto software is outdated.
We can only list servers running at least version 3.4 of the Lagotto software, as we use the
/heartbeat URL for this.
Since the Lagotto 3.7 release the software will check for the latest release via the Github releases API and will display a reminder to upgrade on the status page.
