 * Support for serverless and traditional web service architectures with **Unisocket** and **Smart** operation modes
 * Ability to listen client lifecycle, cluster state and distributed data structure events
 * and [many more](https://hazelcast.org/imdg/clients-languages/node-js/#client-features).
 
-> *: Make sure to use 3.x versions of Hazelcast Node.js client and IMDG to access these primitives as the work to support them in 4.x versions is in progress.
