Question 1

What happens when Duckdb reaches end of life?

Accepted Answer

When Duckdb reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 4 Duckdb versions are already EOL. The latest supported version is Duckdb 1.5. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Duckdb 1.5 still supported?

Accepted Answer

Yes. Duckdb 1.5 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Duckdb releases and their exact end-of-life dates.

Question 3

Is it safe to use Duckdb after end of life?

Accepted Answer

No. Running Duckdb 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 Duckdb release.

Question 4

How to upgrade from Duckdb 1.3 to Duckdb 1.x?

Accepted Answer

To upgrade Duckdb from 1.3 to 1.5: (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 Duckdb LTS version?

Accepted Answer

Duckdb 1.4 is the current Long Term Support release, maintained until September 16, 2026. LTS versions are recommended for production deployments that prioritize long-term stability over new features. Plan your upgrades to coincide with LTS releases whenever possible.

Question 6
