Question 1

What happens when Contao reaches end of life?

Accepted Answer

When Contao reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 13 Contao versions are already EOL. The latest supported version is Contao 5.7, maintained until February 14, 2030. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Contao 5.7 still supported?

Accepted Answer

Yes. Contao 5.7 is actively supported until February 14, 2030. It receives security patches and bug fixes. Check the version table above for the full list of supported Contao releases and their exact end-of-life dates.

Question 3

Is it safe to use Contao after end of life?

Accepted Answer

No. Running Contao 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 Contao release.

Question 4

How to upgrade from Contao 5.6 to Contao 5.x?

Accepted Answer

To upgrade Contao from 5.6 to 5.7: (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 Contao LTS version?

Accepted Answer

Contao 5.7 is the current Long Term Support release, maintained until February 14, 2030. 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

How long does Contao support each version?

Accepted Answer

On average, Contao supports each release for approximately 24 months (~2 years). LTS releases like Contao 5.7 have extended support windows — maintained until February 14, 2030. The exact EOL date for each version is listed in the table above.
