When does support end for which NetBSD version?
A cycle is a maintained version line. Where a date is given, support ends on that day — after it the vendor ships no more security updates for that line.

Where does the EOL data for NetBSD come from?
From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the NetBSD data is as of 30/09/2026. In case of doubt the vendor's own lifecycle page applies — patchletter deliberately stores no vendor full texts.
