### YugabyteDB version

By default, clusters are created using a stable release, taken from the [stable release series](../../../releases/versioning/#stable-releases) of YugabyteDB. You can choose to deploy your dedicated cluster using the following tracks:
Clusters are created using a stable release, taken from the [stable release series](../../../releases/versioning/#stable-releases) of YugabyteDB. You can choose to deploy your dedicated cluster using the following tracks:

- Production - Has less frequent updates, using select stable builds that have been tested longer in YugabyteDB Aeon.
- Innovation - Updated more frequently, providing quicker access to new features.
- Early Access - Updated more frequently, providing access to the most recent stable YugabyteDB release.

If you need a feature from the [preview release series](../../../releases/versioning/#preview-releases) of YugabyteDB, contact {{% support-cloud %}} before you create your cluster. (Preview is also available for Sandbox clusters.)
- Extended - Has less frequent updates, using mature [LTS releases](../../../releases/versioning/#stable-release-support-policy) that have been tested longer in YugabyteDB Aeon.
- Rapid - Updated more frequently, providing quicker access to new features. Rapid can include [STS and LTS releases](../../../releases/versioning/#stable-release-support-policy), depending on which is more recent.

Yugabyte manages upgrades for you. After you choose a track, database upgrades continue to take releases from the track you chose. For multi-node clusters, Yugabyte performs a rolling upgrade without any downtime. You can manage when Yugabyte performs maintenance and upgrades by configuring the [maintenance window](../../cloud-clusters/cloud-maintenance/) for your cluster.
