## Module Updates

Libp2p uses a datastore implementation for Peerstore persistence and for the DHT state. While libp2p defaults to a datastore implementation, it can receive any implementation of a datastore compliant with the [interface-datastore](https://github.com/ipfs/js-ipfs-interfaces/tree/master/packages/interface-datastore) via its configuration.

In this release, we updated to `interface-datastore@6.0.0`. As a result, libp2p users relying on a configured datastore should update it to a compliant implementation for updating libp2p.
