Check mediawiki-version

Overview

Checks the installed MediaWiki version against the endoflife.date API and alerts if the version is end-of-life or if newer major, minor, or patch releases are available. By default, alerts 30 days before the official EOL date. The offset is configurable.

Data Collection:

  • Reads the installed MediaWiki version from the Defines.php file (default: /var/www/html/wiki/includes/Defines.php)

  • Compares the installed version against the endoflife.date API to determine EOL status and available updates

  • Uses SQLite to cache API responses between runs
