## Clients

**NOTE**: Because of package manager caching, it may take a few
minutes after the release for this version to appear in the package
manager.

You cannot run a newer client against an older cluster: clients are only compatible
with replicas from their own release *or newer*, subject to the newer release's
`Oldest supported client version`.
