# Feature stages

MotherDuck features go through lifecycle stages before they are considered stable and production-ready.

## Preview

A feature in **preview** is available for use but may be operationally incomplete.
Preview features:

- May have limited backward compatibility
- Are subject to change without notice
- Are not covered by MotherDuck's SLA
- May have limited support

Preview features are a great way to try out new functionality and provide feedback.
If you have questions or feedback about a preview feature, connect with us in our [Community Slack](https://slack.motherduck.com/) or email support@motherduck.com.

## Generally Available (GA)

A feature that is **generally available** is stable, production-ready, and fully supported.
GA features:

- Have full backward compatibility guarantees
- Are covered by MotherDuck's SLA
- Receive full support
