This is when each Discourse release line stops receiving security updates. 3 release lines are still supported — the next to reach end-of-life is Discourse 2026.4 on 30 Jun 2026. Running an end-of-life version means new vulnerabilities stay unpatched.

When does Discourse 2026.4 reach end of life?

Is Discourse end-of-life?
No — Discourse still has supported release lines (2026.1, 2026.5, 2026.4). But individual older versions are end-of-life, so what matters is the specific version you run.
