+# TiDB Operator 1.6.1 Release Notes
+
+Release date: Dec 6, 2024
+
+TiDB Operator version: 1.6.1
+
+## New features
+
+- Support Backup & Restore using Azure blob storage SAS token authentication ([#5720](https://github.com/pingcap/tidb-operator/pull/5720), [@tennix](https://github.com/tennix))
+- VolumeReplace feature supports TiFlash ([#5685](https://github.com/pingcap/tidb-operator/pull/5685), [@rajsuvariya](https://github.com/rajsuvariya))
+
+## Improvements
+
+- VolumeModify feature no longer performs evict leader operations for TiKV to shorten the modification time ([#5826](https://github.com/pingcap/tidb-operator/pull/5826), [@csuzhangxc](https://github.com/csuzhangxc))
+- Support specifying the minimum wait time during the rolling update of PD Pods through annotations ([#5827](https://github.com/pingcap/tidb-operator/pull/5827), [@csuzhangxc](https://github.com/csuzhangxc))
+- 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))
+- Optimized the PD microservice transfer primary logic to reduce the number of transfer primary operations during component updates ([#5643](https://github.com/pingcap/tidb-operator/pull/5643), [@HuSharp](https://github.com/HuSharp))
+
+## Bug fixes
+
+- Fix the issue that EBS snapshot restore incorrectly succeeds when no TiKV instances are configured or TiKV replica is set to 0 ([#5659](https://github.com/pingcap/tidb-operator/pull/5659), [@BornChanger](https://github.com/BornChanger))
+- Fix the issue that the ClusterRole/ClusterRoleBinding corresponding to TidbMonitor monitoring multiple TiDB clusters across namespaces was not properly cleaned up after deletion ([#5956](https://github.com/pingcap/tidb-operator/pull/5956), [@csuzhangxc](https://github.com/csuzhangxc))
