Unstable

The API is in the process of settling, but has not yet had sufficient real-world testing to be considered stable.

Changes will not be announced. We recommend using the watch function for the given page to stay updated.

Stable

The API has proven satisfactory, but cleanup in the underlying code may cause minor changes. Backwards-compatibility will be maintained if reasonable.

Changes will be announced in the release notes.

Frozen

This API has been tested extensively in production and is unlikely to ever have to change. Backwards-compatibility is guaranteed.

Changes will be announced in the release notes, parallel versions will be maintained for two major releases.

In creating this we were inspired by the node.js stability index. Thanks a lot, you rock.
