Question 1

What happens when Argo Workflows reaches end of life?

Accepted Answer

When Argo Workflows reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 4 Argo Workflows versions are already EOL. The latest supported version is Argo Workflows 4.0. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Argo Workflows 4.0 still supported?

Accepted Answer

Yes. Argo Workflows 4.0 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Argo Workflows releases and their exact end-of-life dates.

Question 3

Is it safe to use Argo Workflows after end of life?

Accepted Answer

No. Running Argo Workflows 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 Argo Workflows release.

Question 4

How to upgrade from Argo Workflows 3.6 to Argo Workflows 4.x?

Accepted Answer

To upgrade Argo Workflows from 3.6 to 4.0: (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 Argo Workflows LTS version?

Accepted Answer

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

Question 6

How long does Argo Workflows support each version?

Accepted Answer

On average, Argo Workflows supports each release for approximately 21 months (~1.8 years).  The exact EOL date for each version is listed in the table above.
