Where does the EOL data for MediaWiki come from?

From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the MediaWiki data is as of 26/08/2026. In case of doubt the vendor's own lifecycle page applies — patchletter deliberately stores no vendor full texts.
