# TiDB Operator 1.5.4 Release Notes

Release date: September 13, 2024

TiDB Operator version: 1.5.4

## Improvements

- The VolumeReplace feature supports customizing the number of spare replicas for PD and TiKV ([#5666](https://github.com/pingcap/tidb-operator/pull/5666), [@anish-db](https://github.com/anish-db))
- The VolumeReplace feature can be enabled for specific TiDB clusters ([#5670](https://github.com/pingcap/tidb-operator/pull/5670), [@rajsuvariya](https://github.com/rajsuvariya))
- EBS snapshot restore supports configuring whether to terminate the entire restore task immediately if volume warmup fails ([#5622](https://github.com/pingcap/tidb-operator/pull/5622), [@michaelmdeng](https://github.com/michaelmdeng))
- When using the `check-wal-only` warmup strategy, EBS snapshot restore marks the entire restore task as failed if warmup fails ([#5621](https://github.com/pingcap/tidb-operator/pull/5621), [@michaelmdeng](https://github.com/michaelmdeng))
