## Compatibility changes <!--tw@qiancai 2 条-->

- TiKV 中提供 RocksDB [`track-and-verify-wals-in-manifest`](https://docs.pingcap.com/zh/tidb/v6.5/tikv-configuration-file#track-and-verify-wals-in-manifest-从-v659-版本开始引入) 配置,用于调查 WAL (Write Ahead Log) 可能损坏问题 [#16549](https://github.com/tikv/tikv/issues/16549) @[v01dstar](https://github.com/v01dstar)
- DR Auto-Sync 支持设置 [`wait-recover-timeout`](https://docs.pingcap.com/zh/tidb/v6.5/two-data-centers-in-one-city-deployment#启用自适应同步模式),用于控制当网络恢复后切换回 `sync-recover` 状态的等待时间 [#6295](https://github.com/tikv/pd/issues/6295) @[disksing](https://github.com/disksing)
- Add a TiKV configuration item [`track-and-verify-wals-in-manifest`](https://docs.pingcap.com/tidb/v6.5/tikv-configuration-file#track-and-verify-wals-in-manifest-new-in-v659) for RocksDB, which helps you investigate possible corruption of Write Ahead Log (WAL) [#16549](https://github.com/tikv/tikv/issues/16549) @[v01dstar](https://github.com/v01dstar)
- DR Auto-Sync support configuring [`wait-recover-timeout`](https://docs.pingcap.com/tidb/v6.5/two-data-centers-in-one-city-deployment#enable-the-dr-auto-sync-mode), which enables you to control the waiting time for switching back to the `sync-recover` status after the network recovers [#6295](https://github.com/tikv/pd/issues/6295) @[disksing](https://github.com/disksing)
