+## Deprecated features
+
++ [Mydumper](https://docs.pingcap.com/tidb/v4.0/mydumper-overview) will be deprecated in v7.5.0 and most of its features have been replaced by [Dumpling](/dumpling-overview.md). It is strongly recommended that you use Dumpling instead of mydumper.
++ TiKV-importer will be deprecated in v7.5.0. It is strongly recommended that you use the [Physical Import Mode of TiDB Lightning](/tidb-lightning/tidb-lightning-physical-import-mode.md) as an alternative.
