About HAProxy 3.1

HAProxy 3.1 recently reached end of life on January 1, 2026. This means it no longer receives security patches or bug fixes from the maintainers. If you are still on this version, now is the time to finalize your upgrade plan before the gap between your version and the current release grows wider.

The recommended upgrade target is HAProxy 3.2 LTS. You are 2 major versions behind, so review the changelog for each version in between to catch any breaking changes. A staged upgrade through each major version is often safer than jumping directly.
