## 滚动升级改动

- 由于 [#4085](https://github.com/pingcap/tidb-operator/pull/4085) 的改动，升级 TiDB Operator 会导致 TidbMonitor Pod 删除重建

## 新功能

- 支持设置 `Backup` Job 的 `priorityClassName` ([#4078](https://github.com/pingcap/tidb-operator/pull/4078), [@mikechengwei](https://github.com/mikechengwei))
