# Migrating to libp2p@33 A migration guide for refactoring your application code from libp2p v0.32.x to v0.33.0. ## Table of Contents - [Module Updates](#module-updates) ## 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.
