Running an end-of-life etcd version?

OSSeva keeps end-of-life etcd patched with signed builds and backported CVE fixes, documents it for your auditor, and can run it for you, so the upgrade happens on your schedule rather than the project’s.

etcd end of life: common questions

What is the latest etcd version?

3.7.2, released 22 Sept 2026, on the 3.7 line. Other supported lines: 3.6 and 3.5.

When is the next etcd end of life?

etcd 3.5 reaches the end of security support on 8 Jul 2027. After that date the project stops shipping security fixes for 3.5, and CVEs disclosed later stay unpatched upstream.

Which etcd versions are still supported?

3.7, 3.6 and 3.5 (until 8 Jul 2027). Every other line has reached end of life, per the dates in the table above.

Can I get security patches for an end-of-life etcd version?

Yes. OSSeva ships signed builds with backported CVE fixes for etcd 3.4 and 3.3 after upstream support ends, on the Patch, Assure and Operate tiers, so you can stay on the version you run while you plan the upgrade.
