Question 1

What happens when Metallb reaches end of life?

Accepted Answer

When Metallb reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 3 Metallb versions are already EOL. The latest supported version is Metallb 0.16. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Metallb 0.16 still supported?

Accepted Answer

Yes. Metallb 0.16 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Metallb releases and their exact end-of-life dates.

Question 3

Is it safe to use Metallb after end of life?

Accepted Answer

No. Running Metallb after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Metallb release.

Question 4

How to upgrade from Metallb 0.15 to Metallb 0.x?

Accepted Answer

To upgrade Metallb from 0.15 to 0.16: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Metallb LTS version?

Accepted Answer

Not all Metallb releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Metallb release policy for information on upcoming long-term support versions.

Question 6

How long does Metallb support each version?

Accepted Answer

On average, Metallb supports each release for approximately 16 months (~1.3 years).  The exact EOL date for each version is listed in the table above.
