Question 1

What happens when Steamos reaches end of life?

Accepted Answer

When Steamos reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 2 Steamos versions are already EOL. The latest supported version is Steamos 3. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Steamos 3 still supported?

Accepted Answer

Yes. Steamos 3 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Steamos releases and their exact end-of-life dates.

Question 3

Is it safe to use Steamos after end of life?

Accepted Answer

No. Running Steamos 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 Steamos release.

Question 4

How to upgrade from Steamos 2 to Steamos 3.x?

Accepted Answer

To upgrade Steamos from 2 to 3: (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 Steamos LTS version?

Accepted Answer

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

Question 6

How long does Steamos support each version?

Accepted Answer

On average, Steamos supports each release for approximately 34 months (~2.8 years).  The exact EOL date for each version is listed in the table above.
