This page lists the release notes of [TiDB Cloud](https://www.pingcap.com/tidb-cloud/) in 2024.

## December 3, 2024

**General changes**

- Regional high availability (beta) for [TiDB Cloud Serverless](/tidb-cloud/select-cluster-tier.md#tidb-cloud-serverless) clusters.

This feature is designed for workloads that require maximum infrastructure redundancy and business continuity. Key features include:

- Nodes are distributed across multiple availability zones to ensure high availability in the event of a zone failure.
- Critical OLTP (Online Transactional Processing) components, such as PD and TiKV, are replicated across availability zones for redundancy.
- Automatic failover minimizes service disruption during a primary zone failure.

This feature is currently available only in the AWS Tokyo (`ap-northeast-1`) region and can be enabled only during cluster creation.

For more information, see [High Availability in TiDB Cloud Serverless](/tidb-cloud/serverless-high-availability.md).

- Introduce the Recovery Group feature (beta) for disaster recovery of [TiDB Cloud Dedicated](/tidb-cloud/select-cluster-tier.md#tidb-cloud-dedicated) clusters deployed on AWS.

This feature enables you to replicate your databases between TiDB Cloud Dedicated clusters, ensuring rapid recovery in the event of a regional disaster. If you are in the Project Owner role, you can enable this feature by creating a new recovery group and assigning databases to the group. By replicating databases with recovery groups, you can improve disaster readiness, meet stricter availability SLAs, and achieve more aggressive Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO).

For more information, see [Get started with recovery groups](/tidb-cloud/recovery-group-get-started.md).
