Question 1

What happens when Apache Celeborn reaches end of life?

Accepted Answer

When Apache Celeborn reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 3 Apache Celeborn versions are already EOL. The latest supported version is Apache Celeborn 0.7. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Apache Celeborn 0.7 still supported?

Accepted Answer

Yes. Apache Celeborn 0.7 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Apache Celeborn releases and their exact end-of-life dates.

Question 3

Is it safe to use Apache Celeborn after end of life?

Accepted Answer

No. Running Apache Celeborn 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 Apache Celeborn release.

Question 4

How to upgrade from Apache Celeborn 0.6 to Apache Celeborn 0.x?

Accepted Answer

To upgrade Apache Celeborn from 0.6 to 0.7, 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 Apache Celeborn LTS version?

Accepted Answer

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

Question 6

How long does Apache Celeborn support each version?

Accepted Answer

On average, Apache Celeborn supports each release for approximately 13 months (~1.1 years).  The exact EOL date for each version is listed in the table above.
