Kubernetes end-of-life: support & EOL dates for every release
CNCF · Infrastructure · 4 supported · 17 end-of-life · updated June 2026 · what is end-of-life? →
This is when each Kubernetes release line stops receiving security updates. 4 release lines are still supported — the next to reach end-of-life is Kubernetes 1.33 on 28 Jun 2026. Running an end-of-life version means new vulnerabilities stay unpatched.

Which Kubernetes version should I run?
The safest choice is the latest supported release, 1.36.2. If you're on an end-of-life line, plan an upgrade to a supported one before security updates stop. See Kubernetes's full security status →

End-of-life dates are easy to miss until it's too late. Monitor Kubernetes on IsItPatched and we'll email you before the release line you run stops getting security updates — free, no account needed to start.

What Kubernetes versions are still supported?
As of June 2026, these Kubernetes release lines still receive security updates: 1.36, 1.35, 1.34, 1.33. The latest supported release is 1.36.2.

When does Kubernetes 1.33 reach end of life?
Kubernetes 1.33 reaches end-of-life on 28 Jun 2026 — imminently. After that date it stops receiving security patches.
Is Kubernetes end-of-life?
No — Kubernetes still has supported release lines (1.36, 1.35, 1.34, 1.33). But individual older versions are end-of-life, so what matters is the specific version you run.
How do I know when my Kubernetes version reaches end of life?
Check the version you run on its product page, or monitor Kubernetes on IsItPatched to get an email alert before the release line you use reaches end-of-life — so you can upgrade in time.
