Kubernetes end of life: end of support by version
CNCF · Virtualization & Backup
For Kubernetes by CNCF, patchletter knows 12 support cycles. 8 of them have already ended and receive no more security updates. The next support window closes on 27/10/2026, that is in 16 days. The current version of Kubernetes is 1.37.1. The cycles come from the open endoflife.date project, last reconciled on 30/09/2026.
When does support end for which Kubernetes 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 Kubernetes come from?
From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the Kubernetes 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.
