Release channels allow you to select between stable\nfeatures and newer experimental features. You can select the release channel\nwhen you create a Dataproc Metastore service.\n\nTypes of release channels\n-------------------------\n\nThere are two types of release channels:\n\n- **Canary** : The `Canary` release channel contains the newest features, which\n may be unstable and subject to unresolved issues with no known workarounds.\n Services using `Canary` are not subject to any SLAs.\n\n- **Stable** : The `Stable` release channel contains features that are considered\n stable and have been validated for production use.\n\nIf you don't specify a channel, new Dataproc Metastore services are created with the\n`Stable` value. If you select the `Canary`\nrelease channel, then you automatically receive the newer features.\n\nRelease notes\n-------------\n\nTo learn what's new in a release channel, review the following release notes:\n\nWhat's next\n-----------\n\n- [Create a service](/dataproc-metastore/docs/create-service)\n- [Release notes](/dataproc-metastore/docs/release-notes)\n- [Version policy](/dataproc-metastore/docs/version-policy)"]]
