Question 1

What happens when External Dns reaches end of life?

Accepted Answer

When External Dns reaches end of life, it stops receiving security patches, bug fixes, and new features.  The latest supported version is External Dns 0. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is External Dns 0 still supported?

Accepted Answer

Yes. External Dns 0 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported External Dns releases and their exact end-of-life dates.

Question 3

Is it safe to use External Dns after end of life?

Accepted Answer

No. Running External Dns 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 External Dns release.

Question 4

How to upgrade from External Dns to External Dns 0.x?

Accepted Answer

To upgrade External Dns to the latest version, start by reviewing the official migration guide for breaking changes and deprecated APIs. Update any dependencies that pin to a specific major version, then test your application against the new release in a staging environment. Run your full test suite before deploying, and always prepare a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before your current version reaches end of life.

Question 5

When is the next External Dns LTS version?

Accepted Answer

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

Question 6

How long does External Dns support each version?

Accepted Answer

Support duration varies by release. Check the version table above for the exact EOL date of each External Dns release, or refer to the official External Dns support lifecycle documentation.
