 > :warning: In version 4.1.0 we moved our subpackages from `@node-redis` to `@redis`. If you're just using `npm install redis`, you don't need to do anything—it'll upgrade automatically. If you're using the subpackages directly, you'll need to point to the new scope (e.g. `@redis/client` instead of `@node-redis/client`).
