     It is recommended to specify the version number of TiProxy in the topology configuration so that TiProxy will not be upgraded when you upgrade the TiDB cluster through [`tiup cluster upgrade`](/tiup/tiup-component-cluster-upgrade.md). Otherwise, the client connection might be disconnected during TiProxy upgrade.
