- Support configuring init container `resources` for TiFlash ([#4304](https://github.com/pingcap/tidb-operator/pull/4304), [@KanShiori](https://github.com/KanShiori))
- Support configuring the `ssl-ca` parameter for TiDB via `TiDBTLSClient` to disable client authentication ([#4270](https://github.com/pingcap/tidb-operator/pull/4270), [@just1900](https://github.com/just1900))
