MVP: Have a look, consider whether this can help you in the future.
Beta: You can benefit from this, but you should carefully evaluate the feature.
Ready and Evolving: Ready to use in production, but be aware you may need to make some adjustments to your application and setup in the future, when you upgrade Flink.
Stable: Unrestricted use in production
Reaching End-of-Life: Stable, still feel free to use, but think about alternatives. Not a good match for new long-lived projects.
